Formability of a high-strength Al Mg6.8 type alloy sheet
(Springer, New York, 1998)
Room temperature formability testing was performed on an AlMg6.8 type alloy sheet with a fully recrystallized structure (average grain diameter similar to 18 mu m) and after partial annealing with a retained deformed ...
Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
The determination of kinetics parameters of the hydrogen evolution on Ti-Ni alloys by ac impedance
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are ...
A novel triclinically deformed chabazite-like aluminophosphate prepared in the presence of tris(1,2-diaminoethane)nickel(II) chloride
(Elsevier, 1998)
The tris(1,2-diaminoethane)nickel(II) complex was found to be a novel structure-directing agent for the preparation of the chabazite-like AlPO4-34 molecular sieve. During crystallization the complex undergoes a ligand ...
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 ...
Electrochemically deposited thin films of amorphous Fe-P alloy Part I. Chemical composition and phase structure characterization
(Elsevier Science Sa, Lausanne, 1998)
Thin Fe-P alloy films (0.5 to 25.0 mu m thick) were electrodeposited from sulfate solutions. The influences of various deposition conditions (current density, time, pH and temperature) on the composition and structure of ...
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, ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, Amsterdam, 1999)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C6H4-X, X having a wide range of substituent effects, have been determined in CDCl3 solution. Exceptionally good ...
