Detecting aniline in air in systems based on piezoelectric quartz crystal resonators modified with poly(ethylene glycol succinate) under static and dynamic conditions
(Journal of Analytical Chemistry, 2000)
The optimal conditions have been found for aniline sorption on a film of poly(ethylene glycol succinate) by the piezoelectric quartz crystal microbalance method using bulk acoustic wave sensors based on AT-cut quartz ...
Physical-mechanical phenomenon of woven and non-conventional materials
(Emerald Group Publishing Limited, Bradford, 2000)
The basic idea of this project is in developing series of methods for monitoring structural parameters, as well as establishing their relation with the behaviour of woven and non-woven materials. Establishing the connection ...
Approach to laminar phenomena occurring on external and internal surfaces of solid specimens
(Kluwer Academic Publishers, 2000)
This article presents a general mathematical model for describing the laminar transport phenomena during homogeneous/heterogeneous appearances in the neighborhood of external and internal surfaces of small solid specimens. ...
Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
Mass spectrometry analysis of polychlorinated biphenyls: Chemical ionization and selected ion chemical ionization using methane as a reagent gas
(Serbian Chemical Society, 2000)
In the present paper a quadrupole ion trap mass spectrometer, coupled with a gas chromatograph, was used to compare the electron impact ionization (El) and chemical ionization (Cl) technique, in terms of their selectivity ...
Kinetics and mechanism of the reaction of substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane in dimethylformamide
(Scientific Reviews Ltd., 2000)
Correlation of the data for the reaction of 11 substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) with calculated atomic charges on the carboxylic group showed that the ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Polycyclic aromatic compounds in wood preservatives derived from coal and petroleum / Policiklični aromatski ugljovodonici u sredstvima za zaštitu drveta na bazi uglja i nafte
(Association of Chemical Engineers of Serbia, 2000)
Five commercial coal tar oils (DB, B, GX, PO, MA) and an oil sample derived from petroleum (RPO) were investigated in this work. The contents of benzo[a]pyrene (B[a]P) and 13 other polycyclic aromatic compounds (PACs) were ...
