One-step synthesis of NIR-responsive NaYF4:Yb,Er@Chitosane nanoparticles for biomedical application
(Belgrade : Institute of Physics Belgrade, 2017)
There is a great technological interest in synthesis of lanthanide doped upconverting nanoparticles with specific morphological characteristics and efficient luminescence response suitable for biomedical use [1]. A ...
Enhanced natural sunlight- and artificial UV-driven photocatalytic activity of mechanically activated ZnO/SnO2 composite
(Belgrade : Materials Research Society of Serbia, 2017)
Over the past four decades there is an increasing interest to develop highly efficient semiconductor photocatalysts for degradation of organic and biological pollutants in water under light irradiation. The semiconductor ...
Fractals and ceramics materials characterization
(Belgrade : Serbian Ceramic Society, 2017)
Large part of powder based materials; especially ceramics are porous in more or less percentage. For such materials, two separated spaces are present. The “positive” space is made by grains or particles, while the “negative” ...
Influence of synthesis parameters and thermal treatment on functional properties of Fe3O4-BaTiO3 multiferroics obtained by mechanical activation
(Belgrade : Serbian Ceramic Society, 2017)
Mechanical activation of a mixture of polycrystalline powders Fe3O4 (50% wt.) and BaTiO3 (50% wt.) was performed in a planetary ball-mill, with different milling times (3 h, 6 h and 12 h). Average crystallite size determined ...
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). ...
Surface chemistry, thermal stability and structural properties of graphene oxide/12-tungstophosphoric acid nanocomposite
(Belgrade : Institute of Technical Sciences of SASA, 2017)
In recent years the nanocomposites of graphene oxide (GO) and different inorganic and organic compounds have shown great potential for charge storage applications. In present work we have investigated the influence of ...
Is WO3 catalyst for hydrogen desorption?
(Belgrade : Institute of Technical Sciences of SASA, 2017)
Magnesium hydride, as hydrogen storage material, meets the requirements such as high gravimetric hydrogen capacity (7,6 wt%), low cost and weight, abundance and H2 absorption/desorption cycling possibility. Given that the ...
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 ...
