Synthesis of novel piperazino-alkyl-1H-benzo[d]imidazole derivates and assessment of their interactions with the D2 dopamine receptor
(Serbian Chemical Society, 2019)
A total of 14 novel arylpiperazines were synthesized, and pharmacologically evaluated by measuring their affinities towards the D2 dopamine receptor (D2DR) in a [3H]spiperone competition assay. All herein described compounds ...
The particle size distribution (PSD) as criteria for comparison of silver powders obtained by different methods of synthesis and by conditions of electrolysis
(Bor : Technical Faculty, 2018)
Silver powders produced by both electrochemical (galvanostatic (DC) and potentiostatic (POT) regimes of electrolysis) and chemical processes were examined by scanning electron microscope, and particle size distribution ...
Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
Hydride reduction of B-norcholestane 5α,6α-epoxide / Hidridna redukcija B-norholestan 5α,6α-epoksida
(Serbian Chemical Society, 2002)
B-Norcholestane epoxide 2 is reduced with lithium aluminium hydride to give either the 3β,6α-diol 3 or the corresponding 3β,5α-diol 4, depending on the quality of the reducing reagent employed. Aplausible mechanistic ...
The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate and the assignment of the configuration of its acetoxy derivatives / Kristalna struktura 14-okso-13,14-seko-5α-holest-13(18)-en-3β-il-acetata i određivanje konfiguracije njegovih acetoksi derivata
(Serbian Chemical Society, 2000)
The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate (2), obtained (in addition to the (E)-Δ12-isomer 3) by oxidative fragmentation of the C(13)-C(14) bond of 14α-hydroxy-5α-cholestan-3β-yl acetate ...
Surface and thermomechanical characterization of polyurethane networks based on poly(dimethylsiloxane) and hyperbranched polyester
(Budapest University of Technology, 2013)
Two series of polyurethane (PU) networks based on Boltorn (R) hyperbranched polyester (HBP) and hydroxyethoxy propyl terminated poly(dimethylsiloxane) (EO-PDMS) or hydroxy propyl terminated poly(dimethylsiloxane) (HP-PDMS), ...
Distribution and provenance of heavy metals in sediments of the Vrbas River, Bosnia and Herzegovina / Примена индекса загађења у одређивању просторних и временских разлика у концентрацији тешких метала у седиментима реке Врбас, (Бања Лука, Босна и Херцеговина)
(Serbian Chemical Society, 2022)
Heavy metals are naturally occurring elements, but they are regarded as significant environmental pollutants due to their high density and high toxicity even at low concentrations. The aim of this paper is the evaluation ...
5S Elements as steps to bridge the gap in transmitter manufacturing process / 5S elementi kao koraci za premošćivanje procepa u procesu prozvodnje transmitera
(Zrenjanin: University of Novi Sad - 'Mihajlo Pupin' Technical Faculty, 2019)
In this paper, GAP analysis and 5S tool are applied in the case of realization of a compact pressure
transmitter. GAP analysis, combined with the 5S tool, can qualitatively indicate the critical points
in the manufacturing, ...
