Polysaccharide-fullerene supramolecular hybrids: Synthesis, characterization and antioxidant activity
(Elsevier, 2020)
An efficient encapsulation of the fullerene into two hydrophobized and one native polysaccharide provided water soluble supramolecular hybrids. After covalent modification of polysaccharides by cholesterol, noncovalent ...
Influence of surface morphology on methanol oxidation at a glassy carbon-supported Pt catalyst / Uticaj površinske morfologije na oksidaciju metanola na platinskim katalizatorima sa podlogom od staklastog ugljenika
(Serbian Chemical Society, 2008)
Platinum supported on glassy carbon (GC) was used as a model system for studying the influence of the surface morphology of a Pt catalyst on methanol oxidation in alkaline and acidic solutions. Platinum was deposited by ...
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 ...
Water quality as one of the possible causative agents of corrosion in thermal power plants / Kvalitet vode kao jedan od mogućih uzročnika korozije u termoenergetskim postrojenjima
(Belgrade, Serbia : Engineering Society for Corrosion, 2010)
Damage and cancellations of thermal power plants in large numbers are caused due to an inadequate quality of feed water, which occur due to different types of corrosion processes. Water is a good solvent and its chemical ...
Optimization of process of the honeycomb-like structure formation by the regime of reversing current (RC) in the second range
(Springer-Verlag, 2020)
Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been
investigated. Morphological and structural characteristics of this electrode type obtained by various ...
Promotional effect of Sn-ad on the ethanol oxidation at Pt3Sn/C catalyst
(Elsevier Science Inc, New York, 2009)
Oxidation of ethanol was studied at Sn-ad modified and unmodified Pt3Sn/C and Pt/C catalysts. Pt3Sn/C and Pt/C catalysts were characterized by XRD. Potentiodynamic and chronoamperometric measurements were used to establish ...
Kinetic Analytical Method for Determination of Uric Acid in Human Urine using Analyte Pulse Perturbation Technique
(Sociedade Brasileira de Química, 2012)
Simple and reliable novel methods for the determination of uric acid (UA) are proposed and validated. For quantitative determination of UA, two matrices were used: the Bray-Liebhafsky (BL) oscillatory reaction in a stable ...
Distribution of major and trace elements in the Kovin lignite (Serbia)
(Institut za Geoloska Istrazivanja, 2019)
A geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. The Kovin lignite is characterized by high moisture content, medium to high ash yield, ...
Fractionation, Mobility, and Contamination Assessment of Potentially Toxic Metals in Urban Soils in Four Industrial Serbian Cities
(Springer, New York, 2018)
The main soil properties, concentrations of selected elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), and the chemical speciation of each element were determined in urban soil samples taken from urban parks in four Serbian ...
Methanol oxidation at platinum electrodes in alkaline solution: comparison between supported catalysts and model system
(Elsevier, 2004)
Methanol oxidation was studied in 0.1 M NaOH at supported Pt electrodes, and compared with the single crystal Pt electrodes, Pt(1 1 1), Pt(1 1 0) and Pt(3 3 2), chosen as model systems, and with a polycrystalline Pt ...
