---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Effect of TiO2 and ZrO2 filler on mechanical properties of the epoxy polymer has been investigated experimentally. TiO2 and ZrO2 filler epoxy composites are fabricated by hand layup technique in a mold and cured under light pressure at room tempera...

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

New solid polymer electrolytes (SPE) based on poly(ethylene oxide) (PEO) doped with lithium trifluoromethanesulfonate (LiCF3SO3), dibutyl phthalate (DBP) plasticizer, and zirconium oxide (ZrO2) nanoparticles were prepared by solution-casting technique. The conductivity was enhanced by addition of dibutyl phthalate (DBP) plasticizer and ZrO2 nanofiller with maximum conductivity (1.38 × 10(-4) Sc...

Thin solid films consisting of ZrO2 and Fe2O3 were grown by atomic layer deposition (ALD) at 400 °C. Metastable phases of ZrO2 were stabilized by Fe2O3 doping. The number of alternating ZrO2 and Fe2O3 deposition cycles were varied in order to achieve films with different cation ratios. The influence of annealing on the composition and structure of the thin films was investigated. Additionally, ...

The band alignment of ZrO2/interfacial layer/Si structure fabricated by simultaneous oxidation and nitridation of sputtered Zr on Si in N2O at 700°C for different durations has been established by using X-ray photoelectron spectroscopy. Valence band offset of ZrO2/Si was found to be 4.75 eV, while the highest corresponding conduction offset of ZrO2/interfacial layer was found to be 3.40 eV; owi...

New MoO3 or WO3 modified CeO2-ZrO2 aerogel catalysts were elaborated using the sol gel method combined to supercritical drying for NO-SCR by NH3 in excess of O2. XRD, N2-Physisorption, NH3-TPD, H2-TPR and DRUV-Vis spectroscopy used analyse samples. The results reveal that all powders (ZrO2, CeO2-ZrO2, MoO3-ZrO2, WO3-ZrO2, MoO3-CeO2-ZrO2 WO3-CeO2-ZrO2), calcined at 500 °C, are nanostructured mes...

Large-scale characterization of phosphoproteins requires highly specific methods for the purification of phosphopeptides because of the low abundance of phosphoproteins and substoichiometry of phosphorylation. A phosphopeptide enrichment method using ZrO2 nanoparticles is presented. The high specificity of this approach was demonstrated by the isolation of phosphopeptides from the digests of mo...
