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 ...
The acid resistance and corrosion stability of polyester coatings on phosphatized steel
(Serbian Chemical Society, Belgrade, 1998)
Protective polyester coatings on phosphatized steel were obtained with different combinations of diols (2-butyl-2-ethyl-1,3-propanediol or 2,2-dimethyl-1,3-propanediol), organic acids (1,3-cyclohexanedicarboxylic acid, ...
Selection of Calculation Method for Temperature Distribution in 99 Mass-% Al 2 O 3 Refractories
(Verlag Schmidt GmbH, 1998)
Refractories are constantly exposed to temperature changes. In most cases this exposure causes damage. In this work, attention is paid to problems of non-steady-state heat transfer. Some analytical and numerical methods ...
Nonlinear frequency response of adsorption systems: isothermal batch and continuous flow adsorbers
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The problem of nonlinear frequency response of adsorption systems is treated using the concept of higher-order frequency response functions (FRFs). The FRFs on the adsorber and on the particle scale are considered. Based ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - I. A semi-batch adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A semi-batch mode of operation is considered, ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - II. A continuous flow adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A continuous mode of operation is considered, ...
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 ...
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 ...
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) ...
