Investigation of CMAS Resistance of Sacrificial Suspension Sprayed Alumina Topcoats on EB-PVD 7YSZ Layers
- 43 Downloads
Molten calcium–magnesium–aluminum–silicate (CMAS) mineral particles cause significant degradation of thermal barrier coatings (TBCs) in aero-engines. One approach to protect the TBC coating against the CMAS attack is the application of a sacrificial coating on top of the TBC coating. In this work, Al2O3 coatings were deposited on EB-PVD 7YSZ layers using suspension plasma spraying (SPS) and suspension high velocity oxy-fuel spraying (SHVOF), in order to produce sacrificial topcoats with two different microstructures and porosity levels. The coating systems were tested under CMAS attack with one natural volcanic ash and two artificial CMAS powders by conducting infiltration tests at 1250 °C in the time intervals between 5 min and 10 h. It was found that the porosity and morphology of suspension sprayed alumina topcoats, the chemical composition of the deposits and the infiltration conditions strongly influence the CMAS infiltration, reaction kinetics and formation of the reaction products. While the porous SPS coatings offer limited resistance against CMAS infiltration, the dense SHVOF coatings show promising CMAS sealing behavior. Among the formed reaction products, only (Fe, Mg) Al spinel acted as an efficient barrier against CMAS infiltration. However, the formation of uniform spinel layers strongly depends on the pore morphology of the sacrificial coating and the CMAS chemistry.

Study on Generation of Fine Grained Titanium Aluminide Through Ball Milling of Ti, Al and Ni-P Coated Graphite Powder
High energy ball milling (HEBM) had been carried out to produce submicron size titanium aluminide intermetallics (TiAl) using elemental powders of Ti and Al alongwith Ni-P coated graphite. 1% graphite powders was added to stoichiometric composition of Ti48Al and ball milling was conducted for different milling time at varying rpm. The effect of milling time and rpm on particle size has been studied. The prepared samples have been characterized using X-ray diffraction, differential scanning calorimetry (DSC) and scaning elecron microscopy (SEM). Grain size as low as 500 nm could be achieved. Formation of Ti3Al, TiAl and carbon containing intermetallic compounds had been confirmed through X-ray diffraction. Milling time and rpm of mill is found to be important factors which control the final particle size.

A fiber optic displacement sensor (FODS) using a transmission technique was developed to detect sugar contents in honey. This was achieved by measuring the output signal of non- and adulterated honey with different addition percentage volumes of sugar (fructose and glucose). Five types of honey samples were adulterated with different percentages of fructose and glucose ranging from 0% to 10%. Blue diode laser at 435 nm was used as a light source in this FODS. The performance of sensor showed that the voltage signal linearly increased with the concentration of adulteration of sugar. In contrast, the refractive index of the adulterated honey is found decreasing with the concentration of sugar. This means the higher sugar contents in adulterated honey the lower is the refractive index leading to high transmission in FODS. Thus, FODS based on a transmission technique has a potential to detect the sugar content in adulterated honey. The simplicity, faster, and cost effective made FODS as a promising technique for food industry.

- An overview of a research on Vitis vinifera plants treated with a chemical (calcium and magnesium ions) and biological (Trichoderma viride) agents simultaneously loaded in alginate microspheres was presented. Microspheres were applied at two growth stages: before flowering and berries pea-size. Physicochemical characteristics of leaves after the two growth stages and grapes were measured in terms of bioactive components content and antioxidant activity. After the treatments, vine leaves reached a significant increase in almost all measured parameters (polyphenols, antioxidant capacity, β-carotene, and chlorophyll) compared to the control. The highest total chlorophyll content was found after the treatment with microspheres containing Mg²⁺/Ca²⁺ cations, and T. viride. The treatments enhanced Vitis vinifera leaves in terms of bioactive potential and can be further used as a functional food. As compared to the control, somewhat elevated values of total polyphenols and antioxidant activity were found on the grape samples. | Yes |
Isabel Wiltshire reflects on this summer’s interdisciplinary research internship, which brought chemistry together with the history of medicine; the project was supervised by Dr Victoria Bates (history) and Dr Jenny Slaughter (chemistry).
How can chemistry be used to write history? This was the question that I set out to answer this summer, using the contents of a Victorian medicine cabinet discovered at Tyntesfield House in North Somerset. This cabinet was the property of the Gibbs family who were prosperous traders and contains over 150 bottles; the contents of the cabinet ranged from medicinal ingredients to prescriptions and ‘quack’ medicines. The School of Chemistry of the University of Bristol has been involved in the safe cleaning of the bottles contained within it, many of which contained poisons and dangerous substances. I am a third year undergraduate chemistry student and have investigated the cabinet as part of an interdisciplinary project between the School of Chemistry and the Department of History.
It has become apparent, as I reach the end, that this project was far more history-based than chemistry-based, despite my initial introduction to it being through the School of Chemistry. This was inevitable really, when dealing with a Victorian artefact. However, when starting out, the sheer size of the task was daunting: I had never done historical research or studied history at any great length. Where to start? I went about the historical research the way I would go about researching a lab report. After three years of studying chemistry, I sure know how to type a keyword into a database. It turned out, of course, to be a lot harder than that. There was in fact very little literature on the exact area of history I was interested in: self-care in Victorian England. I wanted to know what happened after the doctor left, or before he would even have been called out. I started big, trying to gain a general idea of what medicine and sickness were like at the time, because I really don’t have a historical backing to start from; this process was pretty much the equivalent of reading a chemistry textbook before starting a research project because you don’t know what molecules are. I could then start going into detail about particular areas that, together, would give me an idea of how Victorians treated themselves when ill. This research covered pharmacists, opium and quackery, to name but a few, and focused initially on books and papers published by historians. Finally I got down to the primary sources, many of which are quite different from a primary source in science. My historical primary sources included diary entries and newspapers, whereas a primary source in chemistry would generally be a journal article, peer-reviewed and presenting the latest research in that field. I found the historical primary sources to be often amusing and horrifying in equal measures (I would recommend the seminal tome, Memoirs of a Stomach to anyone). It was certainly a challenge to apply my chemistry skills to a historical problem, but my background as a science student didn’t hinder my research. Any skills I have in research I believe I obtained by studying chemistry. Despite disciplinary differences, in both chemistry and history it is possible to take a medical cabinet as a ‘source’: a starting point for research. By using my skills in chemistry to analyse the medicine itself, instead of just historical books about medicine, I could gain unique insights into the history of medicine. The historical research led me to choose three bottles from the cabinet to sample. Each would be an example of a different aspect of self-care and the medical marketplace in Victorian Britain. Determining the different categories came from the observations of the different bottles and the historical research undertaken. Both complemented each other: seeing that the cabinet contained many tinctures and spirits of herbs and flowers correlated with contemporary and historiographical reports of traditional medicines still being used in ‘modernity’, for instance. The interdisciplinary aspect of the project was essential at this point: chemical analysis was important for identifying what types of medicines were being used; research into the preparation and uses of the different medicines was essential for making this analysis historiographical meaningful. Here, chemistry and history needed to work in tandem. The meeting of chemistry and history is possibly a strange one, but I believe that there is much to be learned by utilizing scientific resources, notably analytical techniques, to aid historical research. | Yes |

According to the U.S. Food and Drug Administration, polysorbate 60 is a food additive most commonly used as an emulsifier to keep oil and water from separating in dessert toppings and imitation coffee creamers. Polysorbate 60 is often found in baked goods and frozen desserts for moisture retention.Know More
Polysorbate 60 is formed by reacting a mixture of stearic acid, sorbitol and ethylene oxide. It comes in the form of a yellow paste for easy mixing with oil and fats. Its addition to imitation coffee creamers allows the water-based coffee and the oil-based creamer to mix thoroughly. Natural creamers usually separate from coffee because oil and water do not mix.
According to the FDA, polysorbate 60 is safe for consumption. When it is used as an emulsifier in dessert toppings, polysorbate 60 is commonly mixed with one or all of the following additives: sorbitan monostearate, polysorbate 65 or polysorbate 80. However, the amount of polysorbate 60 cannot exceed 0.4 percent of the final weight of the topping. When used in baked goods, polysorbate 60 is commonly added along with sorbitan monostearate or polysorbate 65. In this case, when used alone or in combination with the other two additives, the amount of the additive cannot exceed 0.46 percent of the cake mix’s final dry weight. Polysorbate 60 is also known as PEG-60, TWEEN-60 and polyoxyethylene-(20)-sorbitan monostearate.Learn more about Chemistry

Recombinant Human Fucosyltransferase 11/FUT11 Protein, CF SummaryLearn more about Fluorescent Glycan Labeling and Detection
Gly25-Leu492, with an N-terminal 6-His tag
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Fucosyltransferase 11/FUT11
Fucose is frequently found at terminal sites on various glycans and is essential for the generation of many sugar epitopes. Well-known fucose containing glycans include Lewis and ABO blood group antigens. Lewis epitopes are key elements involved in leukocyte homing and extravasation process, thus are essential for lymphocyte maturation and natural defense functions (1). O-fucosylation on Notch receptor is found to be essential for its signaling function (2). So far, 11 carbohydrate specific fucosyltransferases are found in humans (3). FUT1 and FUT2 are alpha 1-2 fucosyltransferases and are responsible for ABO blood group antigen synthesis (4). FUT3, FUT4, FUT5, FUT6, FUT7 and FUT9 are alpha 1-3/4 fucosyltransferases and are responsible for Lewis antigen generation (5). FUT10 and FUT11 are newly cloned alpha 1-3 fucosyltransferases that are distinct from the alpha 1-3/4 fucosyltransferase subfamily and are able to introduce fucose to the innermost core GlcNAc of the N-glycan on conalbumin glycopeptides and biantennary N-glycan acceptors but not onto short lactosaminyl acceptor substrates (6). Predicted as a type II transmembrane protein and a Golgi resident enzyme, the exact function of this enzyme needs to be further characterized. The activity of this enzyme has been measured with a phosphatasecoupled method (7).

NC Child and Toxic Free NC have joined with concerned parents and local health advocates to ask major retailers to stop selling canned foods packaged with toxic bisphenol A (BPA), a chemical that has been linked to many health problems for children. Federal and state authorities have declined to move quickly to require safe packaging, so we are calling on Kroger and its subsidiaries—like NC-based Harris Teeter—to eliminate BPA from its canned goods, and replace it with a safe alternative.
BPA is a dangerous synthetic chemical that disrupts the endocrine system and mimics the hormone estrogen. More than 300 animal and human studies have linked BPA exposure to a number of health problems, including breast and prostate cancer, asthma, obesity, behavioral changes and weakening of the immune system, and lowered sperm counts. For children in particular, BPA is associated with low birth weight, altered development of the brain, and attention deficit disorder.
A recent report, Buyer Beware: Toxic BPA and regrettable substitutes found in the linings of canned food, showed 62 percent of the Kroger products sampled (13 out of 21) tested positive for BPA-based epoxy resins. Of the Kroger products tested, two Harris Teeter brand cans tested positive (six Harris Teeter brand cans were tested total).
Unfortunately, seeking out products labeled “BPA free” may be another invitation to health concerns. Many retailers and national brands are phasing out BPA, but many are replacing it with harmful substitutes. For example, many cans tested for the Buyer Beware report were lined with a PVC-based polymer. These can linings are made from highly hazardous chemicals including vinyl chloride, a known human carcinogen. Meanwhile, BPS—another common replacement for BPA—can elicit endocrine effects similar to BPA.
Kroger and Harris Teeter should commit to eliminating BPA from food cans sold in their stores and establish clear timelines and benchmarks for a transition to safer alternatives. The retailers should also work with their suppliers to ensure that BPA is not replaced with dangerous chemicals. All chemicals used in can linings should be fully disclosed to ensure consumer safety. Lastly, Kroger, Harris Teeter, and other retailers should adopt a comprehensive chemical policy to safely replace other chemicals of concern in their products and packaging.
There are a few things consumers can do to protect their families until retailers commit to safer product packaging:
Vote with your pocketbook. Only purchase canned food from manufacturers and retailers that exercise complete transparency about what chemicals are used in their canned food packaging.
Avoid canned goods and eat fresh when possible. In general, food that requires less processing and packaging materials will be less-toxic. Think dried beans as opposed to canned. When eating fresh or minimally processed foods isn’t possible, choose frozen food, food stored in glass jars, or food stored in aseptic packaging—i.e. those cartons you find products like milk, soup, and chopped tomatoes in.

This study aimed to analyze the mineral composition of naturally- and artificially-produced caries-affected root dentin and to determine the elemental incorporation of resin-modified glass ionomer (RMGI) into the demineralized dentin.
Materials and methods
Box-formed cavities were prepared on buccal and lingual root surfaces of extracted sound human premolars (n = 15). One cavity was exposed to a microbial caries model using a strain of Streptococcus mutans. The other cavity was subjected to a chemical model under pH cycling. Premolars and molars with root surface caries were used as a natural caries model (n = 15). Outer caries lesion was removed using a carbide bur and a hand excavator under a dying technique and restored with RMGI (Fuji Ⅱ LC, GC Corp.). The weight percentages of calcium (Ca), phosphate (P), and strontium (Sr) and the widths of demineralized dentin were determined by electron probe microanalysis and statistically analyzed using ANOVA and Tukeys post hoc test (α = 0.05).
Demineralized surface was observed under SEM in all samples. Artificial models induced greater losses of Ca and P and larger widths of demineralized dentin than did a natural caries model (p < 0.05). Sr was diffused into the demineralized dentin layer from RMGI.
Both the microbial and the chemical caries models produced similar patterns of mineral composition on the caries-affected dentin. However, within the limitation of this study, the artificial lesions had a relatively larger extent of demineralization than the natural lesions. Sr from RMGI was incorporated into the superficial layer of the caries-affected dentin. | Yes |

