β-Hydrogen Kinetic Effect

Journal of the American Chemical Society, 2007
A combined kinetic and DFT study of the uncatalyzed isomerization of cationic solvent complexes of the type cis-[Pt(R‘)(S)(PR3)2]+ (R‘ = linear and branched alkyls or aryls and S = solvents) to their trans isomers has shown that the reaction goes through the rate-determining dissociative loss of the weakly bonded molecule of the solvent and the ...

Effect of Alkaloids on Hydrogen Overpotential

Nature, 1947
IT is well known that certain substances, such as arsenious oxide1, when added to a solution in which is a working electrode evolving hydrogen, considerably increase the hydrogen overpotential at the cathode. Such substances are often referred to as 'poisons' 2, and a detailed knowledge of their effects on irreversible electrode potentials appears to ...

Effect of Hydrogen on Surface of Niobium

MRS Proceedings, 1998
ABSTRACTNiobium single crystals are used as substrate material for constructing superconducting quantum interference device or SQUID. The use of niobium is prompted by the fact that it is a low Tc metallic superconductor. In order to fabricate the device the surface of the crystal has to be polished flat.

Effect of Hydrogen Radical on Properties of Hydrogen in Hydrogenated Microcrystalline Silicon

MRS Proceedings, 2000
ABSTRACTHydrogenated microcrystalline silicon (μc-Si:H) films are prepared by hot-wire assisted plasma enhanced chemical vapor deposition, which controls the hydrogen radical density by filament temperatures, Tf, without changing other conditions. The effect of hydrogen radical on the properties of incorporated hydrogen into μc-Si:H films is studied ...

Effect of solvent and hydrogen during selective hydrogenation

Tetrahedron Letters, 2001
Abstract Described is the solvent effect for the chemoselective hydrogenation of alkenes having a benzyloxy group (Bn-O-) using a hydrogenation system employing atomic hydrogen permeating through a Pd sheet electrode.
