Copper Acetate

Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc)2 where OAc- is acetate (CH3CO2-). The hydrated derivative, which contains one molecule of water for each Cu atom, is available commercially. Anhydrous Cu(OAc)2 is a dark green crystalline solid, whereas Cu(OAc)2(H2O)2 is more bluish-green. Since ancient times, copper acetates of some form have been used as fungicides and green pigments. Today, copper acetates are used as reagents for the synthesis of various inorganic and organic compounds. Copper acetate, like all copper compounds, emits a blue-green glow in a flame. Copper(II) acetate was historically prepared in vineyards, since acetic acid is a byproduct of fermentation. Copper sheets were alternately layered with fermented grape skins and dregs left over from wine production and exposed to air. This would leave a blue substance on the outside of the sheet.

Palladium Acetate

Palladium(II) acetate is a chemical compound of palladium described by the formula Pd(O2CCH3)2 or Pd(OAc)2. It is considered more reactive than the analogous platinum compound. It is soluble in many organic solvents.
Palladium has a rich organometallic chemistry which has developed over the past twenty-five years. While palladium is not unique in its ability to carry out a wide range of carbon-carbon bond forming reactions, its ver- satility has resulted in an increasing effort being made towards the use of palladium reagents in organic synthesis in academic and industrial research laboratories.Widely used procedures such as the Heck, Suzuki and Sonogashira cross-coupling reactions and Buckwald-Hartwig aminations most commonly employ a palladium-based catalyst.

Swimming Pool

Swimming Pool or Pool means an artificial basin, chamber or tank used, or intended to be used, for public swimming, diving, or recreative bathing, but does not include baths where the main purpose is the cleaning of the body, nor individual therapeutic tub.
Swimming pools provide a great way to exercise and beat the summer heat. Building and maintaining a pool, however, also means relatively high costs added to your household’s budget.

Trifluoroacetic Acid

Trifluoroacetic acid (TFA) is the simplest stable perfluorinated carboxylic acid chemical compound, with the formula CF3CO2H. It is a strong carboxylic acid due to the influence of the electronegative trifluoromethyl group. TFA is almost 100,000-fold more acidic than acetic acid. TFA is widely used in organic chemistry.

TFA occurs naturally in sea water, but only in small concentrations (<200 ng/L). Therefore, TFA is prepared industrially by the electrofluorination of acetyl chloride and acetic anhydride, followed by hydrolysis of the resulting trifluoroacetyl fluoride.

  • It is produced by precipitation through filtering, heating and quenching works. Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper. It is used as a base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of applications in plastic industry. It is used as a filler in paper, leather, and linoleum.

Solvent Extraction

Solvent extraction (also known as chemical extraction) is a cleanup method that uses solvents to extract or remove harmful chemicals from polluted materials.
The greatest contribution in achievements of solvent extraction provided extractants based on hydroxyoximes. As they were synthesized there were no better copper extractants, and since then all investigations were performed in order to improve their properties.
With the recently developed technologies that are now under investigations in demonstration plants and ongoing research into improved technologies, we can safely predict that solvent extraction will eventually contribute to an increasing fraction of the copper produced each year not only from oxide but also from sulphide ores.

Renewable Energy Certificate

A REC represents the property rights to the environmental, social, and other nonpower qualities of renewable electricity generation.
RECs are known under functionally equivalent names such as Green Tags or Tradable Renewable Certificates (TRCs), depending on the market. The U.S. currently does not have a national registry of RECs issued.
In India there are several options for pricing renewable electricity such as using Market determined prices, linking prices to Unscheduled Interchange (UI) prices, setting the tariff for electricity generated from renewable resources as average power purchase price of the distribution licensee or fixing normative or feed-in tariff for particular renewable technology.

Greener Solvents

Green chemistry is a chemical philosophy encouraging the design of products and processes that reduce or eliminate the use and generation of hazardous substances.
There is growing interest in developing more environmentally acceptable processes in chemical or biotechnological industries. This trend towards what has become known as sustainable technologies can be defined as green chemistry and white biotechnology, when the emphasis is focussed on chemical or biotechnological processes, respectively

Gas Appliances

Gas appliances is a requirement of every household, therefore the demand for these appliances is likely to increase in the local as well as the foreign market. Furthermore, only a small proportion of the market share is taken up by imported appliances, which reinforces the fact that local products have a higher demand in the domestic market.
Total global trade in terms of imports of gas appliances was $6.394 billion in 2009. USA is the largest importing country with a share of 30.2% and a total value of $1.931 billion. USA is a rapidly growing market with high annual growth rate. Germany is the second largest importer in this category with imports of $529.590 million. France is the third largest importer with total imports of $496.905 million.

Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

Surfactants are usually organic compounds that are amphiphilic, meaning they contain both hydrophobic groups (their tails) and hydrophilic groups (their heads). Therefore, a surfactant molecule contains both a water insoluble (or oil soluble) component and a water soluble component. Surfactant molecules will diffuse in water and adsorb at interfaces between air and water or at the interface between oil and water, in the case where water is mixed with oil.

Synthetic Cells

The creation of the synthetic cell is part of an effort to design a "minimal cell" containing only the most basic genome required for life.

Biology, an emerging engineering discipline to program cell behaviors as easily as we program computers. Synthetic biology will improve our quantitative understanding of natural biological processes and will also have biotechnology applications in areas such as biosensing, synthesis of pharmaceutical products, molecular fabrication of biomaterials and nanostructures, and tissue engineering.

The ability to make artificial cells is a scientific milestone of immense proportions. Achieving it would mark a profound understanding of the biochemical systems that embody life, and it would also provide a fast track toward a series of fundamental scientific insights.

Starch Hydrolysates

Hydrogenated starch hydrosylate (HSH) is a mixture of several sugar alcohols (a type of sugar substitute).

Hydrogenated starch hydrolysates are produced by the partial hydrolysis of starch – most often corn starch but also potato starch or wheat starch. This creates dextrins (glucose and short glucose chains). The hydrolyzed starch (dextrin) then undergoes hydrogenation to convert the dextrins to sugar alcohols.

Hydrogenated Starch Hydrolysates are being used by the food industry for many years, especially in confectionery products. With time, they have become important food ingredients because of their sweetness, low cariogenic potential, and useful functional properties.
