Acetate, lactate, propionate, and iso butyrate as
electron donors for iron and sulfate reduction in Arctic marine sediments, Svalbard.
The surface amounts of the carbon fraction within the O--C-O groups for CMOX increased in comparison with the nonmodified OX film sample by about 225% and within the C-OH groups by about 34%, which had an influence on the increase in the
electron donor contribution of its SFE by about 270%.
8) relative to the strong
electron donor solvent NMP in the mixture.
islandicum owns the ability to reduce Fe (III) at 100[degrees]C in a medium with hydrogen as the
electron donor and Fe (III)-citrate as the electron acceptor.
Several molecules (1-6) have been synthesized containing the fragment TPA as an
electron donor (figure 1).
The major absorbance can be assigned to a ' Push - Pull' intramolecular charge transfer (ICT) sequence from
electron donor (thiophene or bromo thiophene) to acceptor (nitrobenzene or methoxy benzene) groups, indicating no significant affect due to the presence of bromine on the transition energy.
The adapted strain readily produced electrical current in microbial fuel cells with hydrogen gas as the sole
electron donor and no organic carbon source," said Kumar, who noted that when the hydrogen supply to the microbial fuel cell was intermittently stopped electrical current dropped significantly and cells attached to the electrodes did not generate any significant current.
The supramolecular system participating in electron transfer can be expressed by A-L-B, where A and B are
electron donor and electron acceptor respectively in electron transfer process and L is the "bridge" or coupling unit between A and B.
where it may undergo spin reversion to generate the lower energy triplet state of the excited primary
electron donor of PSII, [sup.
is used for cell growth, and is consumed by hydrogen ions in a neutralization reaction, but is not an
electron donor.
Unless this chain stopped by the action of an antioxidant, basically an
electron donor or receiver that gets electrons paired-up again, cell damage could occur.
This suggests that scoured cotton fabrics can be described as monopolar surfaces with a strong
electron donor capacity.
