    Författare :Tofeeq Ur-Rehman; Gerhard Gröbner; Mikael Elofsson; Åsa Gylfe; Martin Malmsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; poloxamer; drug delivery; micellization; DMSO; calorimetry; NMR. in situ gelation; chitosan; preclinical pharmacokinetics; type III secretion inhibitors; Physical chemistry; Fysikalisk kemi; Pharmaceutics; galenisk farmaci;

    Sammanfattning : Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermo-reversible poloxamer gels, which are suitable for novel drug delivery applications.

    Författare :Britta M. Folmer; KTH; []
    Nyckelord :Natural raw materials; novel hydrophobes; physico-chemical characterisation; micelles; interfacial adsorption; liquid crystals; enzymes; polymers; complex formation; foam;

    Sammanfattning : The aim of this thesis has been to investigate thephysico-chemical behaviour of novel surfactants based onnatural raw materials. Micellization properties, adsorptionatinterfaces and dynamic aspects have been studied. In additioncomplex formation of surfactants with enzymes and polymers hasbeen evaluated. LÄS MER

  5. 4. Adsorption and Self-Assembly of Cationic Surfactants at Silica Surfaces

    Författare :Cecilia Ström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). LÄS MER

  7. 5. Self aggregation of fluorocarbon surfactants and fluorocarbon- hydrocarbon surfactant mixtures

    Författare :Ke Wang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : The aggregation and phase behavior of fluorocarbon surfactants in micellar, and liquid crystalline phases, and micellization in nonideal mixed fluorocarbon-hydrocarbon surfactant system have been investigated by means of a variety of techniques.The demixing in mixed surfactant systems was studied in the dilute solution region by using time-resolved fluorescence quenching measurements.