I came across a question a while back. It stated that a oil droplet was suspended vertically within an electric field. The man who suspended it had left to eat a very LONG lunch, and came back to see that it was splattered on the top plate (nothing with the setup had changed), and the question asked us to state a physical reason for such an event. I thought it was because of a transfer of momentum from electrons moving from the negative plate on the bottom to the positive plate on top, which just so happened to collide with the oil droplet. Someone else answered saying that the droplet evaporated slightly, which caused it's mass to decrease and so the force acting upon it managed to accelerate it more than that of gravity, causing it to move upwards slowly. That was the correct solution, but I'm just a bit confused, since wouldn't it lose some charge when it evaporates as well? So overall the q/m ratio would still be the same? They said it was unlikely that it evaporated some of its charge, so I'm just wondering how the charge within an object is distributed. Is it distributed evenly throughout, or is it more concentrated in some areas?
You have to consider Gauss's law which says that the electric flux out of any closed surface is proportional to the charge enclosed by the surface regardless of the charge distribution.
Without more information, it sounds like in this case it is implied that volatility of the oil is sufficient to overcome any effect of the electric field or charge. As such, if the oil drop is able to expel molecules of oil, then those molecules would likely carry neutral charge.
Millikan used a similar set up in his oil drop experiment to determine the charge of the electron. His experiment was very sensitive to the mass of the oil which made him choose one with a low vapor pressure in order pass through the vacuum with minimal loss of mass due to evaporation. | Yes |
Reinforced Thermoplastic Pipe (RTP) and Thermoplastic Composite Pipe (TCP) Difference
What is RTP and TCP pipe ?
The reinforced thermoplastic pipe (RTP) as well known as flexible composite pipe (FCP) is generic term referring to a reliable high strength synthetic fiber (such as glass, aramid or carbon) or high strength steel wire reinforced pipe system. It is an alternative to
traditional pipelining materials. It consists of three basic layers including a thermoplastic liner, helically wrapped continuous high-strength fiber reinforcement and an external thermoplastic jacket.
Typically, the materials used in the construction of the pipe might be polyethylene (PE), PA11 or PVDF and may be reinforced with aramid or polyester fiber or high strength steel wire, although other combinations are used. It is available in coils up to 400 m (1,312 ft) in
length. The pipes are available in pressure ratings from 30 to 450 bar (3 to 45 MPa; 435 to 6,527 psi). Recent innovations include gas tight RTP and RTP for high operating temperatures.
The general RTP pipe is unbonded cause the holt-melt adhesive is made from Polyethylene (PE) matrix. The hot-melt adhesive is used to stick the inner lining and the outer jacket to the reinforced layer and it fully integrates with the HDPE when it is heated together. It is used in lower pressure and less demanding temperature applications compared to the fully bonded TCP (thermoplastic composite pipe).
The thermoplastic composite pipe (TCP), which named bonded-reinforcement structure of RTP pipe, also consist of reinforced thermoplastic composites, quite similar as general RTP pipes, they are suited to higher pressures and a greater temperature range for following reasons. First, some bonded RTP(TCP) uses higher performing thermoplastic resins, such as PEEK, and/or carbon fiber. Second, TCP pipe reinforcement layers are bonded to each other through melt-fusion, which yields higher performance properties than RTP made from the same materials.
What is the structure of the RTP pipe and TCP pipe ?
Both RTP pipe and TCP pipe comes up with three basic layers : an inner thermoplastic layer, a continuous fiber reinforcement wrapped around the pipe, and an outer thermoplastic layer.
Inner layer generally comes up with polyethylene (PE100), inner layer can also apply PERT-1, PERT-2, EVOH etc. material as core pipe (inner layer).
, RTP pipe reinforcement layer is unbonded structure, which consists of separate unbonded polymeric and metallic layers, which allows relative movement between layers.
TCP is bonded structure that all three layers are fully bonded with each other. bonded flexible pipes the reinforcement material ( such as fiberglass) is integrated and bonded to layers.
The major reinforcement material of RTP and TCP pipe ?
For non-metallic fiberglass reinforcement, both RCP and RTP pipe use the impregnated treatment fiberglass roving/tape as the reinforcement. The impregnation material is a kind of polyethylene friend material which has good bonding surface between PE and fiber. | Yes |
Climate-smart materials and production processes are at the top of the agenda for the aerospace industry. There is great interest in laser-based additive manufacturing with powder bed (L-PBF) as it can complement other manufacturing methods such as casting and forging. University West has been conducting cutting edge research in this manufacturing method for several years.
In simple terms, the component is built up by melting metal powder with laser as an energy source. The advantages of L-PBF are that you can produce products with more complex geometries and lighter designs more efficiently than with other methods. It requires less material and energy, it is faster and is more environmentally friendly. However, in order for the manufacturing method to be approved by the aerospace industry, it must meet the extreme standards on quality set by the industry.
First with research on weldability
With her recent dissertation, doctoral student Tahira Raza strengthens the university's already solid knowledge regarding additive manufacturing with L-PBF for alloy 718. She has looked at which process parameters work best for this manufacturing method and is the first to study the weldability of components built in alloy 718.
– Manufacturers want to be able to weld together small parts made with L-PBF to build larger, more complex components, such as parts for aircraft engines. A crucial factor is how the material is affected when welding in it. Materials react in different ways and it is necessary to eliminate defects in the final product, Tahira explains.
– In the microstructure formed in alloy 718 during production with the powder bed method, there are precipitations that can affect mechanical properties and weldability. It is primarily when these constituents are re-melted during welding that cracking can occur. I have researched how to avoid these cracks.
Advanced tests at Canadian University
Tahira has subjected the metal to different types of heat treatment before and after welding. She analyzed the test results using advanced electron microscopy at University of Manitoba, Canada, where she worked for three months. The tests showed, among other things, that the weldability deteriorated to varying degrees after the different heat treatments. The material became particularly sensitive to cracking when the component was subjected to hot isostatic pressing (HIP) prior to welding. It was also found that the welding direction, in relation to in what direction the component was constructed, significantly affects crack formation.
– It is difficult to completely avoid defects in products made by additive manufacture with powder bed. But with full control over where and how the defects occur, the manufacturing method can still be very relevant to the industry.
Colleagues are working on new research projects
– My work is a first step in increasing the knowledge about the weldability of these specific conditions. Much more research is needed to make the manufacturing method useful in industry. New projects have started within, for example, the research profile PODFAM, where other researchers are working on the effects of heat treatments in relation to the weldability of the powder bed materials.
Tahira has done her research in close collaboration with GKN Aerospace in Trollhättan. Among other things, the company designs, manufactures and maintains engine components for the aerospace industry.
– Additive manufacturing with powder bed opens the opportunity for GKN Aerospace to manufacture smaller engine parts and spare parts quickly, cost-effectively and with high levels of quality.
Inspires other students
Tahira is still doing research, but she is now focused on other additive manufacturing methods and other types of materials. She will also teach at University West's contract education programs, which is something she really looks forward to.
– I would like to inspire and motivate students and professionals in their studies. It means so much to have good coaching and support. I myself have benefited greatly from this during my five years as a doctoral student.
Tahira knows what good support can mean. Her journey has been impressive. As a single mother of four children, she chose to study Industrial Economics at University West and then dedicate herself to a career as a researcher.
– It has not been a straight and easy career path. But it does not matter, the main thing is not to give up.

Tailgas Thermal Oxidation
Regardless of the type of sulfur recovery process used (Modified Claus Process, Cold Bed Adsorption Process, or Modified Claus Process with Tailgas Cleanup), thermal oxidation of the tailgas is almost always the final processing step. Although catalytic oxidation of hydrogen sulfide (H2S) and other sulfur compounds is possible, thermal oxidation is by far the most widely used process due to its lower capital cost. In addition, the lower utility consumption of the catalytic process can often be offset by adding waste heat recovery to the thermal process.
Although many sulfur plant designers are experienced at designing thermal oxidizers to destroy H2S, recently there has been much attention focused in the U.S. on other contaminants found in sulfur plant and TGCU tailgas, such as carbon monoxide, nitrogen oxides, and hydrocarbons (particularly aromatic hydrocarbons). Field testing has shown that thermal oxidizers designed for H2S destruction are often woefully inadequate for destroying these other contaminants.
Ortloff has helped several plant operators to determine the source of these heretofore overlooked contaminants, and to redesign their thermal oxidizers to destroy the contaminants. As a result, Ortloff is uniquely qualified to design thermal oxidizers for compliance with today’s more stringent environmental regulations. Our thermal oxidizers are designed with the proper attention to feed introduction, burner design, operating temperature, and residence time to ensure almost complete destruction (95% or higher) of all these contaminants.
Thermal Oxidation without Waste Heat Recovery
For small thermal oxidizers (usually 20 LT/D or smaller), the capital expense of waste heat recovery is usually not justified by the value of the steam that could be produced. For these plants, a conventional incinerator is normally used.
1 – Heat is usually provided to the thermal oxidizer by combustion of fuel gas in a natural-draft burner, although forced-draft burners are sometimes used. The fuel gas flow rate is adjusted to maintain the furnace temperature at 1000°F or higher to ensure complete incineration of the sulfur compounds. Higher temperatures are usually required if carbon monoxide and and/or hydrocarbons in the feed to the thermal oxidizer must be incinerated. The burner operates with excess air to provide the free oxygen needed to incinerate the tailgas.
2 – The tailgas mixes directly with the burner effluent to heat the gas and mix it with the oxygen leaving the burner. The incinerator stack often includes a larger diameter bottom section to provide residence time for the high temperature oxidizing atmosphere to incinerate all of the sulfur compounds to sulfur dioxide (SO2).
3 – The hot effluent is then dispersed to the atmosphere from the top of the stack. The stack is normally equipped with ladders, platforms, and sampling ports to allow periodic stack testing. Environmental regulations may also require continuous monitoring of SO2 emissions.
Thermal Oxidation with Waste Heat Recovery
Cooling the thermal oxidizer effluent before dispersing the gas to the atmosphere is an efficient method of producing steam. If there is a use for the steam generated, the cost of the waste heat boiler can normally be justified by the savings in boiler fuel due to the steam produced from this “waste” heat, and by the cost savings from eliminating the refractory lined stack. (An externally insulated stack is used to disperse the effluent instead.)
Ortloff pioneered the use of waste heat boilers on the effluent from tailgas thermal oxidizers in the early 1970’s. Water-tube boilers are used to efficiently recover the maximum amount of heat, while careful design and attention to detail avoid potential sulfuric acid attack in the boiler or the downstream vent stack. Since sulfur plant tailgas and TGCU unit effluent ordinarily contain a considerable amount of combustibles, it is often possible to generate more steam in a thermal oxidizer waste heat boiler than is possible burning the same amount of fuel gas in an ordinary boiler. The incremental income from the steam produced will typically pay for the extra capital investment in less than a year.
1 – Heat is provided by combustion of fuel gas in a forced-draft burner. The burner operates with excess air to provide the free oxygen needed to incinerate the tailgas.
2 – The tailgas mixes directly with the burner effluent to heat the gas and mix it with the oxygen leaving the burner. The mixture enters a refractory-lined furnace to provide residence time for the high temperature oxidizing atmosphere to incinerate all of the sulfur compounds to SO2.
3 – The hot furnace effluent enters a water-tube boiler to generate high pressure (250 PSIG or higher) steam as the gas is cooled.
4 – The cooled boiler effluent is then dispersed to the atmosphere from the top of an insulated stack. Either the stack or its inlet line is normally equipped with sampling ports to allow periodic stack testing. Environmental regulations may also require continuous monitoring of SO2 emissions.
The decision of whether or not to apply waste heat recovery to thermal oxidizers depends on plant size and utility costs. Ortloff has performed many economic evaluations comparing thermal oxidizers with and without waste heat recovery, allowing us to quickly advise our clients on the optimum choice. | Yes |

عنوان مقاله [English]
Today, it is an inevitable necessity to make use of advanced and efficient technologies in order to increase productivity and gain a better economic status. Among different methods attracted the attention of researchers for enhancement in quantity and quality yield, cold plasma technique as a modern procedure has shown a promising prospects. Despite the importance of using cold plasma in agriculture, studies have focused more on the effect of this technique on reducing microbial load in agricultural products, less on absorption of nutrients in plants. Therefore, the objectives of this experiment were to evaluate the impacts of plasma treatment of corn seeds and plasma activated water (PAW) on growth and concentration of zinc and iron in the shoots of corn.
Materials and Methods
This research was conducted as a factorial experiment based on completely randomized design (CRD) with 3 replications in a research greenhouse in agricultural and natural resources research and education center of Khorasan Razavi. The factors of experiment were three types of seed (control seeds, seeds treated with dry plasma and wet plasma), two kinds of irrigation water (distilled water and PAW) and two levels of foliar spray (without foliar spray and foliar spray with iron and zinc). Required mass of soil, was gathered, air-dried, sieved from 5 mm mesh and weighted in 6 packs. Based on the soil test values the required macro, micronutrients (except for iron and zinc) was calculated and added to the soil, and then the soil samples were moved to the pot. PLASMA BIOTEC Company located in Khorasan Razavi Park of Sciences and Technology, Mashhad, Iran performed plasma treatment of seeds and water. Plasma treated corn seeds were planted on May 18th with a density of 6 seeds in each pot. Plantlets were reduced to 2 plants after germination and establishment and irrigation was continued with desired treatments. Shoots of each pot was cut 8 weeks after sowing, 1 cm above the ground and delivered to the laboratory, where the samples were washed, dried, grounded and the concentration of zinc and iron were measured using the atomic absorption device (Perkin Elmer, 2380) in dry ash digested in 2 N HCl acid. Data were statistically analyzed by SAS statistical software (version 9.4). Comparison of means for the main effects and interactions was performed by Tukey’s test at 5 percent confidence interval.
Results and Discussion
Comparison of means for the interaction effects of water × seed × foliar spray showed that the minimum concentration of iron (147.67 mg/kg) was observed in plants grown from non-treated seeds, not foliar sprayed and irrigated with non-PAW (treatment 1 in Table 7). On the other hand, plants grown from wet plasma treated seeds and received foliar spray showed the highest concentration of iron regardless of irrigation water type (treatments 10 and 12 in Table 7). Comparison of means also shows that iron concentration in plants grown from dry plasma treated seeds had no significant difference with that of non-treated seeds (treatments 1 and 5 or 2 and 6). The mean comparison results for zinc concentrations showed that the minimum value was related to plants grown from non-treated seeds, not foliar sprayed and irrigated with non-PAW (treatment 1 in Table 8). The comparison of the simple effects of the type of seed on the concentration of zinc in shoots (Table 6) showed that wet plasma seeds caused a significant increase in the concentration of zinc. However, comparison of means for the interaction effects of water × seed × foliar spray showed that the effect of plasma treatment on zinc concentration was effective only in treatments that received foliar spray (comparison of treatment 2 with 10 in table 8). Based on these results the highest zinc concentration was observed in plants grown from wet plasma seeds and received foliar spray at the same time (treatment 12 in Table 8). In addition, the comparison of treatment 1 with treatment 4 and treatment 9 with treatment 2 indicates that in order to increase the concentration of zinc in plant, plasma treatment of seeds cannot replace the foliar spray method. Comparison of means for the interaction effects of water × seed × Foliar spray showed that the minimum yield was observed in plants grown from non- treated seeds, irrigated with non- activated water and not sprayed with iron and zinc solution (treatment 1 in Table 9). However, the similar treatment which grown from wet plasma treated seeds (treatment 9), showed significantly higher yield. Dry plasma, without foliar spray and without PAW (treatment 5) had no significant priority over the control. Plants grown from seeds treated with wet plasma and without foliar spray could not significantly show more iron and zinc content over the control, while their shoot yield was higher.
Based on the findings of this study, it can be inferred that irrigation with PAW and utilizing seeds treated with dry plasma exhibited no significant impact on augmenting zinc and iron content, as well as shoot yield. Conversely, wet plasma treatment, while not yielding significant enhancements in the concentration of iron and zinc within the plant, did result in increased yield. It is crucial to note that the extent of influence exerted by factors such as frequency and duration of seed exposure to plasma conditions on the observed outcomes may vary significantly. Therefore, optimizing methodology and conducting further research in this domain are imperative for a comprehensive understanding of these processes.

A planned demonstration carbon capture plant at the European CO2 Technology Centre Mongstad (TCM) in Norway will be the first of its kind to treat flue gas from a gas-fired power plant. The plant will be engineered and constructed following a contract between Alstom and StatoilHydro, with Alstom supplying and installing the plant, and StatoilHydro ASA carrying out the operation. The plant is due to be operational in November 2011, and will use chilled ammonia post-combustion technology to capture carbon dioxide from the flue gases of a combined heat and power plant at Mongstad. It will also treat flue gases from a petroleum processing plant at the nearby Mongstad refinery, which has a carbon dioxide output equal to that of a coal-fired power plant. The TCM facility at Mongstad is the largest planned demonstration facility of its kind, with an annual capacity to capture of up to 100,000 tonnes of carbon dioxide, says Alstom. Of this, the chilled ammonia technology has the potential to capture up to 80,000 tonnes, and the project will aim to qualify the technology for the large-scale, cost-efficient treatment of flue gases.

