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 ...
A novel reduction-oxidation synthetic route for hafnia
(Elsevier, 2016)
Amorphous hafnia (HfO2) powders were synthesized through a novel reduction oxidation route, in which, metal hafnium was reduced from hafnium tetrachloride (HfCl4) by sodium borohydride (NaBH4), and then oxidized in ambient ...
Structural and magnetic properties of hydrothermally synthesized beta-MnO2 and alpha-KxMnO2 nanorods
(Elsevier, 2016)
Hydrothermal synthesis was applied for obtaining different manganese dioxide polymorphs whose morphology, structure and magnetic properties were thoroughly investigated. Variations in the synthesis pathways lead to the ...
Site preference of Hf dopant in Ni3Al alloys: A perturbed angular correlation study
(Journal of Alloys and Compounds, 2015)
Perturbed angular correlation measurements of the hyperfine interactions of the Ta-181 probe in the polycrystalline intermetallic Ni3Al doped with 0.5 and 5 at.% Hf were performed in the temperature range 78-1230 K. The ...
Identification of phase components in Zr-Ni and Hf-Ni intermetallic compounds; investigations by perturbed angular correlation spectroscopy and first principles calculations
(Journal of Alloys and Compounds, 2017)
Time-differential perturbed angular correlation (TDPAC) measurements have been carried out in stoichiometric ZrNi3 and HfNi3 intermetallic compounds using Ta-181 probe in the temperature range 77-1073 K considering the ...
Insertion of lithium ion in anatase TiO2 nanotube arrays of different morphology
(Journal of Alloys and Compounds, 2017)
Anatase TiO2 nanotube arrays of different morphology were prepared by a two-step process: anodic oxidation at voltages 20-60 V and subsequent annealing at 400 degrees C. By amplifying anodization voltage the inner diameter ...
Structural investigation of mechanically activated nanocrystalline BaTiO3 powders
(Elsevier, 2011)
In this article, in order to obtain tetragonal nanocrystalline BaTiO3, structural investigations of mechanically activated BaTiO3 powder have been performed. A mercury porosimetry analysis and scanning electron microscopy ...
Ouzo effect-New simple nanoemulsion method for synthesis of strontium hydroxyapatite nanospheres
(Elsevier, 2016)
Nanoemulsion technique was applied for synthesis of carbonated strontium hydroxyapatite (CSrHAp) at room temperature. X-ray powder diffraction analysis accompanied with Rietveld refinement reviled that synthesized powder ...
Europium-doped nanocrystalline Y2O3 - La2O3 solid solutions with bixbyite structure
(Journal of Physics and Chemistry of Solids, 2014)
Nanocrystals of Y2O3 and La2O3 solid solutions were synthesized with a cubic bixbyite structure containing La2O3 content of up to 50 mol%. This is comparatively higher than that in bulk materials of the same structure, ...
Xenon implantation effects on the structural and optical properties of reactively sputtered titanium nitride thin films
(Materials Research Bulletin, 2017)
The present study deals with irradiation effects induced by xenon ions (Xe+ on titanium nitride (TiN) thin films. TiN films thickness of 260 urn obtained by using dc reactive sputtering were irradiated with 400 keV Xe ions. ...
