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 ...
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 ...
Ion transfer across liquid|liquid interface under forced hydrodynamic conditions. I: Digital simulations
(Elsevier Science Sa, 2012-02)
In this paper, we present the general equations for a model that describes ion transfer reactions across the oil|water interface assisted by a ligand, under forced hydrodynamic conditions. Our analysis is mainly focused ...
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 ...
Effect of ligand protonation on the facilitated ion transfer reactions across oil|water interfaces. V. Applications of forced hydrodynamic conditions
(Elsevier Science Sa, 2016-03-05)
Hydrodynamic forced conditions applied to the aqueous or the organic phase during a potential sweep can be used to elucidate themechanisms of ion transfer across liquid|liquid interfaces. The aimof this study is to confirm ...
Effect of aggregation on the simple ion transfer across oil|water interfaces
(Elsevier Science SA, 2020-12)
The theory of cyclic voltammetry of simple ion transfer across a liquid|liquid (L|L) interface including the effect of aggregation is developed. We focus on two different situations: ion transfer followed by an aggregation ...
Reactions of halonorbornane and oxo-substituted derivatives with different anions by the electron transfer mechanism; redox catalysis in stabilized radicals
(Royal Society of Chemistry, 2010-09)
Reactions of 2-bromo-, 2-chloronorbornane, 3-chloronorbornan-2-one and 3-bromocamphor with Me3Sn-, Ph2P- or PhS- ions were studied by an SRN1 mechanism in liquid ammonia or DMSO. The results show that substrates having a ...
Transport of molybdenum with Alamine 336 using supported liquid membrane
(Elsevier Science, 2004-03)
The appropriate experimental conditions of Mo(VI) ion transport across a supported liquid membrane containing Alamine 336 as the mobile carrier dissolved in kerosene solvent have been investigated. The molybdenum flux has ...
