Methods of decreasing losses in optical metamaterials
(Niš, Srbija : Univerzitet u Nišu, 2018)
In this work we review methods to decrease the optical absorption losses in metamaterials. The practical interest for metamaterials is huge, but the possible applications are severely limited by their high inherent optical ...
Study of microstructure and magnetic properties of optimally annealed R/Q Nd4.5Fe77B18.5 alloy
(Metalurgija, 2009)
The rapid-quenched (R/Q) and subsequently optimally annealed Nd-Fe-B alloy with 12 wt% Nd was characterized using the X-Ray diffractometry (XRD), transmission electron microscopy (TEM), high resolution transmission electron ...
Concepts of 3D terrain modeling and geomorphometric analysis in mining
(Institut za rudarstvo i metalurgiju Bor, 2016)
This paper describes the concepts of 3D terrain models and their application in mining. The methods of terrain (relief) by spots elevation and contour lines are commonly applied on geodetic plans and topographic maps. ...
Temperature measurement performance of silicon piezoresistive MEMS pressure sensors for industrial applications
(Univerzitet u Nišu, 2015)
Temperature and pressure are the most common parameters to be measured and monitored not only in industrial processes but in many other fields from vehicles and healthcare to household appliances. Silicon microelectromechanical ...
The first record of the genus Decussata (Patrick) Lange-Bertalot (Bacillariophyta) in Serbia – description, distribution and ecology of the rare species D. hexagona (Torka) Lange-Bertalot
(Institute of Botany and Botanical Garden 'Jevremovac', 2016)
The aim of this paper is to present the distribution of Decussata hexagona, a new species in diatom
flora of Serbia. Seventy-two diatom samples were collected from six localities along the Vrla and
Rasina Rivers during ...
PtAu catalyst with enhanced activity for formic acid oxidation / PtAu katalizator sa poboljšanom aktivnošću za reakciju oksidacije mravlje kiseline
(Belgrade, Serbia : Engineering Society for Corrosion, 2018)
PtAu systems are recognized as good catalysts for the oxidation of formic acid electrooxidation, which is investigated as a possible anodic reaction in low-temperature fuel cells. In this research, bimetallic PtAu ...
Chemical characterization of essential oil from seeds of wild and cultivated carrots from Serbia / Hemijska karakterizacija etarskih ulja semena divlje i gajene mrkve poreklom iz Srbije
(University of Belgrade, 2016)
Seeds from wild carrot (Daucus carota L. ssp. carota) have been used for medicinal purposes since ancient times. Today the oil of its seeds has been proved to possess antinociceptive, antiinflammatory, hypoglycaemic, ...
Bioremediation of soil polluted with oil
(Čačak, Serbia : Univerzitet u Kragujevcu - Agronomski fakultet, Čačak, 2021)
Microplastics have reached all corners of our planet, including soil and water. Plastic-degrading bacteria are seen as a promising, environmentally friendly tool for the bioremediation of soil polluted with microplastics. ...
Solvatochromism of N-aryl-phenylacetamides / Solvatohromizam N-aril-fenilacetamida
(Belgrade, Serbia : Engineering Society for Corrosion, 2016)
Amide derivates are biologically active compounds and they are widely used in all spheres of life. Therefore, it is very important to know their physical-chemical properties. In this work the influence of characteristics ...
Technological investigations of sulphide oxidation from flotation tailings in order to increase the degree of copper leaching
(Institut za rudarstvo i metalurgiju Bor, 2014)
The off-balance resources present the environmental problem and potential resource for copper extraction. This paper presents the results obtained using different reagents for the process of sulphide form oxidation of ...
