  4. 13. Symmetry of Halonium Complexes in Solution

    Författare :Anna-Carin Carlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bis pyridine -based halonium complexes; ethylenehalonium ions; structure symmetry; isotopic perturbation of equilibrium; solution NMR spectroscopy; isotope effects; N-X -N halogen bond; C-X -C interaction;

    Sammanfattning : In this thesis the symmetry of two interaction types involving electropositive halogens have been studied in solution; the N-X+-N halogen bond (X = Br or I), and the C-X+-C interaction of previously characterised, cyclic, 1,2-bridged halonium ions (X = Cl or Br), respectively. The three N-X+-N model structures included are bispyridine, 1,2-bis(pyridine-2-ylethynyl)benzene and 1,2-bis((4-methylpyridin-2-yl)ethynyl)benzene halonium triflate complexes. LÄS MER

    Författare :Andreas Bengtsson; Monica Ek; Maria Sedin; Elisabet Brännvall; Elisabeth Sjöholm; Johannes Ganster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Carbon fiber; Carbonization; Cellulose; Kraft pulp; Softwood kraft lignin; Solution spinning; Stabilization; Barrvedslignin; Cellulosa; Karbonisering; Kolfiber; Lösningsmedelsspinning; Stabilisering; Sulfatmassa; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Carbon fibers (CFs) have excellent mechanical properties and a low density, making themattractive as a reinforcing fiber in composites. The use of CFs is limited to high-end applications,since they are produced from an expensive fossil-based precursor via an energy-intensivemanufacturing process, explaining the need for cheaper CFs from renewables.
