1. 1. Terminating species and Lewis acid-base preference in oxohalides – a new route to low-dimensional compounds

   Författare :Richard Becker; Mats Johnsson; Jean Galy; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Low dimensionality; crystal structures; tellurites; selenites; oxohalides; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : This thesis is based upon synthesis and structure determination of new transition metal oxo-halide compounds, which includes p-element cations that have a stereochemically active lone pair. A synthesis concept has been developed, which uses several different structural features to increase the possibility to yield a low-dimensional arrangement of transition metal cations. LÄS MER

   Sammanfattning : Rechargeable batteries have already conquered the market of portable electronics (i.e., mobile phones and laptops) and are set to further enable the large-scale deployment of electric vehicles and hybrid electric vehicles in a not too distant future. LÄS MER

4. 3. The Role of Tetrahedral Building Blocks in Low-Dimensional Oxohalide Materials

   Författare :Iwan Zimmermann; Mats Johnsson; Lars Kloo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lone-pair elements; crystal structure; low-dimensional compounds; oxohalides; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : The structural architecture found in low-dimensional materials can lead to a number of interesting physical properties including anisotropic conductivity, magnetic frustration and non-linear optical properties. There is no standard synthesis concept described thus far to apply when searching for new low-dimensional compounds, and therefore control on the design of the new materials is of great importance.
