Studies on electrochemical oxidation of azithromycin and Hemomycin (R) at gold electrode in neutral electrolyte
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the ...
Polypyrrole as possible electrode materials for the aqueous-based rechargeable zinc batteries
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Polypyrrole (PPy) thin film electrode was galvanostatically synthesized and characterized in 0.1 M HCl on graphite electrode as cathode materials for the aqueous-based rechargeable zinc batteries. The charge/discharge ...
Methanol electrooxidation on supported Pt and Pt-Ru catalysts in acid and alkaline solutions
(Elsevier, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% PtRu (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
Characterization of electrodeposited powders of the system Ni-Mo-O
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The electrodeposition of the Ni-Mo-O alloy powders from ammonium chloride containing electrolytes for different Ni/Mo ions concentration ratios was investigated by the polarization measurements. The morphology, chemical ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt"Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
Study of the kinetics and influence of Bi_irr on formic acid oxidation at Pt2Ru3/C
(Elsevier, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HClO4 solutions was examined on thin film Pt2Ru3/C electrode. XRD pattern revealed that Pt2Ru3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
Formation of dish-like holes and a channel structure in electrodeposition of copper under hydrogen co-deposition
(Elsevier, 2007)
Copper electrodeposition from acid sulfate solutions at an overpotential of 1000 mV, which is about 250 mV outside the plateau of the limiting diffusion current density, was examined by the determination of the average ...
Oxidation of formaldehyde and ethanol on Au(1 1 1) and Au(1 1 1) modified by spontaneously deposited Ru in sulfuric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The oxidation of formaldehyde and ethanol on both pure Au(1 1 1) and Au(1 1 1) modified by approximately 0.3 monolayer (ML) of spontaneously deposited Ru was studied by cyclic voltammetry (CV) in 0.5 M H2SO4 solution ...
The electrochemical behavior of erythromycin A on a gold electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
Electrodeposition and morphology of Ni, Co and Ni–Co alloy powders Part II. Ammonium chloride supporting electrolyte
(Elsevier, 2007)
Polarization characteristics of the processes of Ni and Co powders and Ni-Co alloy powders electrodeposition from ammonium chloride containing supporting electrolyte and their morphologies are investigated as a function ...
