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 ...
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 ...
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 ...
Унапређивање хемијске писмености ученика основних школа кроз контекстуални приступ обради наставне јединице Алкани
(Учитељски факултет Универзитета у Београду, 2022)
Органска хемија представља есенцијални део свакодневног живота, али претходна истраживања указују да традиционална настава органске хемије, фокусирана на трансмисију академских знања, недовољно подстиче развој ученичке ...
Synthesis and characterization of co-mo bimetallic carbides
(International Institute for the Science of Sintering (IISS), 2019)
Co-Mo carbides were prepared by impregnation with aqueous solution of metal salts and sucrose into ordered mesoporous SBA-15 silica template using carbothermal hydrogen reduction. Bimetallic Co-Mo carbide obtained by using ...
3D-QSAR study of adenosine 5'-phosphosulfate (APS) analouges as ligands for APS reductase
(Belgrade : Serbian Chemical Society, 2021)
Metabolism of sulfur (sulfur assimilation pathway, SAP) is one of the key pathways for the pathogenesis and survival of persistant bacteria, such as Mycobacterium tuberculosis (Mtb), in the latent period. Adenosine ...
