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 ...
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 ...
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, ...
Liposomes as carriers of antimicrobial drugs
(Taylor & Francis Ltd, Abingdon, 1997)
Liposome are promising drug carrier systems being developed. Their successful use in the treatment of several diseases demonstrates that a solid rationale for clinical development of liposomes as antimicrobial drug carriers ...
The applicability of DTG to polymerisation studies
(John Wiley & Sons Ltd, W Sussex, 1993)
The application of derivativ thermogravimetry (DTG) to investigate polymerisation mechanisms is illustrated using the radical polymerisation of di-n-alkyl itaconates as well as the photoinitiated polymerisation of methyl ...
