Quantifying shapes of nanoparticles using modified circularity and ellipticity measures
(Measurement, 2016)
We propose using a new circularity measure, and an ellipticity measure. Observing an example of hematite (alpha-Fe2O3) nanoparticles, we compared and discussed a new circularity measure, with a standard measure. It has ...
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Belgrade : Serbian Chemical Society, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt’s baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Springer Verlag, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Integrity assessment of regulation system pipeline elements in hydroelectric generating set a6 of hydro power plant 'Djerdap 1'
(Society for Structural Integrity and Life, Institute for Material Testing, 2016)
Vertical Kaplan turbines with nominal power of 176 MW manufactured in Russia are installed in 6 hydroelectric generating sets at hydro power plant 'Djerdap 1' (Kladovo, Serbia). Most of the components are made of materials ...
Analysis of metal ion release from biomedical implants
(Association of Metallurgical Engineers of Serbia, 2013)
Metallic biomaterials are commonly used for fixation or replacement of damaged bones in the human body due to their good combination of mechanical properties. The disadvantage of metals as implant materials is their ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solution. Chemical composition, phase composition and morphology effects
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
Mechanical properties and microstructure of the ZrO25CaO/NiCrAl coating system / Mehaničke osobine i mikrostruktura sistema prevlaka ZrO25CaO/NiCrAl
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
ZrO25CaO is a versatile class of material that can be sintered or plasma spray deposited in combination with other materials on the implant substrate. Due to brittleness the organic ceramic hydroxyapatite Ca10(PO4)6(OH)2 ...
Selection of lactic acid bacteria strain for simultaneous production of α- and β-galactosidases / Izbor mlečnokiselinske bakterije za istovremenu proizvodnju α- i β-galaktozidaza
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Galactosidases are group of enzymes gaining increasing attention in recent times due to the fact they catalyse hydrolysis of galatose-containing oligosaccharide, which reduce digestibility of various food and feed products. ...
