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 ...
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 ...
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 potential of piezoelectric sensors for characterization of activated carbon cloth applied in adsorption of phenols from air
(Amer Chemical Soc, Washington, 1998)
Characterisation of activated carbon cloth (ACC) applied for phenols adsorption from the air was performed by a pair of coated piezoelectric quartz crystals as sensors. ACC cloth was impregnated with specific organic ...
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) ...
The use of chitosan on hydrogen peroxide pretreated wool
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 1998)
Since chlorination is known to produce substantial pollution with adsorbable organo halogens (AOX) in textile wastewater, shrink resist treatments like the widely used chlorine/Hercosett process are no longer environmentally ...
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 ...
