Spectroscopic and quantum chemical elucidation of newly synthesized 1-aryl-3-methyl-3-phenylpyrrolidine-2,5-diones as potential anticonvulsant agents
(Savez hemijskih inženjera, Beograd, 2019)
Novel succinimide derivatives were synthesized from 3-methyl-3-phenylsuccinic acid and substituted anilines under solvent-free conditions by using microwave irradiation. All obtained compounds were characterized by ultraviolet ...
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 ...
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 ...
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 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 ...
Crosslinked polyurethanes based on hyperbranched polymers / Umreženi poliuretani na bazi hiperrazgranatih polimera
(Association of Chemical Engineers of Serbia, 2008)
In this paper, two samples of polyurethane (PU) crosslinked with hydroxy -functonal hyperbranched aliphatic polyester of the second pseudo generation were investigated. For the synthesis of these crosslinked PUs two different ...
Priprema i karakterizacija lipozoma sa inkapsuliranim bioaktivnim hidrolizatom proteina soje / Production and characterization of liposomes with encapsulated bioactive soy protein hydrolysate
(Savez hemijskih inženjera Srbije, 2020)
Komercijalna primena hidrolizata proteina soje još uvek je ograničena zbog male
bioraspoloživosti peptida, gorkog ukusa, higroskopnosti i reaktivnosti u prehrambenim
proizvodima. Cilj ovog istraživanja jeste inkapsulacija ...
Colloid electrohydrodynamics
(Savez hemijskih inženjera, Beograd, 2009)
This brief extracted review presents the recent development in basic and applied science and engineering of finely dispersed particles and related systems in general, but more profound and in-depth treatise are related to ...