Our Research Interests...
Nature is capable of synthesising a diverse range of highly functionalised and complex molecular architectures, starting from a limited set of building blocks. In all but a handful of cases these reactions are catalysed by enzymes, which often mediate these transformations with unparalleled selectivity. Enzymes can offer a sustainable and cost-effective alternative to more traditional chemical catalysis and are attractive tools for the pharmaceutical and fine chemical industry. Recent advances in protein engineering and DNA technologies have enabled the development of biocatalysts with enhanced substrate scope and with properties suitable for industrial application. Our research interests focus on the engineering and application of a more diverse pool of biocatalysts and the design of efficient industrial biocatalytic processes.
The sustainable synthesis of chiral amines remains a key research priority and the broad substrate scope and high degrees of regio- and stereoselectivity associated with transaminases (TAs) makes them ideal biocatalysts for the synthesis of optically pure amines. One of our main research areas involves the development of TA biocatalysts which enable the synthesis of a diverse range of chiral amines, starting from simple prochiral ketone precursors, in a highly sustainable manner. An important aspect of this involves engineering these enzymes to accept ‘smart’ amine donors that effectively displace the challenging reaction equilibrium. We also focus on the development of efficient high-throughput screening methods for the detection of novel TA activity.
We also have projects that exploit enzymes including cytochrome P450s, aldolases and ene-reductases and will add some details on these projects as they develop. | Yes |

article When you’re looking for a new treatment for a specific cancer diagnosis, there’s one thing you can count on: the Chinese herbs will deliver.
Here are some of the most common treatments for cancer and how you can find one that suits your needs.1.
Herbal Tea – a traditional Chinese medicineThe Chinese word for tea is yang, which is a combination of the letters 反 (yín) and 香 (zhǔ).
In Chinese, the word for water is 麼 (zhàng), which means water.
As we learned earlier, water is the lifeblood of our bodies.
Water is also vital for digestion, skin, and hair.
When water is depleted, the cells become more susceptible to infection.
If you want to boost the immune system and boost your immune function, drinking lots of water is a must.2.
Herbs for the treatment of asthma – herbal remediesOne of the best ways to reduce asthma is to use a variety of herbal remedies.
One of the herbal medicines that can be used to treat asthma is the Chinese herbal tea, yang.
This herbal tea is an ancient Chinese medicine that was given to people during the Han Dynasty (618-907 B.C.) for asthma.
It contains many of the same ingredients as tea, but it is made from plants that are known as herbal herbs.3.
The Chinese herbal remedy for cancer: the herbal medicine nyak, a Chinese herbal compoundThe Chinese medicine known as yak, is a Chinese herb that contains many other important plant compounds.
In the early 1900s, researchers discovered a plant compound that had a unique ability to slow cancer growth in animals.
The compound, called nyacin, was also found to have anti-inflammatory properties and anti-malarial properties.
It also had an anti-oxidant and antioxidant properties.
The Chinese people in the 19th century discovered that this compound was used in the treatment and treatment-related treatment of a number of cancers.4.
The herbal medicine used to fight the common cold – a tea containing a herbal medicineThat common cold is a common one for many people, especially for children.
It is caused by the bacterium Clostridium difficile.
However, some people who are sensitive to Clostrifolium, a common cold remedy, are allergic to the same bacterium.
One way to treat this is to drink tea that contains a herbal tea known as a nyuk.
This tea is made of various herbs, including nyas, nyāz, and yākou.
This herb is known as the traditional Chinese medicinal tea, the yang or yan-yan.
It’s an ancient and ancient remedy that is often found in Chinese hospitals and hospitals throughout China.5.
Herbals for the prevention of cancer – herbal treatmentsFor many people with cancer, the use of herbs and supplements can be the best option to prevent the disease.
For example, a study from the University of Chicago found that herbal treatments for colorectal cancer were more effective than standard chemotherapy drugs and radiation.
Other studies have shown that using herbal supplements can prevent and slow the progression of cancers in patients with lung cancer, lymphoma, melanoma, and pancreatic cancer.
In addition to herbs, other herbal products are often helpful in the prevention or treatment of cancer.
One study from University of Texas at Austin found that the use a blend of herbs was superior to the use only one herbal product.6.
Herbenic treatment for cancer – the Chinese medicine for leukemiaThe Chinese medicinal herbs used in treating leukemia are also used for the management of several other types of cancers, including skin cancer.
This Chinese medicine called the yin is often used for treating multiple types of cancer, including melanoma and melanoma subtypes.
The yin has several types of herbs in it, including xiaoshu, a herb called yīn, a compound called tian, and a number known as mòi, which means “mystic.”7.
Herbarium for cancer treatment – a herbal treatmentA herbal treatment can be an effective way to slow or even stop the spread of cancerous cells.
Many herbal treatments have the ability to bind with certain types of cells, including white blood cells, platelets, and macrophages.
The most common herbal treatment for melanoma is the herb bok choy, which has been used for a long time.
The bok is known to have some anti-cancer properties, which can be a major advantage when using a traditional herbal medicine to treat melanoma.8.
Herbinotherapy for cancer therapy – a Chinese medicine treatment for lung cancerA treatment that has been studied for cancer for many years is the herbal treatment called bok thong.
It was originally developed by Chinese scientists to treat cancer in the lungs, but its effectiveness has been found to be similar to | Yes |
Fats are one of the three main macronutrients, along with carbohydrates and proteins. Fat molecules consist of primarily carbon and hydrogen atoms and are therefore hydrophobic and are soluble in organic solvents and insoluble in water. Examples include cholesterol, phospholipids, and triglycerides.
|Types of fats in food|
The terms lipid, oil, and fat are often confused. Lipid is the general term, though a lipid is not necessarily a triglyceride. Oil normally refers to a lipid with short or unsaturated fatty acid chains that is liquid at room temperature, while fat (in the strict sense) specifically refers to lipids that are solids at room temperature – however, fat (in the broad sense) may be used in food science as a synonym for lipid.
Fat is an important foodstuff for many forms of life, and fats serve both structural and metabolic functions. They are a necessary part of the diet of most heterotrophs (including humans) and are the most energy dense, thus the most efficient form of energy storage.
Some fatty acids that are set free by the digestion of fats are called essential because they cannot be synthesized in the body from simpler constituents. There are two essential fatty acids (EFAs) in human nutrition: alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid). Other lipids needed by the body can be synthesized from these and other fats. Fats and other lipids are broken down in the body by enzymes called lipases produced in the pancreas.
Fats and oils are categorized according to the number and bonding of the carbon atoms in the aliphatic chain. Fats that are saturated fats have no double bonds between the carbons in the chain. Unsaturated fats have one or more double bonded carbons in the chain. The nomenclature is based on the non-acid (non-carbonyl) end of the chain. This end is called the omega end or the n-end. Thus alpha-linolenic acid is called an omega-3 fatty acid because the 3rd carbon from that end is the first double bonded carbon in the chain counting from that end. Some oils and fats have multiple double bonds and are therefore called polyunsaturated fats. Unsaturated fats can be further divided into cis fats, which are the most common in nature, and trans fats, which are rare in nature. Unsaturated fats can be altered by reaction with hydrogen effected by a catalyst. This action, called hydrogenation, tends to break all the double bonds and makes a fully saturated fat. To make vegetable shortening, then, liquid cis-unsaturated fats such as vegetable oils are hydrogenated to produce saturated fats, which have more desirable physical properties e.g., they melt at a desirable temperature (30–40 °C), and store well, whereas polyunsaturated oils go rancid when they react with oxygen in the air. However, trans fats are generated during hydrogenation as contaminants created by an unwanted side reaction on the catalyst during partial hydrogenation.
Saturated fats can stack themselves in a closely packed arrangement, so they can solidify easily and are typically solid at room temperature. For example, animal fats tallow and lard are high in saturated fatty acid content and are solids. Olive and linseed oils on the other hand are unsaturated and liquid. Fats serve both as energy sources for the body, and as stores for energy in excess of what the body needs immediately. Each gram of fat when burned or metabolized releases about 9 food calories (37 kJ = 8.8 kcal). Fats are broken down in the healthy body to release their constituents, glycerol and fatty acids. Glycerol itself can be converted to glucose by the liver and so become a source of energy.
There are many different kinds of fats, but each is a variation on the same chemical structure. All fats are derivatives of fatty acids and glycerol. Most fats are glycerides, particularly triglycerides (triesters of glycerol). One chain of fatty acid is bonded to each of the three -OH groups of the glycerol by the reaction of the carboxyl end of the fatty acid (-COOH) with the alcohol; i.e. three chains per molecule. Water is eliminated and the carbons are linked by an -O- bond through dehydration synthesis. This process is called esterification and fats are therefore esters. As a simple visual illustration, if the kinks and angles of these chains were straightened out, the molecule would have the shape of a capital letter E. The fatty acids would each be a horizontal line; the glycerol "backbone" would be the vertical line that joins the horizontal lines. Fats therefore have "ester" bonds.
The properties of any specific fat molecule depend on the particular fatty acids that constitute it. Fatty acids form a family of compounds that are composed of increasing numbers of carbon atoms linked into a zig-zag chain (hydrogen atoms to the side). The more carbon atoms there are in any fatty acid, the longer its chain will be. Long chains are more susceptible to intermolecular forces of attraction (in this case, van der Waals forces), and so the longer ones melt at a higher temperature (melting point).
|trans Unsaturated (Example shown: Elaidic acid)||cis Unsaturated (Example shown: Oleic acid)||Saturated (Example shown: Stearic acid)|
|Elaidic acid is the principal trans unsaturated fatty acid often found in partially hydrogenated vegetable oils.||Oleic acid is a cis unsaturated fatty acid making up 55–80% of olive oil.||Stearic acid is a saturated fatty acid found in animal fats and is the intended product in full hydrogenation. Stearic acid is neither cis nor trans because it has no carbon-carbon double bonds.|
Fatty acid chains may also differ by length, often categorized as short to very long.
- Short-chain fatty acids (SCFA) are fatty acids with aliphatic tails of fewer than six carbons (i.e. butyric acid).
- Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6–12 carbons, which can form medium-chain triglycerides.
- Long-chain fatty acids (LCFA) are fatty acids with aliphatic tails of 13 to 21 carbons.
- Very long chain fatty acids (VLCFA) are fatty acids with aliphatic tails of 22 or more carbons.
Any of these aliphatic fatty acid chains may be glycerated and the resultant fats may have tails of different lengths from very short triformin to very long, e.g., cerotic acid, or hexacosanoic acid, a 26-carbon long-chain saturated fatty acid. Long chain fats are exemplified by tallow (lard) whose chains are 17 carbons long. Most fats found in food, whether vegetable or animal, are made up of medium to long-chain fatty acids, usually of equal or nearly equal length. Many cell types can use either glucose or fatty acids for this energy. In particular, heart and skeletal muscle prefer fatty acids. Despite long-standing assertions to the contrary, fatty acids can also be used as a source of fuel for brain cells.
Importance for living organisms
Fats are also sources of essential fatty acids, an important dietary requirement. They provide energy as noted above. Vitamins A, D, E, and K are fat-soluble, meaning they can only be digested, absorbed, and transported in conjunction with fats. Fats play a vital role in maintaining healthy skin and hair, insulating body organs against shock, maintaining body temperature, and promoting healthy cell function. Fat also serves as a useful buffer against a host of diseases. When a particular substance, whether chemical or biotic, reaches unsafe levels in the bloodstream, the body can effectively dilute—or at least maintain equilibrium of—the offending substances by storing it in new fat tissue. This helps to protect vital organs, until such time as the offending substances can be metabolized or removed from the body by such means as excretion, urination, accidental or intentional bloodletting, sebum excretion, and hair growth.
In animals, adipose tissue, or fatty tissue is the body's means of storing metabolic energy over extended periods of time. Adipocytes (fat cells) store fat derived from the diet and from liver metabolism. Under energy stress these cells may degrade their stored fat to supply fatty acids and also glycerol to the circulation. These metabolic activities are regulated by several hormones (e.g., insulin, glucagon and epinephrine). Adipose tissue also secretes the hormone leptin.
The location of the tissue determines its metabolic profile: visceral fat is located within the abdominal wall (i.e., beneath the wall of abdominal muscle) whereas "subcutaneous fat" is located beneath the skin (and includes fat that is located in the abdominal area beneath the skin but above the abdominal muscle wall). Visceral fat was recently discovered to be a significant producer of signaling chemicals (i.e., hormones), among which several are involved in inflammatory tissue responses. One of these is resistin which has been linked to obesity, insulin resistance, and Type 2 diabetes. This latter result is currently controversial, and there have been reputable studies supporting all sides on the issue.
Fatty acids and human health
Dietary consumption of fatty acids has effects on human health. Studies have found that replacing saturated fats with cis unsaturated fats in the diet reduces risk of cardiovascular disease. For example, a 2015 systematic review of randomized control trials by the Cochrane Library concluded: "Lifestyle advice to all those at risk of cardiovascular disease and to lower risk population groups should continue to include permanent reduction of dietary saturated fat and partial replacement by unsaturated fats."
Numerous studies have also found that consumption of trans fats increases risk of cardiovascular disease. The Harvard School of Public Health advises that replacing trans fats and saturated fats with cis monounsaturated and polyunsaturated fats is beneficial for health. a 2014 meta-analyses of randomized controlled trials found that reducing fat and cholesterol intake does not affect cardiovascular disease or all cause mortality.

We investigate the thermo-optical and vacuum-ultraviolet properties of thin silicon carbide (SiC) coatings on transparent substrates in view of their use for Solar Orbiter remote sensing VUV instrumentation. We have made experimental studies with thin SiC coatings on quartz plates to evaluate their reflective properties in the VUV spectral range between 58 nm and 123 nm. We discuss the results in relation to the visible and near infrared optical properties of the samples. A thin SiC coating of 10 nm thickness is shown to be a very promising compromise between high VUV reflectivity and low vis/IR absorption. The overall absorption of the solar spectrum by such a mirror is less than 8 %. This will be beneficial for instruments requiring a large aperture due to diffraction and radiometric limitation, in coping with the thermal heat load during the Solar Orbiter mission. As an example, we propose a design of the primary telescope mirror for the Extreme Ultraviolet Spectrome ter(EUS). | Yes |

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of half-lives is radioactive dating. This has to do with figuring out the age of ancient things. It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge. It takes a certain amount of time for half the atoms in a sample to decay. It then takes the same isotope radiometric dating of time for half the remaining radioactive atoms to decay, and the same amount of time for half of those remaining radioactive atoms to decay, and so on.
If you want to know how old someone or something is, you can generally rely on some combination of simply asking questions or Googling to arrive at an accurate answer. This applies to everything from the age of a classmate isotope radiometric dating the number of years the United States has existed as a sovereign nation and counting as of But what about the ages of objects of antiquity, from a newly discovered fossil to the very age of the Earth itself? Sure, you can scour the Internet and learn rather quickly that the scientific consensus pins the age of of the planet at about 4. But Google didn't invent this number; instead, human ingenuity and applied physics have provided it. Specifically, a process called radiometric dating allows scientists to determine the ages of objects, including the ages of rocks, ranging from thousands of years old to billions of years old to a marvelous degree of accuracy. This relies on a proven combination of basic mathematics and knowledge of the physical properties of different chemical elements.

Cloth wrappings from a mummified bull Samples taken from a pyramid in Dashur, Egypt. This date agrees with the age of the pyramid as estimated from historical records.
Isotope radiometric dating
More about isotope radiometric dating:
Many rocks and organisms contain radioactive isotopes, such as U and C These radioactive isotopes are unstable, isotope radiometric dating over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay.
Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principlesradiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the isotope radiometric dating of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Petrology Tulane University Prof. Stephen A. Nelson Radiometric Dating Prior to the best and most accepted age of the Earth was that proposed by Lord Kelvin based on the amount of time necessary for the Earth to cool to its present temperature from a completely liquid state.

