(Prirodno-matematički fakultet, UNS, 2022)
Velika, Zapadna, Južna Morava, kao i Sava, Kolubara i Barička reka su pod značajnim uticajem komunalnih i industrijskih otpadnih voda. Ciljevi studije su procena genotoksičnog potencijala analiziranih lokaliteta i ispitivanje ...
Structural and Electronic Properties of Pseudobrookite
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Starting powders of TiO2 (anatase) and Fe2O3 (hematite) were mixed in the molar ratio 1:1. Pseudobrookite powder was obtained by a combined milling/calcination procedure. Particle size distribution was analyzed on a laser ...
Relation between sputtering parameters and optical and electrical properties of Ga doped ITO transparent conductive oxide
(Elsevier Science Bv, Amsterdam, 2015)
A ceramic target with Ga:In:Sn=4:64:32 metal ratio has been sintered and used for RF sputtering process to develop high quality Ga doped ITO (GITO) transparent conductive oxide layers, particularly for photovoltaic ...
Polyvinyl alcohol PVA with poly ethylene Glycol PEG added as a binder for the powder compaction
(Belgrade : Serbian Ceramic Society, 2018)
During the compaction of the powder mixture of ZnO and Mn2O3 (MnCO3) and Fe2O3 compacts were find fragile for further handling. Poly vinyl alcohol PVA was used as a binder in an unusual 20% PVA content. We made as well 2% ...
