Effects of strontium doping on microstructure and functional properties of solution-derived potassium sodium niobate thin films
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2020)
The effects of strontium doping (0-2 mol%) on structure, microstructure and functional properties of potassium sodium niobate (KNN) thin films deposited on Pt(111)/TiOy/SiO2/Si substrates were investigated. Incorporation ...
Nanostructured Fe2O3/TiO2 thick films prepared by screen printing
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2013)
Nanostructured single layered (pure TiO2, pure alpha-Fe2O3 and mixed Fe2O3/TiO2 with two different oxide ratios, 2 : 3 and 3 : 2) and double layered (TiO2 layer over a Fe2O3 layer) thick films have been fabricated by screen ...
Spark plasma sintering of hydrothermally synthesized bismuth ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2016)
Bismuth ferrite, BiFeO3 (BFO), powder was synthesized by hydrothermal method from Bi(NO3)(3)center dot 5H(2)O and Fe(NO3)(3)center dot 9H(2)O as precursors. The synthesized powder was further sintered using spark plasma ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Microstructural, Thermoelectric and Mechanical Properties of Cu Substituted NaCo2O4
(MDPI, 2022)
Polycrystalline samples of NaCo2−xCuxO4 (x = 0, 0.01, 0.03, 0.05) were obtained from powder precursors synthesized by a mechanochemically assisted solid-state reaction method (MASSR) and a citric acid complex method (CAC). ...
Comparison of two alkali-activated systems: mechanically activated fly ash and fly ash-blast furnace slag blends
(Elsevier Science Bv, Amsterdam, 2015)
Poor reactivity of fly ash (FA) in alkali activation process can be improved either by mechanical activation of fly ash or by blending fly ash with more reactive material, such as blast furnace slag (BFS). Both options ...
Processing-Dependent Dielectric and Ferroelectric Properties of BST Ceramics
(Vilnius University, Vilnius, Lithuania, 2014)
Barium strontium titanate, BaxSr1-xTiO3 (BST) ceramics have been extensively used as in a microelectronics due
to its excellent ferroelectric, dielectric, piezoelectric, and pyroelectric properties [1–3]. At room ...
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 ...
Influence of MN doping on the evolution of microstructure and optical properties of mechanically activated SrTiO3 powders
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Manganese doped SrTiO3 powders with various manganese dioxide weight percentages in the range of 1.5, 3 and 6 wp% were prepared by a solid-state method in the presence of mechanical activation (10, 30 and 120 minutes). A ...
