Study on the direct electron transfer process of superoxide dismutase

Bioelectrochemistry and Bioenergetics, 1999
The electron transfer process of biological important species, superoxide dismutase (SOD), was studied using cyclic voltammetric method at different conditions. The rate of electron transfer process of SOD at conventional bare gold electrode was very low. Different methods were used to enhance the rate of this process. Gold microdisk electrode and gold

Directional electron transfer: conformational interconversions and their effects on observed electron-transfer rate constants

Journal of the American Chemical Society, 1989
The interaction between conformation changes and electron-transfer rates is considered for systems containing two redox centers. The effect of conformation changes on the free-energy barrier to intramolecular electron transfer is examined. Unstable conformers R* of the reactant (or P* of the product) that are either more (low-{lambda} intermediates) or

Electron Transfer Principles In Amperometric Biosensors: Direct Electron Transfer Between Enzymes And An Electrode

Proceedings of the International Solid-State Sensors and Actuators Conference - TRANSDUCERS '95, 2005
The development of reagentless biosensors is of fundamental importance for the improvement of the sensor characteristics. In this respect, direct electrical communication between the enzyme and an electrode surface has to be established. We could demonstrate that in the case of biocatalysts catalyzing the same redox process (H/sub 2/O/sub 2/ reduction)

Direct determination of the effective electronic coupling in electron-transfer problems

The Journal of Physical Chemistry, 1993
The theory of effective Hamiltonians is used to calculate the effective electronic coupling between the two nearly degenerate A + -L-B and A-L-B + structures in electron-transfer problems. A procedure is proposed to include the leading contributions of electron correlation to the effective coupling, either in a second-order approach or through a ...

Direct observation of transferred-electron effect in GaN

Applied Physics Letters, 1995
We report the direct observation of transferred-electron effect in unintentionally doped GaN epilayers grown by metalorganic chemical vapor deposition. The negative differential resistivity (NDR) was observed from the current-electric field characteristics in GaN using a metal-semiconductor-metal (M-S-M) system. The threshold field for the onset of NDR

Syntrophy Goes Electric: Direct Interspecies Electron Transfer

Annual Review of Microbiology, 2017
Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for DIET have primarily been studied in defined cocultures in which Geobacter species are one of the DIET partners. Electrically conductive pili (e-pili) can be

Electroinitiated polymerization of acrylamide by direct electron transfer

Journal of Polymer Science Part A: Polymer Chemistry, 1989
AbstractElectroinitiated polymerization of acrylamide was carried out in acetonitrile–tetrabutylammonium fluoroborate by electrolytic reduction of monomer. It was shown by cyclic voltammetry that direct electron transfer from the cathode to the monomer can be achieved in this solvent–electrolyte system.

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 ...
