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 ...
The influence of polypyrrole films on the corrosion behavior of iron in acid sulfate solutions
(Elsevier Science Sa, Lausanne, 1998)
The corrosion behavior of mild steel covered by electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from an aqueous solution of ...
Rheological behavior of cured acrylate-terminated unsaturated copolyesters
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
The viscoelastic properties of cured acrylate-terminated copolyesters were studied by means of dynamic mechanical analysis. The influence of terminal double bonds, as well as of the cis-trans configuration and distribution ...
Immobilization of lipase from Candida rugosa on a polymer support
(Springer, New York, 1998)
Lipase from Candida rugosa was immobilized by adsorption onto a macroporous copolymer support. Under optimum conditions the maximum amount of protein bound was 15.4 mg/g and the immobilization efficiency was 62%. The ...
Template effect in caesium selective phenolic resins
(Kluwer Academic Publ, Dordrecht, 1998)
Two new phenolic resins have been synthesised by alkaline polycondensation of resorcinol and acetaldehyde using template polymerisation. The extraction properties of the resins have been evaluated in competitive extraction ...
Kinetics of the reactions of pyridine and pyridine-N-oxide carboxylic acids and substituted benzoic acids with diazodiphenylmethane in various alcohols
(Sage Publications Ltd, London, 1998)
Solvent effects on the reactivity of pyridine and pyridine-N-oxide carboxylic acids and p-substituted benzoic acids in their reaction with diazodiphenylmethane (DDM) in alcohols have been investigated and the rate constants ...
Synthesis of cordierite powder performed under the conditions of periodic ultrasonic fields activity
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
In this article, the influence of periodic physical field, on the given system, is presented by the example of the ultrasonic spraying of various aerosol precursors used for ceramic powder synthesis. A general model, ...
2D model of pseudomorphic InGaAs/InAlAs HEMT's structure
(Trans Tech-Scitec Publications Ltd, Durnten-Zurich, 1998)
This paper presents the 2D model of the pseudomorphic InGaAs/InAlAs/InGaAs HEMT (High Electron Mobility Transistor) structure based on relevant physics. Together with parameters governed by the geometry and the producing ...
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 ...
O2 reduction on on ink-type rotating disk electrode using Pt supported on high-area carbons
(Electrochemical Soc Inc, Pennington, 1998)
The kinetics of O2 reduction has been examined on an ink-type electrode made with Pt supported on high-area carbon. Electrocatalysls with 5-40 mass % of Pt on Black Pearls, Vulcan XC-72, and Shawinigan acetylene black ...
