Influence of chain length and degree of branching of alcohol plus chlorobenzene mixtures on determination and modelling of V-E by CEOS and CEOS/G(E) mixing rules
(Elsevier Science Bv, Amsterdam, 2008)
The densities of binary mixtures of (1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol+chlorobenzene) have been measured at temperatures 288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K and atmospheric pressure while ...
Solid-state NMR study of an open-framework aluminophosphate-oxalate hybrid
(Amer Chemical Soc, Washington, 2003)
Short-range order within a novel aluminophosphate-oxalate hybrid material with the unit cell formula CH2(NH3)CH(NH3)CH3Al4P6O20(OH)(4)(C2O4)H2O was studied by multinuclear solid-state NMR measurements. The C-13, Al-27, and ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(substituted phenylmethylene)-3-and-4-aminobenzoic acids
(Elsevier Science Bv, Amsterdam, 2005)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenylmethylene)-3- and -4-aminobenzoic acids having a wide range of substituent effects, were determined in deuterated DMSO solution. Good Hammett ...
NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene / NMR analiza 2-(2',3'-dihidro-1'H-inden-1'-il)-1H-indena
(Serbian Chemical Society, Belgrade, 2001)
1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling ...
Nonlinear dynamics of brewing yeast cell growth in alginate micro-beads
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
The nonlinear dynamics of brewing yeast cell growth in porous Ca-alginate matrices is considered experimentally and theoretically. The applications of alginate matrices include the reduction of internal mass transfer ...

(Savez inženjera metalurgije Srbije, Beograd, 2003)
Amorphous covalent Si-C-N ceramics have been synthesized by pyrolysis polysilazanes. This part of experiment was done in Institute für Nichtmetallische Anorganische Materialien, Universitaet Stuttgart, Germany. Ceramics ...
Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...
Smart hydrogels based on itaconic acid for biomedical application / Inteligentni hidrogelovi na bazi itakonske kiseline za biomedicinsku primenu
(Association of Chemical Engineers of Serbia, 2009)
pH and temperature sensitive hydrogels, based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) copolymers, were prepared by gamma irradiation and characterized in order to examine their potential use in biomedical ...
XPS and contact angle study of cotton surface oxidation by catalytic bleaching
(Elsevier Science Bv, Amsterdam, 2007)
Surface chemistry and wetting properties of cotton fibres as affected by catalytic bleaching have been investigated. Two types of cotton fabric have been analysed: the regular and a model cotton fabric. In the regular - ...
Chitosan/acid dye interactions in wool dyeing system
(Elsevier Sci Ltd, Oxford, 2005)
This study assesses the interactions that could occur during dyeing of the chitosan treated wool fibres on basis of the spectrophotometric study, by measuring the absorbance values of the solutions containing dye and ...
