  1. 1. Quantum mechanical effects on charge transport in two mesoscopic systems

    Författare :Gustav Sonne; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; NEMS; carbon nanotubes; carbon peapods; excess current; superconducting weak links; suspended carbon nanotubes; non-linear resonances;

    Sammanfattning : Carbon nanotubes are one of the most promising building blocks for the developing field of nanoelectromechanics. Due to their unique electronic and mechanical properties, these all-carbon systems have been suggested for a range of applications where one wishes to utilse the coupling between mechanical and electronic degrees of freedom on the nanometer length scale.

  3. 2. 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

  4. 3. Materials for Hydrogen storage and synthesis of new materials by hydrogenation

    Författare :Serhiy Luzan; Alexandr Talyzin; Yaroslav Filinchuk; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fullerene C60; MOFs; CNTs; SWCNTs; PAHs; peapods; hydrogen; hydrogen storage; hydrogenation; adsorption; surface area; pore volume; spillover; nanoribbons; fragmentation; fysikalisk kemi; Physical Chemistry; fysik; Physics;

    Sammanfattning : The search for new materials for hydrogen storage is important for the development of future hydrogen energy applications. In this Thesis, it is shown that new materials with interesting properties can be synthesized by the reaction of hydrogen with various nanocarbon precursors. The thesis consists of two parts. LÄS MER
