Mechanical alloying of an immiscible - Fe 2 O 3 - SnO 2 ceramic

Phase relations , transparency and conductivity in Ga 2 O 3 – SnO 2 – ZnO

Subsolidus phase relationships in the Ga2O3–SnO2–ZnO system were determined at 1250 ◦C using solid state synthesis and X-ray powder diffraction. The two spinels, Zn2SnO4 and ZnGa2O4, formed a complete solid solution. The optical band gap of the spinel varied with composition from 3.6 eV (Zn2SnO4) to 4.7 eV (ZnGa2O4). All samples were white and insulating except those containing Ga-doped ZnO. Th...

Generation of Ag-Ag(2)O complex nanostructures by excimer laser ablation of Ag in water.

Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processi...

Growth mechanisms of SnO(2)/Sn nanocables.

SnO(2)/Sn nanocables have been grown on single-crystal Si substrates by metal catalyst assisted thermal evaporation of SnO powders. The morphologies and structures of the prepared nanocables were determined on the basis of field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), Raman and photoluminescence (PL) spect...

Facile electrochemical characterization of core/shell nanoparticles. Ag core/Ag(2)O shell structures.

We report in this paper a facile approach for the formation and electrochemical characterization of silver-silver oxide core-shell nanoparticles (NPs). Thus, thermal treatment at temperatures between 200 and 360 degrees C of Ag NP, in the gas phase or in an organic solvent, has been used to achieve the formation Ag@Ag2O NP. The evidence of formation of such a core-shell structure was obtained b...
