Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Sol-gel Synthesis of Anatase Nanopowders for Efficient Photocatalytic Degradation of Herbicide Clomazone in Aqueous Media
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M ...
Characterization of Sedimentary Minerals from Kolubara Mining Basin, Serbia, with the Determination of Natural Radioactivity
(International Institute for the Science of Sintering, 2022)
Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received and treated materials, diatomite and clay ...
Fast Oxide-Ion Conductors in Bi2O3-V2O5 System: Bi108-xVxO162+x(x=4-9) with 3 x 3 x 3 Superstructure
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
In this study, the possibility to stabilize O-2 ion conductors in Bi2O3-V2O5 system was investigated. Six pseudo-binary Bi2O3-V2O5 mixtures [3.50 lt x(V2O5) lt 8.50 mol%] were thermally treated at 1000 degrees C for 1 ...
Study of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Barium-bismuth titanate, BaBi4Ti4O15 (BBT), a member of Aurivillius bismuth-based layer-structure perovskites, was prepared from stoichiometric amounts of barium titanate and bismuth titanate obtained via mechanochemical ...
Far infrared properties of sintered PbTe doped with boron
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fated using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm(-1) and 285 ...
Modification of the structural and optical properties of commercial ZnO powder by mechanical activation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Mechanical activation was used as a method for modification of the structural and optical properties of commercial ZnO powder. For this purpose zinc oxide powder was mechanically treated by grinding in a high-energy ...
TEM and DFT Study of Basal-plane Inversion Boundaries in SnO2-doped ZnO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
In our recent study (Ribie et al. 2020) we reported the structure of inversion boundaries (IBs) in Sb2O3 -doped ZnO. Here, we focus on IBs that form in SnO2-doped ZnO. Using atomic resolution scanning transmission electron ...
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 ...
Study of Dielectric Behavior and Electrical Properties of Hematite alpha-Fe2O3 Doped with Zn
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
