TL;DR: In this article, the diffusion effects induced by partial blocking of an electrode surface toward electron transfer are analyzed in the case where the blocking film is sprinkled with a large number of microscopic, active sites.

TL;DR: The chronoabsorptometric results show that polypyrrole film grows linearly with time t and not t 1/2 as mentioned in this paper, which is consistent with the slow step in the growth process being a radical coupling step and not the diffusion of pyrrole to the electrode surface.

TL;DR: In this article, the voltammetric response of some nucleation/growth processes is derived, for the early stages of crystal growth where intercrystal collisions are statistically improbable, and the theory is formulated for both interfacial and diffusional control of the crystal growth kinetics.

TL;DR: In this article, a complete review of double-layer data obtained with single-crystal faces of sp metals is presented, including seven tables summarizing all data obtained to date and 158 references.

TL;DR: In this article, a new understanding of the nature of electrode reactions at graphite paste electrodes has been obtained by studying electron-transfer rates of redox systems under conditions of carefully controlled electrode composition and pretreatment.

TL;DR: In this paper, a selective permeability of polymers derived by electrochemical polymerization from phenol and amino-aromatic compounds to the various oxidation-reduction species dissolved in the solution was investigated by means of hydrodynamic voltammetry at a rotating disk electrode.

TL;DR: In this article, the electrocatalytic oxidation of CO, HCOOH and CH3OH is compared on Pt(100), Pt(110) and Pt(111) single crystals.

TL;DR: In this article, the authors compare the qualitative results given by EMIRS to the quantitative determination of the adsorbed layer, as obtained by conventional electrochemistry, and show that the so-called CO species, which are detected by EqS during the chemisorption of formic acid on a Pt electrode, are the dominant species over a large potential range during which the coverage reaches a maximum and constant value.

TL;DR: In this paper, the atomic-scale structural changes induced by potentiodynamic cycling of a well-characterized Pt(100) surface in 0.3 M aqueous HF were identified.

TL;DR: In this paper, a theoretical study of the 2 e, 2H+ reaction is presented for a surface reaction (adsorbed species, Langmuir isotherm or monolayer-modified electrode), or for a heterogeneous electrochemical reaction with protonations taking place in solution near the electrode.

TL;DR: In this article, Damjanovic et al. modified the rotating ringdisc electrode method to calculate most of the rate constants for the intermediate formation of H2O2 in the electroreduction of O2 to H 2O.

TL;DR: In this article, subtractively normalized interfacial Fourier transform infrared spectroscopy applied to the in situ study of the electrode-electrolyte solution interphase is presented, which is used to obtain difference infrared spectra of electrogenerated intermediates and species adsorbed at the electrode surface.

TL;DR: In this article, a comparison of apparent diffusion coefficients for the oxidized and reduced forms of various ionically diffusing redox couples shows that the ratio of these diffusion coefficients is critically dependent on the nature of the diffusing ion.

TL;DR: A detailed voltammetric and coulometric study of both the conditions for electrodeposition from ferric ferricyanide solution, of Prussian Blue film on Pt, and of potential sweeps of the deposited film in KCl solution alone is reported in this article.

TL;DR: In this article, the frequency factor for outer-sphere electrochemical reactions based on a collisional model is compared with an alternative "encounter preequilibrium" treatment whereby A n e is determined by the effective frequency of surmounting the free energy barrier within a previously assembled precursor state.

TL;DR: In this paper, a square-wave potential anodizing procedure to obtain noble metal surfaces with both a controlled roughness and a reproducible electrochemical response is presented, where the influence of the characteristics of the square wave potential perturbation are systematically studied.

TL;DR: In this paper, a small amount of Fe(CN)64−/σOH−⋍105 was used to suppress the transient effects of hydroxyl radicals stabilised at iron sites.

TL;DR: In this paper, the thermodynamic surface excess of water at several organic solvents-aqueous solution interfaces has been determined for different salt solutions and the coordinates of pendant drops were measured with a video image digitising technique and the interfacial tension was calculated using a simple computational approach.

TL;DR: In this paper, the reduction of anthracene in dimethylformamide in the presence of phenol was investigated, and it was shown that this reaction followed a "DISP1" limiting mechanism which involves the protonation of the anion radical as the rate-determining step followed by homogeneous electron transfer between the radical and the proptonated anion, yielding the monohydrogenated anions which is itself rapidly and irreversibly protonated into the final dehydrogenated product.

TL;DR: In this paper, a microscopic model for the metal-solution interface is presented, which, for the first time, includes both a nonideal treatment of the metal and a molecular model for solution side.

TL;DR: In this paper, an n-Si electrode that has been covered with an oxide layer shows a peak of anodic current a short time after it is immersed in a HF solution at pH 4.9.

TL;DR: In this article, the authors discussed the role of electrical double layers around colloid particles and their role in low-frequency dielectric dispersion e(ω) and provided conditions under which these two mechanisms are operative.

TL;DR: In this paper, an electrochemical treatment of the former electrodes was proposed, involving the repetitive cycling of the electrode potential within a negative range, and a steady value of the apparent standard rate constant was obtained which was not very different from the values obtained on mercury and on glassy carbon.

TL;DR: In this article, the electrochemical pretreatment of glassy carbon electrodes over the range from 1.8 to −0.8 V (vs. Ag/AgCl) at pH 7.0 produces electrode-active groups, evidently, of quinoidal structure that are oxidized-reduced with ks=0.4 − 0.8 s−1 at 0.

TL;DR: In this paper, anodic corrosion and O2-evolution on Ru and Ir electrodes in 0.5 M H2SO4 was investigated using X-ray photoelectron spectroscopy.
