Size-segregated trace elements in continental suburban aerosols: seasonal variation and estimation of local, regional, and remote emission sources
(Springer, Dordrecht, 2018)
We have measured trace element contents in suburban aerosols from six size fractions in the range of PM0.27-16 from a background station in Belgrade (Serbia). The distribution and concentration of elements were determined ...
Improvement of epoxy resin properties by incorporation of TiO2 nanoparticles surface modified with gallic acid esters
(Elsevier Sci Ltd, Oxford, 2014)
Epoxy resin/titanium dioxide (epoxy/TiO2) nanocomposites were obtained by incorporation of TiO2 nanoparticles surface modified with gallic acid esters in epoxy resin. TiO2 nanoparticles were obtained by acid catalyzed ...
Response surface optimisation for activation of bentonite with microwave irradiation / Optimalno faktorno planiranje procesa kiselinske aktivacije bentonita u mikrotalasnom polju
(Association of Chemical Engineers of Serbia, 2011)
In this study, the statistical design of the experimental method was applied on the process of acid activation of bentonite with microwave irradiation. The influence of activation parameters (time, acid normality and ...
Perlite as a potential support for nickel catalyst in the process of sunflower oil hydrogenation
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Investigation was conducted in order to elucidate the possibility of using perlite as support for preparation of nickel based precursor catalyst, potentially applicable in vegetable oil hydrogenation process. On three ...
Antimicrobial activity of the diarylheptanoids from the black and green alder
(Soc Botanica Sao Paulo, Sao Paulo, 2015)
Antimicrobial activity of fourteen diarylheptanoids isolated from the bark of black and green alder against twelve bacterial species (five Gram-positive and seven Gram-negative) and eight fungal strains has been reported. ...
Structural modifications of 4-aryl-4-oxo-2-aminylbutanamides and their acetyl- and butyrylcholinesterase inhibitory activity. Investigation of AChE-ligand interactions by docking calculations and molecular dynamics simulations
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2014)
Congeneric set of thirty-eight 4-aryl-4-oxo-2-(N-aryl/cycloalkyl)butanamides has been designed, synthesized and evaluated for acetyl- and butyrylcholinesterase inhibitory activity. Structural variations included cycloalkylamino ...
Origin, organic geochemistry, and estimation of the generation potential of Neogene lacustrine sediments from the Valjevo-Mionica Basin, Serbia
(Maik Nauka/Interperiodica/Springer, New York, 2010)
This paper reports an investigation of 60 samples of lacustrine sedimentary rocks of Neogene age lying at depths of 0-400 m in the Valjevo-Mionica Basin, Serbia. The goal of the study was to determine the origin and type ...
Isolation, Characterization, and In Vitro Cytotoxicity of New Sesquiterpenoids from Achillea clavennae
(Georg Thieme Verlag Kg, Stuttgart, 2014)
Further phytochemical investigation of the aerial parts of Achillea clavennae has resulted in the isolation of three new sesquiterpene lactones: two highly oxygenated germacranolides (1, 2) and the iso-seco-guaianolide ...
Effects of soil properties and fertilization on quality and biological activity of Swiss chard
(International Society for Horticultural Science, 2018)
Swiss chard (Beta vulgaris L. var. cicla) is a leafy vegetable highly consumed in many parts of the world as a very popular ingredient of different diets. The purpose of this study was to evaluate effects of soil properties ...
