Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Physics and Chemistry of Minerals, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Effects of O2+ ions beam irradiation on crystal structure of rare earth sesquioxides
(Applied Surface Science, 2009)
We report the results of ion irradiation influence on rare earth sesquioxides structure, which are materials of practical importance as a radiation resistant ceramics in nuclear applications. Y2O3, Gd2O3 and Er2O3 sesquioxides ...
Improved efficiency of sol-gel synthesized mesoporous anatase nanopowders in photocatalytic degradation of metoprolol
(Materials Research Bulletin, 2013)
The structural and morphological properties of mesoporous anatase nanopowders, synthesized by sol-gel method, have been modified by varying the duration of calcination, in order to obtain more efficient photocatalyst than ...
Determination of Microstructural Changes By Severely Plastically Deformed Copper-Aluminum Alloy: Optical Study
(Journal of mining and metallurgy, Section B: Metallurgy, 2014)
Our work deals with the problem of producing a complex metal-ceramic composite using the processes of internal oxidation (IO) and severe plastic deformation. For this purpose, Cu-Al alloy with 0.4wt.% of Al was used. IO ...
Gallium doping influence on optical and transport properties of PbTe
(Materials Science Forum, 2000)
Zn this work we used far-infrared and Raman spectroscopy for investigation of gallium doping influence on optical and transport properties of PbTe. We focused our interest to fortify the correlation between local modes and ...
Preparation and characterization of spinel nickel ferrite obtained by the soft mechanochemically assisted synthesis
(Materials Research Bulletin, 2013)
Nickel ferrite, NiFe2O4 has been prepared by a soft mechanochemical route from mixture of (1) Ni(OH)(2) and alpha-Fe2O3 and (2) Ni(OH)(2) and Fe(OH)(3) powders in a planetary ball mill for varying duration. Soft mechanochemical ...
Characterization of partially inverse spinel ZnFe2O4 with high saturation magnetization synthesized via soft mechanochemically assisted route
(Journal of Physics and Chemistry of Solids, 2014)
ZnFe2O4 was prepared by a soft mechanochemical route from two starting combinations of powders: (1) Zn(OH)(2)/alpha-Fe2O3 and (2) Zn(OH)(2)/Fe(OH)(3) mixed in a planetary ball mill. The mechanochemical treatment provoked ...
Comparative study on modification of single wall carbon nanotubes by sodium dodecylbenzene sulfonate and melamine sulfonate superplasticiser
(Applied Surface Science, 2009)
In this work, the results of synthesis and characterization of single wall carbon nanotubes (SWCNTs) functionalized by two surfactants (sodium dodecylbenzene sulfonate and melamine sulfonate superplasticiser) have been ...
Surface chemical modification of fullerene by mechanochemical treatment
