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 ...
Rhamnolipid and lipase production by Pseudomonas aeruginosa san-ai: The process comparison analysis by statistical approach / Proizvodnja ramnolipida i lipaze iz Pseudomonas aeruginosa san-ai - optimizacija procesa primenom metode odzivnih površina
(Association of Chemical Engineers of Serbia, 2013)
Pseudomonas aeruginosa has been repeatedly reported as a powerful producer of rhamnolipid biosurfactants as well as hydrolytic enzymes. In this study, the effects of four fermentation factors were evaluated using response ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
