Bioremediation of river sediment polluted with polychlorinated biphenyls: A laboratory study / Биодеградација полихлорованих бифенила у речном седименту: лабораторијска студија
(Belgrade : Serbian Chemical Society, 2022)
Persistent organic pollutants (POPs) are lipophilic, constant and bioaccumulative toxic compounds. In general, they are considered resistant to biological, photolytic, and chemical degradation with polychlorinated biphenyls ...
Achillea clypeolata sibth. & sm. essential oil composition and qsrr model for predicting retention indices / Hemijski sastav etarskog ulja Achillea clypeolata Sibth. & Sm. И QSRR model za predviđanje retencionog vremena
(Belgrade : Serbian Chemical Society, 2021)
The aim of this study was the prediction model of retention indices of compounds from the aboveground parts of Achillea clypeolata Sibth. & Sm. essential oil, obtained by hydrodistillation and analysed by GC-MS. The ...
DNA protective activity of triterpenoids isolated from medicinal mushroom Fomitopsis betulina / DNK protektivna aktivnost triterpena izolovanih iz medicinske gljive Fomitopsis betulina
(Belgrade : Serbian Chemical Society, 2021)
Eleven 31-methylenlanostane triterpenoids, i.e., seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina, were tested for in vitro ...
Al-Pd alloy formation by aluminium underpotential deposition onto palladium from chloroaluminate melt
(Belgrade : ESG, 2021)
The possibility of electrochemical underpotential deposition of aluminium onto palladium from equimolar AlCl3+NaCl melts at temperatures between 200 ° and 300 °C was investigated. Electrochemical techniques used were cyclic ...
Assessment of density functional approximations for calculation of exchange coupling constants in thiocyanato and cyanato double bridged binuclear Ni(II) complexes / Испитивање апроксимативних функционала густине за израчунавање константи купловања у двоструко премошћеним тиоцијанато и цијанато бинуклеарним Ni(II) kомплексима
(Belgrade : Serbian Chemical Society, 2020)
In the present work, we examine the magnetic properties of 8 "end-to-end" thiocyanato, and 3 "end-to-end" cyanato double bridged Ni(II) binuclear complexes. Thiocyanato complexes are weakly ferromagnetic. Cyanato bridged ...
Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...
Early-Middle Miocene paleoenvironmental and paleoclimate changes in the Toplica Basin (Serbia) inferred from plant biomarkers, biochemical and elemental geochemical proxies
(Central Library of the Slovak Academy of Sciences, 2021)
The study investigates the influence of alluvial-lacustrine processes and paleoclimate variations on the distribution of terpenoids and unsubstituted Polycyclic Aromatic Hydrocarbons (PAHs). The XRF, ICP-MS, Rock-Eval, and ...
Amide–π interactions in active centres of superoxide dismutase / Amid-–π interakcije u aktivnom centru superoksid-dismutaza
(Belgrade : Serbian Chemical Society, 2021)
PaiIn this work, the influence of amide–π interactions on stability and properties of superoxide dismutase (SOD) active centres was analysed. In the data set of 43 proteins, 5017 amide–π interactions were observed, and ...
Controllable arrangement of integrated obstacles in silicon microchannels etched in 25 wt % TMAH / Kontrolisan raspored integrisanih prepreka u silicijumskim mikrokanalima nagrizanim u 25 mas.% rastvoru tetrametilamonijum hidroksida
(Association of Chemical Engeneers of Serbia, 2021)
In this paper, fabrication of silicon microchannels with integrated obstacles by using 25 wt.% tetramethylammonium hydroxide (TMAH) aqueous solution at the temperature of 80 C is presented and ...
Investigations on the role of cation–pi interactions in active centres of superoxide dismutase / Испитивање улоге катјон–π интеракција у активним центрима супероксид-дисмутаза
(Serbian Chemical Society, 2022)
In this study, we have analysed the influence of cation–π interactions on stability and properties of superoxide dismutase (SOD) active centres. The number of interactions formed by arginine is higher than by lysine in the ...
