Over the past decade, one-dimensional inorganic nanostructures have emerged as promising materials for fundamental studies and possible technological applications. These structures exhibit physical and chemical properties distinct from their bulk counterparts as a result of radial confinement, while they retain the advantages of wire-like connectivity. In particular, silicon 5] and silicide nan...

The aim of this work is to optimize the oxidation resistance of ZrB2-SiC-based composites with different additives. Effect of nine factors including SiC, Cf, MoSi2, HfB2 and ZrC contents, milling time of Cf (M.t) and SPS parameters such as temperature, time and pressure on oxidation resistance in four levels was investigated. Taguchi design was applied to explore effective parameters for ...

Silicon is produced in submerged arc furnaces which are heated by electric currents passing through the furnace. It important to understand distribution of heating within furnace order accurately model silicon production process, yet many existing studies neglect aspects this current flow. In present paper, we formulate a that couples electrical thermal, material flow and chemical processes We ...

indium tin oxide (ito) thin films were deposited on glass substrates by rf sputtering using an ito ceramic target (in2o3-sno2, 90-10 wt. %). after deposition, samples were annealed at different temperatures in vacuum furnace. the post vacuum annealing effects on the structural, optical and electrical properties of ito films were investigated. polycrystalline ito films have been analyzed in wide...
