  • High-resolution 27Al MAS NMR spectroscopic studies of the response of spinel aluminates to mechanical action 
    Šepelák, Vladimir; Bergmann, Ingo; Indris, Sylvio; Feldhoff, Armin; Hahn, Horst; Becker, Klaus-Dieter; Grey, Clare P.; Heitjans, Paul (Cambridge : Royal Society of Chemistry, 2011)
    The response of the local structure of various types of spinel aluminates, ZnAl2O4 (normal spinel), MgAl2O4 (partly inverse spinel), and Li0.5Al2.5O4 (fully inverse spinel), to mechanical action through high-energy milling ...
  • Nonequilibrium structure of Zn 2SnO 4 spinel nanoparticles 
    Šepelák, Vladimir; Becker, Sebastian M.; Bergmann, Ingo; Indris, Sylvio; Scheuermann, Marco; Feldhoff, Armin; Kübel, Christian; Bruns, Michael; Stürzl, Ninette; Ulrich, Anne S.; Ghafari, Mohammad; Hahn, Horst; Grey, Clare P.; Becker, Klaus-Dieter; Heitjans, Paul (Cambridge : Royal Society of Chemistry, 2012)
    Zinc stannate (Zn 2SnO 4) nanoparticles with an average size of about 26 nm are synthesized via single-step mechanochemical processing of binary oxide precursors (ZnO and SnO 2) at ambient temperature, without the need for ...
  • Strontium doping in mullite-type bismuth aluminate: A vacancy investigation using neutrons, photons and electrons 
    Gesing, Thorsten M.; Schowalter, Marco; Weidenthaler, Claudia; Murshed, M. Mangir; Nénert, Gwilherm; Mendive, Cecilia B.; Curti, Mariano; Rosenauer, Andreas; Buhl, Josef-Christian; Schneider, Hartmut; Fischer, Reinhard X. (Cambridge : Royal Society of Chemistry, 2012)
    We report on strontium doped dibismuth-nonaoxoaluminate(III) produced at 1023 K. Partial substitution of bismuth by strontium in the structure yields oxygen vacancies for charge balance. Introducing oxygen vacancies ...
  • Synthesis of ternary transition metal fluorides Li 3MF 6via a sol-gel route as candidates for cathode materials in lithium-ion batteries 
    Kohl, Julia; Wiedemann, Dennis; Nakhal, Suliman; Bottke, Patrick; Ferro, Noel; Bredow, Thomas; Kemnitz, Erhard; Wilkening, Martin; Heitjans, Paul; Lerch, Martin (Cambridge : Royal Society of Chemistry, 2012)
    A sol-gel route for ternary lithium fluorides of transition metals (M) is presented allowing the synthesis of Li 3MF 6-type and Li 2MF 5-type compounds. It is based on a fluorolytic process using transition metal ...
