Nanocrystalline SnO2-Zn2SnO4 composite thick films applied as humidity sensors
(Belgrade : Institute for Multidisciplinary Research, 2019)
Starting ZnO and SnO2 nanopowders (<100 nm) were mixed in a suitable ratio and calcined at 1050 °C for 2 hours to obtain nanocrystalline SnO2-Zn2SnO4 composite powder. Structural characterization performed by X-ray diffraction ...
FLUORESCENCE SPECTROSCOPY AND PRINCIPAL COMPONENT ANALYSIS IN THE HONEY SAMPLES CLASSIFICATION
(University of Belgrade, Technical Faculty in Bor, 2019)
Steady state fluorescence spectroscopy in combination with Principal Component Analysis (PCA) for
spectral analysis was used to differentiate multifloral honeys from different parts of Serbia. The
emission spectra were ...
Sinteza, struktura, karakterizacija i fotoelektrohemijska primena debelih slojeva pseudobrukita, Fe2TiO5
(Универзитет у Београду, Технолошко-металуршки факултет, 2019)
U poređenju sa fotonaponskim ćelijama, fotoelektrohemijske ćelije predstavljajuefikasan vid pretvaranja sunčeve energije u električnu, jer se pored energije dobija ivodonik koji se može iskoristiti kao gorivo. Fotoelektrohemijske ...
Structure, morphology and photocatalytic properties of CoxMg1-xFe2O4 (0<x<1) spinel ferrites obtained by sol-gel synthesis
(Belgrade : Materials Research Society of Serbia, 2019)
Nanocrystalline cobalt magnesium ferrites with varying cobalt and magnesium content (CoxMg1-xFe2O4, 0<x<1) were synthesized using the sol-gel self-combustion method with citric acid as fuel, followed by calcination at 700 ...
The effect of pH on visible-light photocatalytic properties of pseudobrookite nanoparticles
(Belgrade : Materials Research Society of Serbia, 2019)
In this study, pseudobrookite (Fe2TiO5) nanoparticles were fabricated by a modified sol-gel method using Fe(NO3)39H2O and Ti(OC3H7)4 as starting reagents and ethanol as solvent. Oxalic acid was used as a chelating agent ...
Structural, optical and photocatalytic properties of BiFeO3 nanoparticles
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2019)
BiFeO3 (BFO) precursor powder was synthesized by ultrasound asissted sol–gel route at relatively low temperature, starting from Bi-nitrate, Fe-nitrate, and ethylene glycol. Structural, optical, and photocatalytic properties ...
Effects of Ag+ Ion Doping on UV Radiation Absorption and Luminescence Profiles of Fluorapatite Nanomaterials Obtained by Neutralization Method
(Polish Acad Sciences Inst Physics, Warsaw, 2019)
In the present study we have analyzed effects of Ag+ ions doping on energetic profiles of nanophosphors materials based on fluorapatite crystal system. The UV radiation absorption and luminescence properties of monophase ...
Imaging FTIR microscopy – technique for rapid screening of plant cell walls
(University of Belgrade, Institute for Biological Research “Siniša Stanković”, National Institute of Republic of SerbiaSerbian Society for Microscopy, Serbia, 2019)
It has been shown that xylan is oriented in parallel to the cellulose and more or less parallel to the
axis of a cell wall, in isolated CW fragments from maize leaves. There was also a clear indication of
lignin orientation ...
Erythrocyte morphometry in pontic shad (Alosa immaculata).
(GEOMORPHOLOGIA SLOVACA ET BOHEMICA, 2019)
Pontic shad (Alosa immaculata) is a migratory fish species, which undergoes long migrations along the Danube River, from Black Sea to the first obstacle that stops the migration the Iron Gate II dam.
Individuals used in ...
