TL;DR: In this article, the linear potential sweep voltammetry for a simple redox system in the case of a space distributed redox modified electrode (redox polymer electrode, or adsorption of an electroactive substance in several layers) is established on the basis of the model discussed in Part I.

TL;DR: In this article, a multilayer model for the study of space distributed redox modified electrodes (redox polymer electrodes, or adsorption of an electroactive substance in several layers) is described and discussed in detail.

TL;DR: In this paper, the theory of homogeneous redox catalysis in the context of cyclic voltammetry is presented for the EC reaction scheme, i.e., the simplest of the mechanisms in which the initial electron-transfer process is followed by chemical reaction.

TL;DR: In this paper, a model for the cyclic voltammetric behavior of polymeric films on electrode surfaces was proposed, which incorporates non-equivalent redox sites with interconversion between such sites, electron-transfer kinetics at substrate/film interface and diffusion within the film.

TL;DR: In this paper, the linear potential sweep voltammogram is derived for any degree of reversibility of the electrochemical reaction for a surface redox system, when interactions between the adsorbed molecules are present.

TL;DR: In this paper, the anodic oxidation of various monosubstituted aromatic amines has been grafted on Pt electrodes in a CH3CN−NaClO4-pyridine medium.

TL;DR: In this paper, an ECE mechanism was proposed as the main reaction with dimerization of the NAD radical or a disproportionation as alternative routes to NAD+ or NADH containing solutions.

TL;DR: The Galvani potential difference at the interface of two immiscible electrolyte solutions (ITIES), Δ α βϕ, can be determined, when concentrations, activity coefficients, standard Gibbs transfer energies of all ions, which are present in the system, volumes of each phase and temperature are known as discussed by the authors.

TL;DR: In this article, the electrochemical properties of amino acids containing no sulfur atoms have been investigated using stationary or rotating solid electrodes such as Au and vitreous carbon, and the first of the second electrochemical oxidation pathway can be favored.

TL;DR: In this article, the analysis of homogeneous redox catalysis of an EC electrochemical reaction is greatly simplified if the stationary-state assumption can be made for species B. The polarization problem has been numerically solved for these two limiting cases as well as for the transition between them in the context of stationary or quasi-stationary electrochemical methods such as rotating disc voltammetry or classical polarography.

TL;DR: Electron-micrographs of thymocytes subjected to field pulses of various strengths and durations show that the pulse length is a critical factor for the reversibility of the field induced effects in the cell.

TL;DR: In this article, an investigation of cathodic oxygen reduction in pure and contaminated solutions using the ringdisc technique showed that on Pt and Ag under clean conditions the four-electron reduction of O 2 is operative, only small amounts of H 2 O 2 are produced In contaminated solution, a decrease of the catalytically active surface of Pt is observed, but on Ag the H 2O 2 formation significantly increases.

TL;DR: In this paper, a general mechanism for O2 electrocatalysis is proposed based on results obtained for dissolved, adsorbed and polymercoated porphyrin, which can be controlled by changing the surface coverage of the porphrin.

TL;DR: In this article, the first stages of the anodic oxidation of polycrystalline copper electrodes in NaOH solutions were studied by potential sweep voltammetry and ellipsometry, and the formation of bulk Cu2O was found to be preceded by electrosorption of oxygen species.

TL;DR: In this paper, the catalytic effect of Pb2+ with AuOH surface on gold was studied in more detail as most illustrative, and the mechanism of HO2− formation is uncertain, while its reduction most probably involves a direct process.

TL;DR: In this paper, the electrochemical behavior of functionalized polystyrene-coated electrodes shows a marked dependence on the nature of the electrolyte ions, and it is shown that changes in polymer film volume and morphology accompany electrochemical oxidation.
