TL;DR: In this paper, the chronoamperometric current at a stationary finite disk electrode is studied using both analytical and digital simulation techniques, and the exact long-time expansion of the current is obtained and its short-time behavior is considered.

TL;DR: In this paper, a new theory was proposed for the potentiostatic current maximum which leads to more reliable values of the nuclear number density and to a better distinction between instantaneous and progressive nucleation.

TL;DR: In this paper, a kinetic model describing the catalytic activity of redox polymer film electrodes is presented and discussed for reaction schemes in which the primary reaction between the active form of the catalyst and the substrate is the rate-determining step.

TL;DR: In this article, an analysis of the ability of nonlinear complex least squares fitting to yield useful estimates of parameter values occurring in equivalent Voigt circuits is made, and three-dimensional perspective plots are presented which show the full frequency response of either impedance or admittance data.

TL;DR: In this article, a series of N-substituted polymer films have been synthesized and the initial characterization of these polymeric films when in the oxidized form indicates that the degree of oxidation of the polymer and the conductivity is reduced with the introduction of Nalkyl substituents.

TL;DR: In this article, a cobalt electrode in base to repetitive triangular potential sweeps over the range 0.2 V(RHE) resulted in the formation of a thick hydrous oxide film.

TL;DR: In this article, the anodic formation of oxide layers on perchloric acid and their cathodic reduction have been investigated using cyclic voltammetry and linear sweep polarization, and it is assumed that slow structural changes of the oxide layer occur.

TL;DR: In this article, the capacity-potential curves observed at the single crystal gold-aqueous solution interphases are investigated for the five faces (100, (110), (111), (311), (212), and (210) which should have extreme electrochemical behaviour.

TL;DR: In this paper, a procedure is described whereby thin films of an alkylamine-siloxane polymer can be formed on Pt electrode surfaces, and electrocatalytic reaction of trapped ferrocyanide ions can be stably observed.

TL;DR: In this article, cyclic and rotating disk voltammetry were used to examine the kinetics of the catalyzed reactions and mechanistic schemes were proposed to account for the observed kinetics.

TL;DR: In this article, a mechanistic investigation of the electrochemical oxidation of methanol was worked out in alkaline medium in order to interpret the effect of some foreign metal ad-atoms (Pb, Bi, Cd, Tl) on the electrocatalytic activity of platinum.

TL;DR: In this article, the authors investigated the electron transfer cross-reaction between the solute complex and poly-[Ru(vbpy) 3]2+ sites generated in the film at sufficiently positive potentials.

TL;DR: In this paper, the electrochemical properties of thin films of metal phthalocyanines on conducting substrates are investigated and a film electrode model is proposed based on an irreversible charge transfer step.

TL;DR: In this article, a kinetic description of systems in which the cross-exchange equilibrium constant may take any value is presented, where the parameters of the system are specified and their role in the context of stationary techniques such as rotating disk voltammetry.

TL;DR: In this article, the phenomenological theory of hemispherical growth is generalised to time-dependent nucleation and growth rates, and expressions for small and large time behaviour and peak characteristics of potentiostatic transients are discussed.

TL;DR: In this article, the rate of diffusion to ensembles of microelectrodes is calculated by digital simulation, based on the explicit finite-difference technique, and the results are compared with previous calculations based on analytical solutions, which were derived on the basis of different approximations.

TL;DR: In this paper, the formation of weakly bound hydrogen on a polycrystalline platinum electrode was found to be associated with the appearance of a number of IR absorption bands in the range 1.6-7.5 μm.

TL;DR: In this paper, a study of the electrochemical nucleation of silver on vitreous carbon from aqueous solutions of silver nitrate is presented, where the nucleation is shown to be progressive and mass transferred controlled.

TL;DR: In this article, two viologen polymers are described and formed in films on Pt. Au. C and SnO2 electrodes, which are used to catalyze the reduction of dibromodiphenylethane.

TL;DR: A greatly improved voltaic cell, based on the Kenrick cell and using a mercury jet reference electrode, has been made and tested as discussed by the authors, which is capable of measuring a compensating potential difference (cpd) to = 0.1 mV or better, a precision comparable with that obtainable with wellbehaved galvanic cells.

TL;DR: In this article, the influence of six different foreign metal ad-atoms (Cd, Re, Pb, Cu, Bi, Tl) on the electrocatalytic activity of a platinum-based electrode was investigated in the case of the oxidation of ethylene-glycol in acid medium.

TL;DR: In this article, the potential jump and optical absorbance have been measured on thionine-coated electrodes and it was shown that at pH 1.3 the characteristic diffusion time varies with the size of the anion present in the electrolyte, showing that diffusion of the counter ions is the ratelimiting process.

TL;DR: In this paper, an attempt is made to clarify the situation by testing physical and electrochemical data using different approaches to the concept of hydrophilicity, and the validity different correlations between the surface potential of water molecules at the interface and various parameters is discussed for sp metals.
