Synthesis and characterization of semi-interpenetrating networks of chitosan and poly(N-vinyl-2-pyrrolidone) / Sinteza i karakterizacija semi-interpenetrirajućih mreža hitozana i poli(N-vinil-2-pirolidona)
(Association of Chemical Engineers of Serbia, 2010)
Semi-interpenetrating networks (semi-IPNs) based on chitosan and poly(N-vinyl-2-pyrrolidone) were prepared in order to achieve better mechanical properties. The samples were characterized by FTIR, SEM, DMA analysis and the ...
Modeling the kinetics of calcium hydroxide catalyzed methanolysis of sunflower oil
(Elsevier, 2010)
The kinetics of Ca(OH)2-catalyzed methanolysis of sunflower oil was studied at a moderate temperature (60 °C), a methanol-to-oil molar ratio (6:1) and different catalyst amounts (from 1% to 10% based on oil weight). The ...
Fluidized bed combustion of pesticide-manufacture liquid wastes / Sagorevanje tečnog otpada fabrike pesticida u fluidizovanom sloju
(Serbian Chemical Society, 2010)
Industrial liquid wastes can be in the form of solutions, suspensions, sludges, scums or waste oil and have organic properties. The objective of this work was to demonstrate the technical feasibility of a fluidized bed as ...

Application of a Structural Integrity Assessment Software
(3rd International Multi-Conference on Engineering and Technological Innovation, IMETI 2010, 2010)
In this paper, a brief overview is given of two projects concerning structural integrity assessment, including on-line software based on SINTAP procedure. An example of the software usage is presented, and the obtained ...
Hydrogels of N-isopropylacrylamide copolymers with controlled release of a model protein
(Elsevier Science Bv, Amsterdam, 2010)
Temperature- and pH-sensitive hydrogels, based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), were synthesized by free radical crosslinking copolymerization in the presence of lipase from Candida rugosa. The ...
Primena džibre tritikalea za proizvodnju mlečne kiseline / Triticale stillage appliance for lactic acid production
(Beograd : Tehnološko-metalurški fakultet Univerziteta, 2010)
Triticale is a very applicable crop for bioethanol production, and also provides a stillage that can be used as a feed. The main aim of this research was to investigate the possibility of transformation of unused stillage ...
Influence of notch radius and microstructure on the fracture behavior of Al-Zn-Mg-Cu alloys of different purity
(Elsevier, 2010)
The influence of notch radius on the fracture behavior of two high-strength Al-Zn-Mg-Cu alloys with different Fe content in the T73 condition was investigated. The fracture toughness tests were performed on non-fatigue-precracked ...
Synthesis, characterization and application of poly(N-isopropylacrylamide-co-itaconic acid) hydrogels as supports for lipase immobilization
(Elsevier Science Bv, Amsterdam, 2010)
Temperature- and pH-sensitive hydrogels based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA) were applied for immobilization of lipase from Candida rugosa (CRL). The hydrogels were synthesized by free radical ...
