Microeconomics of the materials and energents consumption in a simulated copper casting process
(Edimet SpA, 2012)
An analytical model for the optimization of the consumption of materials and energents in a typical copper casting process based on a standard simulation procedure is presented. The proposed microeconomic analysis in ...
Geopolymerization of low-grade bauxite
(Institute of Metals and Technology, 2014)
In terms of quality, bauxite ore can be classified as high- or low-grade ore. High-grade bauxite ores are used for alumina extraction using the Bayer process, while low-grade bauxite ores have a limited application. In ...
The influence of service solutions on the longitudinal and circumferential tensile properties of glass-polyester composite pipes
(Springer, New York, 2011)
In numerous cases, metals and alloys traditionally used as structural materials in the process equipment can now be successfully replaced by nonmetallic composite materials. We study the influence of service solutions on ...
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., ...
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 ...

Solid state synthesis of extra phase-pure Li4Ti5O12 spinel
(Belgrade : International Institute for the Science of Sintering, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800°C. ...
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 ...
Influence of Alkali Cation on the Mechanical Properties and Durability of Fly Ash Based Geopolymers
(Slovenian Chemical Society, 2013)
This research has provided information about the influence of alkali cations (Na+ and K+) on the mechanical properties and durability of fly ash based geopolymers. The results have shown that alkali cations have a strong ...
