    Structural Elements in Borovanadate Glasses

    The structure of glasses in the Li2O–B2O3–V2O5and ZnO–B2O3–V2O5systems of a high modifier content ([Li2O, ZnO]/[B2O3] ratio > 1) and 10 to 50 mol % V2O5are investigated by V-KEXAFS and Raman spectroscopy. In the ...

    Structural characterization of thin films formed or changed on materials by micro Raman spectroscopy

    Micro Raman spectroscopy is shown as a useful method of high spatial resolution in characterization of thin films on or in materials formed or changed as a result of external influences. Identification of bla...

    The thermal behavior of triethylenediammonium salts

    (trienH2)[CoCl4], which contains tetrahedral chlorocobaltate(II) anions, decomposes under argon in two stages via a stepwise deprotonation of the cation. The decomposition starts at 310°C with the liberation of H...
