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 ...
Preparation of aluminophosphate molecular sieves in the presence of nickel( II) and copper( II)
(Butterworth-Heinemann, 1991)
Nickel(ll)-substituted aluminophosphates of structure types 21 and 12 (NiAPO-21 and NiAPO-12) have been prepared hydrothermally in the presence of ethylenediamine as the template. U.v.-visible spectroscopy of NiAPO-21 ...
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 ...
Thermal investigations of some AlPO and MeAPO materials prepared in the presence of HF
(Elsevier, Amsterdam, 1997)
Hydrothermal synthesis of chabazite-like AlPO4 in a fluoride medium, using piperidine as the structure directing agent, is also successful in the preparation of transition-metal-modified AlPO products. The transition metal ...
CdS nanoclusters: Synthesis, characterization, size dependent oscillator strength, temperature shift of the excitonic transition energy, and reversible absorbance shift
(Journal of Physical Chemistry, 1994)
Improved synthetic routes and size-selective precipitation have enabled the preparation of almost monodisperse CdS clusters. Six samples of 1-thioglycerol stabilized clusters with diameters of approximately 13, 14, 16, 19, ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Elsevier Science Sa, Lausanne, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
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 ...
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 ...
