Structural and magnetic properties of mechanochemically synthesized LaFe1-xCrxO3 (x = 0.5 and 0.75)
(Belgrade : Materials Research Society of Serbia, 2016)
Perovskite oxides with the composition LaFe1-xCrxO3 (x = 0.5 and 0.75) have been studied. The samples have been prepared using the mechanochemical treatment. A mixture of crystalline La(OH)3, Fe2O3 and Cr2O3 powders in ...
Mechanical properties and microstructure fractal analysis of refractory bauxite concrete
(Belgrade : International Institute for the Science of Sintering, 2015)
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis ...
Choline chloride-based deep eutectic solvents in CaO-catalyzed ethanolysis of expired sunflower oil
(Elsevier, 2018)
Choline chloride (ChCl)-based deep eutectic solvents (DESs) with different amides or polyols as hydrogen bond donors were tested as cosolvents in the ethanolysis of expired sunflower oil catalyzed by either calcined or ...
The influence of alkaline cations on the mechanism and kinetics of dehydration of polymeric phthalatocuprate(II) dihydrates
(Elsevier, 2017)
Thermal dehydration of two heterometallic complexes containing dianion of phthalic acid, pht, Na2[Cu(pht)2] · 2H2O, 1, and K2[Cu(pht)2] · 2H2O, 2, was investigated under non-isothermal conditions. Mechanism and kinetics ...
The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
(Elsevier, 2017)
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...
Structural and magnetic properties of nanocrystalline bismuth manganite obtained by mechanochemical synthesis
(Springer Netherlands, 2011)
We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the ...
In vitro testing of genotoxic and apoptotic potential of two synthesized nanomaterials by DNA fragmentation assay
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Nanomaterials represent a relatively new and developing class of materials that are widely used because of their unique mechanical and physiochemical properties. Due to the particles’ size and the ability to easily enter ...
Fluorination of sodium cobalt oxide: effects on structure and electrochemical performance
(Belgrade : Vinča Institute of Nuclear Sciences, University of BelgradeBelgrade : Hydrogen Economy Initiative Serbia, 2018)
Within this research the possibility of fluorine doping of the P2 type NaxCo02 powder was examined. As fluorine substitution already proved successful in improving cathode performance of layered lithium-based counterparts, ...
Regeneration bone tissue by new nanoparticules system based on hydroxiapatite as systems for local delivery of vitamin D3
(Belgrade : Materials Research Society of Serbia, 2012)
Increased life expectancy in developed countries leads to an increase in the number of musculoskeletal disorders, such as osteoporosis, oasteoratritis thus compromising good dental treatment. There are many drug delivery ...
Novel utilization of fly ash for high-temperature mortars: Phase composition, microstructure and performances correlation
(Hoboken, NJ : John Wiley & Sons, 2015)
In this study, the feasibility of using fly ash to manufacture high-temperature mortars was investigated. The investigation was set to define preliminary characteristics of new types of mortars based on ordinary and/or ...
