The extent of the changes depended on the concentration and oxidizing power of oxidant and the immersion time.
Dsb proteins are known to oxidize the sulfhydryl groups of periplasmic proteins to disulfide bonds, donating electrons to ubiquinone, and thereby making the electron transport chain the primary source of oxidizing power for sustaining periplasmic sulfhydryl oxidation [ 19, 20].
Root oxidizing power due to oxygen release or enzymatic oxidation is responsible for the oxidization and precipitation of Fe2+ on the root surface, thus avoiding excess Fe2+ from uptake into rice shoots (Ando et al. [1983]; Green and Etherington [1977]).
Root oxidizing power as a direct cause of Fe2+ oxidation is assumed to be composed of two distinct processes: root oxygen release and enzymatic oxidation (Ando et al. [1983]).
However, some naturally occurring minerals are known to facilitate the photochemical oxidation of water to molecular oxygen; such "photochemical sources of oxidizing power in low-oxygen environments" [137] may be active alongside or in place of other sources of oxygen such as air or photosynthetic organisms.
Oxidizing power of the atmosphere.
Atmospheric evolution and human influence; basics of greenhouse effect, photolysis, reaction kinetics; atmospheric transport of trace species; stratospheric ozone chemistry; tropospheric hydrocarbon chemistry; oxidizing power, nitrogen, oxygen, sulfur, carbon, mercury cycles; chemistry-climate-biosphere interactions; aerosols, smog, acid rain.
It is shown that differences in oxidizing power between cyclic and non-cyclic compounds are not due to differences in their reduction potential.
Interestingly, depending on the reducing or oxidizing power of the selected redox mediator, the SECM response changes from slow (case of electron donor) to fast (case of electron acceptor) electron transfer rate.
On the other hand, complex oxidation reactions leading to the partial incineration of polymeric materials can take place on the Ta/β-PbO2 surface due to electrogenerated HO radicals which have an oxidizing power much higher than that of intermediaries formed respectively on IrO2 and Pt.
They used electrical current as alternative source of reducing or oxidizing power to guarantee different redox conditions for production.
