Hydrogen implanted silicon oxidation
Journal of Electronic Materials, 1989The oxidation rate and the oxide thickness of the hydrogen ion implanted silicon wafers were examined. It was observed that the native oxide thickness is higher for the H+ implanted Si(100) compared to the Si(111). Also the native oxide thickness depended on the implanted hydrogen distribution.

Combustion and Flame, 1981
An experimental and modeling study of the oxidation of H2S is reported. The experiments entailed induction time measurements in reflected shock waves, in 4 to 22% H2S in air, some of which contained from 1.6 to 13% H2O, with P1 = 1 atm and 950 < T5 < 1200°K.

Abstract Many transition metal oxides (and oxide hydrates) MO n ·mH 2 O (m = 0,1,2) react at ambient temperature with dissociated hydrogen to form non-stoichiometric hydrogen insertion compounds H x MO n ·mH 2 O which exhibit unusual electronic and structural features. In this paper the structure, bonding and proton mobility in compounds of this type

Physica B+C, 1985
Abstract Classical computer simulation techniques may not be appropriate for systems involving hydrogen or hydrogenic species since quantum-mechanical effects should be significant in such cases. We describe a combined quantum-mechanical/static lattice approach which interfaces both methods.

The Hydrogen-Oxidizing Bacteria
1981The group of aerobic hydrogen-oxidizing bacteria is physiologically defined and comprises bacteria from different taxonomic units. This group is defined by the ability to utilize gaseous hydrogen as electron donor with oxygen as electron acceptor and to fix carbon dioxide; i.e., to grow chemolithoautotro-phically.

[31] Oxidation with hydrogen peroxide
1972Publisher Summary Hydrogen peroxide is a relatively nonspecific oxidizing agent that reacts with a wide variety of organic compounds. The chemistry of the oxidation of proteins by this chemical has been extensively examined. It is found that under suitable, relatively mild conditions this reagent is highly specific for a small number of amino acid ...

Hydrogen Oxidation by Alcaligenes
1996Detailed molecular studies of hydrogen metabolism have progressed rapidly thanks to the development of genetic systems, which are now available for selected proteobacteria, including species of lithoautotrophs, nitrogen-fixing and photosynthetic microorganisms (reviewed by Friedrich, Schwartz 1993 and Vignais, Toussaint 1994).
