1. 1. Non-Standard Crystallography : Examples in 3- and 3+1 Dimensional Space

   Författare :Jeppe Christensen; Sven Lidin; An-Pang Tsai; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modulation; Crystallography; intermetallic; materials; Chemistry; Kemi; strukturkemi; Structural Chemistry;

   Sammanfattning : Crystallography today is by many seen as merely a tool for determining the structure of a material on the atomic level. It is expected that whatever comes out of the tool is the indisputable truth, a fact. This thesis is based on five publications illustrating that this is very far from the real world of materials research. LÄS MER

3. 2. Solide Molydbenum(II) Chloride Cluster compounds From a Hudrogen Bonding Poin of View

   Författare :Andreas Flemström; Sven Lidin; Åke Oskarsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molybdenum Cluster Hydrogen network; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : This thesis is based on a study of solid Molybdenum(II) chloride cluster compounds. The emphasis of the text is on the hydrogen network in the different compounds. The main analysis tool has been single crystal x-ray diffraction, and in some cases theoretical calculations have been performed to confirm the hydrogen positions. LÄS MER

4. 3. A new synthetic strategy for low-dimensional compounds : Lone pair cations and alkaline earth spacers

   Författare :Rie Takagi Fredrickson; Mats Johnsson; Sven Lidin; Lars Kloo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkaline earth; Lone pair elements; Low-dimensional compounds; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. LÄS MER

5. 4. Structural investigation of Nb-based layer sulfides

   Författare :Alexander Grippa; Sven Lidin; Pedro Berastegui; Carlos Otero Díaz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nb-based sulfides; misfit layered; structure determination; electron diffraction; Chemistry; Kemi;

   Sammanfattning : In this work we have investigated the intercalation of electron-donors between NbS2 slabs in Nb-based layer sulfides.Two series of Sr substituted Nb-based misfit sulfides belonging to the 1.5Q/1H and 1Q/1H series of misfit layer compounds have been synthesised. LÄS MER

7. 5. Structural characterization of complex inorganic materials using solid-state NMR spectroscopy

   Författare :Hua Guo; Ulrich Häusserman; Sven Lidin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solid-state NMR; materials characterization; inorganic materials; Calcium phosphate cements; bone-substitution materials; Mixed-anion compounds; perovskite; Oxyhydride materials; Oxynitride materials; Barium titanate; Strontium vanadate; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Over the past decades, advancements in technology have relied greatly on the development of new functional inorganic materials. Detailed structural characterization of these materials is key for the understanding and also prediction of chemical and physical properties. LÄS MER
