  1. 1. Light-Metal Hydrides for Hydrogen Storage

    Author : Martin Sahlberg; Yvonne Brandt Andersson; Björgvin Hjörvarsson; Björn Hauback; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Metal-hydrogen compounds; hydrides; hydrogen storage; X-ray diffraction; neutron diffraction; thermal desorption spectroscopy; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Demands for zero greenhouse-gas emission vehicles have sharpened with today’s increased focus on global warming. Hydrogen storage is a key technology for the implementation of hydrogen powered vehicles. READ MORE

  2. 2. Synthesis and characterisation of heterobimetallic erbium alkoxides

    Author : Maria Wijk; Jean Galy; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. READ MORE

  3. 3. Synthesis and Characterization of Nitrogen-rich Calcium α-Sialon Ceramics

    Author : Yanbing Cai; Saeid Esmaeilzadeh; Zhijian Shen; Elis Carlström; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen-rich; SiAlON; Sintering; Microstructure; Properties; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : In this thesis, a synthesis concept has been developed, which uses nitrogen-rich liquid phases for sintering of Ca-α-sialon ceramics. First, keeping the Si/Al ratios constant, the effects of N/O ratio on the properties and microstructure were investigated through a liquid phase sintering process. READ MORE

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

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

    Abstract : 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. READ MORE
