Formation of porous wollastonite-based ceramics after sintering with yeast as the pore-forming agent
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, synthesis of porous wollastonite-based ceramics was reported. Ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as starting material. After 20 min of ultrasound treatment, ...
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 ...
Encapsulation of resveratrol in spherical particles of food grade hydrogels
(Novi Sad : University of Novi Sad - Scientific Institute of Food Technology, 2017)
The paper reports about the preparation and characterization of hydrogel particles containing liposomes loaded with resveratrol as an active compound. The materials used for preparation of the particles were chosen to be ...
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). ...
Sintering of fly ash based composites with zeolite and bentonite addition for application in construction materials
(International Institute for the Science of Sintering, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
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 ...
Electrical properties of magnesium titanate ceramics post-sintered by hot isostatic pressing
(Belgrade : International Institute for the Science of Sintering, 2017)
Post-sintering of magnesium titanate ceramics by hot isostatic pressing (HIP) in an oxygen-free atmosphere significantly alters various electrical properties of the product. In particular, the sintered material becomes a ...
