Semi-interpenetrating networks based on POLY(N-isopropyl acrilamide) and POLY(N-vinylpyrrolidone) / Semi-interpenetrirajuće polimerne mreže na bazi POLI(N-izopropilakrilamida) i POLI(N-vinilpirolidona)
(Association of Chemical Engineers of Serbia, 2007)
Three series of semi-interpenetrating polymer networks based on cross-linked poly(N-isopropylacrylamide), PNIPA, and 1, 2 and 3 wt% of linear poly(N-vinylpyrrolidone), PVP, were synthesized in order to improve the mechanical ...
Preliminary studies on controlled release of acetylsalycilic acid from membrane module
(Association of Chemical Engineers of Serbia, 2004)
Controlled swelling and degradation studies of alginate microbeads in dilute natrium citrate solutions / Ispitivanje mogućnosti kontrolisanog bubrenja i razgradnje alginatnih mikročestica u razblaženim rastvorima natrijum-citrata
(Association of Chemical Engineers of Serbia, 2010)
Alginate hydrogels are widely used in biomedicine due to alginate availability, hydrophilic nature, biocompatibility and biodegradability. Alginate microbeads are particularly attractive for applications in pharmacy and ...

(Association of Chemical Engineers of Serbia, 2011)
This study evaluated the effect of accelerated aging on tensile strength, elongation at break, hardness and Charpy impact strength in commercial PMMA denture base material modified with di-methyl itaconate (DMI) and ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Thermal resistance testing of standard and protective filtering military garment on the burning napalm mixture / Testiranje termičke otpornosti standardne i filtrirajuće zaštitne vojničke uniforme na goruću napalm smešu
(Association of Chemical Engineers of Serbia, 2013)
Fires are an accompanying manifestation in modern weaponry use and in various accidents in peacetime. The standard military uniform is a primary barrier in protection of a soldier's body from all external influences, ...
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 ...
Improvement of antioxidant properties of egg white protein enzymatic hydrolysates by membrane ultrafiltration
(Savez hemijskih inženjera, Beograd, 2016)
The production of bioactive peptides from egg white proteins (EWPs) and their separation are emerging areas with many new applications. The objective of this study was to compare antioxidant activity of three distinct EWP ...
