  1. 1. Electron transfer and fragmentation in fullerene collisions

    Författare :Henning Zettergren; Henrik Cederquist; Paul-Antoine Hervieux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fullerene; Physics; Fysik;

    Sammanfattning : In this thesis, we present results from detailed gas phase studies of intrinsic properties of fullerenes (C60) and clusters of fullerenes as probed by slow multiply charged (atomic or cluster) ions in combination with coincidence time-of-flight mass spectrometry. We have investigated the structures, stabilities, and the electron mobilities of multiply charged clusters of fullerenes, (C60)nr+ (r=2-5). LÄS MER

  3. 2. Exploring Molecular Interactions : Synthesis and Studies of Clip-Shaped Molecular Hosts

    Författare :Anjaneya Prasad Polavarapu; Helena Grennberg; Adolf Gogoll; Jerker Mårtensson; Uppsala universitet; []
    Nyckelord :Organic chemistry; Glycoluril clips; host-guest systems; supramolecular chemistry; complexation induced shifts; conformational restriction; NMR spectroscopy; fullerene binding; Organisk kemi;

    Sammanfattning : Molecular recognition via noncovalent interactions plays a key role in many biological processes such as antigen-antibody interactions, protein folding, the bonding and catalytic transformation of substrates by enzymes, etc. Amongst these noncovalent interactions, electrostatic interactions, hydrogen bonding, π-π interactions, and metal-to-ligand bonding are the most prominent.

  5. 4. Carbohydrate-Functionalized Nanomaterials : Synthesis, Characterization and Biorecognition Studies

    Författare :Na Kong; Mingdi Yan; Joseph J. Barchi Jr; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrate; glyconanomaterials; perfluorophenyl azide PFPA ; CuAAC; AAAC; coupling chemistry; 19 F q NMR; lectin; carbon nanomaterials; microwave irradiation; Kemi; Chemistry; Bioteknologi; Biotechnology;

    Sammanfattning : This thesis focuses on the development of carbohydrate coupling chemistry on nanomaterials and their biological activity studies. It is divided into two parts:In part one, two carbohydrate immobilization approaches, based on perfluorophenyl azide (PFPA)-functionalized silica nanoparticles (SNPs), are presented, where the binding affinity of the glyconanoparticles was evaluated through carbohydrate-lectin interaction.

  7. 5. Shining Light on Molecules : Electron Transfer Processes in Model Systems for Solar Energy Conversion Investigated by Transient Absorption Spectroscopy

    Författare :Jens Föhlinger; Leif Hammarström; Davidsson Jan; Benjamin Dietzek; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photophysics; photoinduced electron transfer; transient absorption spectroscopy; laser spectroscopy; solar energy conversion; p-type DSSCs; Charge separation; recombination; mesoporous NiO;

    Sammanfattning : In the recent years, solar energy conversion has attracted a huge research interest due to the potential application for limiting the greenhouse effect. In many solar cells and solar fuel cells, understanding of charge transfer (CT) and recombination is important for future improvement of the overall efficiency. LÄS MER
