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 ...
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. ...
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 ...
Preparation of Nanosized Non-Oxide Powders Using Diatomaceous Earth
(Science of Sintering, 2009)
In this paper the nanosized non-oxide powders were prepared by carbothermal reduction and subsequent nitridation of diatomaceous earth which is a waste product from coal exploitation. Our scope was to investigate the ...
Stereospecific ligands and their complexes. Part XV. Synthesis, characterization and cytotoxicity of novel platinum(IV) complexes with some esters of ethylenediamine-N,N -di-S,S-(2,2 -dibenzyl)acetic acid. Crystal structure of O,O -dipropyl-ethylenediamine-N,N -di-S,S-(2,2 -dibenzyl)acetate dihydrochloride
(Inorganica Chimica Acta, 2013)
The synthesis of ethylenediamine-N,N-di-S,S-(2,2-dibenzyl)acetic acid (H-2-S,S-eddba) and its ethyl-, propyl-, butyl-esters (R-2-S,S-eddba) are reported here. The esters were used for synthesis of the corresponding ...
Structural and magnetic characterization of LiMn1.825Cr0.175O4 spinel obtained by ultrasonic spray pyrolysis
(Materials Research Bulletin, 2007)
Quaternary spinel oxide LiMn1.825Cr0.175O4 Powder was synthesized by using an ultrasonic spray pyrolysis method, without additional annealing. The crystal structure of the as-prepared powder was revealed by X-ray powder ...
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 ...
Modifications of reactively sputtered titanium nitride films by argon and vanadium ion implantation: Microstructural and opto-electric properties
(Thin Solid Films, 2013)
Polycrystalline titaniumnitride (TiN) layers of 240 nmthickness and columnar microstructure were deposited at 150 degrees C by d. c. reactive sputtering on Si(100) wafers and then irradiated at roomtemperature with either ...
Structural and morphological dependences of Sb2S3 nanobars synthesised by organo-colloidal process on precursor concentrations and reaction times
(Journal of Crystal Growth, 2012)
In this paper we report the synthesis of antimony sulphide (Sb2S3) nanobars performed using a simple organo-colloidal synthetic method. The as-synthesised Sb2S3 nanobars with various precursor concentrations and heating ...
