Biodegradation of Isoprenoids, Steranes, Terpanes, and Phenanthrenes During In Situ Bioremediation of Petroleum-Contaminated Groundwater
(Wiley, Hoboken, 2017)
The objective of this study was to stimulate microbial biodegradation of petroleum pollution in groundwater and to analyze changes in the abundance and distribution of organic compounds detectable in petroleum. Bioremediation ...
Kinetic Analysis of Nonisothermal Reduction of Silica-Supported Nickel Catalyst Precursors in a Hydrogen Atmosphere
(Philadelphia : Taylor & Francis Inc, 2016)
A series of silica-supported nickel catalyst precursors was synthesized with different SiO2/Ni molar ratios. Reduction of Ni catalyst precursors with different SiO2/Ni molar ratios under a hydrogen atmosphere was investigated ...
Synthesis and spectroscopic properties of large single-crystals of Pb(II), Hg(II) and Sr(II) methanesulfonato 1D coordination polymers
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Three new 1D coordination polymers, [Pb-2(CH3SO3)(4)(H2O)(2)](n), [Hg(CH3SO3)(2)(H2O)(2)](n) and [Sr(CH3SO3)(2)(H2O)](n), were synthesized as large single crystals. The crystals were analyzed and characterized by the means ...
Persistent organic pollutants (POPs) in sediments from river and artificial lakes in Serbia
(Elsevier, 2017)
In an attempt to evaluate the toxicological condition of the most important river and artificial lakes in Serbia, 52 grab-samples were collected from different locations. Sediment samples were analyzed for PCBs (PCB 28, ...
Synthesis and biological activity of amino acid derivatives of avarone and its model compound
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
A series of eighteen derivatives of marine sesquiterpene quinone avarone and its model system tert-butylquinone with amino acids has been synthesized by nucleophilic addition of amino acids to the quinones. In vitro cytotoxic ...
Study of potential harmful elements (arsenic, mercury and selenium) in surface sediments from Serbian rivers and artificial lakes
(Elsevier, 2017)
This investigation examines surface sediment samples from rivers and artificial lakes (Serbia) to quantify levels of potentially harmful elements (As, Hg, and Se) and several ancillary elements (Al, Fe, Mn, Ca, Mg, C, H, ...
Chemo-protective and regenerative effects of diarylheptanoids from the bark of black alder (Alnus glutinosa) in human normal keratinocytes
(Elsevier, 2015)
Medicinal plants are recognized from ancient times as a source of diverse therapeutic agents and many of them are used as dietary supplements. Comprehensive approaches are needed that would identify bioactive components ...
Plasmonic sensors in multi-analyte environment: Rate constants and transient analysis
(Inst Chemical Engineers, Rugby, 2014)
This paper investigates multicomponent gas adsorption at the active surface of plasmonic chemical sensors and shows that there are situations where transients in a single sensor element can be used for simultaneous detection ...
Reactions of superoxide dismutases with HS-/H2S and superoxide radical anion: An in vitro EPR study
(Academic Press Inc Elsevier Science, San Diego, 2015)
Interactions of hydrogen sulfide (HS-/H2S), a reducing signaling species, with superoxide dimutases (SOD) are poorly understood. We applied low-T EPR spectroscopy to examine the effects of HS-/H2S and superoxide radical ...
Optical evidence of magnetic field-induced ferrofluid aggregation: Comparison of cobalt ferrite, magnetite, and magnesium ferrite
(Elsevier, 2019)
Light-transmitting measurements of white light and a consequentially chosen laser beam of 655 nm propagatingthrough citrate- and oleate-coated CoFe2O4, FeFe2O4, and MgFe2O4 nanoparticles under the influence of anexternal ...