"An investigation of film boiling heat transfer in saturated pools of liquid Freon 113, Normal Pentane, Cyclopentane, and Benzene was made. The fluids were boiled from copper, cylindrical heat transfer surfaces, 3 inches long, and 0.55, 0.75, and 1.00 inch in diameter. The heat transfer elements were positioned horizontally in an autoclave and tested at moderate pressures of up to a pressure of 242.5 psia for Normal Pentane.
The experimental data are discussed and compared with known film boiling correlations. The known correlations were found to be inadequate in predicting heat transfer coefficients as a function of pressure, temperature difference between the heater surface and the fluid, surface diameter, and the type of fluid boiled. For instance, a correlation by Sciance predicts the experimental heat transfer coefficients, h, of this investigation from within 3% error to as much as 50% error. A correlation by Chang predicts values of h that vary by a factor of 3 from the experimental values of this investigation. The h values predicted by the correlations of Baumeister, Breen and Westwater, Pomerantz, Bromley, and Berenson deviate from the experimental values by percentages between those of the Sciance and Chang correlations depending on the pressure of the system, diameter of the heater surface, and the fluid under investigation.

One of the more fun things about being a flavor researcher is that you can whip up a batch of Hurricanes on the clock. That’s exactly what International Flavors & Fragrances research fellow Neil Da Costa did at the annual meeting of the American Chemical Society on Tuesday. Da Costa and other researchers unpacked some of the chemical secrets of fine spirits at a symposium called “the Chemistry of the Bar.”
Hurricanes were an appropriate choice for the New Orleans meeting, given that the sweet pink concoction is a common sight among the tourists that flock to the French Quarter.
The drink hails from the 1940s, when wartime conditions made scotch, bourbon and other whiskeys hard to find. Rum, however, was in abundance, and distributors were looking to unload it as quick as they could. Barkeeps might have to buy up to 50 cases of rum just to get one case of whiskey.
“One bar owner, Pat O'Brien, came up with the recipe for a fruity rum drink and served it in a glass shaped like a hurricane lamp,” Da Costa said in a statement. “The name stuck."
Drinking a Hurricane involves a complex bouquet of chemicals. You have the smoky phenolics that flavor rum, the citrals from lime juice that add a fresh note. From passion fruit, you get a sweet kind of compound called esters that is cut with a hint of sulfur. Though you might associate sulfur with rotten-egg smells, sulfur volatiles also contribute to the flavor of raw potatoes, Da Costa explained in a phone interview.
Since the Hurricane is such a sugary drink, Da Costa doesn’t recommend going for ones made with top-shelf rum; the quality liquor flavor is drowned by the other ingredients. He also doesn’t think much of grenadine, which provides a lot of sugar and red coloring, but not much flavor.
“It might be better to just get some pomegranate juice,” Da Costa said.
Cocktail science wasn’t the only kind of research on tap. University of Illinois researcher Elizabeth R. Genthner provided some historical perspective on the science of oak wood aging and alcohol spirits. One of the more important kinds of chemical compounds contributed by oak wood barrels are the so-called “whiskey lactones,” which give off a coconut-like scent.
Some scientists specialize in the aftermath of alcohol. University of California, Davis, researcher Alyson Mitchell said at the ACS meeting that an old New Orleans hangover cure called Yak-a-mein Soup, or “Old Sober,” might actually help ease the pain.
"Hangovers have been called a 'metabolic storm,’” Mitchell said in a statement. "They result from high blood levels of ethanol and the accompanying dehydration, direct toxic effects of the body's breakdown of alcohol into acetaldehyde and toxic effects of substances called congeners that are present in darkly colored liquor like scotch and bourbon."
Yak-a-mein, supposedly brought back to New Orleans in the 1950s by U.S. soldiers stationed in Korea, is usually made with beef and soy sauce broth, and contains noodles, meat, onions and sliced hard-boiled egg. Many of these ingredients, Mitchell says, can help clear the body of the chemical consequences of a hard night of partying.
The cysteine in eggs is thought to help clear out acetaldehyde, while the salts in broth replace what you’ve lost thanks to the diuretic effects of drinking (similar to how a sports drink replaces the electrolytes an athlete loses in sweating).
A hangover cure like yak-a-mein “may be a good example of intuitive science -- an effective remedy, and with the scientific basis revealed only years later," Mitchell said. | Yes |

Why we love this product
In the Pacific Ocean there is a mass of plastic garbage that is twice the size of France. And that’s because people throw 10 million tons of plastic garbage into the ocean every year. And it’s more than just a thorn in the side: fish eat the plastic waste, we eat these fish and human health is eventuall harmed. Disposable plastic packaging for daily use products – such as liquid household products – accounted for 54% of classic plastic waste in 2015. Our learned addiction to plastic-powered comfort harms our bodies and our planet. But how can you and we as a society produce less single-use packaging waste? This is where we come in.

In the UK the brewing and distilling sectors support thousands of jobs in production and engineering.
The brewing process is a bio-chemical one, in which malted barley and other cereals are mixed with water, the extract boiled with hops, cooled and fermented with yeast. During the fermentation process sugars form alcohol and carbon dioxide. The same process to extract sugars from malted barley is used in distilling, but the sugar solution is fermented without the addition of hops and without boiling. After fermentation the beer is matured and then packaged in a range of containers including casks, kegs, bottles and cans.While draught cask beer is much favoured by traditional ale consumers it has a relatively short life and needs close attention in the pub cellar. In contrast, beer packaged into bottles, cans and kegs is very stable and can be stored for some time.
In distilling, after fermentation the product is distilled and then stored and matured in oak barrels.
To brew and distil on the scale required and to maintain the consistent high quality demanded in the thousands of pubs, bars, clubs and retail outlets, the talents of skilled brewers, distillers and
engineers are essential. The brewing and distilling production sectors provide a huge range of opportunities across a wide range of skills and competences.
Brewers and distillers have a number of routes to commence and develop a career. A solid background in Science, Technical and Engineering secondary education is required. There are now apprentice opportunities as well as openings for those wanting to join after A-levels and also for those intending to enter after taking a relevant degree.
The sectors require a mix of employees with skills covering botany, bio chemistry, electrical engineering, mechanical engineering, chemical engineering, IT and other disciplines. There are also many more general career opportunities in the brewing and distilling business, where technical experience can be of real value. These will be found in distribution, sales and marketing, and IT.
Brewing and distilling are practised around the world and it is worth remembering that similar career opportunities can frequently be found for those prepared to work overseas. Similarly the distilling industry offers careers in a parallel discipline.

Transitioning analytical instrumentation from the laboratory to
R. B. Turner
Smiths Detection, 459 Park Avenue, Bushey, Watford,
Hertfordshire, WD23 2BW, UK
The development of sensitive analytical instrumentation for autonomous
operation in harsh environments is a difficult and expensive process.
The management of risk in this process is aided by the use of technology
readiness levels (TRLs) and awareness that the exponential growth of
costs through development militates very strongly against progressing
the development prematurely. It is also essential to have a very clear
view of the intended outcome at the earliest possible stage and to test
the systems in realistic environments as soon and as often as possible.
Economic production of large quantities of instruments requires considerable
attention to the details of the production process and the control of
materials; there is a constant battle against contamination. Future
instrumentation might involve a combination of analytical techniques,
but the desire for more selectivity and sensitivity must be balanced
against cost, complexity, and reliability.

Distilled water is a water which is free of germs, bacteria as well as essential minerals. Distilled drinking water is lacking in important minerals and therefore doesn’t follow the mandatory functioning of water. Water flushes away any pollutants from inside and so does distilled water soda water info. Nevertheless, distilled drinking water leaves no minerals behind for any growth of the body. Distilled drinking water will work for detoxification but usually it offers absolutely no beneficial outcomes for your overall body.
Water is heated to boiling level to ensure that harmful particles get segregated as well as water turns into water vapor. Later the same vapor condenses into water. Distilled water is actually tasteless and possesses no vitamins and minerals as normal water truly does. Our own bodies requires about SEVENTY FIVE percent of water for it to function well. Hence, you shall constantly hear physicians stating that you must drink a minimum of Six to eight glasses of drinking water every day. Insufficient water can result in dehydration and dryness of your skin area.
Since distilled water is completely free of any solids as well as minerals, it can easily rob your system of essential minerals. Drinking water should be able to provide you with excellent level of minerals and calcium rather than take these away from your body. Although its great to enjoy pure water, one can not eliminate the essential minerals. Unless you need to thoroughly clean your body for detoxing, it is advisable to avoid drinking distilled water.
Distilled drinking water is frequently given to dogs as well as domestic pets, however they as well need the essential vitamins and minerals and one can give them regular or filtered drinking water. Being addicted to distilled water additionally puts one on higher danger associated with a number of illnesses. People are surprised to understand that distilled water can boost health related risks substantially. Distilled water also leaches sodium, potassium, as well as chloride, and also absence of the same in the body can result in heart related illnesses and higher blood pressure.
Additionally it is claimed that distilled drinking water when exposed to air, can instantly soak up carbon dioxide from the air. This can make the water acidic resulting in acidity problems. Because of excessive loss in calcium one can possibly also suffer from weak bones. Some other outcomes of drinking distilled drinking water are premature ageing, artery diseases as well as digestive system complications. This kind of drinking water does not have any nutritional value and is thus not required by the body.
For quite some time specialists as well as doctors are actually explaining that accumulation of acids as well as waste inside body leads to premature aging and diseases. Incorrect diet and also health practices are certain to be blamed for illnesses and health problems, however distilled drinking water could contribute to these types of troubles. One should try and avoid this kind of drinking water unless advised by way of the doctors.
Drinking distilled water for very long periods leads to an acidic state of the human body. Additionally, it causes upset stomach as well as disrupts your whole body check this. Aside from detoxifying, distilled water should not be employed. Human body really does demand correct level of minerals as well as nutrition coming from food in addition to water. Keep away from distilled water as far as possible. Drink it only if you have a genuine need. There are actually much more damaging effects than benefits of consuming distilled water, therefore it is not recommended on a daily basis. | Yes |

Cannabis has been a growing problem around the world, with two main components found in the plant Cannabis sativa: cannabidiol (CBD) and tetrahydrocannabinol (THC). CBD has several positive effects on the human body, such as reducing neuroinflammation and brain damage caused by neurodegenerative diseases, which promotes the production of new neurons in the brain and increases levels of synaptic plasticity. However, CBD also has some negative effects such as irritability, extreme tiredness and nausea. Previous studies have suggested that CBD may improve the memory of people over 65 years of age with neurodegenerative diseases.
But what about people under 25? Is there any evidence that hemp can help with memory? The answer is yes! A recent study found that CBD may support memory function and reduce memory impairment by helping to increase the connection between brain cells. These results have been validated by clinical trials and research from other laboratories. Hemp gummies and CBD gummies may look the same, but they're actually completely different. Hemp-derived CBD products are classified as supplements, so it's important to pay attention to the quality of your CBD oil.
CBD is a cannabinoid, a chemical found naturally in cannabis plants, marijuana and hemp. It's important to note that CBD does not alter the mind like THC does. So if you're looking for a natural way to improve your memory, hemp-derived CBD products may be worth considering. Just make sure to do your research and buy from a reputable source. | Yes |

1. Apply ALKAATUFF DETERGENT - LIQUID with a H.P. cleaning machine and use 1:4 with water. If used by hand spray, apply neat on the surface @ 1 ltr per 12m2.
2. Leave for about 30 – 45 minutes. The surface remains wet.
3. Wash down with hot water at around 800 C. Repeat procedure 1 to 3, if required.
Cargo tank and Cargo hold cleaning
ALKAATUFF DETERGENT LIQUID can be used for tank cleaning after animal, vegetable and fish oil, petroleum waxes, and for cargo hold cleaning after soot, coal, pet coke and other bulk materials using the following methods -
• Direct injection method with tank washing machines: Dosage rate 10-15 lts. per 1000 liters wash water (1-5%).
• Recirculation method: Use dosage rate of 20-50 liters per 1000 liter wash water.
• Spot Cleaning: Hand spray neat or prepare a 10-20 % solution. Leave for approx. 30 minutes before rinsing with water. Keep surface wet.
Before cleaning with ALKAATUFF DETERGENT is recommended to pre-wash cargo tanks with hot water 50-60 0C.
For Drying oils and semi- drying oils a prewash of the tanks with cold water should be applied.
The efficient operating temperature varies and is depending upon the type of cargo residues which are to be cleaned. In cases like Palm oil residues the optimal solution temperature is between 55-65 0C at the tank cleaning machine nozzle. Higher temperature tends to bake on the residues rather than removing them.
Hydrogenated oils contain stearic acid with melting point of approx. 70 0C. to clean such cargo residues successfully, a temperature between 72-77 0C at the tank cleaning machine nozzle must be used.

