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 ...
Structural and functional properties of ZnO thin films grown on Si substrates by air assisted USP method from non-aqueous solutions at low-temperature
(Advanced Powder Technology, 2017)
In this work, we deals with the processing and characterization of transparent conducting ZnO thin films on p-type Silicon substrates (1 0 0) by air assisted Ultrasonic Spray Pyrolysis (USP) method. The thin films from ...
Preparation of pozzolanic addition by mechanical treatment of kaolin clay
(Elsevier, 2014)
Batches containing 5 kg of Serbian medium-quality kaolin clay were mechanically treated in a conventional ball mill for 10, 30, 60, 120, 600 and 1200 min of milling time. High reactive pozzolanic addition was obtained as ...
Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(Elsevier, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
New multifunctional materials based on steel slag
(Belgrade : Materials Research Society of Serbia, 2018)
Electric arc furnace slag (EAFS) is the by-product of steel production in an electric arc furnace. In a pass two decade a special attention is paid to the valorization of metallurgical slags by alkali activation. The process ...
Highly sensitive graphene-based chemical and biological sensors with selectivity achievable through low-frequency noise measurement — Theoretical considerations
(IEEE, 2014)
We have developed a theory of the low-frequency noise caused by interaction of the analyte with the active area of chemical and biological sensors. The main result is an analytical expression for the spectral density of ...
