We have prepared multiwalled carbon nanotube (MWCNT)/In2O3 composites using a simple impregnation method. The precursor compound indium(III) chloride (InCl3) was used to cover the surface of MWCNTs and distilled water was used as solvent. The applied mass ...
Using a combination of single-crystal and powder X-ray diffraction measurements, we study temperature- and pressure-driven structural distortions in zinc(II) cyanide (Zn(CN)(2)) and cadmium(II) imidazolate (Cd(im)(2)), two molecular frameworks with the ant ...
Hintergrund der Machbarkeitsstudie. Mit einem Stollen zwischen Gattikon und dem Zürichsee (Höhe Thalwil) sollen schadenverursachende Hochwasser im Stadtzentrum von Zürich (Hauptbahnhof), sowie in Adliswil und Langnau künftig reduziert und/oder vermieden we ...
We have recently developed a colloidal route to vanadium sesquioxide (V2O3) nanocrystals with a metastable bixbyite crystal structure. In addn. to being one of the first reported observations of the bixbyite phase in V2O3, it is also one of the first succe ...
Seven alloys of the ternary Au-Cu-Pt system, containing 75 or 76.5 wt.% Au with 0-15 wt.% Pt and heat-treated to a fully ordered condition, are examined using in-situ synchrotron radiation to determine transformation temperatures and phases formed, and to ...
Phase-pure tantalum oxynitride (beta-TaON) powders were synthesized by thermal ammonolysis of Ta2O5 powders. X-ray diffraction revealed an enlargement of the unit cell and an increase of the crystallite size with increasing ammonolysis temperature. Scannin ...
Infrared reflection and transmission as a function of temperature have been measured on single crystals of Cu3Bi(SeO3)(2)O2Cl. The complex dielectric function and optical properties along all three principal axes of the orthorhombic cell were obtained via ...
Optimized synthesis of Ti-precursor 'titanylnitrate' for one step combustion synthesis of N- and C-doped TiO2 catalysts were reported and characterized by using powder X-ray diffraction (XRD), transmission electron microscopy (TEM), diffused reflectance UV ...
Texture characterization in thin films from standard powder x-ray diffraction (XRD) rely on the comparison between observed peak relative intensities with those of powder diffraction standards of the same compound, trough the so-called texture coefficient ...
Two series of oxide precursors for perovskite-type (La,Ca)Ti(O,N)(3) were prepared by adding Ca2+ to A-site deficient LaTiO3.5 heterogeneously (Ca2+-backfilling) or by substituting Ca2+ for La3+ in stoichiometric LaTiO3.5 homogeneously (Ca2+-substitution). ...
