ZnTiO3 ceramic nanopowder microstructure changes during compaction
(Belgrade : International Institute for the Science of Sintering, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterized. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Preparation of MEMO silane-coated SiO2 nanoparticles under high pressure of carbon dioxide and ethanol
(Elsevier, 2010)
The objective of this study is to investigate and compare methods of nanosilica coating with γ-methacryloxypropyltrimethoxy (MEMO) silane using supercritical carbon dioxide and carbon dioxide-ethanol mixture. Characterization ...
Application of magnetite/3D-printed wollastonite hybrid sorbent for As(V) removal from water
(Belgrade : Serbian Ceramic Society, 2019)
The maximal allowed concentration (MAC) for As(V) in water decreased from 50 to 10 μg/l, by considering the harmful effects of arsenic on the environment and human health. In order to achieve the established rigorous ...
Analyzing the corrosion characteristics of anodes used for the sulphur acidic waste water treatment
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. The copper anodes with non-standard ...

Fractal nature Heywang model correction and Brownian motions
(Belgrade : Serbian Ceramic Society, 2017)
Ceramics grains contacts are essential for understanding complex dielectric properties of electronic ceramics materials. Since the actual contact surface is an irregular object, the theory of fractal sets is applied. Also, ...
Comparative fractal analysis of Valeriana officinalis roots shrinkage during drying
(Belgrade : Serbian Ceramic Society, 2016)
Valerian plant roots (Valeriana officinalis)shrinkage was investigated during the convective hot air drying. Combined fractal and image analysis was performed in this study.The samples were prepared for light microscopy ...
Structural and magnetic properties of Y1-xYbxF3 solid solution
(Belgrade : Serbian Ceramic Society, 2018)
In this work, the polycrystalline samples Y1-xYbxF3 (x = 0.01, 0.05, 0.1, 0.25, 0.5, 0.75 and 1) were synthesized and characterized by X-ray powder diffraction and magnetic measurements. In the first stage of synthesis, ...
