Poly(urethane-siloxane)s based on hyperbranched polyester as crosslinking agent: Synthesis and characterization / Poli(uretan-siloksani) na bazi hiperrazgranatog poliestra kao umreživača - sinteza i karakterizacija
(Serbian Chemical Society, 2012)
A series of novel polyurethane crosslinked structures (PUs) was prepared from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO), 4,4'-methylenediphenyl diisocyanate and Boltorn ® hyperbranched ...
Production and characterization of rhamnolipids from Pseudomonas aeruginosa san-ai / Produkcija i karakterizacija ramnolipida soja Pseudomonas aeruginosa san-ai
(Serbian Chemical Society, 2012)
The production and characteristics of rhamnolipid biosurfactant obtained by the strain Pseudomonas aeruginosa san-ai were investigated. With regard to the carbon and nitrogen sources, several media were tested to enhance ...
Modeling of motor fuel consumption in Serbia with projection to 2025 / Modelovanje potrošnje motornih goriva u Srbiji sa projekcijama do 2025. godine
(Association of Chemical Engineers of Serbia, 2012)
This study is based on the application of mathematical methods of statistical analysis that can be used to predict the development of motor fuel consumption in the Republic of Serbia. It is based on the linear dependence ...
Catalysis of Hydrogen Evolution on Au(111) Modified by Spontaneously Deposited Pd Nanoislands
(Springer, New York, 2012)
Hydrogen evolution reaction was studied on Au(111) modified by palladium spontaneously deposited on the Au(111) surface from (1 mM PdSO4 center dot 2 H2O + 0.5 M H2SO4) solution at a submonolayer coverage. Number and size ...
Formation of Magnetic Microstructure of the Nanosized NiFe2O4 Synthesized Via Solid-State Reaction
(International Institute for the Science of Sintering, Beograd, 2012)
Magnetic NiFe2O4 structure formation was studied through structural, compositional and magnetic characterization of obtained reaction products of a simple, high yielding and low-cost solid-state reaction. Initial annealing ...
The study of Zn-Co alloy coatings electrochemically deposited by pulse current / Ispitivanje prevlaka Zn-Co legura dobijenih pulsirajućom strujom
(Association of Chemical Engineers of Serbia, 2012)
The electrochemical deposition by pulse current of Zn-Co alloy coatings on steel was examined, with the aim to find out whether pulse plating could produce alloys that could offer a better corrosion protection. The influence ...
Decolorization of Reactive Black 5 using a dielectric barrier discharge in the presence of inorganic salts / Obezbojavanje reaktivnog crnog 5 pomoću dielektričnog barijernog pražnjenja u prisustvu neorganskih soli
(Serbian Chemical Soc, Belgrade, 2012)
Inorganic salts improve the coloration of textiles, which increases the pollution load of dye-house effluent in general. Decolorization of the reactive textile dye C.I. Reactive Black 5 was studied using Advanced Oxidation ...
Response surface optimization for activation of bentonite using microwave irradiation
(Clay Minerals Soc, Chantilly, 2012)
Microwave irradiation as a means for heating bentonites during acid activation has been investigated in the past but it has never been optimized for industrial applications. The purpose of this study was to apply a factorial ...
The effect of polar solvents on the synthesis of poly(urethane-urea-siloxane)s / Uticaj polarnih rastvarača na sintezu poli(uretan-urea-siloksana)
