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 thermogravimetric analysis of some polysiloxanes
(Elsevier Ltd., 1998)
Thermogravimetric (TG) and differential thermogravimetric analyses (DTG) of some homo- and copolymers of dimethylsiloxane have been performed. The effect of the presence of hydrido-substituents and/or vinyl end-groups on ...
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 ...
The flow of the viscous fluid around the sphere in the range Re {similar or less-than} 2
(Springer Wien, Wien, 1992)
An improved and more correct solution of Oseen's equations, when the flow of the incompressible viscous fluid around the sphere is concerned, has been suggested. The new Oseen's correction term of the Stokes solution for ...
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 ...
Palm oil hydrolysis by lipase from Candida cylindracea immobilized on zeolite type Y
(Elsevier Science Inc, New York, 1998)
Lipase from Candida cylindracea immobilized on hydrophobic zeolite type Y was used to hydrolyze palm oil in a microaqueous two-phase reaction system containing isooctane as organic medium and lecithin as surfactant. The ...
Characterization of natural isolate Lactobacillus acidophilus BGRA43 useful for acidophilus milk production
(Wiley, Hoboken, 1998)
Lactobacillus acidophilus BGRA43 was selected from a set of human origin isolates of Lact. acidophilus strains for the highest growth rates and antagonistic effect against both Gram-positive and Gram-negative bacteria. The ...
Osmotic and activity coefficients of {yK(2)SO(4)+(1-y)Mg(NO3)(2)}(aq) at the temperature T = 298.15 K
(Academic Press Ltd, London, 1998)
'The osmotic coefficients of the mixed electrolyte solution {yK(2)SO(4) + (1 - y)Mg(NO3)(2)}(aq) have been measured by the isopiestic method, at the temperature T = 298.15 K. The activity coefficients of K2SO4 and Mg(NO3)(2) ...
Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metal intermetallic phases
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metals in their intermetallic phases and alloys for the hydrogen storage, hydridic batteries and its electrode reactions (HELR) ...
Underpotential deposition of lead onto Pt(100) in acid solutions: Adsorption isotherms and interface structures
(Royal Soc Chemistry, Cambridge, 1998)
The underpotential deposition (UPD) of Pb onto Pt(100) in pure perchloric acid and in solution containing Br- was examined by classical rotating ring disk electrode (RRDPt(100)E) electrochemical methods in combination with ...