ALKAATUFF DETERGENT LIQUID - HD (RXSOL-22-3030-25)
The Importance of ALKAATUFF DETERGENT by High-Pressure Cleaning
The job of high pressure cleaning can be done easier & quicker by simply using ALKAATUFF DETERGENT in correct dosages. Using a high pressure cleaner alone, without any CLEANER, will not achieve optimal cleaning results High-pressure cleaning primarily refers to cleaning of Hard surfaces, such as Decks, Tanks, Engine-rooms, etc. and in the majority of cases the cleaning is done according to the so-called two-step method:
Step 1: Spraying the ALKAATUFF DETERGENT over the area to be cleaned.
Step 2: Washing down the area using a high-pressure water jet.
After the ALKAATUFF DETERGENT has been sprayed on the surface and before the wash down begins, the chemicals penetrates & thoroughly moistens dirt & other grime. During wash down, the ALKAATUFF DETERGENT thoroughly dissolv- es the particles of dirt, even oil and fat, in the water spray and thus achieves optimal cleaning results.In addition to being more effective, the use of RxTuff substantially reduces the time required for the Cle -aning operation, as well as preventing dirt from reforming on the surface. The use of RxTuff in correct dosages is half the job done.
3 Pieces of Good Advice:
Apply ALKAATUFF DETERGENT on dry surface where possible! A dry surface will absorb far better than a wet surface. When applying RxTuff on vertical surfaces: Start application from the bottom and work upwards! If beginning from the top and going downwards, the ALKAATUFF DETERGENT may produce "channels" down the surface, thereby running too fast off the surface. During high pressure cleaning: It is important that the rinsing water does not run over non-cleaned surfaces! The rinsing water can draw soap from the surface if running over non-cleaned surfaces. High pressure together with optimum concentration of ALKAATUFF DETERGENT will give the best effect .
Product Description:-ALKAATUFF DETERGENT is a superior & powerful alkaline cleaner containing corrosion inhibitors to prevents the corrosion of metals . It is low toxic product with an exceptional solvency power on soil & oily matter & having good foaming qualities. It is free from Hydrocarbon solvents , Biodegradable and minimizes the extreme hazards to personnel in handling materials .
Applications:-ALKAATUFF DETERGENT Suitable for cleaning engine components like fuel and Lube oil filters, Injection nozzles, pump components, inlet and exhaust valves & primarily refers to cleaning of hard surfaces, such as Decks, Tanks, Engine-rooms, etc. can be used for all types of cleaning and degreasing and may be applied by brush, handspray, high and low pressure washing machines etc.
Directions for Use and Dose Rates:
General Cleaning:- ALKAATUFF DETERGENT can be used for all types of cleaning & degreasing & may be applied by Brush, Hand spray, high and low pressure washing machines etc. Time necessary for cleaning depends on the nature and thickness of the deposits. 20-30 min. will suffice for most applications. Hardened, carbonised or aged deposits may require up to 4 hours. If the cleaning solution is not heavily contaminated, it may be re-used at a later stage. If allowed to cool, the de-gassing procedure must be repeated. Depending on degree of contamination ALKAATUFF DETERGENT should be mixed with warm water at a rate of 50-200 ml per 10 litres. i.e. 1 cup of ALKAATUFF DETERGENT to a bucket of water. ALKAATUFF DETERGENT solution can be applied simply by mops, brushes or rags, or by dipping the soiled articles into the ALKAATUFF DETERGENT solution. After cleaning, rinse off with cold or warm water. Due to high foaming properties, ALKAATUFF DETERGENT is not recommended for washing machines.
• Ideal for cleaning after coal and pet coke. Tank Cleaning:-Cargo tank cleaning to remove residues of Mineral, Animal, Vegetable or Fish oil, Waxes & Soot from inert gas systems.
Method of Application and Dose Rates:-
- Direct injection method for tank washing machines. Dose rate 1-5 litres per ton wash water (0.1-0.5%).
- Recirculation method. Dose rate 1-7 litres per ton wash water (0.1-0.7%).
- Spot cleaning. Hand spray neat or diluted with up to 5 parts water and leave for several minutes before rinsing off with clean water.
Cleaning of Cargo Tanks to Remove Soot from Inert Gas Systems:-
- Spray ALKAATUFF DETERGENT on with a high pressure cleaning machine and use 1:6 with water. If used with hand sprayer, spray the product neat onto the surface, allowing 1 lit. for every 12 m2. Use a 5-8% solution in a tank washing machine.
- Leave for about 30-45 minutes. The surface should be kept wet.
- Wash down with hot water (80°C) and check the cargo tank.
- Repeat the procedure if necessary.
Note:- Whenever possible, the cleaning solution should be heated to 60-80°C.If this method is not possible, other conventional methods such as separate rate direct injection, recirulation or hand spraying provide acceptable options.For boiler fire side cleaning, a 10-20 % hot solution, (temp. above 40°C), should be sprayed on to the surfaces to be cleaned. Allow to penetrate for 20 minutes and flush off. For deposits which are very hard to remove, increase the concentration to 50% and repeat if necessary.
ALKAATUFF DETERGENT most suitable for cargo hold and tank cleaning.
ALKAATUFF DETERGENT High foam plays very important role during ship hold cleaning, Its high foam ability increasing ALKAATUFF cleaning power on the vertical surface, As liquid product can't sustain on the vertical surface while HIGH composite FOAM can sustain on the surface which is resulting from good cleaning effect.
Extra foaming is major features which is differentiating ALKAATUFF high foam to general ALKAATUFF.
ALKAATUFF High foam using procedure and cleaning method :
1st Step Cleaning of extra and excess loose particle:::
Before applying ALKAATUFF DETERGENT high foam on hold surface, Makes sure extra loose cargo particle should be removed manually or Air blown method. Then cleaning procedure can be followed either by high foam machine or Manual.
2nd step is for Mixing and dilution of ALKAATUFF DETERGENT:::
If cleaning step is with HP machine ( High Pressure ), Then mix concentrated ALKAATUFF high foam with fresh water, it can be diluted 1 Ltrs ALKAATUFF High foam with 4 to 5 Ltrs Fresh water.
If cleaning step followed by hand spray, Then apply ALKAATUFF DETERGENT high foam neat on the surface. Approx 1 ltr covers 10 to 12 square meter.
3rd Step final procedure:::
Leave for about 30 – 45 minutes. The surface remains wet. Wash down with hot water at around 80 - 90 degree. Rinsing procedure can be repeated 1 to 3 times if required for Cargo Tank and Cargo Hold Cleaning.
Why should we avoid SEA WATER during Ship Hold Cleaning?
The hardness of Seawater reducing Foaming Qualities of ALKAATUFF.
Seawater also reducing the foaming qualities of the any detergent.
As per chemistry law and detergency effect sea water reducing cleaning effect.
Seawater increasing corrosion risk to the surfaces and the equipment used and metal surface.
When mixing ALKAATUFF with seawater Higher concentration of ALKAATUFF required at least 20 - 25% (ratio 2:9 to 1-3).

Capillary Pressure Measurements for CO2, Brine and Berea Sandstone at Reservoir Conditions
MetadataShow full item record
Technically, we conducted a capillary pressure experiment using the methodology suggested by Pini et al. (2012): we injected scCO2 into a sandstone plug which was fully saturated with CO2-saturated brine. This method assumes that the applied viscous pressures are equal to the capillary pressures. Initially a low CO2 injection rate was applied and once steady-state was reached the injection pressure and the brine saturation in the plug were measured. In our case, the brine saturation in the plug was measured by volume balance, the volume of produced brine was measured in a separate ISCO pump. This process was then repeated at incrementally increasing CO2 flow rates and the capillary pressures at different water saturations were measured (again at steady-state conditions).

The ancient Greeks believed in the spontaneous generation of life. More recently, Louis Pasteur showed that life did not arise from non-living material. Yet those who deny the Creator's existence must believe it happened once upon a time. Evolutionists estimate the earth to be 4.6 billion years old and the earliest fossils about 3.8 billion years old. An initially hot Earth might take, say, 0.3 billion years to become "user friendly," so the first life took only about half a billion years to arrive from abiotic (non-living) starting materials. If it is as easy as just having the right conditions, one might think that life should have evolved many times before the advent of photosynthesis produced an oxygen concentration which made conditions unfavorable. Yet all life rides upon the same biomolecules, metabolic pathways, and genetic information, so life had but one origin, either created or evolved.
Modern theories of the origin of life date back to the Soviet scientist Oparin in 1924. His ideas of a Primeval Soup were promoted in the West by fellow communist J.D.S. Haldane of Cambridge. In 1953 Urey & Miller published results of some simple experiments in organic chemistry which seemed to lend credence to the soup theory. Interestingly, forty years later, Miller admitted that the question of the origin of life is much more difficult than he, or anyone else, had thought. Clutching at straws, others have suggested mid-ocean ridges (with their cocktail of hot chemicals) as the cradle of life, while others have postulated an extraterrestrial seeding of the Earth. This latter suggestion still does not offer a mechanism for abiogenesis.
With the development of molecular biology since the time of Oparin and Haldane, the cell is no longer regarded as simple. The living plasma membrane allows in or out only specific compounds. It is not simply a semi-permeable membrane. Cells contain nucleic acids that carry information about the structure and functions of the organism. They also contain ribosomes where proteins are made using a complex mechanism of nucleic acids and more than a hundred different proteins, each with a specific task. The cell also contains mitochondria where energy (ATP) is produced. The complexity of all these parts of the cell is enormous. Lynn Margulis has suggested that the first proto-cell assimilated these organelles by a process of symbiosis. However, these components cannot now exist independently, nor could the cell exist without their contributions. Moreover, one such type of organelle, known as a lysosome, contains enzymes whose function is to digest foreign bodies. With all the amazingly complex, mutually-dependent components, it seems that the cell had to be complete from the beginning, rather than being assembled piecemeal over years of evolution.
The major biochemicals in living cells are proteins and nucleic acids. No biologically significant proteins or nucleic acids have been made by any experiments such as those of Miller or those who have followed him.
Proteins are strings of amino acids whose enzymatic activities arise from active groups within a specific three-dimensional shape. These are due to a precise sequence of the amino acids. There are twenty amino acids found in proteins, although many others exist that are not used in metabolic pathways. Chemically they are NH2CH(R)COOH, where R is H in the simplest case, glycine, but can also be a variety of organic groups such as CH3 in alanine. In all amino acids except glycine, the central carbon is surrounded by a tetrahedron of four different groups, H, R, amine and carboxylic acid. Because of this asymmetry, amino acids exist in two forms, designated right- and left-handed (or d and l, or R and S). In proteins (a string of amino acids—NHCH(R)CONHCH(R¢)CO&mda
In laboratory experiments aimed at simulating conditions on a lifeless Earth, a messy mixture of amino acids can be formed, consisting of mostly glycine and d/l-alanine. Not all amino acids found in proteins can be synthesized in this manner, while many not used by living systems do result from these experiments. A product consisting of exclusively left-handed amino acids never results, and from theoretical considerations cannot result. Only d/l racemic mixtures are formed. Peptization, the joining of the amino acids to form a protein by the elimination of water, is difficult to accomplish by non-biological means. Proteinoids are unstable in the presence of water. Since they cannot replicate themselves, natural selection cannot be a driving force in their improvement. The precise order of amino acids in proteins in cells is governed by information on the nucleic acids that code for them, so this could not be achieved by chance. Moreover, the tar-like by-products would tend to poison any enzymatic activity in proteins.
Nucleic acids are found in living cells as DNA, ribosomal-RNA, messenger-RNA and transfer-RNA, each with specific properties. They consist of strings of nucleotides, which are composed of a nitrogenous base, a sugar and a phosphate linkage. DNA carries the genetic information for the organism while RNA is used in protein synthesis. There are four different bases on the double-stranded DNA. The strands are linked by weak hydrogen bonds between bases on each strand. The structure of the bases is such that each in one strand only links with one other type of base in the other strand. One single strand of DNA therefore acts as a template for the other strand during cell replication. Three consecutive bases act as a codon to transfer information to specify a particular amino acid, or to start or stop a sequence. This information on a string of DNA (gene) is responsible for the formation of a particular protein. Since there are four bases, there are sixty-four codons (43), which pass information rather like the letters and punctuation of a written message. This is a precise mechanism. Information transfer is checked at a rapid rate by proteins for random changes, known as mutations, which lose information. No mutation could lead to an increase of information, so neo-Darwinism cannot be a mechanism for macroevolution. It is a tenet of Information Theory that information only comes from an intelligent source, so genetic information must have been created. Information not only implies meaning, but purpose. This is the opposite of chance. As a carrier of information the DNA molecule is 4.5x1013 (45 trillion) times more efficient than the silicon megachip, which was made by teams of designers. Incidentally, a stereo-chemical basis for the relationship between any particular three nucleotides and the amino acid for which they code has not yet been elucidated.
When nucleotides are joined in the laboratory, thermodynamic considerations allow one particular site for bonding phosphate to sugar to the next phosphate. However, such a pseudo-DNA strand is not biologically useful. The bonding site found in DNA, the 3¢ and 5¢ carbons of ribose, is in the best position because the proteins used to join it together act as templates to get the junction across the sugar right. The sugars, deoxyribose in DNA, and ribose in RNA, are also chiral like the amino acids, but in this case the sugars are all right-handed. Again, there is no conceivable mechanism for arranging this by chance.
Urey and Miller had to assume, contrary to the opinions of geologists, that the early Earth had no oxygen in its atmosphere. This is because amino acids are destroyed by oxygen. But absence of oxygen implies absence of ozone, another form of oxygen. Ozone in our atmosphere protects us from high energy ultra-violet rays from the Sun. Nucleic acids are rapidly decomposed by UV light. A further difficulty for those who postulate abiogenic synthesis is that the molecules formed are destroyed by the very conditions (such as heat, UV light and electricity) that make them. Proteins and polynucleotides are thermodynamically unstable. They are also unstable with regard to hydrolysis and reactions with other simple reagents. Moreover, the longer the experiment is allowed to continue, the more decomposition products are made. Many processes are reversible, and in the equilibrium state simpler starting materials predominate over more complex products. Time does not help the forward reaction. The tarry messes from these experiments are in stark contrast to the neat metabolic pathways of living cells with their clean, high yields of precisely fashioned products. In their experiments to simulate abiogenic development, investigators begin each stage with pure compounds in high concentrations. This can hardly reflect natural conditions on a prebiotic Earth.
In the living cell, the DNA codes for proteins and the DNA is itself constructed using proteins. It is a chicken and egg situation. It has been suggested that RNA possesses some of the enzymatic properties of proteins while having the information carrying ability of DNA. Could positing a first proto-cell that relied on RNA for both functions, solve the problem? No primeval soup experiment has ever produced anything resembling RNA. RNA does not replicate itself, a prime necessity for a living cell. RNA's enzymatic properties are not sufficiently versatile for even the simplest imaginable proto-cell. The problem of the origin of information on the information carrying RNA remains unsolved. A proto-cell based solely on proteins is equally impossible, since proteins lack the ability to reproduce themselves.
Each component of a living cell is breathtakingly complex, yet in isolation it cannot survive nor replicate itself. All the parts of the cell are necessary to its functioning and replication. Nothing works until everything works. This has been called irreducible complexity. Even small parts of the components of cells can be unimaginably complex. An example of this is the enzyme adenosine triphosphate synthase, found in all living cells including animals, plants, fungi and bacteria. The elucidation of the structure of ATP synthase won a 1997 Nobel Prize. Every cell contains hundreds of these miniature motors embedded in the surfaces of the mitochondria. Each is 200,000 times smaller than a pinhead. The motor forges a bond between ADP and phosphate to form ATP. The ATP couples with other processes in the cell requiring energy to reform ADP and phosphate. So energy is directed to contract muscles, beat the heart and drive thought processes in the brain, while the products are recycled. At the centre of ATP synthase is a tiny wheel that turns at about 100 revolutions per second and turns out three ATP molecules per rotation. Just to keep us thinking and walking, humans must recycle their own body weight of ATP each day. Each enzyme is composed of thirty-one separate proteins that in turn are made of thousands of precisely arranged amino acids. Take away any one of the 31 proteins and the motor is useless. It could not have evolved. And consider this: the genetic information and RNA plus proteins needed to construct the ATP synthase are in total even more irreducibly complex than the ATP synthase itself. (A car-making factory is more complex than a car.)
The concept of abiogenesis is vital to the atheistic evolutionist. It follows in their thinking that if life can arise spontaneously under the right conditions, then there will be perhaps millions of planets in the Universe where life already exists. In some of these places intelligent life may have evolved. These ideas have spawned a large body of literature, films and video games involving imaginary extraterrestrial life. Billions of dollars have been spent by government sponsored searches for messages from out there (e.g., project SETI). The irony is that evolutionists would recognize that a nonrandom signal from space that carried information with meaning and purpose must have come from an intelligent extraterrestrial. Yet they consider nucleic acids in the living cell, a nonrandom sequence of nucleotides carrying far more information with precise meaning and exquisite purpose, and say it must have arrived by chance!

Facing the situation of acute respiratory infection caused by Corona virus and the scarcity of antibacterial hand sanitizer on the local market, An Giang University conducted a preparation of dry hand sanitizer to dispense for staff and students. This is a research product of the Department of Chemistry - Department of Pedagogy and Experimental Laboratory - Equipment Administration Department.
The ingredients of the dry hand cleanser include alcohol 70%, glycerin, gydrogen peroxide, itamin E and essential oils. Specially, the composition of essential oils is extracted from medicinal leaves by the University's teaching staff, which is both antibacterial and good for the respiratory tract. The manufacturing procedure is carried out in a laboratory with strict control over the use of ingredients and the stages of implementation.
According to Dr. Lam Thi My Linh - Head of the Department of Chemistry Department, this product would be able to disinfect up to 90% and create a moist layer to protect the skin thanks to the ingredients of Vitamin E and essential oils. The University is planning to produce 10,000 100-millilitre bottles and, based on the reality, will continue to produce to meet the needs of prevention and control of the Covid-19 virus in the near future.
In addition to producing hand sanitizers for teaching staff and students, the University also conducted disinfecting sprays in offices, classrooms, laboratories, dormitories and propagated disease prevention measures on the media.

