TL;DR: In this article, a method of characterising the electrical properties of polycrystalline electrolytes is described which enables grain boundary (intergranular) and bulk (intragranular) impedances to be separated and identified, by reference to an equivalent circuit which contains a series array of parallel RC elements.

TL;DR: In this article, a diagnostic criterion was developed which allowed a distinction to be made between the two main possible reaction paths in electroreduction of oxygen, and applied to the results obtained in the rotating ring-disc electrode system on gold in alkaline solutions, indicating the absence of the direct four-electron reduction.

TL;DR: In this article, the rate of the hexacyanoferrate redox system shows a first order dependence on the concentration of the cationic component of the supporting electrolyte.

TL;DR: In this article, the first part of a comprehensive treatise on high energy batteries working with lithium anodes and aprotic solvents is presented, as well as the problems connected with their application.

TL;DR: In this article, the authors measured the complex impedance of the interface between a single crystal or a sintered disc of β alumina and a gold electrode in the frequency range 1−104 Hz.

TL;DR: In this article, the second part of a review on high energy density lithium cells, deals with the cathode materials used in such systems and with complete cells, and the fundamental problems connected with these cathodes are pointed out and demonstrated in the cases of the silver and copper halides.

TL;DR: In this paper, a series of discrete copper sulphide phases have been identified during the anodic oxidation of Cu2S to CuS. Their free energies have been calculated from the electrode potentials and compared with other work.

TL;DR: In this article, the authors used potential step techniques to study the mechanism of the anodic oxidation of carbon monoxide adsorbed onto a smooth platinum surface and showed that the experimental data are consistent with a "reactant pair" mechanism similar to that proposed by Gilman.

TL;DR: In this article, thin layer electrochemistry was combined with low-energy electron diffraction (1.e.l.d.) in order to study the relationship between electrochemical reactivity and the structure of the electrode surface with an adsorbed layer of electrolyte.

TL;DR: In this article, it has been established that qualitative agreement between the experimental data and either the classical or the atomistic model cannot be considered as a reliable criterion for the validity of either of the two theoretical concepts.

TL;DR: In this article, the authors studied the impedance characteristics of cell systems with and without Pt-paint and found that the impedance is characterized by a constant phase angle (CPA), which is due to highly inhomogeneous current distribution effects.

TL;DR: It has been long known that the codeposition of metals as alloys can often lead to reduction of the less noble coponent ion at potentials more positive than can be predicted from thermodynamic considerations only as discussed by the authors.

TL;DR: In this paper, the electron transfer rate of 1,4-benzoquinone in DMF at platinum, gold and mercury electrodes was measured by cyclic voltammetry and found to be much larger than reported earlier.

TL;DR: In this paper, the polarographic behavior of tetra-n-butylammonium hexacyanoferrate (II) has been studied in N-methylpyrrolidinone, N-N-dimethylformamide, acetonitrile, dimethylsulphoxide, N,Ndimethylthioformamide and 1,2-dichloroethane.

TL;DR: In this paper, the cathodic decomposition of propylene carbonate was investigated and the reaction products were propene and carbonate, and an interpretation of the observed effects due to reactions of impurities such as water can be excluded.

TL;DR: In this article, a theoretical study of a two-step reversible electrochemical reaction OPR is made in thin layer linear potential sweep voltammetry when O, P and R can undergo one or several of the following irreversible chemical reactions: P→Z, R→Z and O+R→Z.

TL;DR: In this article, the electrooxidation of formaldehyde and methanol has been studied on a number of binary platinum electrocatalysts, which comprised mixed electrodeposits of Pt with Sb, As, Bi, Hg, Re, Te or Sn and a range of homogeneous Pt-Rh alloys of different surface compositions.

TL;DR: In this article, the point of zero charge (p.z.c.) and the isoelectric point (i.p.) of Al 2 O 3 and TiO 2 in LiCl, KCl and CaCl 2 solutions were compared.

TL;DR: The formation of the adsorbed layer, however, is preceded by bulk deposition as discussed by the authors, and with the ionization of the bulk metal the formation of a strongly adorbed species is begun.

TL;DR: In this article, the spectral properties of the anion radicals and dianions of a series of 1,4-benzoquinones, 1, 4-naphthoquinones and 9,10-anthraquinones have been obtained.

TL;DR: In this paper, a growth model based on rate-determining nucleation was proposed for interpreting the observed continual growth during potential step transients in the oxide region, and for clarifying other aspects of hysteresis behaviour.

TL;DR: In this article, the reduction of benzil has been studied in N,N-dimethylformamide (DMF), dimethyl-sulfoxide (DMSO) and acetonitrile (AN) in the presence of group IA and IIA metal ions.

TL;DR: In this article, the electrochemical reduction of oxygen in acid solution was studied at rotated electrodes of eight different pyrite specimens which were electrically characterized and included n-type, ntype metallic and p-type examples.
