TL;DR: In this article, a technique for the orientation, cutting and polishing of small platinum single-crystal planes is given whose angular accuracy is within 3 min. This is required for the preparation of stepped surfaces with a well-controlled step density.

TL;DR: In this paper, the coverage and pseudocapacitance behavior of over potential-deposited (OPD) H species in the cathodic H 2 evolution reaction (HER) at Pt electrodes has been determined by the potential-decay method, coupled with prior steady-state current measurements.

TL;DR: A theory for adiabatic electron transfer reactions at metal electrodes is presented in this paper, which is similar to that of the Levich and Dogonadze theory for nonadiabatic reactions, but the rate is not calculated from perturbation theory but by techniques familiar from the Anderson-Newns model for adsorption.

TL;DR: In this article, the authors describe the use of tres petites aires interfaciales liquide-liquide (<100 μm 2 ) for the purpose of constructing a fire station.

TL;DR: In this article, it was shown that polythiophen deposition occurs via a nucleation and phase growth mechanism akin to the deposition of a metal onto a foreign substrate, and it was also demostrated that H 2 O in the medium can have a strongly adverse effect on the electrodeposition process.

TL;DR: In this article, it was shown that the Pt (100) surface undergoes reconstruction due to hydrogen adsorption above 0.3 of a monolayer and the combined effect of low oxygen coverage with high hydrogen coverage induces a new type of voltammogram.

TL;DR: In this paper, an assessment of the catalytic role of foreign metal adatoms deposited at underpotentials is made with emphasis on the electrocatalysis of electrosynthetic and fuel cell reactions.

TL;DR: In this article, an analytical method, based on the adsorptive preconcentration of biomacromolecules on an electrode, the transfer of the adorbed layer into a new medium (containing background electrolyte) and subsequent voltammetric analysis, is proposed.

TL;DR: In this article, the residual current, obtained in supporting electrolyte solution, is digitally subtracted from the voltammogram obtained in the presence of the electroactive species, facilitated by conducting the whole experiment in a flow injection apparatus so that the electrode remains in solution while the two voltammograms are obtained.

TL;DR: A detailed study of the voltammetry curves of Pt (111) prepared by the flame method has provided strong evidence that the anomalous features reported originally by Clavilier et al., are associated with the specific adsorption of anions rather than hydrogen adsoreption as discussed by the authors.

TL;DR: In this article, the infrared absorption intensities of linear CO(a) derived from CO, CH3OH and HCOOH, respectively, on a platinum electrode in 0.5 M H2SO4 were determined as a function of the total adsorbate coverage.

TL;DR: In this article, the authors used differential pulse cathodic stripping voltammetry (DPCSV) followed by adsorptive collection of complexes with 8-hydroxyquinoline (oxine) onto a hanging mercury drop electrode (HMDE) to determine simultaneously copper, lead and cadmium in seawater.

TL;DR: In this article, the number of electrons involved in the redox mechanism of PANi is measured by multiple potential step chronocoulometry (PSC), and the kinetics of the charge transfer and the cross reaction rate at the polymer/solution interface are estimated and measured by using Levich's direct and inverse criteria.

TL;DR: In this paper, a pH 42, 2 M Na 2 SO 4 carbon dioxide saturated solution was used for open circuit reduction of carbon dioxide. But the results showed that the molybdenum electrodes showed no detectable moly bdenum dioxide on the surface indicating that the electrodes are cathodically protected during electrolysis.

TL;DR: In this paper, the effects of adsorbed anions such as NO−3 and Cl− are compared with those obtained with a special vacuum transfer system, and several of the factors controlling hydrogen adsorption on Pt and particularly anion effects are discussed.

TL;DR: In this article, cyclic voltammograms for 1-iododecane, 1-brommodecane and 2 -bromooctane were used to detect the formation of carbanions.

TL;DR: In this paper, the use of surface modified metallic and semiconducting electrodes for the electrocatalytic and photo-electrocatalysistic reduction of CO 2 was demonstrated using electropolymerized films of [Re(CO) 3 (v-bpy) Cl] [4-vinyl, 4′-methyl-2,2.2′bipyridine].

TL;DR: In this paper, the development of a sensitive electrochemical assay for low levels of hydrogen peroxide is described, based on the enzymic reduction of substrate (H2O2) by peroxidase and subsequent electron transfer from a gold or pyrolytic graphite electrode to the enzyme via a redox mediator.

TL;DR: In this paper, the surface properties of RuO2 + IrO2 mixed oxide layers deposited on Ti by thermal decomposition of the corresponding chlorides in aqueous solutions have been investigated by means of cyclic voltammetry and ex situ UHV (AES and XPS) techniques.

TL;DR: In this paper, ascorbic acid, dihydroxyphenylacetic acid, and dopamine were compared at polypyrrole-coated glassy carbon and naked glassy polynodes, and it was shown that the electrochemical reversibility differences for these substances are to some degree result of electrostatic interactions between the anionic solutes, or anionic reaction intermediates, and anionic functional groups on carbon or cationic fixed sites in oxidized poly pyrrole.

TL;DR: In this article, six commercially available and six especially designed amorphous metals have been investigated by steadystate polarization measurements and cyclic voltammetry to evaluate their suitability as electrocatalysts for hydrogen and oxygen evolution in alkaline solution.

TL;DR: In this article, analytical solutions for diffusion-migration impedances of four systems that can serve as a basis for analysis of redox membrane-coated electrode and electrolyte-bathed membrane cells are presented.
