Electron donors for biological sulfate reduction
Biotechnology Advances, 2007Biological sulfate reduction is widely used for treating sulfate-containing wastewaters from industries such as mining, tannery, pulp and paper, and textiles. In biological reduction, sulfate is converted to hydrogen sulfide as the end product. The process is, therefore, ideally suited for treating metal-containing wastewater from which heavy metals ...

Electron donor-acceptor couples
International Reviews in Physical Chemistry, 1995Abstract Two-state small-polaron models commonly used to describe an electron donor—acceptor pair are reviewed. From such models, one obtains a one-dimensional model potential. In the homonuclear case, the reaction coordinate for the potential is an antisymmetric vibrational mode.

Donor-Based Single Electron Pumps with Tunable Donor Binding Energy
Nano Letters, 2012We report on single electron pumping via a tunable number of individual donors. We use a device that essentially consists of a silicon nanowire with local arsenic implantation between a set of fine gates. A temperature-dependent characterization of the pumped current allows us to extract the ionization energy of a single arsenic donor.

Donor-Substituted Diphenylacetylene Derivatives Act as Electron Donors and Acceptors
The Journal of Organic Chemistry, 2011Despite the predominant electron donor character of p-phenylenediamine, our studies on extended p-phenylenediamine derivatives show that they can not only be chemically oxidized, giving well-known Wurster-type radical cations, but also be chemically reduced, giving radical anions.

Ampicillin serves as an electron donor
International Journal of Biochemistry, 19901. The effect of ampicillin on cytochrome c reduction and on the superoxide production of human neutrophils stimulated by phorbol myristate acetate (PMA) was investigated. 2. Ampicillin did not stimulate the superoxide production of intact (resting) neutrophils and not amplify the superoxide production of neutrophils stimulated by phorbol myristate ...

Purple Bacteria: Electron Acceptors and Donors
2013ABSTRACT: Purple bacteria form a heterogeneous group of microorganisms capable of growing under anoxic conditions by anoxygenic photosynthesis. They can be divided in purple non-sulfur bacteria, which are able to grow both phototrophically and in darkness, and purple sulfur bacteria, all of them capable to grow in the light but only few of them in the ...

Diazadithiafulvalenes as electron donor reagents
Journal of the Chemical Society, Perkin Transactions 1, 1999Diazadithiafulvalenes act as excellent electron donors to arenediazonium salts. The diazadithiafulvalenium radical cations trap primary carbon radicals successfully. However, the diazadithiafulvalenium salts which form, undergo rapid ring fragmentation in contrast to their tetrathia counterparts.

Octabutoxyphthalocyanine, a new electron donor
J. Chem. Soc., Dalton Trans., 1988The preparation of the 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine zinc complex (1) is described. The electron-donating groups influence the properties of the compound. The oxidation–reduction potentials studied by cyclic voltammetry in solution shift by ca.

Metallocenes, Strong Electron Donors
2003For many years it was puzzling that metal atoms, which were not considered good Lewis acids, could form adducts with CO, considered to be a poor donor toward most Lewis acids. An example is the hexacarbonylchromium, Cr(CO)6. On the other hand, it was stressed that chromium, having 24 electrons, by accepting 6x2 electrons from 6 CO molecules, will fill ...
