  1. 1. Protein-surfactant interactions

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ank Valstar; Uppsala universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. LÄS MER

    Sammanfattning : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. LÄS MER

  5. 5. Environmentally Responsive Surface Coatings of Polyion-Surfactant Ion Complex Salts

    Detta är en avhandling från Division of Physical Chemistry, Faculty of Science, Lund University

    Författare :Charlotte Gustavsson; Lund University.; Lunds universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer; polyelectrolyte; surfactant; complex salt; surface coatings; phase behaviour; responsivness; hydration; SAXS; water-insoluble; solutes; liquid crystalline structures;

    Sammanfattning : Complexes formed between oppositely charged polyions and surfactant ions are known to have very rich phase behaviour in bulk solution. The work in this thesis investigates the possibilites of using such complexes as surface coatings. LÄS MER
