  2. 1. Investigating Hydrogenous Behavior of Zintl Phases : Interstitial Hydrides, Polyanionic Hydrides, Complex Hydrides, Oxidative Decomposition

    Author : Verina Kranak; Ulrich Häussermann; Gordon Miller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zintl phases; Hydrogenous Zintl phases; Polyanionic Zintl phases; Interstitial Zintl phases; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is an investigation into the hydrogenous behavior of Zintl phases. Zintl phases are comprised of an active metal (i.e alkali, alkaline earth, and rare earth) and a p-block element. The discussion gives an overview of the influence hydrogen affects the electronic and geometric structure of Zintl phases and subsequent properties. READ MORE

  4. 2. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Author : Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Abstract : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. READ MORE

  5. 3. Hydrogen incorporation in Zintl phases and transition metal oxides- new environments for the lightest element in solid state chemistry

    Author : Reji Nedum Kandathil; Ulrich Häussermann; Michael A. Hayward; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zintl phases; metal hydrides; transition metal oxyhydrides; XRPD; NPD; Rietveld refinement; Materials Chemistry; materialkemi;

    Abstract : This PhD thesis presents investigations of hydrogen incorporation in Zintl phases and transition metal oxides. Hydrogenous Zintl phases can serve as important model systems for fundamental studies of hydrogen-metal interactions, while at the same time hydrogen-induced chemical structure and physical property changes provide exciting prospects for materials science.
