Fine structural analysis of the fungal polysaccharide pullulan elaborated by Aureobasidium pullulans, CH-1 strain / Fina strukturna analiza fungalnog polisaharida pululana dobijenog pomoću Aureobasidium pullulans, soj CH-1
(Serbian Chemical Society, 2001)
The structure of pullulan, the extracellular α-D-glucan elaborated by the yeast-like fungus Aureobasidium pullulans, may be described as a linear α-D-glucan consisting of maltotriosyl repeat units connected terminally by ...
Oil pollutants in alluvial sediments - influence of the intensity of contact with ground waters on the effect of microorganisms / Naftni zagađivači u aluvijalnim sedimentima - uticaj intenziteta kontakta sa podzemnim vodama na dejstvo mikroorganizama
(Serbian Chemical Soc, Belgrade, 2003)
The influence of the intensity of interaction between oil pollutants and ground waters in alluvial sediments on the effect of microbial activity was investigated in this work. The study was based on a comparison of detailed ...
Analysis of amphetamines illegally produced in Serbia / Анализа амфетамина илегално произведеног у Србији
(Belgrade : Serbian Chemical Society, 2008)
Forensic practice in the Republic of Serbia faced the illegal production of amphetamine for the first time in 2003. This paper presents the results of the chemical characterization of 32 batches of amphetamine samples from ...

(Acta veterinaria, 2006)
The effect of some membrane active ionophoric antibiotics on the amplitude of contractions of isolated rat heart right ventricle was studied. The effects of polyether nigericin, polyene amphotericin B and peptide antibiotic ...
Structure and stereochemistry of electrochemically synthesized poly-(l-naphthylamine) from neutral aceto- nitrile solution / Struktura i stereohemija poli-(1-naftilamina) elektrohemijski sintetisanog u neutralnom acetonitrilnom rastvoru
(Serbian Chemical Society, 2002)
Poly-(1-naphthylamine) films were synthesized potentiodinamically and potentiostatically from 1-naphthylamine in neutral acetonitrile medium using a platinum electrode. These polymer films were investigated by infrared ...
Surface plasmon - Polariton assisted metal-dielectric multilayers as passband filters for ultraviolet range
(Polish Academy of Sciences, 2007)
We designed and fabricated metal-dielectric multilayers intended for passband filters in the ultraviolet range. We determined the dispersion characteristics by the Bloch approach to evanescent wave resonant coupling and ...
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 ...
