Thus, the correlation coefficients between the electron donor contributions ([[gamma].
Assuming that the complete absorption of high EDN solvent can occur also in kukersite kerogen swelling, then the lines in Figure 5 correspond to "hypothetical swelling increase" that could be caused only by absorption of all drop-wise added strong electron donor solvent (NMP--a solid line, propylamine--a dashed line).
After that, the RC pigments capture electrons from the secondary electron donor and return to the former state.
Ammonia is the electron donor and nitrite is the electron acceptor.
The electron donor material used, TPP, minimized the crosslinking reactions but it also lowered the degree of functionalization.
When fenthion sulfoxide was incubated with rat liver cytosol in the presence of 2-hydroxypyrimidine, an electron donor of aldehyde oxidase, under anaerobic conditions, the extract of the incubation mixture inhibited the androgenic activity of DHT on NIH3T3 cells in the range of [10.
Most reducing equivalents from the electron donor (glucose) were consumed in reductive dechlorination, probably due to the inhibition of other microbial processes by the high chloroethene concentrations.
The easily oxidized guanine served as the electron donor.
3DMe's combination of wide-area dispersion and long-term electron donor supply makes it one of the most efficient and cost-effective in-situ remediation methods for the treatment of a long list of chlorinated contaminants, including widely used industrial degreasers such as perchloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE), vinyl chloride (VC), trichloroethane (TCA), chlorofluorocarbons, carbon tetrachloride, chloroform and methylene chloride, and many types of pesticides, explosives and dyes.
Accordingly, polymers P1-P2 carrying 1,3,4-oxadiazole as an electron acceptor moiety and 3,4-bis[(4-methy1/3methoxybenzyl)oxy] thiophene and 3,4-bis(dodecyloxy) thiophene as electron donors showed reduced band gap, while the polymer P3 containing 3,4-bis[(4-nitrobenzyl)oxy] thiophene as electron donor displayed slightly increased band gap.
2]) can also be used to selectively deliver a limiting electron donor to dehalogenating organisms and achieve complete dehalogenation of chlorinated aliphatic contaminants such as tetrachloroethene.
Its flexibility in the choice of electron donor chemicals can translate into capital and operating cost savings with reduced solids generation.
