The use of biological markers in organic geochemical investigations of the origin and geological history of crude oils (I) and in the assessment of oil pollution of rivers and river sediments of Serbia (II). / Употреба биолошких маркера у органско-геохемијским испитивањима порекла и геолошке историје сирових нафти (I) и у процени нафтног загађења река и речних седимената Србије (II)
(Serbian Chemical Society, 2022)
Biological markers (BMs) are organic compounds in oils in which a precursor is known, and during the transformation of organic matter these compounds undergo certain structural and stereochemical changes. Based on the ...
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 ...
New rhodium(III)-ED3AP complex: Crystal structure, characterization and computational chemistry / Нови родијум(iii)-ed3ap комплекс: кристална структура, карактеризација и компјутациона хемија
(Belgrade : Serbian Chemical Society, 2022)
Only one (trans(O5)-Na[Rh(ED3AP)]∙3H2O) of possible two isomers was synthesized and characterized by single crystal X-ray analysis, IR and UV–Vis spectroscopy. Computational analysis of both isomers was performed with three ...

(Belgrade : Serbian chemical society, 2022)
In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia ...
Oxygen Reduction on Glassy Carbon-Supported PdAu Nanoparticles in Perchloric Acid Solution
(Elsevier, 2021)
PdAu/GC nanoparticles obtained by the electrochemical deposition of gold followed by the spontaneous palladium deposition show a remarkable catalytic activity for the oxygen reduction reaction (ORR) in perchloric acid ...
Electrochemical properties of carbonized bentonite / Elektrohemijska svojstva karbonizovanih bentonita
(Serbian Chemical Society, 2022)
Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, ...
