Assessing electrical properties of ceramic samples
(Belgrade : Serbian Ceramic Society, 2017)
We present an overview of electromagnetic numerical techniques and measurement apparatus that have been used for assessing electrical properties of ceramic samples. The complex permittivity of the ceramics is typically the ...
Fractal Simulator and Ceramics Technology for New Tesla’s Fountain
(Belgrade : Serbian Ceramic Society, 2017)
In this study, we present new Tesla’s Fountain model in ceramics technology. It is reconstructed from basic 3D model. The model is designed based on Tesla’s original US patent no. 1,113,716, granted on October, 13 (1914). ...
Synthesis of hierarchically structured Y2O3:Eu3*@ Ag nanocomposites with plasmon enhanced luminesencence via ultrasonic spray pyrolysis
(Belgrade : Serbian Ceramic Society, 2017)
Y2O3:Eu3+@Ag nanocomposites have been successfully synthesized by ultrasonic spray pyrolysis (USP) and examined to reveal effects of surface plasmon resonance, associated to silver nanoparticles, to the luminescence ...
Synthesis of BaFe12O19-BaTiO3 multiferroics by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
A mixture of polycrystalline powders of Fe (70 % wt.) and BaTiO3 (30 % wt.) was ball-milled in a planetary mill under air atmosphere, for different time intervals: 60, 120, 180, 240, 300 and 360 min. During the mechanical ...
Facile synthesis of hydrophilic polymer-capped upconverting NaYF4:Yb,Er particles
(Belgrade : Serbian Ceramic Society, 2017)
Over the last decade, solvothermal decomposition of organometallic compounds has been indicated as one of the most convenient method for the synthesis of monodisperse lanthanide doped upconverting fluorides. Due to their ...
In-vitro visualization of primary tumor cells using up-conversion nanophosphors
(Belgrade : Serbian Ceramic Society, 2017)
For such purpose, Ln-UCNPs should have specific morphological characteristics and efficient luminescence response. In this work, a biocompatible and water dispersible NaYF4:Yb,Er@PLGA nanoparticles synthesized using a ...
Zinc oxide-based materials with enhanced sunlight-driven photo- and photo-electro-catalytic activity
(Belgrade : Serbian Ceramic Society, 2017)
Current trend in photocatalysis is to develop efficient semiconductors which can be activated by absorbing sunlight. Which wavelength of sunlight will be absorbed depends on the semiconductor band gap; semiconductors with ...
Electrical properties of doped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2017)
The electrical resistivity and PTCR (Positive Temperature Coefficient of Resistivity) effect doped BaTiO3 ceramics with different dopant were investigated in this paper, The content of additive in doped samples were ranged ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
