Continuous biodisel productions: A review / [Kontinualni postupci dobijanja biodizela]
(Association of the Chemical Engineers of Serbia, 2009)
Continuous biodiesel production on laboratory and industrial scale was analyzed, with focus on their advantages and disadvantages. Attention was paid to specific characteristics of industrial processes in order to point ...
Immobilization of lipase from Candida rugosa into copolymer hydrogels of poly(N-isopropylacrylamide-co-itaconic acid) synthesized in the presence of surfactants / Imobilizacija lipaze iz Candida rugosa u kopolimerne hidrogelove poli(N-izopropilakrilamid-ko-itakonska kiselina) sintetisane u prisustvu površinski aktivnih materija
(Association of Chemical Engineers of Serbia, 2011)
To overcome the problems of free enzyme application as catalysts in chemical reactions, i.e., high costs of isolation and purification processes, high sensitivity to process conditions, insufficient enzyme stability etc., ...
Liquid transfer properties of textile fabrics as a function of moisture content
(Savez hemijskih inženjera, Beograd, 2020)
Liquid transport in textile fabrics determines thermal comfort during high physical activity of a person when liquid perspiration is produced and needs to be transferred away from the skin to keep the thermal balance. In ...
Improvement of cavitation resistance of composite films using functionalized alumina particles
(Savez hemijskih inženjera, Beograd, 2018)
Composite films having the UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina (Al2O3 Fe) based particles were prepared and subjected ...
Synthesis and swelling behavior of polyurethane networks based on hyperbranched polymer
(Hemijska industrija, 2011)
A series of six polyurethane (PU) networks was synthesized from Boltorn (R) hydroxy-functional hyperbranched polyester (HBP) of the second pseudo generation as a cross-linking agent, alpha,omega-dihydroxy-(ethylene ...
Synthesis and characterization of copolymer hydrogels of chitosan, itaconic acid and N-isopropylacrylamide / Sinteza i karakterizacija kopolimernih hidrogelova hitozana, itakonske kiseline i N-izopropilakrilamida
(Association of Chemical Engineers of Serbia, 2011)
This paper deals with the synthesis of copolymer hydrogels of N-isopropylacrylamide, itaconic acid and chitosan. During synthesis, pH of the reaction solution and temperature were varied. It was found that the reaction at ...
Optimization of gradual hemolysis for isolation of hemoglobin from bovine erythrocytes / Optimizacija procesa izolovanja hemoglobina iz goveđih eritrocita kontrolisanom hemolizom
(Association of Chemical Engineers of Serbia, 2012)
In this work, we describe an optimized procedure based on gradual hemolysis for the isolation of hemoglobin derived from bovine slaughterhouse erythrocytes in a membrane bioreactor. The membrane bioreactor system provided ...
Impact of leaching procedure on heavy metals removal from coal fly ash / Uticaj metode izluživanja na uklanjanje teških metala iz letećeg pepela
(Savez hemijskih inženjera Srbije, 2024)
In this work, removal of heavy metals (Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) from fly ash has been studied using acid leaching and wet oxidation methods. In parallel, microwave-assisted acid digestion was applied for ...
