  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

  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.

  6. 4. Ca-Pd/Pt-Ge Compounds on the Zintl Border

    Author : Isa Doverbratt; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Zintl compounds form a category in intermetallic chemistry somewhere between metallic and ionic compounds. Classical Zintl compounds form between electropositive and electronegative elements, such as the alkaline earth metals and the p-block elements, i.e. elements with a relatively large electronegativity difference.
