Geochemical investigation as a tool in the determination of the potential hazard for soil contamination (Kremna Basin, Serbia)
(Belgrade : Serbian Chemical Society, 2015)
The geochemical composition of the soils and underlying sediments in the Kremna Basin was investigated. The aim was to assess whether the observed heavy metal concentrations in the soil samples represent geogenic or ...
Drmno lignite field (Kostolac Basin, Serbia): Origin and palaeoenvironmental implications from petrological and organic geochemical studies / Ligniti ležišta Drmno (basen Kostolac) - poreklo i paleouslovi stvaranja na osnovu petrografskih i organsko-geohemijskih istraživanja
(Serbian Chemical Soc, Belgrade, 2012)
The objective of the study was to determine the origin and to reconstruct the geological evolution of lignites from the Drmno field (Kostolac Basin, Serbia). For this purpose, petrological and organic geochemical analyses ...
Flavonoids from flowers of Cephalaria pastricenis and their antiradical activity / Flavonoidi iz cvetova Cephalaria pastricensis i njihova antiradikalska aktivnost
(Serbian Chemical Society, 2004)
Two flavonoid glycosides 1 and 2 having the luteolin structure were isolated from flowers of the endemic plant species Cephalaria pastricensis. They were identified by 1H and 13C NMR, as well as UV/Vis spectroscopy. The ...
Heavy metals in Neogene sedimentary rocks as a potential geogenic hazard for sediment, soil, and surface and groundwater contamination (eastern Posavina and the Lopare Basin, Bosnia and Herzegovina)
(Serbian Chemical Soc, Belgrade, 2015)
The influence of geochemical processes (weathering, erosion and dilution) of the Internal Dinarides to the Posavina Neogene Basin and their implication to the pollution of the Sava River sediments at four sampling sites ...
Phenolic and mineral profile of Balkan indigenous apple and pear cultivars
(Serbian Chemical Society, 2016)
The aim of this study was the determination of phenolic compounds, and mineral nutrients in the pulp and peel obtained from Balkan indigenous apple and pear cultivars. The phenolic composition, assessed by HPLC-DAD and ...
Characterisation of lignite lithotypes from the "Kovin" deposit (Serbia) - Implications from petrographic, biomarker and isotopic analysis
(Serbian Chemical Soc, Belgrade, 2017)
Four lignite lithotypes (matrix coal, xylite-rich coal, mixture of matrix and mineral-rich coal and mixture of matrix and xylite-rich coal), originating from the Kovin deposit, were investigated in detail. The paper was ...
Consistent force field for metalloporphyrins / Konzistentno polje sila za metaloporfirine
(Serbian Chemical Soc, Belgrade, 2010)
Molecular mechanics (MM) calculations to analyze the puckering of metalloporphyrins isolated and adsorbed on a graphite layer (0001) as a function of metal ion size and the peripheral substitution are presented. The ...
Synthesis, antimicrobial and antioxidative activity of some new isatin derivatives
(Serbian Chemical Society, 2014)
The isatin derivatives, Schiff bases, were synthesized by the reaction of isatin and various substituted primary amines and characterized by several spectroscopic methods. Investigation of the antimicrobial activity of the ...
Breaking news: Empirical formulas, molar masses, biosynthesis reactions, and thermodynamic properties of virus particles, biosynthesis and binding of Omicron JN.1 variant of SARS-CoV-2 / Ударне вести: емпиријске формуле, моларне масе, реакције биосинтезе и термодинамичке особине вирусних честица, биосинтезе и везивања Omicron JN.1 варијанте SARS-CoV-2
(Serbian Chemical Society, 2024)
Breaking news are usually disturbing. Natural disasters, wars, epidemics etc. are reported as breaking news. This paper reports a decreased danger of spreading of epidemics caused by the JN.1 variant, since analyses indicate ...
π–π interactions in structural stability: Role in superoxide dismutases / Испитивање улоге катјон–π интеракција у активним центрима супероксид-дисмутаза
(Belgrade : Serbian Chemical Society, 2023)
In the present work, the influences of π–π interactions in superoxide
dismutase (SOD) active centers were analyzed. The majority of the aromatic
residues are involved in π–π interactions. Predominant type of interacting ...
