TL;DR: In this article, a fixed anionic site ion exchange model has been used to derive long-lived transient potential distance-time profiles of ideal (surface film-free) glass membranes, and the currentvoltage-time curve applicable at short times for two mobile species has also been derived, and serves as a basis for the theory of membrane impedance.

TL;DR: In this paper, a mechanism of oxidation of cystine with participation of the surface oxide has been proposed, which is almost the same as the potential range of surface oxide formation.

TL;DR: In this article, the authors measured the time constant of glass electrodes in water and organic solvents at varying proton activities and derived an expression relating experimental data to electrode kinetic quantities.

TL;DR: In this article, the initial potential of the oxidation arrest in anodic charging curves depends upon temperature in nearly the same way for type-I species of adsorbed carbon monoxide and for reduced carbon dioxide, but in a different way for the chemisorbed carbons formed from methanol.

TL;DR: In this paper, it is shown that the transfer coefficient, α, describes the change in the energy barrier as the potential changes, and not any property of the barrier at a particular potential.

TL;DR: In this article, the same species is absorbed in all the cases studied and that it has the composition HCO, and it is probable that COOH radicals are also present to a certain extent.

TL;DR: In this paper, the In3+/In(Hg) system in KSCN and KCl solutions has been investigated using both d.c. and a.m. measurements.
