Oxygen factors governing

Perhaps the most interesting of the inner-sphere pathways are those which result in the net transfer of an oxygen atom. The factors governing the viability of this pathway are still speculative. For cobalt-02 adducts, thermochemical considerations suggest that oxygen atom transfer should be accompanied by electron transfer in the reverse direction. Similarly, this pathway should be enhanced for MO2 complexes in which the metal... 

Factors Governing Oxygen Reduction in Solid Oxide Fuel Cell Cathodes Stuart B. Adler... 

Alloys of noble metals have been tested for O2 reduction [31] and some should even be more efficient than Pt [63]. These metals are expensive so that other materials have been tested, like bronze, some being even slightly better electrocatalysts than platinum [45] however, they do not seem to be stable enough. The factors governing oxygen reduction on oxides used as cathodes in fuel cells have been reviewed recently [92]. 

Detailed work has been devoted to the elucidation of factors governing N-oxygenation of amino azaheterocycles. To this end, a series of substituted 2,4-diaminopyrimidines and 6-aminopurines was subjected to metabolic analysis8,16,64,65,147,148 Generapy5 P-450... 

High-temperature conditions such as those occurring in gas turbines or rocket propulsion units present severe conditions of operation to any metallic component. In such conditions, the hot gases attack the metal surface causing oxide formation (in the case of oxygen attack). In order for the metal to be serviceable under these conditions, oxidation must cease immediately a thin adherent film has formed on the metal surface, i.e. the film is protective. What factors govern the rate of scale formation in metal/hot gas reactions ... 

Selectivity in the oxidation of ammonia seems to be determined by the competition of NH3 and oxygen for a single type of active site, but the factors governing selectivity in the co-oxidation of ammonia and methane are obscure. The kinetics of HCN formation and of by-product formation should be examined under molecular beam conditions and over a wide temperature range so as to identify the important kinetic pathways.
