Crystal structure studies on plate/shelf like disodium ditungstate
(Bulletin of Materials Science, 2013)
The structure of plate/shelf like disodium ditungstate (Na2W2O7) synthesized by new method in the process of ultrasonic spray pyrolysis using acidified aqueous solutions of tungsten (VI) oxide clusters as a precursor was ...
Spectroscopy investigation of nanostructured nickel-zinc ferrite obtained by mechanochemical synthesis
(Materials Research Bulletin, 2015)
Nano crystalline samples of nickel zinc ferrite, Ni0.5Zn0.5Fe2O4 were prepared by mechanochemical route in a planetary ball mill starting from two mixtures of the appropriate quantities of the powders: case (1) oxide ...
Structural investigation of mechanically activated nanocrystalline BaTiO3 powders
(Ceramics International, 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 ...
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 ...
Electrostatic Properties of N-Heterocyclic Carbenes Obtained by Experimental Charge-Density Analysis of Two Selenium Adducts
(European Journal of Inorganic Chemistry, 2016)
High-resolution X-ray diffraction data and Hansen-Coppens multipole formalism have been used to obtain the charge density distribution in two selenium adducts with the N-heterocyclic carbenes 1,3-dimesitylimidazolidin-2-ylidene ...
Local structure study of Fe dopants in Ni-deficit Ni3Al alloys
(Journal of Alloys and Compounds, 2015)
The local electronic and magnetic structure, hyperfine interactions, and phase composition of polycrystalline Ni-deficient Ni3-xFexAl (x = 0.18 and 0.36) were investigated by means of Fe-57 Mossbauer spectroscopy. The ...
Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Structural and magnetic properties of hydrothermally synthesized beta-MnO2 and alpha-KxMnO2 nanorods
(Journal of Alloys and Compounds, 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 ...
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 ...
Kinetic study of isothermal crystallization process of Gd2Ti2O7 precursors powder prepared through the Pechini synthetic approach
(Journal of Physics and Chemistry of Solids, 2015)
Crystallization process of Gd2Ti2O7 precursors powder prepared by Pechini-type polymerized complex route has been studied under isothermal experimental conditions in an air atmosphere. It was found that the crystallization ...
