Direct Electron Transfer Coordinated by Oxygen Vacancies Boosts Selective Nitrate Reduction to N2 on a Co-CuOx Electroactive Filter.

Environmental Science and Technology, 2022
Atomic hydrogen (H*) is used as an important mediator for electrochemical nitrate reduction; however, the Faradaic efficiency (FE) and selective reduction to N2 are likely compromised due to the side reactions (e.g., ammonia generation and hydrogen ...

Theory of Directed Electronic Energy Transfer

Journal of Fluorescence, 2006
The migration of electronic energy between molecules or chromophores in molecular solids is a well-studied phenomenon. The ability to exert control over the directionality of this transfer, by a variety of methods involving applied electrical or optical fields, holds promise for advances in fields including nanoelectronics and energy harvesting ...

Direct electron transfer effect biosensors

Biosensors and Bioelectronics, 1996
A review of biosensors based on the direct electron transfer effect is carried out in this work. Different redox enzymes and proteins using the direct electron transport mechanism for electrocatalytical processes are described. The tunneling of electrons as a possible explanation of the direct electron transfer effect is also discussed.

Biological electron transfer: progress and future directions

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1991
The rich diversity among bacterial cytochromes has played a key role in the development of our understanding of biological electron transfer. Although studies to date have allowed the elucidation of the contributions of driving force, electrostatics interactions and surface topology to electron transfer kinetics in collision-dependent reactions, much ...
