Within this framework in a steady state plume, sequential electron acceptor utilization would theoretically produce methane at an organic-rich source and Fe(II) further downgradient, resulting in a limited zone of Fe(II) and methane overlap.
According to an internal superoxide reduction mechanism, a single oxygen binds and is reduced in two sequential electron transfer steps from the heme, using a retained superoxide intermediate.
Firstly, the soils were imaged ex situ, without any chemical processing, with sequential electron scanning of the pelletized soil samples, covering a total area of 8 × 8 mm.
The Sequential Electron Acceptor Model in 3D (SEAM3D) was used to construct a quantitative mass balance between electron donors and acceptors in this study (Waddill and Widdowson 1998).
Sequential electron transfer are the key steps which determine the efficiency of the energy conversion processes in photosynthesis.
Results also indicate that compounds 1 10 preferably interact with free radicals adopting the H atom transfer rather than the sequential electron transfer proton transfer mechanism.
Elegantly designed supramolecular triads to achieve sequential electron transfer to obtain the charge-separated states, and sequential energy transfer followed by electron transfer to mimic the photosynthetic 'antenna-reaction center' have also been developed and studied.
Analogous results have been obtained and analyzed with two other multicomponent systems undergoing multiple sequential electron transfers, namely dMeFc/Fc/TPTA and dMeFc/TTF (TPTA: tri-N-p-tolylamine; TTF: tetrathiafulvalene).
Dissolution and volatilization of oil components, their aerobic and anaerobic degradation coupled with sequential electron acceptor consumption, ingress of atmospheric O2, and the release of CH4 and CO2 from the smear zone generated by the floating oil were considered.
Sequential electron proton transfer.
Since e transfer is always accompanied by deprotonation, so it is called sequential electron proton transfer (SEPT) (Iuga et al. 2011).
