Functionalization of polyester fabrics with alginates and TiO2 nanoparticles
(Elsevier Sci Ltd, Oxford, 2010)
This study was aimed to investigate the possibility of engineering the multifunctional textile nanocomposite material based on the polyester fabric modified with natural polysaccharide alginate and colloidal TiO2 nanoparticles. ...
Effect of hemicelluloses and lignin on the sorption and electric properties of hemp fibers
(Elsevier Science Bv, Amsterdam, 2010)
This study investigated the influence of hemicelluloses and lignin removal on the sorption and electric properties, as well as fineness of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin ...
Liquid metal/ceramic interfaces in dental practice and jewellery manufacturing
(Institute of Metals and Technology, 2010)
Metal-ceramic fusing has been the essential step in obtaining materials that benefit from both ceramic and metal constituents. i e where the combined properties of metal and ceramic layers are desirable When considering ...
Production of lactic acid from corn thin stillage using Lactobacillus rhamnosus ATCC 7469
(Технолошко-металуршки факултет, Београд, 2010)
The lactic acid production from corn thin stillage using Lactobacillus rhamnosus ATCC 7469 in a batch system was studied. The fermentation temperature was optimized taking into account lactic acid production and glucose ...
Sodium periodate oxidized cotton yarn as carrier for immobilization of trypsin
(Elsevier Sci Ltd, Oxford, 2010)
Cotton yarn was first oxidized by sodium periodate to introduce aldehyde groups which were able to react with amino groups of trypsin to form Schiff's base, and result in cotton yarn immobilized trypsin. The effect of ...
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 ...
Encapsulation of probiotics for use in food products
(Springer, 2010)
The history of the role of probiotics for human health is one century old and several definitions have been derived hitherto. One of them, launched by Huis in’t Veld and Havenaar (1991) defines probiotics as being “mono ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Elsevier, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H2 oxidation reaction (HOR) at MoOx-Pt electrode in 0.5 mol dm-3 HClO4 saturated with H 2 containing 100 ppm CO, was examined on rotating disc electrode ...
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 ...
