A possible solution is the development of processes using enzymatic, homogeneous or heterogeneous catalysts. In this review, selected examples of clean heterogeneously-catalyzed reactions applied to the synthesis of fine chemicals are reported for the purpose of highlighting the growing need for more ...
What is a Catalyst? - Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. A brief discussion on definition of Catalyst, activity and selectivity of Catalyst is given here.

Lindlar catalysts, which are available for commercial purchase, are also prepared in laboratories with the reduction of palladium(II) chloride in semi-liquid calcium carbonate and the subsequent poisoning of the resulting mixture with a suitable catalyst poison. Common choices here are lead acetate, l...

In this paper, we propose that during a complex engagement scenario with heterogeneous targets, the defence can use a SLS-OLEO (Shoot-Look-Shoot with Optimal Last Engagement Opportunity) firing tactic... A Progress Review of Multiplex Biosensors with Microfluidic Chip Last...
CuI-exchanged solids based on zeolite materials were investigated for the first time as catalysts in organic synthesis. The catalytic potential of these materials was evaluated in the Huisgen [3 + 2]-cycloaddition. Five CuI-exchanged zeolites were examined and CuI-USY proved to be a novel and ...
The current main concern of global sustainable development pushes toward the substitution of corrosive and highly waste-producing chlorine-containing conventional catalysts (such as the strongly acidic AlCl3–HCl mixture, still widely used in the production of chemicals) by environmentally friendly systems....
