Swelling kinetics and impregnation of PLA with thymol under supercritical CO2 conditions / Kinetika bubrenja PLA i njegova impregnacija timolom upotrebom natkritičnog uglenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The present work was aimed to study swelling kinetics of polylactic acid (PLA) and its impregnation with thymol in supercritical carbon dioxide (scCO2) medium. The influences of temperature and soaking time on the swelling ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...

(Association of Chemical Engineers of Serbia, 2012)
The aim of this paper is to propose equations for the diffusion of drugs for investigated drug/hydrogel systems using the parameters affecting the transport of drug through poly- (2-hydroxyethylmethacrylate/itaconic acid) ...
Dynamic mechanical properties of aramid fabrics impregnated with multiwalled carbon nanotubes / Dinamičko mehanička svojstva aramidnih lamina impregnisanih sa višeslojnim ugljeničnim nanocevima
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Carbon nanotubes (CNT) represent allotropes of carbon with a cylindrical nanostructure. In multiwalled carbon nanotubes (MWCNT), graphitic layers make up concentric tubes. The multiwalled nanotubes length in our research ...
Development of RuO2/TiO2 titanium anodes and a device for in situ active chlorine generation / Razvoj titanskih RuO2/TiO2 anoda i uređaja za in situ proizvodnju aktivnog hlora
(Association of Chemical Engineers of Serbia, 2013)
Chlorine is used worldwide for water disinfection purposes. However, due to its toxicity the EU has imposed a set of standards that must be applied when transporting and storing chlorine. In Serbia, numerous studies have ...
Dynamic mechanical properties of aramid fabrics impregnated with carbon nanotube/poly (vinyl butyral)/ethanol solution
(Association of Metallurgical Engineers of Serbia, 2013)
In this study six samples of polyurethane/p-aramid multiaxial fabric forms (Colon fabrics) were coated with 10 wt.% poly (vinyl butyral) (PVB)/ethanol solution with the addition of multiwalled carbon nanotubes (MWCNT). The ...
Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
