The effects of plasticizers on the properties of poly(vinyl chloride) foams
(Journal of Vinyl and Additive Technology, 2002)
The effects of plasticizers on poly(vinyl chloride) (PVC) plastisol mixtures were investigated. The investigations were carried out by determining the density of the PVC foam obtained by gelling the plastisol, as well as ...
Reversal of substituent effect on electronic absorption spectra of N-(4-substituted phenyl)-benzamides in different solvents
(Natl Inst Science Communication, New Delhi, 2002)
Absorption spectra of eleven N-(4-substituted phenyl)-benzamides have been recorded in ten solvents in the range 200400 nm. The substituents at the phenyl nucleus are as follows: N (CH3)(2), OCH3, CH3, H, Cl, Br, F, CN, ...
Selection of natural materials for In situ remediation and prevention of environment contamination by lead
(Grafima Loannis Tsarouchidis, Thessaloniki, 2002)
Stability of the solid matrix - contaminant system represents a crucial parameter in selection of the appropriate natural material for in situ remediation of the environment contaminated by toxic heavy metals. We have ...

Mass spectrometric study of some 4-pyrimidine carboxylic acids
(Wiley, Hoboken, 2002)
Mass spectrometry has been applied in order to study the main fragmentation routes of some 4-pyrimidene carboxylic acids. Differences in fragmentation were caused by the nature of the substituent in position 2 of the ...
Fibrous systems with programmed biological-activity and their application in medical practice
(Autex Research Journal, 2002)
An effective two-stage method for obtaining both biologically activated fibres with antibacterial and anaesthetic activity and biologically activated complex fibres -insulin as an artificial store of insulin has been ...
Comparison of two polymeric transition metal complexes with 1,4-benzenedicarboxylate ions as bridging ligands, [Co(C8H4O4)(C12H8N2)(H2O)] and [Cu(C8H4O4)(C10H9N3)] center dot H2O
(Int Union Crystallography, Chester, 2002)
The title complexes, catena-poly[[aqua(1,10-phenanthroline- kappa(2)N,N')cobalt(II)]-mu-benzene-1,4-dicarboxylato-kappa(2)O(1):O-4], [Co(C8H4O4)(C12H8N2)(H2O)], (I), and catena-poly[[[(di-2-pyridyl-kappaN-amine)copper(II ...
Corrosion behaviour of epoxy coatings on modified aluminium surfaces
(Bulletin of Electrochemistry, 2002)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces (anodized phosphatized and chromatized-phosphatized aluminium) have been ...
Methanol electrooxidation on supported Pt and PtRu catalysts in acid and alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% Pt-Ru (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
Alginate-immobilized lipase by electrostatic extrusion for the purpose of palm oil hydrolysis in lecithin/isooctane system
(Elsevier Sci Ltd, Oxford, 2002)
Lipase from Candida rugosa was immobilized in alginate beads for possible application in non-aqueous or microaqueous reaction systems. An electrostatic droplet generation technique was used for production of small diameter ...