Medicinal plants are of great significance and global importance as antioxidants and antibacterial agents. In the present investigation the chloroform leaf extract of Abelmoschus manihot was screened for its phytochemical constituents, antioxidant and antibacterial properties. Flavonoids, phenolics, tannins and vitamins were the phytochemical constituents present. GC-MS analysis revealed ten major phytocompounds. In vitro antioxidant assay via DPPH exhibited an IC50 value of 234.7±37.53mg/mL, and its activity could be ascribed due to the presence of the phytocompound a-tocopherol. The antimicrobial activity represented by the zone of inhibition via disc diffusion method, observed no activity against the fungal strains, Aspergillus niger and Candida albicans. Staphylococcus aureus and Escherichia coli exhibited 12 to 14mm zone of inhibition at concentrations 100-500µg, which can be attributed due to the presence of flavonoids. The above results suggests that antioxidant and antibacterial activity exhibited by the chloroform leaf extract of this plant was attributed to the presence of the phytochemicals, especially phenolics and flavonoids. Further in depth studies on the phytochemical constituents of this chloroform leaf extract is recommended, as this extract could serve as an additional implement to natural antioxidant and antibacterial agents.

3D Mixing Machine.
The barrel of the material is driven by the active shaft to make the compound motion of translation rotation and tumbling, etc. from week to week, which makes the material make the three-way compound motion along the barrel in the circumferential, radial and axial directions, thus realizing the mutual flow, diffusion, accumulation and admixture of various materials to achieve the purpose of uniform blending.
3D Mixer Performance Features
With multi-directional movement, materials without centrifugal force, no specific gravity deviation and stratification, accumulation phenomenon each group can have a disparity in weight ratio, mixing rate of 99% or more, mixing uniformity is higher than the uniformity of other ordinary mixers
The barrel loading rate is large, up to 80-90% (only 40% for the ordinary mixer), high efficiency, short mixing time. The cylinder body is rounded and polished in all parts.
3D Mixer Composition
The 3D swing mixer is composed of the machine base, drive system, three-dimensional movement mechanism, mixing cylinder and electrical control system, etc.
The mixing barrel in direct contact with the material is made of high-quality stainless steel, the inner wall of the barrel is polished and processed with precision.
3D Mixer Operation
1. This machine adopts frequency converter to regulate speed, before starting the machine, turn on the total power supply, the power indicator light is on, then start the motor button, then start the on/off switch on the speed control panel, the indicator light is on, then slowly rotate to make it reach the normal mixing speed;.

3D Mixer Cautions
The mixing of this machine is three-dimensional space mixing, adding some safety protection fences near the effective range of the material barrel, to avoid accidents. Before starting the machine, do not stand in front of the barrel to avoid accidents.
When loading and unloading, the electric of the equipment must be stopped to prevent electrical failure and cause unnecessary accidents.
Horizontal Ribbon Mixer.
Horizontal ribbon blender is to stir dry and powder materials evenly. The material in the mixing time is subject to the rotor movement in two opposite directions, and the compound movement, which causes convection circulation and shear percolation in the material barrel, and completes the rapid and uniform mixing of the material in a relatively short time.
Ribbon Mixer Performance Features
U-shaped barrel structure, smooth operation, uniform mixing, no dead angle, clean discharge, wide range of applications.
Adopt internal and external double-layer spiral belt staggered round-trip mixing, fast mixing speed, high uniformity

Ribbon Mixer Working Principle
The drive spindle of the mixer is arranged with a double layer of spiral blades, with the internal spiral conveying the material to the outside and the external spiral gathering the material to the inside.
The material is convected by the convection movement of the double-layer spiral ribbon, forming a low-power and efficient mixing environment.
The inner and outer diameter spirals installed on the mixing shaft drive the materials inside the barrel, so that the mixer turns the materials in the barrel to the maximum extent.
Ribbon Mixer Application
It is applied to the mixing of solid-solid (i.e. powder and powder), solid-pulp (i.e. powder and mastic liquid) of putty paste, real stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractory materials, etc. It is especially adapted to the mixing of viscous materials.
This mixer is not suitable for the mixing of materials with large fiber content and large density difference.
It is recommended to use stainless steel for putty paste, real stone paint, biological, pharmaceutical and food industries.
In general, mixing dry mortar material containing glass beads, horizontal ribbon blender is highly recommended.
Ribbon Mixer Model selection
The following points need to be noted when selecting the model and options of ribbon blender.
1. Select the ribbon mixer according to the daily production volume. Because the mixer requires processing time for each batch of material, plus the time to discharge and feed.
2. Select horizontal mixer need to pay attention to the discharge mode. Communicate in advance and today’s machinery in time to choose a suitable form of valve for their own processes, while trying not to choose the side port discharge form. The reason is: First, the delay in time, not reach the expected productivity, the second is that the material has reached the best uniformity, excessive mixing will instead destroy the uniformity, lose the purpose of choosing ribbon mixer.
3. According to the material situation to choose the material grade of stainless steel, if the material is too corrosive, then you can choose a high grade stainless steel material or choose to lining corrosion-resistant layer.
Double Cone Mixer.
Double cone blender is by rotating barrel, using the material self-weight continuous turning for mixing. 360 degree rotation without dead angle, when the cylinder is rotating, the inside stirring leaves reverse operation, so that the material is quickly integrated.

|Born||26 December 1825
Freyburg an der Unstrut in the Province of Saxony
|Died||10 August 1895
Wasserburg am Bodensee
Hoppe-Seyler was born in Freyburg an der Unstrut in the Province of Saxony. He originally trained to be a physician in Halle and Leipzig, and received his medical doctorate from Berlin in 1851. Afterwards, he was an assistant to Rudolf Virchow at the Pathological Institute in Berlin. Hoppe-Seyler preferred scientific research to medicine, and later held positions in anatomy, applied chemistry, and physiological chemistry in Greifswald, Tübingen and Strasbourg. At Strasbourg, he was head of the department of biochemistry, the only such institution in Germany at the time.
He was one of the founders of biochemistry, physiological chemistry and molecular biology, and his work led to advances in organic chemistry by his students and by immunologist Paul Ehrlich. Among his students and collaborators were Friedrich Miescher (1844–1895) and Nobel laureate Albrecht Kossel (1853–1927).
His numerous investigations include studies of blood, hemoglobin, pus, bile, milk, and urine. Hoppe-Seyler was the first scientist to describe the optical absorption spectrum of the red blood pigment and its two distinctive absorption bands. He also recognized the binding of oxygen to erythrocytes as a function of hemoglobin, which in turn creates the compound oxyhemoglobin. Hoppe-Seyler was able to obtain hemoglobin in crystalline form, and confirmed that it contained iron.
Hoppe-Seyler performed studies of chlorophyll, and is credited with the isolation of several different proteins (which he called proteids). He was also the first to purify lecithin and establish its composition. In 1877 he founded the Zeitschrift für Physiologische Chemie (Journal for Physiological Chemistry), and was its editor until his death in 1895. He died in Wasserburg am Bodensee in the Kingdom of Bavaria.

Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. Some growers in the U.S. succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content. Hemp is classified as any part of the cannabis plant containing no more than 0.3% THC in dry weight form (not liquid or extracted form).
Knowing how much CBD you’re taking can take a little math. Again, capsules are straightforward—the bottle will say how much CBD each one contains. For tinctures, you need to know the total amount of CBD in the container and the container’s size to calculate how much CBD is in each serving. I found 1-ounce tincture bottles, which contain roughly 30 servings, that ranged from containing 100 milligrams of CBD to 1,000.
I have had several neurological conditions like Bells Palsy three times, double vision, paralysis of left side of tongue. I have a lot of relief whenever I have pain by taking an inflamattory drug etoshine90 mg. Presently I have started taking Steroids for my facial palsy. The various pains I was having on the left side of neck, below the left ear, dizziness, pain around the head have subsided immidiately after the first dose of prendisolone 60 mg.I have read that CBD hemp oil can be useful for my condition of neurological and inflammation issues. My question is what concentrate (mg) of the oil should I take and for how long. Any brand that you may suggest that are available in the UK. Thank you.
Further testing found what the world now knows: This compound is the plant’s principal active ingredient, its mind-altering essence—the stuff that makes you high. Mechoulam, along with a colleague, had discovered tetrahydrocannabinol (THC). He and his team also elucidated the chemical structure of cannabidiol (CBD), another key ingredient in marijuana, one that has many potential medical uses but no psychoactive effect on humans.
Can’t sleep? Cannabis oil also works for people with insomnia. The calming effects of the oil help people to sleep calmly, relieving issues of anxiety and restlessness. A 2015 scientific review published in the American Journal of Health-System Pharmacy found that cannabis treatment is effective for military veterans with posttraumatic stress disorder (PTSD). Research suggests that cannabinoids, the psychoactive components of unrefined cannabis, regulates neurotransmitter release and produces a wide range of central nervous system effects, including increased pleasure and alteration of memory processes.
Vaping, tinctures, topicals—they all have their qualities, but does anything beat the decadence and sheer enjoyment of dark chocolate? These Tasty Cocoas CBD Chocolates from Tasty Hemp Oil come individually wrapped, ready to deliver a delicious serving of soothing CBD. Made with the highest-quality cocoa and raw hemp oil, these chocolates are available in dark and dark mint variations.

Assay Development: Fundamentals and Practices
Essential principles and practice of assay development
The first comprehensive, integrated treatment of the subject, Assay Development: Fundamentals and Practices covers the essentials and techniques involved in carrying out an assay project in either a biotechnology/drug discovery setting or a platform setting.
Rather than attempting comprehensive coverage of all assay development technologies, the book introduces the most widely used assay development technologies and illustrates the art of assay development through a few commonly encountered biological targets in assay development (e.g., proteases, kinases, ion channels, and G protein-coupled receptors). Just enough biological background for these biological targets is provided so that the reader can follow the logics of assay development. Chapters discuss:
The basics of assay development, including foundational concepts and applications
Commonly used instrumental methods for both biochemical assays and cell-based assays
Assay strategies for protein binding and enzymatic activity
An in-depth study of the now popular Caliper's off-chip kinase assay provides an instructive, real-world example of the assay development process.

Williams announced a direct investment in Aurora Hydrogen, a company developing technology that converts natural gas to hydrogen with zero carbon dioxide (CO2) emissions.
Aurora Hydrogen’s technology uses microwave energy to convert methane to hydrogen and solid carbon without generating CO2. Williams’ investment will support scaling production to 200 kg of hydrogen per day, with the development of a demonstration plant by 2023. Williams was joined by Energy Innovation Capital (EIC), Chevron Technology Ventures, Shell Ventures and the George Kaiser Family Foundation in the investment in Aurora Hydrogen.
“The Aurora Hydrogen technology supports our strategy to further leverage natural gas as a powerful tool in decarbonizing the energy value chain,” said Chad Zamarin, senior vice president of Corporate Strategic Development for Williams. “With our existing energy infrastructure, Williams is well positioned to transport, store and deliver next generation natural gas and accelerate the development of zero carbon energy sources including hydrogen and renewables. The investment in Aurora Hydrogen further demonstrates our commitment to develop solutions that continue to meet growing energy needs while helping customers achieve sustainability goals.”
Hydrogen production from the Aurora technology has the potential to reduce global CO2 emissions significantly while using less electricity than other methods of hydrogen production and avoiding the need for CO2 sequestration. Additionally, the process does not require water as a feedstock, preserving another critical resource.
Williams made its investment through its Corporate Venture Capital (CVC) program, which is intended to support efforts to commercialize emerging technologies including clean hydrogen, solar, carbon capture utilization and storage (CCUS) and next generation natural gas.
Through the CVC, Williams has also committed approximately $40 million toward venture funds and direct investment in emerging technology companies at the forefront of energy transition. This includes a recently funded partnership with Context Labs to offer differentiated services to customers across the natural gas value chain. The initiative will overlay advanced sensors, satellite monitoring and blockchain technology to provide end-to-end measured, verifiable and transparent emissions data for real-time decision-making.

Purely Sheaź was developed by a pharmacist who suffered from severe skin rashes as a result of using harsh hand cleansers in a hospital pharmacy. Countless products were used to help the condition, including refined shea buter, but nothing seemed to help. A family friend suggested the use of Pure Unrefined Shea Butter instead to provide relief. And then something amazing happened-3 days later the rash was gone. The pharmacist was in awe and wondered why the previous refined shea butter did not work like the Pure Unrefined Shea Butter did. After much intensive research, it was learned that ALL SHEA BUTTER PRODUCTS ARE NOT EQUAL! In fact, most commercially available shea butter products lack the vital healing factors needed to provide true therapeutic benefits. This is because they are chemically extracted using dangerous petroleum by-products (hexane), and dangerously refined by bleaching, neutralizing with toxic lye, and extreme over-heating. Purely Sheaź was created to tell the true story of shea butter. 100 % Pure Unrefined Certified Organic Shea Butter that is unprocessed, naturally extracted, as well as fairly traded is the foundation of this powerful healing and therapeutic skincare system.

In FDM printing, the moisture present in the filament plays a big role in whether a part is printed successfully or not. In this series of articles we will explain the interaction between moisture and 3D printing, as well as how to counteract and prevent moisture absorption.
The first article will be discussing how plastics react to moisture, and what effects this has on their properties.
What is moisture?
The word moisture describes the presence of slight-to-moderate amount of liquid, most commonly water, as a vapor, within a solid or condensed on a surface. When it comes to defining the moisture in the air, we talk about humidity. The moisture or humidity of an environment describes the amount of water vapor in the environment’s air. Depending on the situation, moisture could either be detrimental or beneficial. For instance, it is good to have a humid environment in a greenhouse, but humidity could be dangerous in old houses with mould issues.
Humidity may sometimes present itself as condensation on a cold window
Different polymers and moisture
There are various polymers that are used for 3D printing, and they all react to moisture differently. Some are very hygroscopic, and will readily absorb moisture from the air, while some are less hygroscopic and will not absorb as much moisture. This section will briefly discuss some polymers and their affinity to moisture.
Nylon materials are among the most used engineering thermoplastics in the 3D printing industry due to their high versatility. Nylons typically have high strength, good chemical resistance and good fatigue resistance.
Nylon parts used for chemical resistant parts
All nylons are hygroscopic, and this property plays an important role during 3D Printing. The rate of moisture absorption in nylons depends heavily on the the ambient temperature and relative humidity. As a general rule, materials tend to absorb more moisture when the environmental humidity is higher. The level of moisture in nylons will have an impact on the material’s properties. The absorbed water molecules act as a plasticizer in nylons. This means that it will alter some mechanical properties, such as yield strength, tensile modulus and glass transition temperature.
For more information about Nylons and how to print them, check out this blog post all about Nylons.
Acrylonitrile butadiene styrene (ABS)
ABS is a commonly used thermoplastic which is used in various industries. As a material, ABS has a high durability, which plays an important part in the design of parts made from this material. Unlike Nylons, ABS does not absorb moisture as readily, and absorption is very slow at room temperature. That being said, the rate of absorption is still dependent on the humidity and temperature of the environment.
ABS, used for Lego Blocks
As the absorbed moisture in ABS increases, the tensile properties of the material decrease linearly. The extent of this decrease, as well as which properties actually decrease depends a lot on the fabrication process. ABS parts created through injection molding will have different properties than an ABS part created through 3D printing.
Polycarbonates are engineering thermoplastics that are transparent by nature and amorphous. They are used extensively in engineering industries due to their versatility when it comes to mechanical properties and recyclability.
Polycarbonates are used for coloured transparent roofing
Although polycarbonates are not as hygroscopic as nylons, moisture absorption still severely affects the way that they are processed, especially when exposed to high humidity and temperature. Exposure to prolonged humidity also puts the material through a ductile-to-brittle transition. Moreover, moisture absorption lowers the tensile properties of polycarbonates, allowing for more crack growth and propagation to the fracture surface. This presents itself as a decrease in tensile strength of the material itself.
For more information about PC and how to print it, check out one of our earlier blog posts all about PC.
Moisture and 3D Printing
We have seen that polymers that have absorbed moisture have some of their properties deteriorate. When it comes to 3D printing, this deterioration of properties has a negative reaction on the final product. Each material has its own issues when it comes to 3D printing, and in the upcoming blogs in this series we will be delving into these issues. We will be discussing moisture and 3D printing, as well as how to counteract and remove moisture from filaments. Stay tuned! | Yes |

