X-ray emission and Mossbauer spectra and electronic structure of ScFe2Si2 and HfFe2S2compounds
(Belgrade : Materials Research Society of Serbia, 2014)
The valence band electronic structure of compounds with the HfFe2S2 crystal lattice type has been established for the first time based on X-ray emission spectroscopy measurements. Band structure and theoretical spectra of ...
The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Directed growth of nanoarchitected hybrid phosphor particles synthesized at low temperature
(Elsevier, 2014)
Sub-micronic particles are of considerable interest for a wide variety of applications, such as catalyst or optical ceramics, due to their unique properties determined by size, composition and structure. In this work, we ...
Photocatalytic activity of ZnO-PEO composites
(Belgrade : Materials Research Society of Serbia, 2014)
The removal of organic pollutants from wastewater is very important for environmental protection. During the years different methods have been developed and applied on wastewater treatment. Between those methods a heterogeneous ...
Electrochemical oxygen reduction at platinum catalyst on tin oxide based support in alkaline solution
(Belgrade : Materials Research Society of Serbia, 2014)
Platinum on Sb doped tin oxide support (Sb/SnO2) was synthesized and characterized as the catalyst for oxygen reduction reaction in 0.1 mol dm-3NaOH solution, at 25oC. Sb (5%) doped tin oxide support was synthesized by ...
Spectroscopic characterization of bone tissue of experimental animals after glucocorticoid treatment and recovery period
(Elsevier, 2014)
The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Korelacija funkcionalnih i fizičko-hemijskih svojstava prahova ZnO dobijenih različitim metodama sinteze
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2014)
Poznato je da funkcionalna svojstva cink oksidnih prahova zavise od fizičko-hemijskih karakteristika kao što su optičke karakteristike i specifična površina, a koje su određene strukturnim svojstvima praha u kao što su: ...
Structural, morphological and up-converting luminescence characteristics of nanocrystalline Y2O3:Yb/Er powders obtained via spray pyrolysis
(Ceramics International, 2014)
Sub-micronic, spherical Y2O3:Yb/Er particles comprising clustered nano-units (70 nm) were prepared via ultrasonic spray pyrolysis from pure nitrate precursor solutions with different Yb/Er dopant ratios. The particles were ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750–1250 °C in air. Structural, morphological and ...
