Influence of the damage level during quenching on thermal shock behavior of low cement castable
(International Institute for the Science of Sintering, Beograd, 2010)
In the recent decades, the use of unshaped monolithic refractories has been increasing greatly because of their significant advantages over other shaped refractory bricks of the same class. A low cement high alumina castable ...
Oxidative stabilization of sunflower oil by antioxidant fractions from selected Lamiaceae herbs / Oksidativna stabilizacija suncokretovog ulja sa antioksidativnim frakcijama iz odabranih biljaka familije Lamiaceae
(Association of the Chemical Engineers of Serbia, 2010)
This study reports the effect of antioxidant fractions from rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) on the oxidative stability of sunflower oil ...
Biodiesel synthesis using K2CO3/Al-O-Si aerogel catalysts / Sinteza biodizela katalizovana alumosilikatnim aerogelom sa K2Co3
(Serbian Chemical Society, Belgrade, 2010)
In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol-gel method, which was followed by drying ...
Drying of immobilized yeast cells in a spouted bed dryer with a moving draft tube / Sušenje imobilisanih ćelija pivskog kvasca u sušioniku sa fontanskim slojem i pokretnom centralnom cevi
(Association of the Chemical Engineers of Serbia, 2010)
Brewery yeast cells immobilized in Ca-alginate were dried in a laboratory scale spouted bed with a draft tube. The experiment was conducted under variable temperatures and air flow rates. The temperature and air velocity ...

Impact of roughness of Zn-Mn coatings on corrosive stability / Uticaj hrapavosti Zn-Mn prevlaka na korozionu postojanost
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This paper involves electrochemical deposition of Zn-Mn coatings from four solutions. We measured their roughness and corrosion stability. We used cathodes made of steel of unknown composition that were licensed under the ...
Simplification of the synthesis of the reversible addition-fragmentation chain transfer agent 2-(2-cyanopropyl)-dithiobenzoate / Pojednostavljenje postupka sinteze raft agensa 2-(2-cijanopropil)-ditiobenzoata
(Serbian Chemical Society, Belgrade, 2010)
The general literature procedure for the preparation of the reversible addition-fragmentation chain transfer (RAFT) agent 2-(2-cyanopropyl)-dithiobenzoate (CPDB) was modified by omitting the recrystallisation of the ...
