Magneto-dielectric properties of ferrites and ferrite/ferroelectric multiferroic composites
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2019)
Ni-Zn ferrites, with the general formula Ni1-xZnx Fe2O4 (x = 0.0, 0.3, 0.5, 0.7, 1.0), CoFe2O4, BaTiO3 and PbZr0.52Ti0.48O3 powders were synthesized by auto-combustion method. The composites were prepared by mixing the ...
Low-temperature photoluminescence of CuSe2 nano-objects in selenium thin films
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
Thin films of CuSe2 nanoparticles embedded in selenium matrix were prepared by vacuum evaporation method on a glass substrate at room temperature. The optical properties of the films were investigated by photoluminescence ...
Influence of starting powder milling on magnetic properties of Mn-Zn ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
In this paper, the influence of additional sieving and milling of starting industrial Mn-Zn powders on magnetic properties was investigated. The starting powder was milled for 60 minutes, followed by sieving through 325 ...
Enhanced photocatalytic degradation of RO16 dye using Ag modified ZnO nanopowders prepared by the solvothermal method
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
In this work, Zn(CH3 COO)(2) 2 H-2 O with AgNO3 content from 0 to 6 mol% was solvothermally treated at 120 C for 18 h in the presence of poly(vinyl pyrrolidone), ethylene glycol and sodium hydroxide. The structural , ...
Organic crystals – More than simple additives toward better electroceramic materials
(Faculty of Technology, University of Novi Sad, 2010)
Roles of various organic crystals (OC), notably those containing nitrogen, on the preparation and properties
of source materials for electroceramics are featured from the author’s own experimental studies. When OC ...
Fabrication of ZrC/SiC, ZrO2/SiC and ZrO2 powders by carbothermal reduction of ZrSiO4
(Processing and Application of Ceramics, 2011)
The zirconia/silicon carbide (ZrO2 /SiC) and ZrO2 powders are prepared by carbothermal reduction of natural mineral zircon (ZrSiO4). The zircon powder was mixed with activated carbon as a reducing agent and heat treated ...
Aurivillius BaBi4Ti4O15 based compounds: Structure, synthesis and properties
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2013)
The discovery of some Aurivillius materials with high Curie temperature or fatigue-free character suggests possible applications in high temperature piezoelectric devices or non-volatile ferroelectric random access memories. ...
Dielectric investigations of La-doped barium titanate
(Faculty of Technology, University of Novi Sad, 2010)
In the present paper results of the dielectric investigation of barium titanate (BaTiO3) doped with different
concentrations of lanthanum are presented. Ceramic samples were prepared by the Pechini process. With ...
TEM and FESEM investigation of lanthanum nickelate thin films obtained by chemical solution deposition
(University of Novi Sad, 2012)
Lanthanum nickelate (LNO) is a perovskite oxide material with metallic conductivity in a wide temperature
range which makes it suitable for application as electrode material for thin films. In this paper LNO thin films
were ...
Barium titanate thick films prepared by screen printing technique
(Faculty of Technology, University of Novi Sad, 2010)
The barium titanate (BaTiO3) thick films were prepared by screen printing technique using powders obtained
by soft chemical route, modified Pechini process. Three different barium titanate powders were prepared: i)
pure, ...
