Reaction of a new thiol cationic surfactant with bunte salt in wool fibers
(Textile Research Inst, Princeton, 1997)
A new, effective, specific quaternary ammonium compound, N-dodecyl-amino-betaine-2-mercaptoethylamine hydrochloride (DABM), is synthesized to confer permanent characteristics (antimicrobial properties, improved dyeing and ...
Underpotential deposition of lead on Pt(111) in perchloric acid solution: RRDPt(111)E measurements
(Amer Chemical Soc, Washington, 1997)
Underpotential deposition (UPD) of lead (Pb-upd) on Pt(111) in perchloric acid solution was studied using the rotation ring disk, electrode (RRDPt(111)E) method for measurements of the Pb2+ ion-specific flux. The total ...
Rhizopus arrhizus lipase-catalyzed interesterification of palm oil midfraction in a gas-lift reactor
(Elsevier Science Inc, New York, 1994)
Celite-immobilized lipase from Rhizopus arrhizus was encapsulated in lecithin reverse micelles and used to interesterify triacylglycerols of palm oil midfraction with stearic acid in n-hexane. The reaction kinetics were ...
One more general method for solving Oseen's equations
(Springer Wien, Wien, 1991)
In this paper we have proposed a new method for solving the Oseen's equations. It has been testified in the case of the normal flow around the cylinder for the Re number being much smaller than 1. The step forward was to ...
Determination of new ASOG-H parameters of CyCH, furfural and DMSO groups
(Serbian Chemical Society, Belgrade, 1996)
New interaction parameters for the groups CYCH(1)-furfural(2) and CyCH(1)-DMSO(2) of the ASOG-H model were determined, for 293.15 K-323.15 K and 303.15 K-323.15K respectively. The values of the CyCH(1)-furfural(2) parameters ...
Effect of test variables on apparent activation energy for hot working and critical recrystallization temperatures of V-microalloyed steel
(Verlag Stahleisen Mbh, Dusseldorf, 1997)
The effect of test variables on the apparent activation energy for hot working of a medium carbon V-microalloyed steel, Q(HW), and the critical recrystallization temperature, T-nr, have been studied by means of isothermal ...
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 ...
Leaching kinetics of lead from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions
(Elsevier Science Bv, Amsterdam, 1997)
The kinetics of lead leaching from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions was studied. The leaching rates of lead were measured by using an agitated vessel at atmospheric pressure, ...
Thermal shock of ceramic material : Comparison of resistance parameter with the critical ΔT values ΔTc = ΔTc(Bi) of ceramic materials
(Trans Tech Publications Ltd., 1997)
Thermal shock resistance of ceramic material can be characterized by using resistance parameters or critical temperature difference. Correlation between fracture resistance parameter, R and critical temperature difference, ...
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, ...
