In the past decades, there is a growing interest in the design and synthesis of composite microspheres with a dielectric solid sphere (e.g., silica, polystyrene) covered by metallic and their corresponding metal oxides shell, such as copper[1], gold[2], silver[3,4], iron oxide[5], zinc oxide[6,7], titanium oxide[8,9] and zirconium dioxide[10]. Such materials may exhibit a few unique electrical,...

Iron (Fe) and nitrogen (N) were introduced as dopants into zirconium titanate (ZrTiO4) in order to study the codoping effects of on iron-doped (Fe,N-codoped ZrTiO4) composite. Titanium tetraisopropoxide (TTIP), zirconia (ZrO2), urea, iron(II) sulfate heptahydrate used source TiO2, semiconductor supports, nitrogen, iron, respectively. A specific amount iron (1, 3, 5, 7, 9 wt.%) a fixed content (...

The methods commonly used for precipitating aluminum by 8-hydroxyquinoline from an acetic-acid solution, buffered with ammonium acetate, do not sufficiently define the conditions requisite for complete precipitation. The present article describes a method in which aluminum is precipitated as the oxyquinolate from a solution which has been partially neutralized with ammonium hydroxide, using bro...

During a severe accident in nuclear reactor, the melting of core may lead to formation multiphase liquid pool (corium) vessel lower head. The heat transfer at boundary with is affected by diffusive and convective mass fluxes. In particular, development Rayleigh–Taylor instabilities influence thickness top metallic layer therefore “focusing effect” flux, which main risk for integrity. We use Cah...

Zirconium carbide nanoparticles were produced by wire explosion process by exploding zirconium conductor in methane ambiance. X-ray diffraction studies of the particles produced by wire explosion process confirm the formation of cubic zirconium carbide particles. The results of the study indicates that unreacted zirconium content in the zirconium carbide powder could be reduced by exploding the...

In order to control of the calcium phosphate precipitation of Ti in body fluid, which might result in assimilated bone re-facture during removal operation of implanted devices such as femoral nails and bone screws after healing, vacuum vapor deposition of Zr on Ti Substrate was carried out. The calcium phosphate precipitation was evaluated through the immersion test into the Hanks’ solution. Sc...

Biomass-based adsorbents have been widely studied as a cost-effective and environmentally-benign means to remove pollutants and nutrients from water. A two-stage treatment of aspen wood particles with solutions of carboxymethyl cellulose (CMC) and ferrous chloride afforded a biosorbent that was effective in removing phosphate from test solutions. FTIR spectroscopy of the biosorbent samples show...
