Synthesis, structure and solvatochromism of 5-methyl-5-(3-or 4-substituted phenyl)hydantoins / Sinteza, struktura i solvatohromizam 5-metil-5-(3- ili 4-supstituisanih fenil)-hidantoina
(Serbian Chemical Society, Belgrade, 2009)
Several 5-methyl-5-(3- or 4-substituted phenyl)hydantoins were prepared and their ultraviolet absorption spectra were recorded in the region 200-400 nm in twelve solvents of different polarity. The effect of solvent ...
Saturated-liquid heat capacity calculation of alkanes / Predskazivanje toplotnog kapaciteta zasićene tečnosti alkana
(Serbian Chemical Society, Belgrade, 2005)
An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria-Benson and Růžička-Domalski) using 68 sets with 1155 literature experimental ...

Viscoelastic properties of Na-alginate solution
(Association of Chemical Engineers of Serbia, 2004)
The evolution of oscillatory-induced structure of Na-alginate solutions was studied for various frequencies and concentrations. The specific rate of elastic modulus increase, as well as the specific rate of loss modulus ...
The influence of electrochemically deposited zinc alloys on steel on the protective properties of cathaporetic epoxy coatings / Uticaj elektrohemijski taloženih legura cinka na čeliku na zaštitna svojstva epoksidne kataforetske prevlake
(Engineering Society for Corrosion, Belgrade, Serbia, 2005)
Prior to cathaporetic epoxy coating deposition steel surface was modified by chemical deposition of hot dip galvanized steel and by electrochemical deposition of zinc alloys with iron group of elements (Ni, Co and Fe). The ...
Electrochemical deposition and characterization of Zn-Fe alloys / Elektrohemijsko taloženje i karakterizacija Zn-Fe legura
(Serbian Chemical Society, Belgrade, 2004)
Zn–Fe alloy electrochemically deposited on steel under various deposition conditions were investigated using anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) analysis for phase structure determination, ...
Korozija metala - šta je to?
(Engineering Society for Corrosion, Belgrade, Serbia, 2004)
Korozija materijala je opšte poznat i prihvaćen izraz, ali da li se baš tačno zna šta je korozija? Pod pojmom korozija materijala se podrazumeva svako neželjeno razaranje materijala kao posledice delovanja spoljne sredine. ...
