Simultaneously, protons that migrate through the [Nafion.sup.5] 117 membrane to the cathode compartment reduce oxygen to water and reoxidize
ferrocyanide to ferricyanide.
Then the reduced mediator carrying electrons would reoxidize
after depositing the electrons on the electrode.
High in density, they do not reoxidize
or generate fines.
Experimentally, [F.sub.0]' is often measured by applying a pulse of far-red light to the sample after turning off the actinic light, in order to preferentially stimulate the PSI activity and reoxidize
reduced electron transporters located uphill.
* Penetrate the OSP and provide a barrier on the cleaned metallic surface; otherwise the freshly exposed surfaces will easily reoxidize
in the atmosphere, accelerated by the elevated soldering temperatures.
However, it has been stated that nitrites can more rapidly reoxidize
metal surfaces, thereby quickly repairing the damage caused by cavitation.
As a liquid at steel temperatures, Ca aluminates improve the metal flow and lessen the blockage, allowing a tighter pouring stream with less surface to reoxidize
Third, the incorporation of oxidizing agents in the coolant which would reoxidize
the cleaved sulfur-sulfur bonds, is a possibility.
This high flow velocity impacting a mold or core could precipitate erosion defects and cause a sensitive alloy to reoxidize
upon entering the mold cavity.
It is possible that [H.sub.2][O.sub.2] that is formed in the course of CA oxidation  reoxidizes
ABTS into [ABTS.sup.+] and therefore results in overall smaller d[DELTA]A/dt at shorter incubation times, until it is used up.
Redox cycling occurs when a reduced quinone substrate such as menadione or doxorubicin spontaneously reoxidizes
in the presence of oxygen, thereby reducing the oxygen molecule .