Hopefully, these questions will address your most pressing concerns, but if you still need help, don’t hesitate to reach out to our specialists.
01. Hard Water Questions
There are several signs that can indicate whether your water is hard or not. One of the most common signs is soap scum, a white substance commonly found on surfaces like sinks and bathtubs. Hard water can also cause faucets and showerheads to become clogged with mineral deposits, and it can leave stains on clothes and dishes. You may also notice a decrease in the effectiveness of your detergents and soaps as they struggle to lather in hard water. If you’re unsure whether your water is hard, you can purchase a test kit, contact your local water utility for more information, or schedule water testing services with Serv-All Water Conditioning.
Water is considered hard if it contains high levels of dissolved minerals like calcium, magnesium, and manganese. The hardness of water is typically measured in grains per gallon (GPG) or parts per million (ppm). Here’s a breakdown of the different levels of water hardness:
- Treated (or softened water) = 0
- Slightly hard = 1-2 grains per gallon (total grains x 17.1 equals ppm)
- Medium Hard = 3-7 grains per gallon (total grains x 17.1 equals ppm)
- Hard = 7-10.5 grains per gallon (total grains x 17.1 equals ppm)
- Extremely Hard Water = 10.5+ grains per gallon (total grains x 17.1 equals ppm)
Note: Each ppm of iron equals 4 grains per gallon of hardness.
Remember, the higher the levels of dissolved minerals, the harder the water is considered to be. We hope this page helped you understand how to determine your hardness. If you still have questions regarding hard water, please email us or call us anytime.
As the water passes through a water softening appliance containing a bed of resin, the hardness (calcium and magnesium) present in the water is exchanged or swapped for the sodium found in the resin. When the available sodium has all been exchanged for calcium and magnesium, hard water is present in the softener outlet, and the resin must be regenerated. Common salt is used to replenish the supply of sodium in the resin, and the hardness is flushed as waste.
02. Water Softener Questions — General
You do not need to clean out a brine tank. The only exceptions to this rule are if you use a salt product high in water-insoluble matter or the system experiences a major malfunction. If there is a build-up of insoluble matter in the resin, the reservoir should be cleaned out to prevent softener malfunction.
If your average water usage is 75 gallons per day per person, you will use an average of 48 to 85 pounds of salt per month, which is very little in comparison to most older systems that regenerate based on days instead of gallons used.
You may need a water softener if your water is hard and you want to reduce the negative effects it has on your home and daily life. Hard water can cause mineral build-up in pipes and appliances, leading to decreased efficiency and shortened lifespan. It can also leave spots and stains on dishes and clothing, make soap and detergents less effective, and leave your skin feeling dry and itchy.
Residential water softeners remove the dissolved minerals that cause hardness, resulting in cleaner and softer water throughout your home. A water softener can help save you money on repairs and replacements of appliances and plumbing fixtures, improve the effectiveness of your cleaning products, and provide softer and more manageable hair and skin.
At Serv-All Water Conditioning, we custom-build all of our water treatment systems based on the home’s water quality and the customer’s needs and wants. Because of this, we have the capability to design a system to remove chlorine, chloramines, as well as a broad spectrum of other potentially harmful contaminants found in tap water to keep your family happy and healthy.
By all means, you can use soft water for cooking and making coffee. Hard water actually reacts with some foods, robbing them of taste. For example, peas are shriveled by hard water and stay round in soft water. Good-tasting coffee is more easily prepared when soft water is used. Install a water softener today and see for yourself how much the taste of your food and drinks improve!
Hard water leaves nasty stains behind that require harsh chemicals and detergents to remove. When you have soft water flowing through your faucets, you don’t have to worry about these stains, significantly reducing the cost of your cleaning supplies.
Tired of streaks and spots on glassware and dishes? Conditioned water eliminates the problem and helps your dishwasher last longer, too!
Red, roughened hands are usually the by-product of hard water. Conditioned water caresses and doesn’t irritate.
Clothes last longer and come out fresher, cleaner, and softer when washed in conditioned water. Colors stay brighter, too.
Bring conditioned water to your bath or shower, and you’ll feel a refreshing difference. You’ll wash “really clean” faster and without soap build-up on your skin.
Say goodbye to razor burn as your razor glides smoothly over your soft water-conditioned face. Both your skin and blades will last longer.
A shampoo combined with conditioned water revives hair color and makes it more radiant and manageable.
Hard water scale corrodes and plugs valves in water-using appliances and shortens service life and saves you money.
Hot Water Guard
Conditioned water adds longer life to your water by minimizing the scale build-up created by hard water minerals and saves you money! Less energy is required (17% to 21%) to heat water in tanks without a scale build-up.
Washing floors, tile, and woodwork goes much easier and faster with conditioned water because it eliminates the film and soap scum that hard water causes.
Over a period of time, scale forms and clogs your plumbing. As the pipes clog, water flow is restricted and water pressure can be reduced dramatically. A water conditioning system minimizes this headache.
A water softener is a water treatment system where the calcium and magnesium carbonate (the minerals responsible for the hard water) are replaced with either sodium chloride (salt) or potassium chloride. This is different from a water filter in that filters will generally remove chlorine, pesticides, bacteria (in some cases), and suspended particles (sand, sediment, etc). A filter will not remove dissolved solids (which are responsible for hard water).
If you’re using sodium chloride (salt), then the softener will add a small amount of sodium to the water. For most people, this is not a problem. However, if you’re on a sodium-restricted diet, we would recommend a separate faucet in the kitchen that dispenses unsoftened water for drinking. Additionally, some people take a while to get used to the feeling of softened water.
Some people may describe softened water as feeling slimy or slippery, especially when they first switch from hard water. This is because soft water has fewer dissolved minerals, like calcium and magnesium, which can give water a slightly “hard” feel. Other people describe softened water as feeling smooth and luxurious, as it can leave the skin feeling moisturized and silky. The sensation of sliminess is typically temporary, and many people adjust to the feeling of softened water over time. If you’re concerned about the feel of your water, you can try adjusting the settings on your water softener or contact a professional for assistance.
All softeners, regardless of price, should soften your water (i.e., reduce the hardness to 0 grains). When comparing residential and commercial water softeners, you should consider an array of factors over the price. For example, evaluate softener systems based on the following:
- How long the unit will last
- How often it regenerates
- How large the grain capacity is
- How easy it is to change the settings and service the unit
- What the warranty entails
- How long the company has been in business
- How quickly you can get your questions answered and your problems solved
Serv-All is available when you need us most to answer your most pressing questions about water softeners. Don’t hesitate to get in touch if you’re interested in installing a new water softener.
In many cases, it will! It depends upon the levels of iron present. We manufacture iron units for heavy iron problems. Please contact us for the correct iron-softener combinations for maximum service.
YES! While setting the computer-controlled valve head is extremely easy, cutting into your main water line with a torch to place the water softener is not something the typical homeowner should do on their own.
You may experience a slight water pressure drop from the water softener. However, our water softeners feature 1” ports for the maximum possible water flow and pressure.
03. Water Softener Questions — Technical
When you use salt in your water softener, the sodium ions in the salt replace the calcium and magnesium ions in the water, resulting in soft water. The amount of sodium that is added to the softened water depends on the hardness of the water and the amount of salt used in the softening process.
However, it’s important to note that the level of sodium in softened water is still considered safe for consumption by most health organizations, and there are other sources of sodium in many people’s diets, such as processed foods. If you have concerns about your sodium intake, you may want to consider using a potassium-based salt or another alternative method of water softening.
What Is the Difference Between the Water Softeners You Sell Over the Ones Offered by the Competition?
We include the important options on our systems that add up in price. For example, we install a commercial grade bypass on our Clack, Fleck, and Autotrol Systems and a stainless steel bypass valve on our Clack WS1, Fleck 5600, 5600SE, 2510, 2510SE, and 9000 Systems.
We also include:
- A brine well inside the brine / salt tank to keep the dirt and sediment from the salt plugging up the air check tube and the softener valve
- A safety float to keep the water level from getting too high and overflowing all over the floor if there is a problem with the system
- A grid plate / salt platform to help keep the salt from hardening up and solidifying
Magnetic water softeners, also known as magnetic descalers or anti-scale systems, are devices that claim to reduce the hardness of water without using salt or chemicals. These systems use magnets to create a magnetic field that alters the physical and chemical properties of the minerals in the water, making them less likely to stick to surfaces and form scale.
However, there is limited scientific evidence to support the effectiveness of magnetic water softeners. Some studies have suggested that these devices may have a small effect on reducing scale build-up, but others have found no significant difference between treated and untreated water. Additionally, many water treatment experts and organizations have expressed skepticism about the claims made by magnetic water softener manufacturers.
Always think about flow rates when choosing a water softener. Think about the number of showerheads and baths you have and the chances of using them all at the same time. For most folks, it is rare that all appliances and showers will be used all at once, so for the average home of less than 2300 square feet, a flow rate of 8 gallons per minute is more than enough.
Every once in a while, we run across a customer that has multiple body shower sprays in a shower stall. The average jet package has 4 to 5 sprayers, including the shower head. You need about 15 GPM to operate properly. In this case, you want to size your softener based on an 18 GPM flow rate. In this application, the Clack WS1 48,000 grain softener is the best choice.
We understand that the math associated with flow rates can make your head spin. If you’re interested in residential water softeners, our experts can help you determine the proper size for your home.
The preferred systems are all metered on demand. Water flow systems regenerate based on gallons used, so if the number of people in your home fluctuates, these systems will keep up with the usage. If you go on vacation, they will not regenerate due to no water being used. We also carry timed systems that regenerate based on days, which are great for well water when trying to remove more than 3 ppm or mg/L of iron. The timed systems help keep the resin bed clean from the iron and keep costs low.
Yes, but potassium will cost a lot more than salt.
We answer service calls within one to two business days. Sometimes, we can even address your request for a water softener repair within the same day!
How Do You Handle Warranty Issues, and What Is the Warranty on Your Water Softeners and Iron Filters?
If you have a problem with your equipment, you can do two things. Call us, and we will walk you through the troubleshooting, which is easy to do. If that does not work, we will send a technician out to try to fix the problem.
If it is before one year of the installation date, then there is no trip charge. But after one year, there will be a charge. If it is a defective part that is under warranty, we will change it out on-site and take the broken part back to ship it to the manufacturer.
The control valves have a five-year warranty, and the tanks have a ten-year warranty.
What Is the Difference Between the Purolite C-100 E High Capacity Resin That You Generally Use and an Ionics C-249 Resin?
Nothing, they are both cross-link 10% resins and are very durable and respected in the industry. Not every situation is the same, but the average life of a good resin is ten years or more. We can help you replace the resin once it goes bad.
A water softener is typically installed near the main water supply line where it enters your home. This can be in a basement, garage, utility room, or other suitable location. When installing a water softener, it’s important to ensure that it is placed in an area that is protected from freezing temperatures, moisture, and direct sunlight. A drain line should also be installed to allow the system to discharge the salt brine solution that is used to regenerate the system.
Installation of a water softener requires some basic plumbing knowledge and skills, and it’s recommended that you consult with a professional plumber or water treatment specialist for assistance. We can help you determine the best location for your water softener, install the necessary plumbing connections, and ensure that the system is set up correctly for optimal performance.
The lifespan of a water softener depends on several factors, including its quality, usage, maintenance, and the hardness of the water being treated. On average, a well-maintained water softener can last for around 10-15 years or more before needing to be replaced or repaired.
Regular maintenance is key to ensuring the longevity and efficiency of your water softener. This includes monitoring salt levels, cleaning the brine tank, checking and replacing filters as needed, and scheduling periodic professional inspections and tune-ups. Neglecting regular maintenance can lead to decreased performance, increased repair costs, and shortened lifespan.
The regeneration cycle is a key process in the operation of a water softener. During the softening process, a resin bed inside the water softener collects the hard water minerals and exchanges them with sodium ions from the salt used in the system. Over time, the resin bed becomes saturated with these minerals and needs to be regenerated, or “recharged,” in order to continue effectively removing hardness from the water.
The regeneration cycle typically involves several steps, including backwashing, brine refill, and rinsing. During the backwash phase, water is directed through the resin bed in the opposite direction to flush out any accumulated sediment or debris. Next, the brine tank is filled with saltwater, which is then drawn into the resin bed to remove the accumulated minerals. Finally, the system rinses itself with fresh water to wash away any remaining salt or mineral particles.
One gallon of water will dissolve three pounds of salt. So for one pound of salt, at least three gallons of water should be in the brine tank.
Do I Have to Have an Exact Amount of Salt in the Brine Tank for the Softener to Regenerate Properly?
The amount of salt placed into the brine storage tank has nothing to do with the amount of salt used during the regeneration cycle. Water will dissolve and absorb salt only until it becomes saturated. A given amount of brine (salt-saturated water) contains a specific amount of salt. Just make sure that there is at least enough salt for a regeneration cycle (8 lbs in the case of our unit).
04. Water Softener Myths
Companies who are selling competing products have perpetuated a number of myths about water softeners in an attempt to make their products look more attractive. The truth is that a water softener is the most reliable and cost-effective way of eliminating hardness in tap water, which causes so many problems throughout the home.
NO. Salt is sodium chloride, and water softeners add just a small amount of sodium to your water…but there is already sodium in the water before it even reaches the water softener.
This is a hugely misunderstood subject in the water business. People think water softeners also add chloride to the water, which is not true. All the chloride from the salt used in a water softener goes down the drain, and none is added to the water supplied to your home. If water softeners added chloride to the water, the water would taste like ocean water, but it does not.
Reasonable levels of sodium are not bad for most people — in fact, Gatorade has a large amount of sodium in it. People on a restricted-sodium diet should not drink tap water either before or after a water softener because they will both contain sodium. When on a sodium-restricted diet, only drink water processed through reverse osmosis or bottled water, which has no sodium.
Yes and no. A plaster swimming pool needs a small amount of calcium in it so the water remains balanced. Because soft water has no calcium in it, the water is out of balance and could attack the plaster, trying to get back into balance.
It is almost impossible to fill a swimming pool with soft water because you would have to stop filling the pool every couple of hours while the water softener regenerates. Because calcium is a solid and not a liquid, it does not evaporate like the water does. Once the calcium is in the pool, it will always be there until you drain the pool.
For this reason, it is very beneficial to add soft water to a pool to replenish the water that is lost to evaporation. It will keep the calcium at a reasonable level and make your tiles easier to clean. If you continue to add hard water to the pool to replenish for evaporation, the calcium continues to build because it does not evaporate. Eventually, you will have to drain your water and refill the pool because it has too much calcium in it.
05. Reverse Osmosis Questions
Yes, reverse osmosis-treated low-mineral water is considered safe and healthy to drink. In fact, many people prefer the taste and purity of reverse osmosis water over tap water or other types of bottled water. Reverse osmosis (RO) is a highly effective water filtration process that removes impurities such as heavy metals, chemicals, and bacteria from the water. If you’re interested in reverse osmosis systems, speak to the specialists at Serv-All Water Conditioning today!
No, reverse osmosis-purified water is not unhealthy to drink. In fact, many people consider it to be one of the safest and purest forms of drinking water available. Reverse osmosis is a highly efficient water purification process that removes up to 99% of impurities, including contaminants such as lead, arsenic, fluoride, and chlorine. While some critics argue that RO water may also remove beneficial minerals, the overall health benefits of drinking purified water outweigh any potential drawbacks.
A reverse osmosis filter removes unhealthy organic material. However, some healthy minerals, such as calcium, magnesium, and potassium, may be removed at the same time. However, it’s important to weigh the effects of leaving these minerals in with taking them out. These minerals can contribute to hard water deposits, scale build-up, and other water quality issues. While some people prefer to retain these minerals in their drinking water, others argue that they can obtain them from other sources, such as fruits, vegetables, and supplements.
No, reverse osmosis does not leach minerals from the body. In fact, the body cannot absorb minerals from water as efficiently as it can from food sources. While some people may be concerned that drinking RO water may deplete their mineral levels, the overall effects on health are negligible. Studies have shown that most people obtain the majority of their essential minerals from food, not water.
No, reverse osmosis filtration does not produce very acidic water with low pH. While RO water may have a slightly lower pH level than tap water due to the removal of alkaline minerals, it is still considered safe and healthy to drink. Some people prefer to add mineral drops or a remineralization filter to RO water to restore its pH balance and make it more alkaline.
Tap water in most cities is generally considered safe to drink according to government regulations. However, water quality can vary by location, source, and treatment methods used. Some contaminants, such as lead, pesticides, and bacteria, may still be present in trace amounts even if the water meets regulatory standards. Many people choose to use home water filters or opt for bottled or purified water to ensure the highest quality of drinking water.
RO water is generally considered to be comparable to bottled water in terms of quality and taste. Both types of water undergo stringent filtration and purification processes to remove impurities and contaminants. While bottled water may contain minerals and other additives for flavor or health benefits, RO water is typically pure and unadulterated. Some people prefer the taste of RO water over bottled water due to its freshness and lack of plastic or other packaging.
Reverse osmosis is considered to be one of the most effective water filtration and purification methods available. It is capable of removing up to 99% of impurities and contaminants, including heavy metals, chemicals, bacteria, and viruses. Compared to other methods, such as activated carbon filters, UV disinfection, or distillation, RO typically provides the highest level of purity and safety for drinking water. However, it may also be more expensive or require more maintenance than other methods.
Every year! Here at Serv-All, we will call and send a postcard to remind you that you are due for your routine filter change. The cost is anywhere between $45 and $85, depending on what stage reverse osmosis system you have.
What if I Don’t Use My Reverse Osmosis System All the Time — Do I Still Need to Change the Filters Every Year?
Yes! The reason why you need to change the filter regularly is the water still sits on the filters. Another reason is that if your ice maker is hooked up to the reverse osmosis system, it is constantly sending water to your ice maker.
The whole reason behind a filter change is to protect the membrane filter — the filter that you change out every three to five years. That filter is the heart and soul of the whole system. If that goes bad, your water will taste bad and will cost you more money down the road. Also, if the filters clog up, that could cause damage and break the system. Don’t let this happen to you! Change your system’s filter every year! | Yes |

