Synthesis of zirconia colloidal dispersions by forced hydrolysis
(Journal of the Serbian Chemical Society, 2006)
Different zirconia colloidal dispersions (sols) were prepared from zirconyl oxynitrate and zirconyl oxychloride solutions by forced hydrolysis. Vigorously stirred acidic solutions of these salts were refluxed at 102 degrees ...
Laser reflection spot as a pattern in a diamond coating - a microscopic study
(Journal of the Serbian Chemical Society, 2009)
Diamond coatings were deposited by the synchronous and coupled action of a hot filament CVD method and a pulsed CO(2) laser in spectro-absorbing and spectro-non-absorbing diamond precursor atmospheres. The obtained coatings ...
Influence of carbon concentration and rotational temperature on fullerene yield in RF reactor
(Materials Science Forum, 2006)
In this paper, report on fullerene formation in a radio-frequency (RF) thermal plasma reactor has been presented. In order to determine the degree of evaporation of the graphite precursor used, analysis of SEM micrographs ...
Electrophoretic Deposition of Biocomposite Lignin/Hydroxyapatite Coatings on Titanium
(International Journal of Chemical Reactor Engineering, 2009)
In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified ...
Synthesis of sillenite-type compounds from zeolite precursors: XRPD and SEM/EDS analyses
(Journal of Optoelectronics and Advanced Materials, 2008)
The paper analyze the possibility of using LTA zeolite as a precursor for obtaining sillenite phase (Bi(12)MO(20), M=Si, Ti, Ge) by hydrothermal synthesis process. The synthesis procedure involves mixing of zeolite (Na-LTA) ...
Surface structures formed on AISI 420 stainless steel by pulsed laser irradiation
(Materials Science Forum, 2005)
The effects of TEA CO2 laser radiation on AISI 420 stainless steel and formed surface structures are studied. The laser energy density of 45.0 J/cm(2) has modified the target surface. Qualitatively, the modifications of ...
Nano-second surface modification of titanium nitride thin film by Nd : YAG and TEA CO2 lasers
(Materials Science Forum, 2006)
In this work we investigated the interaction of ns laser pulses (TEA CO2 and Nd:YAG) with a titanium nitride (TiN) thin film. The TiN thin film of 1 mu m thickness was deposited by PVD method on silicon substrate. Modification ...
Hydrogen storage properties of MgH(2)-diatomite composites obtained by high-energy ball milling
(Journal of Microscopy, Oxford, 2008)
To investigate the effects of specific porous microstructure of diatomite on the hydrogen storage properties of MgH(2), a two-step preparation was carried out. The first step was decrepitation of MgH(2) particle size during ...
Hydrogels based on 2-hydroxyethyl methacrylate obtained by gamma irradiation
(Materials Science Forum, 2005)
Hydrogels based on 2-hydroxyethyl methacrylate and different types of poly(alkylene glycol) acrylates and methacrylates, with a small percent of itaconic acid, have been prepared by solution copolymerization using gamma ...
Desorption behaviour in nanostructured MgH2-CO
(Materials Science Forum, 2006)
The influence of the Co addition and synthesis route on desorption properties of MgH2 were investigated. Ball milling of MgH2-Co blends was performed under Ar using different milling intensities and different weight ratios. ...
