  4. 4. Properties of Protein and Polymer Systems

    Detta är en avhandling från Fredrik Carlsson, YKI, Ytkemiska Institutet AB, Box 5607, SE-114 86 Stockholm, SWEDEN

    Författare :Fredrik Carlsson; Lund University.; Lunds universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; lysozyme; mica; surface; dimerization; precipitation; aggregate; cluster; complex; polyelectrolyte; protein; polymer;

    Sammanfattning : Interactions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these systems.

  5. 5. Scattering Studies of Macromolecules in Solution

    Detta är en avhandling från Fredrik Carlsson, YKI, Ytkemiska Institutet AB, Box 5607, SE-114 86 Stockholm, SWEDEN

    Författare :David Löf; Lund University.; Lunds universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage lambda; Dynamic Light Scattering; Time-Resolved; Mixed Micelles; Nonionic Surfactant; Triblock Copolymer; Calorimetry; SLS; Rheology; DLS; SAXS;

    Sammanfattning : The sphere-to-rod transition of nonionic micelles of the PEO-PPO-PEO triblock copolymer P123 and the surfactant C12EO6 was studied using dynamic and static light scattering, small angel X-ray scattering, rheology and calorimetry. The transition temperature was dependent of the C12EO6/P123 molar ratio, which means that a larger content of C12EO6 yields a higher transition temperature. LÄS MER
