Use of cyclic voltammetry to determine the antioxidant capacity of berry fruits: Correlation with spectrophotometric assays
(INT SOC HORTICULTURAL SCIENCE-ISHS, 2019)
Background of the study – Among fruits, berry fruits contain a very large complex of chemical compounds that are responsible for their antioxidant properties. As far as we know there is no data available from cyclic ...
Some examples of interactions between certain rare earth elements and soil
(Belgrade : Serbian Chemical Society, 2022)
The rare earth elements represent an increasingly more and more
important industrial resource. The increased use may result in waste generation, and their impact upon the environment quality has not been studied
sufficiently. ...
Oxidized humic acids from the soil of heat power plant / Oksidovane huminske kiseline iz toplane
(Serbia : Serbian Chemical Society, 2020)
Humic acids isolated from the soil of a heat power plant (HA-E) contaminated with oil were analyzed by Fourier transform infrared spectroscopy (FTIR). In comparison with a humic acids standard (HA-S), a lack of an intense ...
Electrooxidation of 1-propanol on the mixture of nanoparticles of Pt and RuO2
(Springer Link, 2021)
The catalyst composed of a mixture of nanocrystals of metallic Pt and rutile RuO2 was prepared by a thermal procedure on a titanium substrate. An effect of the mixture composition on its microstructure, surface properties, ...
Effect of deposition current density and annealing temperature on the microstructure and magnetic properties of nanostructured ni-fe-w-cu alloys
(Science of Sintering, 2019)
Ni-Fe-W-Cu alloy powders were obtained by electrodeposition from an ammonium citrate bath at current densities ranging between 70 and 600 mA cm-2. As the deposition current density increased, the contents of Fe and W in ...
The effect of the composition of the alloy of ruo2 and pt nanocrystals on intermediate adsorption during methanol oxidation
(Academia Romana, 2020)
A catalytic coating composed of a mixture of RuO2 and Pt
nanocrystals was prepared by a thermal procedure on a titanium
substrate and used for the electrochemical oxidation of methanol.
The adsorption of the intermediate ...
Methanol Electrooxidation on Pt/RuO2 Catalyst
(Springer, 2021)
A catalytic coating, composed of a mixture of nanocrystals of Pt and RuO2, used for oxidation of CH3OH, was formed by the thermal procedure. The size of the RuO2 nanocrystals was increasing and of Pt was decreasing with ...
Hydrogen Adsorption Process In Nanocrystalline Nuclear Graphite
(Belgrade : Vinča Institute of Nuclear Sciences, 2022)
Kinetics and mechanism of hydrogen adsorption in as-obtained and ground nuclear graphite
Wendelstein 7-X are examined. In the first time interval the adsorption process is determined
by dissociation of the hydrogen ...
Significance of infrared spectroscopic branching factor for investigation of structural characteristics of alkanes, geochemical properties and viscosity of oils: Scientific paper
(Belgrade : Serbian Chemical Society, 2022)
A detailed investigation of significance of the infrared (IR) spectroscopic branching factor (СН2/СН3; the ratio of methylene and methyl group peak heights at 2917–2921 and 2951–2954 cm-1, respectively in the IR spectra) ...
Development of conceptual understanding of physical and chemical changes at the macroscopic, submicroscopic and symbolic level: a cross-age study
(The Faculty of Teacher Education of the University of Zagreb, Croatia, 2022)
In order to explain the development of understanding of chemical concepts at the
macroscopic, submicroscopic and symbolic level over time, models of the expanding
triangle and rising iceberg are proposed. In order to ...
