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 ...
Removal of organochlorine pesticides from water using virgin and regenerated granular activated carbon / Uklanjanje pesticida iz vode na granulisanom aktivnom uglju
(Serbian Chemical Society, Belgrade, 2010)
Public water systems use granular activated carbon in order to eliminate pesticides. After saturation, the used activated carbon is regenerated and reused in order to reduce the costs of water production and minimize waste. ...
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 ...

New Hybrid Properties of TiO2 Nanoparticles Surface Modified With Catecholate Type Ligands
(Springer, New York, 2010)
Surface modification of nanocrystalline TiO2 particles (45 ) with bidentate benzene derivatives (catechol, pyrogallol, and gallic acid) was found to alter optical properties of nanoparticles. The formation of the inner-sphere ...
Hydroxyapatite coatings on TiO2 nanotubes / Prevlake hidroksiapatita na nanotubama oksida titana
(Engineering Society for Corrosion, Belgrade, Serbia, 2010)
The aim of this work was to obtain nanotubular TiO2 layer by anodization of titanium substrate, and to prepare hydroxyapatite (HAP) coatings by electrophoretic deposition over nanotubular TiO2 layer. The presence of fluoride ...
