  1. 1. 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

  2. 2. The importance of being thin : perceived expectations from self and others and the effect on self-evaluation in girls with disordered eating

    Författare :Sanna Aila Gustafsson; Claes Norring; Lars Kjellin; Birgitta Edlund; Per Johnsson; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eating disorders; risk factors; protective factors; sociocultural factors; gender; perfectionism; personal standards; competitiveness; phenomenography.; MEDICINE; MEDICIN; Psychiatry; Psykiatri; Psychiatry; Psykiatri;

    Sammanfattning : The overall aims of this thesis were to examine personal standards, self-evaluation and attitudes to eating and weight in the development of disturbed eating in adolescent girls, and to examine how adolescent girls with a clinical eating disorder reflect upon and deal with perceived expectations in daily life.Studies I and II were quantitative studies, conducted in a population-based longitudinal study.

  3. 3. Studies of Acute Rejection Using Contrast Agents and Magnetic Resonance Imaging

    Författare :Eva Penno; Håkan Ahlström; Cecilia Johnsson; Lars Johansson; Peter Leander; Uppsala universitet; []
    Nyckelord :Radiology; Magnetic resonance imaging; contrast agents; organ transplantation; acute rejection; Radiologisk forskning;

    Sammanfattning : Solid organ transplantation is today an established form of treatment for end-stage organ disease. Monitoring of graft function and pharmacological therapy constitutes a maze of clinical observations and histological evaluations of biopsy specimens; with the biopsy results playing a decisive role.

  4. 4. 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.

  5. 5. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

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

    Sammanfattning : 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. LÄS MER
