The design and the use of highly active catalysts could diminish the amount of transition metal complexes, extend ATRP to less active monomers and give access to new chain〆nd functionalities. At the same time, very active catalysts can be involved in formation of organometallic species. Herein,...
The microwave and fast-food chains were the biggest catalysts(催化剂) but the big food companies-which want to sell anything except the raw ingredients that go into cooking-made the home cook an endangered species. [I] I find it strange that only a third of young people report preparing ...
Why do enzymes have different optimal temperatures?Describe how enzymes catalyze chemical reactions without being used up.How are enzymes regulated?Why do bacteria use restriction enzymes?How do enzymes speed up reactions?Why do we need enzymes to stay alive? How do enzymes help us in our daily ...

For many working in France’s infrastructure industry, the goal is to use these new forms of transport as catalysts for the development of both on-board and on-road technologies. This vision is supported by Hervé Dumont, director of Forecasting, Technology, and Development at Eiffage Route, a...

Synthetic Rubber is any type of artificial elastomer, invariably a polymer. It is produced in factories with the use of different catalysts. The feedstocks for synthetic rubber industry are products of the petrochemical industry.In general, synthetic rubber offers better resistance to abrasion than nat...
Why do we need solvents? In chemistry, solvents – which are generally in liquid form – areused to dissolve, suspend or extract other materials, usually without chemically changing either the solvents or the other materials. What is a good solvent?