Mexedrone is a legal chemical drug or stimulant that has been under development for the last two years. So far, it is still legal in Europe and available for distribution for the UK market. It has a similar structure to Mephdrone (4mmc) that was banned from the UK market about 5 years ago. Continue reading
3-MeO-PCP is a dissociative drug in the arylcyclohexamine class. Because name indicates, it relates to PCP by the addition of any methoxy collection. It is of comparable potency, with doses inside the 10mg place, but is more dissociative with less activity as being a DRI. Having a little good luck, this will lead to less activation and mania, and thus less on the crazy achievements the PCP is infamous pertaining to.
3-MeO-PCP acts as a strong dissociative drug in a similar fashion fot it of phencyclidine (PCP). While effects of the 2 compounds may end up being similar, they will not be identical, as 3-MeO-PCP incorporates a binding profile for that target receptors that’s slightly altered fot it of phencyclidine (PCP).

4-MEC is often compared to mephedrone. Both of which are referred to as stimulants. It is indeed a synthetic stimulant that is chemically engineered. In 2010 it was decided to start it sales online, on the World Wide Web. Quickly after that in 2011 it was produced as a powder and no longer a pill or capsule form was desired. 4-MEC is often used to grab that artificial high that so many individuals desire, without taking a street or illegal drug. Because the redose of 4-MEC is often times stronger than the initial dose, it is difficult not to redose. And that is drives individuals to continue to buy it both online and from individuals selling it direct.
There are medical benefits to taking 4-MEC however; it should not be considered only a drug or a stimulant for those looking for that artificial high. It has been proven to assist the body tissues regrow after an injury. Not only does it assist them in regrowth, but they in fact grow back stronger than they initially were prior to being injured. The reason being is that 4-MEC takes control over the stimulation in the brain that helps repair the bodily tissues. Therefore it is telling the brain to repair itself, and to do a better job this time around!
Along with repair to your injured body, 4-MEC also assists in lowering the fat on the body. The actual fat content in the tissues will and have been proven to be lowered with the extended use of 4-MEC. This is mainly due to the fact the stamina is increased enough to get a person up and moving more. More movement allows for the burning of fats left over on the body. Daily movement and chores that was once difficult, just got allot easier with the extended use of this chemical!
Legal and lethal are to entirely different words, however are grouped under the same category allot of the time. There are websites that are ran by regular people in the UK and beyond that are selling these research chemicals to anyone who can click a mouse. Too often the chemicals are referred to as ‘novel’ or ‘organic’ which in some strange way makes them seem less addictive or less harmful. Neither is true I am afraid.
There is actually a couple that many of their family and friends wondered where their income came from. Since neither of them worked out of the house and yet they had a gorgeous home, multiple cars, and their three children were in private schools! Their only answer to the questions asked was that they had a very lucrative web based business. In fact, that business was the sale of research chemicals. They left out the part where they were actually selling substitutes of marijuana, amphetamines, and even hallucinogens. All of which were able and legal to be purchase online.

Mouse Endostatin ELISA Kit - 1 Kit (96 Wells)Our Mouse Endostatin ELISA Kit is a sandwich ELISA intended for the quantitative determination of mouse Endostatin in cell culture supernates, serum and plasma (heparin, EDTA).
Endostatin is a naturally-occurring 20-kDa C-terminal fragment derived from type XVIII collagen. It is reported to serve as an anti-angiogenic agent, similar to angiostatin and thrombospondin. And It is produced by proteolytic cleavage of collagen XVIII, a member of the multiplexin family that is characterized by interruptions in the triple helix creating multiple domains, by proteases such as cathepsins. Using a genomic clone as a probe for fluorescence in situ hybridization, Endostatin was mapped the COL18A1 gene to 21q22.3. By immunoprecipitation analysis using membrane fractions of human mammary epithelial cells, It showed that endostatin specifically bound to cell surface nucleolin with high affinity. Blockage of nucleolin with neutralizing antibody or knockdown of nucleolin by RNA interference countered the antiendothelial activity of endostatin and abrogated its antiangiogenic and antitumor activity in vivo. | Yes |

Italian energy company Italgas has partnered with cement producer Buzzi Unicem to help the company decarbonise the production of cement using power to gas and carbon capture systems.
The two companies will conduct a study in which they will combine power to gas and carbon capture at Buzzi Unicem’s production facilities for decarbonisation of cement and concrete production.
Synthetic methane will be produced from green hydrogen acquired during the power to gas process and carbon emissions released and trapped during the production processes will be used to power Buzzi Unicem’s cement and concrete plants.
Italgas will leverage its experience gained in projects implemented in Sardinia where the company produced green hydrogen from a power to gas system, which was used to decarbonise transport and energy-intensive industries.
The collaboration falls under efforts by the two companies to ensure environmental sustainability whilst expanding their presence in the low-carbon energy business sector.
Paolo Gallo, the CEO of Italgas said: “We strongly believe in Power to Gas technology and in its strategic contribution to the energy transition in terms of sector coupling.
“The production of hydrogen from renewable sources enables the use of gas networks in the dual function of carrier and energy storage asset, ensuring greater flexibility to the system.

A molly gummy combination of drugs packed into gummy bears is making its way into the hands of unsuspecting young users. Molly gummies are often mixed with MDMA and other chemicals that are not always identified or labeled. The drug has been glamorized in pop culture, featuring in music by artists like Kanye West, Rick Ross, Miley Cyrus, and Madonna.
The chemical MDMA (3,4-methylenedioxymethamphetamine) is known for euphoric effects that create feelings of emotional closeness and empathy with others. It also alters perception and provides a burst of energy. The National Institute on Drug Abuse explains that MDMA works by binding to serotonin transporters in the brain and blocking their normal function, causing a boost in mood, increased heart rate, reduced appetite, and heightened sensory perceptions.
Microdosing Molly: A Beginner’s Guide to Safe and Effective Use
When taken in its usual doses, MDMA increases the activity of neurotransmitters norepinephrine, dopamine, and serotonin. It can increase heart rate and energy, elevate mood, and reduce anxiety or depression. It can also lead to dangerous side effects, including paranoia and psychosis, or cause people to experience suicidal thoughts or acts.
Long-term use of MDMA can cause physical dependence and addiction, as well as deplete the brain’s natural production of important chemicals. It can also increase the sensitivity of some people to other substances, such as opioids or stimulants. It can also interact with certain medications, notably antidepressants and sedatives used to treat mental illness. And it is often adulterated with other substances, such as the synthetic drug bath salts or the painkiller fentanyl. | Yes |

The effect of the positional distribution of docosahexaenoic acid (DHA) within triacylglycerol (TAG) molecules on the oxidative stability of oil-in-water emulsions was investigated by using a synthetic TAG regio-isomer pair SDS (1,3-dioctadecanoyl-2-[4,7,10,13,16,19-docosahexaenoyl] glycerol) and SSD (1,2–dioctadecanoyl-3-[4,7,10,13,16,19-docosahexaenoyl] glycerol), where S and D represent stearic acid and DHA, respectively. Oil-in-water emulsions (10%, w/w) of each isomer were subjected to accelerated autoxidation by continuous exposure to air at 50C in the absence of light. Oxidation during the exposure (storage) was monitored by measuring a series of volatile compounds characteristic of DHA oxidation. SSD emulsion oxidized faster than SDS emulsion, showing that DHA is more stable to oxidation when located at the sn-2 position of the TAG compared with the sn-1(3) position. This regio-isomeric effect is similar to that previously reported for bulk oil oxidation.
Many of the food products that have been selected for fortification with omega-3 oils such as milk, yoghurt, salad dressings and juices are oil-in-water emulsions. This study, for the first time, demonstrated that the regio-isomeric effects on oxidative stability of docosahexaenoic acid observed for bulk oil also apply to oil-in-water emulsion. Thus, potential exists for enhancing the oxidative stability of omega-3-fortified emulsion foods through modification of triacylglycerol structure. | Yes |

Polymer-matrix nanocomposite membranes for water treatment
One of the grand challenges to sustain the modern society is to secure adequate water resources of desirable quality for various designated uses. To address this challenge, membrane water treatment is expected to play an increasingly important role in areas such as drinking water treatment, brackish and seawater desalination, and wastewater treatment and reuse. Existing membranes for water treatment, typically polymeric in nature, are still restricted by several challenges including the trade-off relationship between permeability and selectivity (also called Robeson upper boundary in membrane gas separation), and low resistance to fouling. Nanocomposite membranes, a new class of membranes fabricated by combining polymeric materials with nanomaterials, are emerging as a promising solution to these challenges. The advanced nanocomposite membranes could be designed to meet specific water treatment applications by tuning theft structure and physicochemical properties (e.g. hydrophilicity, porosity, charge density, and thermal and mechanical stability) and introducing unique functionalities (e.g. antibacterial, photocatalytic or adsorptive capabilities). This review is to summarize the recent scientific and technological advances in the development of nanocomposite membranes for water treatment. The nanocomposite membranes were classified into (1) conventional nanocomposite, (2) thin-film nanocomposite (TEN), (3) thin-film composite (TFC) with nanocomposite substrate, and (4) surface located nanocomposite, based on the membrane structure and location of nanomaterial. Challenges and future research directions in developing high performance nanocomposite membranes were also discussed. (c) 2014 Elsevier By. All rights reserved. | Yes |
Learn the science behind:
Everthing new starts by understanding the basics. One of the basic ingredients used in food is butter. This one-page infographic should help you understand all the science basics when it comes to butter.
Just a heads up, I’m based in Europe so the composition of butter I mention is the European law. Details might be different in other countries, but the general idea is the same :-).
Butter is made from milk and as you can see consists of mostly fat and water as well as some proteins. Butter is used a lot in baking, as are margaring and shortening. Butter though is fundamentally different from margarine and shortening since those two aren’t made from milk. Besides that, there are some other differences in the fat composition which causes them to have slightly different properties. Therefore, they might be firmer or softer in the fridge or at room temperature than butter.

Biomass can be used to produce renewable electricity, thermal energy, or transportation fuels (biofuels). Biomass is the only source of fuel for domestic use in many developing countries. Biomass is all biologically-produced matter based on carbon, hydrogen, and oxygen. Unlike other renewable energy sources, biomass can be converted directly into liquid fuels - biofuels - for our transportation needs (cars, trucks, buses, airplanes, and trains). The two most common types of biofuels are ethanol and biodiesel. Ethanol is mostly used as a fuel additive to cut down a vehicle's carbon monoxide and other smog-causing emissions. The energy stored in biomass can be released to produce renewable electricity or heat. Bio-power can be generated through combustion or gasification of dry biomass or biogas (methane) captured through controlled anaerobic digestion. Co-firing of biomass and fossil fuels is a low-cost means of reducing greenhouse gas emissions, improving cost-effectiveness, and reducing air pollutants in existing power plants. A number of transportation fuels can be produced from biomass, helping to alleviate demand for petroleum products and improve the greenhouse gas emissions profile of the transportation sector. | Yes |
The Galvalibs 2.0 is the new method to directly monitor the dross level of a galvanizing bath. The old way involves manually sampling the bath, followed by laboratory analysis and model-based corrections. Getting a good, consistent sample from the depths of the bath, without contamination from floating dross, is already a challenge.
What’s more, laboratory results must be corrected with temperature-dependent solubility models, so the traditional method may produce uncertain or unreliable results. The Galvalibs 2.0 provides a continuous automatic value of the dross level in suspension. No need for temperature correction. No need for bath sampling.
The Galvalibs 2.0 displays reliable, continuous monitoring of the dross level. Evolution and trends are clearly observed since there are no blind zones and no time lag typically encountered with periodic manual sampling and processing. That means that operators can relate an unexpected rise in the dross level to plant events or activities, such as residual iron fines or bath temperature instabilities.
The Galvalibs 2.0 monitors the dross level in suspension in the bath. When a line is stopped, there’s no turbulence in the bath and the dross slowly drifts to the surface or the bottom with very little dross in suspension. The first circle in the figure shows the time when a galvanizing line was stopped, while the second circle indicates the time when the line was restarted. The dross measurement quickly drops to zero when the line is stopped and slowly rises when the line is restarted, clearly demonstrating the Galvalibs’ sensitivity to dross levels.
The galvanneal process produces a high level of bottom dross (heavy particles) as residue. Periodically, a galvanneal bath needs to be cleaned by adding a large amount of aluminum. Bottom dross is then transformed into top dross, which is removed by skimming. As the dross migrates from the bottom to the surface, the Galvalibs 2.0 can see the passing dross in suspension (see figure). Once the transformation of bottom-to-top dross is completed, the recorded dross level reverts to normal. Operators can use this information to easily determine when the transformation process has been completed.
Dross is caused by an excessive Fe pushed into the bath during the steel and molten metal’s surface reaction when they enter the bath. Since Fe is continuously above saturation levels, rapid local temperature changes in the bath will play an important role in dross formation.
