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 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 ...
Synthesis of Y2SiO5 : Eu3+ nanoparticles from a hydrothermally prepared silica sol
(Journal of Alloys and Compounds, 2008)
In this paper, a novel route for the synthesis of Y2SiO5 (YSO) nanoparticles doped with Eu3+ ions. based on the use of a hydrothermally prepared silica sol as a chemical precursor and nanostructurign template, is presented. ...
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 ...
Comparative reflection and structural analyses of copper and zinc coatings electrodeposited from acid sulfate solutions with and without additives
(Surface and Coatings Technology, 2002)
Reflection and structural analyses of different copper and zinc coatings were performed. The coatings of copper obtained were from acid sulfate solutions in the absence and presence of thiourea. The coatings of zinc were ...
Synthesis and characterization of tungsten carbide fine powders
(Ceramics International, 2015)
Fine tungsten carbide (WC) powder was prepared by solid state reaction between tungsten powder (W) and activated carbon cloth as a new carbon (C) source. The effect of temperature and time of heat treatment as well as the ...
Effect of samarium addition and annealing on the properties of electrodeposited ceria thin films
(Thin Solid Films, 2011)
Samarium (Sm)-doped ceria (CeO2) (SDC) is a promising material for high temperature electrochemical devices. Our work demonstrates that thin SDC films can be prepared by a cost-effective electrodeposition method at a ...
Porous acicular mullite obtained by controlled oxidation of waste molybdenum disilicide
(Materials Research Bulletin, 2014)
Porous acicular mullite was fabricated by using waste MoSi2 heating element and Al2O3. Careful calcination of the pulverized heating element led to the formation of a mixture of MoO3 and amorphous SiO2. This mixture was ...
Rapid crystallization of LiFePO4 particles by facile emulsion-mediated solvothermal synthesis
(Powder Technology, 2012)
Lithium iron phosphate powders were obtained by solvothermal treatments of quaternary emulsions Triton X-100/cyclohexane/n-hexanol/water at low temperature (180 degrees C), with or without stirring. Such synthesis conditions ...
Room temperature ferromagnetism in Cu2+ doped TiO2 nanocrystals: The impact of their size, shape and dopant concentration
(Elsevier, 2016)
Cu2+ doped TiO2 nanocrystals were synthesized using dispersions of titania nanotubes in the presence of Cu2+ ions as a precursors. The morphologies of nanotubular titania precursors and resulted Cu2+ doped TiO2 nanocrystals ...
