The properties of mechanically activated powders consisting of 17.0 wt% Fe2O3, 4.4 wt% MnCO3, 3.6 wt% ZnO and 75.0 wt% BaTiO3
(Elsevier, 2022)
A novel multiferroic composite material, composed of a mixture of nanocrystals of BaT1-xMexO3 and MeFe12O19 (Me = Zn and Mn) and an amorphous phases of BaTi1-xMexO3, MeFe12O19 and MeFe2O4, is synthetized. The composite ...
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) ...
Introductory concept for teaching chirality – symmetry of the asymmetric (Animation4)
(2023)
Conformation energy diagram of 2,2',3,5',6-pentachloro-1,1'-biphenyl along with the animation of conformational changes are presented. A cursor is pointing a spot on the diagram that corresponds to the conformation animated ...
Introductory concept for teaching chirality – symmetry of the asymmetric (Animation5)
(2023)
Conformation energy diagram of 3'-isopropyl-2-methyl-1,1'-biphenyl along with the animation of conformational changes are presented. A cursor is pointing a spot on the diagram that corresponds to the conformation animated ...
Introductory concept for teaching chirality – symmetry of the asymmetric (Animation3)
(2023)
Conformation energy diagram of 1,2-dibromoethane along with the animation of conformational changes are presented. A cursor is pointing a spot on the diagram that corresponds to the conformation animated at that moment. ...
Introductory concept for teaching chirality – symmetry of the asymmetric (Animation2)
(2023)
Animation of a bending vibration of bromochloromethane. After the animation, models of “bond angle enantiomers” (produced by the vibration) are depicted. Software tools used for creation of the animation are referenced.
Introductory concept for teaching chirality – symmetry of the asymmetric (Animation1)
(2023)
Animation of an asymmetric C-H streching vibration of bromochloromethane. After the animation, models of “bond length enantiomers” (produced by the vibration) are depicted.
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 ...
