Efficiency of phosphorus accumulation by plankton, periphyton developed on submerged artificial substrata and metaphyton: in-situ observation in two shallow ponds
(Springer Science and Business Media LLC, 2020)
Phosphorus overenrichment of shallow ponds prevailing in wetlands leads to their eutrophication causing the collapse of those vulnerable habitats. The potential of phosphorus accumulation by periphyton developed on artificial ...
Genetic and morphological variation in Chara contraria and a taxon morphologically resembling Chara connivens
(Taylor & Francis, 2020)
Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. ...
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 ...
Experimental Investigation of Phase Equilibria in the Bi-Cu-Ge System
(Brazil : SCI FLO, 2021)
Phase diagram of the Bi-Ce-Ge ternary system has been investigated experimentally and thermodynamically extrapolated by using Pandat software. Experimental results were obtained using differential thermal analysis (DTA), ...
Polycyclic aromatic hydrocarbons and their relationship to maturity and paleoenvironmental settings in lacustrine sediments of the Neogene Toplica Basin, Serbia
(Switzerland : Springer Nature, 2021)
The study investigated the influence of maturity, biomass type, and depositional settings on the distribution and relative abundance of polycyclic aromatic hydrocarbons (PAHs) for lacustrine sediments collected from depths ...
Lamiaceae in the treatment of cardiovascular diseases
(Frontiers in Bioscience - Landmark, 2021)
Lamiaceae (Labiatae) are an important group of medicinal plants, which have been used for treating heart disease in traditional medicine for centuries. These mainly aromatic plants are used as essential oils, extracts or ...
Thin-layer chromatography in medicinal chemistry
(Taylor & Francis Inc., 2019)
Among widely used chromatographic methods modern thin-layer chromatography is not only the
simplest to perform but is also considered as respectable analytical method in various phases of
drug discovery and development ...
Carbon Supported PtSn versus PtSnO2 Catalysts in Methanol Oxidation
(Serbia : Electrochemical Science Group, 2021)
Pt, PtSn and PtSnO2 catalysts supported on high surface area carbon synthesized by microwave assisted polyol procedure were tested for methanol oxidation. Based on TGA, EDX and XRD analysis, PtSn/C is composed of Pt 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 ...
