(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
The aim of this work was to obtain the stable - powdered polycomponent preparation based on fermented soybean extract that is supplemented with beetroot juice and yeast autolysate with preserved biological activity. Such ...
Dependence of the solid-liquid interface structure on the solidification process parameters / Zavisnost strukture granice faza tečno-čvrsto od parametara procesa očvršćavanja
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Influence of the solidification rate, temperature gradient and initial concentration of the solute on the interface shape was investigated during solidification from the melt. The dependence of the microstructure on the ...
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 ...
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 ...
