    Submarine Mass Movements Along a Sediment Starved Margin: The Menorca Channel (Balearic Islands – Western Mediterranean)

    Sediment starved passive margins, particularly those of insular slopes, display significant mass transport activity despite the absence of environmental stresses from high sedimentation rates. The “Menorca Cha...

    B and P Glass Formers as Stabilizers of Luminescent Ce(III) in Silica-Based Glasses

    Ce3+-doped boro, phospho and borophosphosilicate monolithic glasses (BSG, PSG and BPSG) were prepared by sol-gel method. The inclusion of the glass formers P and B in silica lowered the tendency of rare earth (RE...

    Structure and Size of Poly-Domain Pd Nanoparticles Supported on Silica

    A polydomain internal structure was evidenced by means of High Resolution Transmission Electron Microscopy (HRTEM) in palladium nanoparticles of two 5% Pd/SiO2 catalysts prepared by impregnation technique. Such p...

    Pd-SiO2 catalysts. stability of β-PdHx as a function of Pd dispersion

    Measurements of β-PdHx stoichiometry by hydrogen TPD and of Pd dispersion by CO chemisorption has shown that in Pd−SiO2 catalysts the formation of β-PdHx is more and more hindered with the increase of Pd dispersi...

    Structural investigation on the stoichiometry of β-PdHx in Pd/SiO2 catalysts as a function of metal dispersion

    Structural investigations of dispersed Pd/SiO2 catalysts were carried out with XRD and SAXS techniques, supported by TPR and CO chemisorption measurements. The stoichiometry of Pd hydride, β-PdHx, was determined ...

    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 ...

    Short-term respiratory changes in polyurethane foam workers exposed to low MDI concentration

    Our study included 27 polyurethane foam workers exposed to MDI only at low concentrations (ranging from 0.0005 to 0.001 ppm) and 27 clerks from the same factory matched by age. Respiratory function tests were ...

    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...
