The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions
(Serbian Chemical Society, Belgrade, 1997)
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions was studied. The lead leaching rates were measured using an agitated vessel at atmospheric pressure. The effects of the MgCl2 ...
The thermal degradation kinetics of isomeric poly(dipropyl, itaconates)
(Springer, Dordrecht, 1997)
Non-isothermal thermogravimetry was performed in a dynamic nitrogen atmosphere, on a series of poly(di-n-propyl itaconates) (PDnPI) and poly(di-iso-propyl itaconates) (PDiPI) which had been prepared in the presence of ...
Effect of substituents on the C-13 NMR chemical shifts of para-substituted alpha-phenyl-beta-pyridylacrylic acids
(Elsevier, Amsterdam, 1997)
The C-13 NMR spectra of para-substituted alpha-phenylcinnamic and 3- and 4-pyridylacrylic acids, with a wide range of substituents effects, were determined in deuterated dimethylsulfoxide (DMSO-d(6)). The effect of ...
Comparison of critical ΔT-values with R-parameters of thermally shocked alumina refractories
(Expert Fachmedien GmbH, 1997)
The thermal shock stability of ceramic materials can be characterized using critical temperature difference or resistance parameters. Resistance parameters R and Rst are used in this paper. Two ways of representing thermal ...
Recent advances in homogeneous and heterogeneous asymmetric catalysis with nitrogen-containing ligands
(Baltzer Sci Publ Bv, Bussum, 1997)
Nitrogen-containing chiral ligands are being used more and more in asymmetric catalysis. This article is an overview of results published in 1993-1996 in this field and tries to open new perspectives for this type of ligand, ...
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 ...
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 ...
Boron and phosphorus doped glassy carbon: I. Surface properties
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
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 ...
The retention behavior of some anilides on unconventional TLC supports
(Akademiai Kiado Zrt, Budapest, 1997)
The TLC retention behavior of formanilide and I substituted acetanilides on starch and cellulose layers has been studied using aqueous mobile phases with methanol, acetonitrile, acetone, and 1-propanol as modifiers, R-Mw ...
