A novel triclinically deformed chabazite-like aluminophosphate prepared in the presence of tris(1,2-diaminoethane)nickel(II) chloride
(Elsevier, 1998)
The tris(1,2-diaminoethane)nickel(II) complex was found to be a novel structure-directing agent for the preparation of the chabazite-like AlPO4-34 molecular sieve. During crystallization the complex undergoes a ligand ...
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 ...
Condensation of 1,3-diketones with cyanoacetamide: 4,6-disubstituted-3-cyano-2-pyridones

Kinetics of lipase-catalyzed hydrolysis of palm oil in lecithin/izooctane reversed micellles
(Springer, New York, 1998)
Candida rugosa lipase has been used to investigate the hydrolysis of palm oil in a lecithin/isooctane reversed micellar system. The reaction obeys Michaelis-Menten kinetics for the initial conditions. Kinetic parameters ...
Stress state effect on dynamic strain aging and surface markings during stretching of AlMg7 alloy sheet
(Trans Tech Publications Ltd., 1998)
Stress state effect on dynamic strain aging (DSA) and the related surface appearance was analyzed in uniaxial and biaxial room temperature stretching of AlMg7 alloy sheet. In uniaxial tension the serrated yielding was found ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed This model includes momentum, heat and mass balance equations The density, viscosity and specific heat of the glass were calculated as functions of ...
Cubic equation of state models for liquid excess heat capacity calculations. II. Applicability of the PRSV-SR and PRSV-HVOS models to complex binary mixtures
(Serbian Chemical Society, Belgrade, 1998)
Binary liquid excess heat capacities C-p(E) for various kinds of complex binary systems measured by Conti and coworkers are well represented by the PRSV EOS modified van der Waals one fluid mixing rule proposed by ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
Modeling of drawing thin glass sheet from a preform
(Serbian Chemical Society, Belgrade, 1998)
A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane
(Serbian Chemical Society, Belgrade, 1998)
The rate constants for 10 trans-substituted beta-aroylacrylic acids in their reaction with diazodiphenylmethane (DDM) were determined in ethanol at 30 degrees C. The intention was to study the transmission of electronic ...
