Investigation of the impact of mechanical activation on synthesis of the MgO-TiO2 system
(Savez hemijskih inženjera, Beograd, 2021)
In this study, a mixture of magnesium oxide and titanium dioxide was mechanically activated in order to investigate the possibility of mechanochemical synthesis of magnesium titanate. Mechanical activation was performed ...
Influence of Pr3+ and CO32- Ions Coupled Substitution on Structural, Optical and Antibacterial Properties of Fluorapatite Nanopowders Obtained by Precipitation
(MDPI, Basel, 2021)
Coupled substitution of fluorapatite (FAP) crystal lattice plays an important role in the engineering of optically active nanomaterials. Uniform fluorapatite nanopowders doped with praseodymium (Pr3+) and carbonate (CO32-) ...
DTA/TG analysis of mechanochemicaly activated sodium carbonate
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2021)
Sodium carbonate is a material that is very good sorbent of carbon dioxide from the atmosphere, and it is a reason of it is increasing importance in environmental protection. In order to improve it is sorption characteristics, ...
Fabrication and characterization of manganese ferrite/expanded vermiculite as a magnetic adsorbent of nickel ions
(Belgrade : Serbian society of corrosion and materials protection (UISKOZAM), 2021)
Adsorbents based on magnetic materials are the subject of numerous researches. Beside good magnetism and functional surface, manganese ferrite is unstable and prone to form low mechanical strength agglomerates, which ...
Thermal properties of lithium germanate phosphate glass studied by DTA
(Bor : University of Belgrade, Technical Faculty in Bor, 2021)
The DTA data collected for 22.5Li2O·10Al2O3∙30GeO2∙37.5P2O5 (mol%) glass sample was reported and discussed. The ease of glass formation has been studied. It was determined that the DTA exothermal temperature peaks revealed ...
The influence of the particle size on crystallization of glass powders from the system Li2O-Al2O3-GeO2-P2O5
(University of Belgrade, Technical Faculty in Bor, 2021)
The glass was prepared by standard melt-quenching technique. The crystallization of powder glass from the system Li2O-Al2O3-GeO2-P2O5 was studied. The investigations were performed under non-isothermal and isothermal ...
The clay preliminary testing from municipality area of Rekovac
(Univesity of Belgrade-Technical Faculty in Bor, 2021)
On the territory of Rekovac municipality, geological research has discovered clay deposit "Oparić". The sample was taken from the well core with 9m depth, then stirred with water and sifted by wet process on a sieve with ...
Upgrading of a fuel potential of waste biomass via hydrothermal carbonization
(Zvornik : University of East Sarajevo, Faculty of Technology, 2021)
"
In recent decades, the massive exploitation of fossil fuels, with a detrimental impact on the environment, caused a growing demand for the production of energies from renewable sources. One of the researchers' solutions ...
Dissolution of glass made from coal fly ash, glass cullet and calcium carbonate
(Bor : University of Belgrade, Technical Faculty in Bor, 2021)
Coal fly ash represents huge ecological problem and its reutilization should be considered. Vitrification of coal fly ash could be one of the solutions. The glass was obtained by melting a mixture of coal fly ash, glass ...
Thermal kinetic analysis of the spent mushroom substrate and hydrochar
(Szeged : University of Szeged, 2021)
A carbon-rich product, hydrochar, was synthesized by hydrothermal carbonization (HTC) of spent mushroom substrate (SMS), at temperature of 260 °C. The thermal kinetic analysis has shown that hydrothermally treatment improve ...
