Semi-Interpenetrating Networks Based on Poly(N-isopropyl acrylamide) and Poly(N-vinylpyrrolidone)
(Wiley, Hoboken, 2009)
Three series of novel semi-interpenetrating polymer networks, based on crosslinked poly(N-isopropylacrylamide), PNIPA, and different amounts of the linear poly(N-vinylpyrrolidone), PVP, were synthesized to improve the ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Characterization of sepiolite by inverse gas chromatography at infinite and finite surface coverage
(Elsevier Science Bv, Amsterdam, 2009)
The adsorption properties of sepiolite from Andrici, Serbia, were studied by inverse gas chromatography at zero and finite surface coverage between 483 and 513 K. The thermodynamic parameters (free energy, enthalpy, entropy) ...
A study of the photocatalytic degradation of metamitron in ZnO water suspensions
(Elsevier, Amsterdam, 2009)
The photocatalytic degradation of the herbicide metamitron in water using ZnO under Osram ULTRA-VITALUX (R) lamp light was studied. The effect of the operational parameters such as initial concentration of catalyst, initial ...
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
Investigation of thermodynamic properties and phase equilibria in Ag-In-Sn system / Ispitivanje termodinamičkih veličina i faznih ravnoteža u sistemu Ag-In-Sn
(Savez inženjera i tehničara Srbije, Beograd, 2006)
Lead - free soldering became very popular in the whole world, because of high ecological demands in industry. Most of alternative alloys have high content of tin, and some of them are already used in electronic industry. ...
