Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Kinetics of the oxygen evolution reaction on NiSn electrodes in alkaline solutions
(Elsevier Science Sa, Lausanne, 2015)
In order to examine the intrinsic catalytic activity and durability of the electrodeposited NiSn alloy electrodes and the electrodeposited Ni as a reference electrode material for the oxygen evolution reaction (OER) in ...
Kinetic study of formic acid oxidation on carbon-supported platinum electrocatalyst
(Elsevier Science Sa, Lausanne, 2005)
Oxidation of formic acid on the platinum catalyst supported on high area carbon was investigated by potent iodynamic and quasi-steady-state polarization measurements. It was found that the poisoning of the reaction occurred ...
Electrocatalysis by nanoparticles - Oxygen reduction on Ebonex/Pt electrode
(Elsevier, 2006)
The oxygen reduction reaction was studied in 0.5 mol dm-3 HClO4 solution on an electrode based on Ebonex-supported platinum electrocatalyst applied on rotation Au disk electrode (Au/Ebonex/Pt). Pt catalyst was prepared by ...
Oxygen reduction on iron. Part VII. Temperature dependence of oxygen reduction on passivated iron in alkaline solutions
(Elsevier Science Sa, Lausanne, 1995)
The temperature dependence of the kinetics of O2 reduction was studied on passivated Fe in NaOH solutions having a concentration ranging from 0.010 to 1.0 mol dm-3 and in the temperature range from 2 to 42 °C. The apparent ...
Voltammetric behavior of solifenacin succinate on gold, glassy carbon and boron-doped diamond electrodes: Stability testing and determination
(Elsevier B.V., 2024)
The anticholinergic drug, solifenacin, is frequently used for the treatment of the urological tract for urinary incontinence, and urinary frequency. The development of reliable and effective solifenacin electrochemical ...
Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Journal of Electroanalytical Chemistry, 2021)
Hydrated iridiumoxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier Science Sa, Lausanne, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
Mass transfer effect in electrochemical oxidation of methanol at platinum electrocatalysts
(Elsevier Science Sa, Lausanne, 2004)
The influence of the mass transfer on the electrochemical oxidation of methanol was investigated at a rotating disk electrode with smooth polycrystalline Pt and high area carbon supported Pt (Pt/C) as the electrocatalysts. ...
