  1. 1. Fullerene γ-Cyclodextrin Complexes

    Författare :Thomas Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C60; a-cyclodextrin; aggregates; FAB LSIMS; Buckminsterfullerene; g-cyclodextrin; b-cyclodextrin; ring-currents; fullerene; host-guest; C70;

    Sammanfattning : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . LÄS MER

  3. 2. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment

    Författare :Alexandr Talyzin; B. Sundqvist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; fullerene; solution; high pressure; Raman spectroscopy; polymerisation; XRD; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. LÄS MER

  4. 3. Glass-forming ternary blends: towards stable Polymer Solar Cells

    Författare :Amaia Diaz de Zerio Mendaza; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic photovoltaics; glass formation.; fullerenes; ternary blends; thermal stability;

    Sammanfattning : The globally increasing use of electricity goes hand in hand with climate change and the gradual depletion of fossil sources of fuel. To address these challenges renewable sources of energy are in high demand. LÄS MER

  5. 4. Studies of carbon nanomaterials based on fullerenes and carbon nanotubes

    Författare :Agnieszka Iwasiewicz-Wabnig; Bertil Sundqvist; Eleanor E.B. Campbell; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fullerenes; carbon nanotubes; fullerene polymers; intercalation compounds; high pressure; Raman spectroscopy; X-ray diffraction; atomic force microscopy; phase transitions; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : Materials based on fullerenes and carbon nanotubes are very much different from most “traditional” materials, primarily because they are built from nanosized molecules with highly symmetry-dependent properties. Being the subject of a very active research field over the last twenty years, carbon nanostructures proved to be indeed extraordinary. LÄS MER

  7. 5. Selectivity in Host-Guest Chemistry

    Författare :Gunnar Westman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes host-guest complexes with the use of a biphenyl crown ether or cyclodextrin as host. Complexes between the biphenyl crown ether and salts form phenylalanine esters were studied. LÄS MER
