APOBEC3G (apolipoprotein B mRNA editing enzyme, catalytic subunit 3G) is a human enzyme encoded by the APOBEC3G gene that belongs to the APOBEC superfamily of proteins. [4] This family of proteins has been suggested to play an important role in innate anti-viral immunity. [5]
The oxide is obtained as a black powder. The oxide also may be prepared specially for catalytic use by heating variously a mixture of palladium(II) chloride and potassium nitrate, 2 PdCl 2 + 4 KNO 3 → 2 PdO + 4 KCl + 4 NO 2 + O 2 (possible reaction) or the product of dissolving palladium in aqua regia, followed by the addition of sodium ...
Catalytic cycle for the Wacker process. [8] The initial stoichiometric reaction was first reported by Francis Clifford Phillips in his doctoral dissertation on the composition of Pennsylvanian natural gas defended in 1893. [9] This net reaction can also be described as follows: [PdCl 4] 2 − + C 2 H 4 + H 2 O → CH 3 CHO + Pd + 2 HCl + 2 Cl −
A number of ruthenium-aqua complexes catalyze the oxidation of water. Most catalysts feature bipyridine and terpyridine ligands. [3] [4] [2] Catalysts containing pyridine-2-carboxylate exhibit rates (300 s −1) comparable to that of photosystem II. [5] [6] Work in this area has ushered in many new polypyridyl ligands. [7] [8]
Carl D. Keith (left) and John J. Mooney at the award ceremony for the National Medal of Technology and Innovation for the invention, application and commercialization of the three-way catalytic converter (2003) The 1970 amendments to the Clean Air Act required significant reductions in hydrocarbon, carbon monoxide and nitrogen oxide emissions.
Hydrogenation of ethene on a catalytic solid surface (1) Adsorption (2) Reaction (3) Desorption. Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reagents or products. [1] The process contrasts with homogeneous catalysis where the reagents, products and catalyst exist in the same phase.

Historically, Wilkinson's catalyst has been a paradigm in catalytic studies leading to several advances in the field such as the implementation of some of the first heteronuclear magnetic resonance studies for its structural elucidation in solution (31 P), [3] parahydrogen-induced polarization spectroscopy to determine the nature of transient ...
