Direct Electron Transfer-Based Peroxymonosulfate Activation by Iron-Doped Manganese Oxide (δ-MnO2) and the Development of Galvanic Oxidation Processes (GOPs).

Environmental Science and Technology, 2019
Manganese oxides have been recently investigated as excellent catalysts for peroxymonosulfate (PMS) activation and the reported mechanisms are mostly forming reactive oxygen species (ROSs). This study investigated the use of an iron-doped manganese oxide,

Methanothrix enhances biogas upgrading in microbial electrolysis cell via direct electron transfer.

Bioresource Technology, 2019
Bioelectrochemical conversion of CO2 to CH4 is a promising way to increase the calorific value of biogas produced during anaerobic digestion. There are two groups of methanogens enriched in these systems, hydrogenotrophs and acetoclastic methanogens that

Direct Electron Transfer Kinetics in Horseradish Peroxidase Electrocatalysis

The Journal of Physical Chemistry B, 2006
The study of direct electron transfer between enzymes and electrodes is frequently hampered by the small fraction of adsorbed proteins that remains electrochemically active. Here, we outline a strategy to overcome this limitation, which is based on a hierarchical analysis of steady-state electrocatalytic currents and the adoption of the "binary ...

Quorum Sensing Enhances Direct Interspecies Electron Transfer in Anaerobic Methane Production.

Environmental Science and Technology
Direct interspecies electron transfer (DIET) provides an innovative way to achieve efficient methanogenesis, and this study proposes a new approach to upregulate the DIET pathway by enhancing quorum sensing (QS).

Electroinitiated Polymerization of N-Vinylcarbazole By Direct Electron Transfer

Journal of Macromolecular Science, Part A, 1990
Abstract Electroinitiated polymerization of N-vinylcarbazole has been accomplished by constant potential electrolysis. It was found that direct electron transfer from the monomer to the anode initiates the polymerization even at a potential as low as +0.95 V versus Ag−/ Ag+.

Ultrafast Energy and Electron Transfer in Photosystem I - Direct Evidence for two-branched Electron Transfer

15th International Conference on Ultrafast Phenomena, 2006
The energy and electron transfer processes in photosystem I particles carrying mutations around the primary electron acceptors have been studied. Direct evidence is provided for early electron transfer processes to occur efficiently in both cofactor branches.

Photoinduced electron transfer within ion pairs. Direct measure of the intramolecular electron transfer quenching constant

Chemical Physics Letters, 1985
Abstract The electron-transfer quenching of the luminescence emission of Ru(bpy) 3 2+ (bpy = 2,2′-bipyridine) by CoSiW 11 O 39 H 2 O 6− has been studied by steady-state and pulsed techniques. Both static and dynamic quenching were observed. The luminescence emission was found to decrease with time according to two distinct exponential decays.

Electroinitiated cationic copolymerization by direct electron transfer

Polymer, 1984
Abstract Electroinitiated cationic copolymerizations of indene-4-methoxystyrene and indene-β-bromostyrene monomer couples were investigated in dichloromethane by constant potential electrolysis. Copolymer compositions were determined by i.r. spectroscopy and reactivity ratios for the monomers were calculated according to integrated Lewis-Mayo ...

Direct Interspecies Electron Transfer in Anaerobic Digestion: A Review

2015
Direct interspecies electrons transfer (DIET) is a syntrophic metabolism in which free electrons flow from one cell to another without being shuttled by reduced molecules such as molecular hydrogen or formate. As more and more microorganisms show a capacity for electron exchange, either to export or import them, it becomes obvious that DIET is a ...
