  2. 2. Self assembly of surfactants and polyelectrolytes in solution and at interfaces

    Författare :Luis Alejandro Bastardo Zambrano; Per Claesson; Jan Skov Pedersen; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Surfactant; polyelectrolyte; small–angle neutron scattering; static light scattering; dynamic light scattering; polyelectrolyte–surfactant association; protein; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. LÄS MER

  3. 3. Scattering Studies of Macromolecules in Solution

    Författare :David Löf; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

  4. 4. Light Scattering in Fiber-based Materials : a foundation for characterization of structural properties

    Författare :Tomas Linder; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Deeper knowledge of light propagation in fiber-based materials is fundamental in order to understand their optical appearance as well as for industrial applications. Light scattering measurements are appropriate in handling dynamic industrial environments and can provide information regarding structural properties. LÄS MER
