Facilitated proton transfer via water autoprotolysis-electron transfer coupled reactions at thick-film modified electrodes
(Pergamon-Elsevier Science Ltd, 2020-07)
We present the derivation of a general mathematical model for facilitated proton transfer (FPT) reactions across a liquid|liquid (L|L) interface assisted by a protonatable neutral weak base at a thick organic film modified ...
Facilitated proton transfer-electron transfer coupled reactions at thick-film modified electrodes
(Pergamon-Elsevier Science Ltd, 2017-12)
The theory of cyclic voltammetry of facilitated proton transfer-electron transfer coupled reactions (FPT-ET reactions) in a thick organic film modified electrode is developed. It is shown that the coupling between the ...
An integrated theoretical-experimental approach to understand facilitated proton transfer-electron transfer coupled reactions at thick-film modified electrodes
(Pergamon-Elsevier Science Ltd, 2018-09)
The main purpose of the current work is to generalize the analytical model for the facilitated proton transfer-electron transfer coupled reactions at thick organic film-modified electrodes, including ion pairing in the ...
Modulation of Functional Features in Electron Transferring Metalloproteins
(Centro de Estudios sobre Ciencia, Desarrollo y Educación Superior, 2020-03)
Electron transferring metalloproteins are typically implicated in shuttling electrons between energy transduction chains membrane complexes, such as in (aerobic and anaerobic) respiration and photosynthesis, among other ...
Photoinduced electron-transfer cycloreversion of thietanes: The role of ion-molecule complexes
(American Chemical Society, 2010-04)
Cycloreversion (CR) of thietane radical cations leads to formation of thiobenzophenone and the corresponding alkenes, eventually followed by secondary [4 + 2] cycloaddition. Final product distribution depends on the ability ...
The role of protein dynamics and thermal fluctuations in regulating cytochrome c/cytochrome c oxidase electron transfer
(Elsevier Science, 2014-02)
In this overview we present recent combined electrochemical, spectroelectrochemical, spectroscopic and computational studies from our group on the electron transfer reactions of cytochrome c and of the primary electron ...
Charge accumulation and electron transfer kinetics in Geobacter sulfurreducens biofilms
(Royal Society of Chemistry, 2012-03)
Electroactive bacteria can use a polarized electrode as final electron acceptor, allowing the use of electrochemical techniques for a very accurate quantification of its respiration rate. Biofilm cell respiration has been ...
Wave-Function Symmetry Control of Electron-Transfer Pathways within a Charge-Transfer Chromophore
(American Chemical Society, 2020-09)
Despite a diverse manifold of excited states available, it is generally accepted that the photoinduced reactivity of charge-transfer chromophores involves only the lowest-energy excited state. Shining a visible-light laser ...
Electron transfer pathways from quantum dynamics simulations
(American Institute of Physic, 2020-12)
This work explores the possibility of simulating an electron transfer process between a donor and an acceptor in real time using time-dependent density functional theory electron dynamics. To achieve this objective, a ...
Comparison of the Kinetics of Electron Transfer in the Diffusion Limit for the Singlet and Triplet Quenching of Eosin Y by Quinones
(Wiley, 2013-06)
Electron transfer (ET) rate constants were determined by means of lifetime measurements for the fluorescence quenching and by laser flash photolysis for the triplet quenching of the dye eosin Y by benzoquinones in acetonitrile. ...
