Microstructure, roughness, and corrosion resistance of X5CrNi18-10 austenite stainless steel welded joint / X Mikrostruktura , hrapavost i otpornost na koroziju zavarenog spoja austenitnog nerđajućeg čelika X5CrNi18-10
(Belgrade : Serbian Chemical Society, 2021)
The influence of the microstructure of X5CrNi18-10 stainless steel welded joint on its resistance to general, pitting, and intergranular corrosion was analyzed. The structure of weld metal, heat affected zone (HAZ) and ...
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 ...
Flavonoids of the Heartwood of Cotinus coggygria Scop. Showing Protective Effect on Human Lymphocyte DNA
(SAGE Publications, 2021)
In continuation of our study on Cotinus coggygria from Serbia, 10 known flavonoids (1-10) were isolated from the methylene chloride/ methanol extract of the heartwood. They were tested for in vitro protective effect against ...
Nonacosan-10-ol and n-Alkanes in Leaves of Pinus pinaster
(SAGE Publications Inc., 2020)
In leaf cuticular wax of Pinus pinaster, content of nonacosan-10-ol is high (77.1% on average). n-Alkanes ranged from C18 to C35
with the most dominant C29 (24.8%). The carbon preference index (CPItotal) ranged from 3.1 ...
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 ...
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 ...
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 ...
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 ...
Extraction kinetic of some phenolic compounds during Cabernet Sauvignon alcoholic fermentation and antioxidant properties of derived wines / Екстракциона кинетика на некои фенолни соединенија во текот на алкохолната ферментација на грозје од сортата каберне совињон и антиоксидантни својства на добиените вина
(The Society of Chemists and Techonogists of Macedonia, 2020)
In this study, we estimated the usage of Cabernet Sauvignon in microvinifications, obtaining wines with increased phenolic compound content. Kinetic extraction of phenolic compounds during alcoholic fermentation was affected ...
