The non-oxidative thermal degradation of poly (Di-2-chloroethyl itaconate)
(John Wiley & Sons Ltd, W Sussex, 1993)
The non-oxidative thermal degradation of poly (di-2-chloroethyl itaconate) (PD2CEI) was studied by TG and by analysing the thermal products. The major processes occurring during thermal analysis are crosslinking, ...
Electron‐impact induced decomposition of some 3‐alkyl‐5‐substituted‐6‐methyl uracils
(Wiley, Hoboken, 1995)
Mass spectrometry was used to study the main fragmentation routes of some 3‐alkyl‐5‐substituted‐6‐methyl uracils. Differences in fragmentation were caused by changes in the structure of the alkyl group in position 3 of the ...
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, ...
Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
In this paper, a model of substructure design of mullite powder particles obtained by spray pyrolysis lit the field of ultrasound excitation is described. Based an this model, the size of subparticles (nanoparticles) ...
Hydrodynamics and Mass Transfer in a Four‐Phase External Loop Air Lift Bioreactor
(Wiley, Hoboken, 1995)
An external loop air lift reactor (ELALR) was developed and designed for continuous production and extraction of extracellular secondary metabolites by immobilized Frangula alnus Mill. plant cells. This system was considered ...
Polymerization studies: The application of differential thermogravimetric analysis
(Wiley, Hoboken, 1993)
The application of differential thermogravimetric analysis (DTGA) to the study of polymerization mechanisms is illustrated using as examples the radical polymerization of di‐n‐alkyl itaconates and methyl methacrylate (MMA). ...
The flow of the viscous fluid around the sphere in the range Re {similar or less-than} 2
(Springer Wien, Wien, 1992)
An improved and more correct solution of Oseen's equations, when the flow of the incompressible viscous fluid around the sphere is concerned, has been suggested. The new Oseen's correction term of the Stokes solution for ...
