The extremely high stability of carbofuran pesticide in acidic media / Ekstremno visoka stabilnost pesticida karbofurana u kiseloj sredini
(Faculty of Technology, Novi Sad, 2007)
Environment friendly iron catalysts were applied in the decomposition reactions of some toxic compounds like phenol, methomyl and corbofuran pesticide. The applied catalytic processes belong to photo-Fenton reactions. ...
Effects of substituents on the electronic absorption spectra of 3-N-(4-substituted phenyl)-5-carboxy uracils in different solvents: Part II / Efekat supstituenata na apsorpcione spektre 3-N-(4-supstituisanih fenil)-5-karboksi uracila u različitim rastvaračima - deo II
(Serbian Chemical Society, Belgrade, 2000)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils, previously determined in twelve solvents, are correlated with substituent sp+ values or by dual substituent parameter correlations involving sI and ...
Prediction of service life of cordierite-mullite refractory materials by non-destructive methods
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
Ultrasonic pulse velocity testing was used to perform non-destructive quality control of refractory plates used as substrates in fast firing of porcelain whitewares. The measurement of the ultrasonic velocity was used to ...
Influence of Cu and Mn content on the properties of Al-Mg4.5-(Mn,Cu) type alloy sheets
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Influence of Cu and Mn content on the grain structure, precipitation effects and mechanical properties of two Al-Mg4.5-(Mn,Cu) type sheets was considered. It was found that a variety of grain size can be obtained in alloy ...
Polymers contamination by heavy metal compounds / Kontaminacija polimera teškim metalima
(Association of Chemical Engineers of Serbia, 2002)
The contamination of important synthetic (surface unmodified) polymers by various heavy metal compounds (such as copper, manganese and lead) in aqueous medium was investigated in this study. The influence of the pH of the ...
Structural effects during CO adsorption on Pt-bimetallic surfaces I. The Pt(100) electrode
(Elsevier, Amsterdam, 2000)
Synchrotron surface X-ray scattering (SXS) and rotating ring disk electrode (RRDE) measurements have been performed during the coadsorption of metal adatoms and carbon monoxide on the Pt(100) surface in an electrochemical ...
The influence of the deposition parameters on the porosity of thin alumina films on steel / Uticaj parametara elektroforetskog taloženja praha aluminijum-oksida iz vodenih suspenzija na poroznost dobijenih tankih filmova na čeliku
(Serbian Chemical Society, Belgrade, 2004)
The influence of the deposition parameters on the porosity of thin alumina films electrophoretically deposited on steel from aqueous suspensions was investigated. The effects of the applied voltage, deposition time, ...
Lipase immobilization in a hollow fibre membrane reactor: Kinetics characterization and application for palm oil hydrolysis
(Versita, Warsaw, 2004)
Feasibility of lipase immobilization in a hydrophilic hollow fibre membrane reactor for oil hydrolysis has been demonstrated. A simple immobilization technique was applied resulting in about 155 mg m(-2) of immobilized ...
Effects of plastic deformation on the properties of W-Ni-Fe heavy alloys
(International Institute for the Science of Sintering, Beograd, 2001)
The effects of reduction in area due to rotary forging on the structure, physical and mechanical properties of 92,5W-5Ni-2,5Fe heavy alloy rods have been presented in this paper. Sintered rods (20mm) were rotary forged ...
Correlation of osmotic coefficient data for ZnSO4(aq) at 25 degrees C by various thermodynamic models
(Kluwer Academic/Plenum Publ, New York, 2003)
The available literature data on the osmotic coefficient of ZnSO4(aq) at 25degreesC in the molality range from 0.1 to 4.3 mol-kg(-1) and new experimental data from 1.2 to 2.9 mol-kg(-1), at the same temperature, are ...
