The non-oxidative thermal degradation of poly(di-n-alkyl itaconates). II. Analysis of the polymer residue
(Elsevier Sci Ltd, Oxford, 2005)
The residues remaining after the thermal degradation of poly(di-n-alkyl itaconates) with ester substituents ranging from methyl to n-octyl were studied. It was found that the thermal stability of the polymers decreased ...
Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
Surface characterization of macroporous glycidyl methacrylate based copolymers by inverse gas chromatography
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, with different porosity parameters were synthesized by suspension copolymerization and modified by ring-opening ...
Application of ANOVA method to precipitation behaviour studies
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 2005)
The Analysis of variance (ANOVA) method has been used to illustrate the implementation of adaptive numerical (AN) techniques for the prediction of the precipitation behaviour of commercial materials. Case studies involving ...
Synthesis and single-crystal structure analysis of a new layered zinc phosphate
(Pure and Applied Chemistry, 2005)
A new 2D zinc phosphate [H3NCH(CH3)CH 2NH3]2+0.75[COOH(CH 2)COOH]0.25 (Zn3P3O 11OH)2-* 0.5NH4+ consists of zinc phosphate layers, which are intercalated by diprotonated 1,2-diaminopropane, malonic acid, and NH4+ ions. The ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
