Corrosion protection of mild steel by polypyrrole coatings in acid sulfate solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The corrosion behaviour of mild steel covered by the electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from aqueous solution of ...
Hydrogen evolution at Zn-Ni alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Zn-Ni alloys were electrodeposited from a berate-citrate and TEPA bath in potentiostatic and galvanostatic regimes. Potential of electrodeposition or current density were varied and chemical composition and phase structure ...
Study of the kinetics and the influence of Bi-irr, on formic acid oxidation at Pt2RU3/C
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HCIO4 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 ...
Comparative studies of chloride and chloride/citrate based electrolytes for zinc-polyaniline batteries
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Electrochemical behavior of zinc and thin polyaniline (PANI) polymerized from 0.1 M HCl to 0.1 M aniline on graphite electrode, in 0.2 M ZnCl(2) and 0.50 M NH(4)Cl (chloride electrolyte) and with addition of 0.33 M Na-citrate ...
Electrooxidation of H-2, CO and H-2/CO mixtures on a well-characterized Pt-Re bulk alloy electrode and comparison with other Pt binary alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
We report new results for the electrooxidation of Hz, CO and H-2/CO mixtures on a Pt75Re25 bulk alloy using surface preparation in a UHV chamber and characterization by X-ray photoelectron spectroscopy (XPS). Sputter-cleaned ...
Methanol electrooxidation on supported Pt and PtRu catalysts in acid and alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% Pt-Ru (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 ...
UPD of Cu on Pt(100): effects of anions on adsorption isotherms and interface structures
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The results presented in this study show definitely that copper deposition in perchloric acid is a very slow, kinetically controlled process. In nearly halide free supporting electrolytes du appeared to be deposited at ...
Corrosion behaviour of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloy
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel: phosphatised steel and steel previously modified by electrodeposited Zn-Ni alloy was investigated during exposure to 3% NaCl. The ...
Electrochemical deposition and characterization of Zn-Co alloys and corrosion protection by electrodeposited epoxy coating on Zn-Co alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Voltammetric and differential pulse determination of roxithromycin
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The oxidative behavior of antibiotic roxithromycin standard was studied at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry and differential pulse voltammetry. It was found that the value of the ...
