    The local structure characterization and resulting phase-transition mechanism of amorphous ZrO2

    In the framework of Faber-Ziman's formalism, the radial atomic number density distributions ρ(r) for two amorphous ZrO2-gel samples have been derived, and used to perform local structure simulations based on the ...

    Structural properties of ultra-fine zirconia powders obtained by precipitation methods

    We have investigated various aspects of the stabilization of the tetragonal (t) and cubic (c) forms (metastable at room temperature) with respect to the monoclinic (m) form in ultrafine zirconia powders obtain...

    SAXS investigation on the influence of oil dilution on morphological changes in a SBS block copolymer during the first draw cycle

    Spin-cast films of one pure SBS and two oil-extended SBS samples were observed during first cycle drawing in the synchrotron radiation beam at Hasylab. For evaluation, from a two-dimensional Vidicon scattering...

    Morphological changes in SBS block copolymers caused by oil extension as determined by absolute small angle x-ray scattering

    A series of SBS block copolymers diluted with different amounts (0–60 wt%) of three different kinds of oil were investigated: 1) lithene PM (a low molecular weight polybutadiene); 2) a paraffinic mineral oil w...
