  1. 1. PREPARATION AND CHARACTERIZATION OF EPOXY-BASED MONOLITHIC SORBENTS FOR CHROMATOGRAPHY

    Magister-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Trung Quoc Nguyen; [2021]
    Nyckelord :;

    Sammanfattning : This ‘scouting’ work aimed to investigate the possibility of using non-aromatic monomers to prepare porous monolithic materials by utilizing varying compositions under spinodal decomposition and step polymerization. 1,3,5-Triglycidyl isocyanurate (TEPIC) was employed as a main molecular structural scaffold.

    Sammanfattning : The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. LÄS MER

  4. 3. Geometrical and Electronic Structure Characterization of Conducting Hydroquinone Substituted Polypyrrole

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Anton Segerkvist; [2016]
    Nyckelord :;

    Sammanfattning : The fundamental electronic and geometric structures of charged polypyrrole and a hydroquinone substituted polypyrrole, poly(pyrrol-3-ylhydroquinone), were investigated. A single electron was constrained over different sizes of the polymer chains, a polaron, with the purpose of finding the polaron size which minimizes the excitation energy. LÄS MER
