Stark emission spectroscopy, transient DC photoconductivity (TDCP), and ground-state dipole moment measurements have been used to evaluate charge transfer (CT) within various (X(2)-bipyridine)Re(I)(CO)(3)Cl complexes following (3)MLCT excited-state formation. The Stark technique reports on vector differences between ground-state (mu(g)) and excited-state (mu(e)) dipole moments, while TDCP, when...
Diameter dependent electron donor behavior of (6,5)- and (7,6)-enriched semiconducting SWCNT is proved by constructing supramolecular nanohybrids with pyrene functionalized electron acceptor, fullerene, and the subsequent photocatalytic/ photoelectrochemical processes.
Within an oligonucleotide duplex, excess electron transfer from a excited 5-(pyren-1-yl)uridine through an internal stacked phenanthrenyl pair to 5-bromouridine as an electron acceptor was observed.
The mechanisms by which Geobacter sulfurreducens transfers electrons through relatively thick (>50 microm) biofilms to electrodes acting as a sole electron acceptor were investigated. Biofilms of Geobacter sulfurreducens were grown either in flow-through systems with graphite anodes as the electron acceptor or on the same graphite surface, but with fumarate as the sole electron acceptor. Fumara...
Most inanimate systems are build of closed-shell molecules in which electrons lack excitability and mobility. These electrons can be rendered reactive and mobile by taking out some of them, desaturating the system electronically. Single electrons can be taken out of molecules by transfer to an external acceptor, creating two radicals that form a biradical having no net charge. The living state ...
iron reducing bacteria (irb) are one of the most applicable microorganisms in various industrial and environmental activities. these bacteria play a main role in the natural iron transformation. they act in a reverse metabolic pathway in contrast to iron oxidizing bacteria. in the anaerobic conditions irb are capable to use ferric ion as the final electron acceptor and reduce fe3+ to fe2+. what...
