Intramolecular Barbier reaction in water: Cyclopentane and cyclohexane ring closure / Intramolekulska Barbier-ova reakcija u vodi - sinteza petočlanih i šestočlanih prstenova
(Serbian Chemical Society, 2002)
Zinc or indium promoted intramolecular Barbier reactions of aldehydes containing a suitably positioned allylic or propargylic halide unit afford unsaturated cyclic alcohols in moderate yields.
Volatile Components from Old Plum Brandies / Hlapljivi sastojci šljivovice
(Croatia : University of Zagreb, 2005)
Gas chromatography and GC/MS methods were used to detect volatile components of three home-made natural old plum brandy samples and one sample of industrially-produced plum brandy. Gas chromatography and gas chromatography-mass ...
Synthesis and biological evaluation of 5-substituted derivatives of benzimidazole
(Serbian Chemical Soc, Belgrade, 2014)
A series of eight novel 5-substituted derivatives of benzimidazole was synthesized by condensation of the corresponding diamine with ethyl 4-[4-(2-chlorophenyl)piperazin-1-yl]butanoate in refluxing 4 M hydrochloric acid. ...
Fabrication of Sio2-based microcantilevers by anisotropic chemical etching of (100) single crystal Si / Izrada mikrogredica od SiO2 anizotropnim hemijskim nagrizanjem na monokristalnom silicijumu (100) orijentacije
(Serbian Chemical Society, 2007)
The undercutting process of thermal SiO2 microcantilevers with different orientations on (100) Si wafer was studied. The silicon substrate was removed by anisotropic chemical etching with a 25 wt. % aqueous solution of ...
Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Синтеза и модификација кополимера анхидрида итаконске киселине и метил-метакрилата
(Belgrade : Serbian Chemical Society, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60°C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
Unusually sluggish microemulsion system with water, toluene and a technical branched alkyl polyethoxylate
(Serbia : Association of Chemical Engineers of Serbia, 2015)
Microemulsion systems with water, toluene and nonionic surfactants are interesting for application due to the excellent solvent properties of aromatic hydrocarbons. In this study, the pseudo-binary phase diagram (“fish-diagram”) ...
Effect of the electrolysis regime on the structural characteristics of honeycomb-like electrodes
(Soc Chemists Technologists Madeconia, Skopje, 2013)
The effect of different current regimes of electrolysis on the micro- and nanostructural characteristics of open porous structures was examined by the analysis of honeycomb-like copper electrodes obtained by constant ...
The effect of the intensity of parasitic infection with Strongyloides papillosus and albendazole therapy on biochemical parameters in sheep blood / Uticaj intenziteta parazitske infekcije sa Strongyloides papillosus i terapije albendazolom na biohemijske parametre u krvi ovaca
(Veterinary Faculty, Univ Beogradu, Belgrade, 2013)
The aim of this report was to study the biochemical parameters in sheep blood under conditions of various intensities of parasitic infection with Strongyloides papillosus, as well as after therapy with albendazole (ABZ). ...
Chemical modification of the lectin of the marine coral Gerardia savaglia by marine quinone avarone / Hemijske modifikacije lektina morskog korala Gerardia savaglia morskim hinonom avaronom
(Serbian Chemical Soc, Belgrade, 2007)
The quinone avarone, isolated from the marine sponge Dysidea avara, possesses the ability to chemically modify proteins. In this work, modification of lectin isolated from the coral Gerardia savaglia by avarone was examined. ...
