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

    Author : Tomas Linder; Stefan Andersson-Engels; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : 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. READ MORE

  5. 3. Self assembly of surfactants and polyelectrolytes in solution and at interfaces

    Author : Luis Alejandro Bastardo Zambrano; Per Claesson; Jan Skov Pedersen; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Equilibrium and Nonequilibrium Properties of Nonionic Surfactant Membranes

    Author : Thao Le; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lamellar; multilamellar vesicle; small-angle x-ray scattering SAXS ; small-angle neutron scattering SANS ; static light scattering SLS ; joule heating temperature jump JHTJ ; dynamic light scattering DLS ; Nonionic surfactants; sponge; elastic curvature energy; Physical chemistry; Fysikalisk kemi;

    Abstract : An extensive investigation of the multilamellar vesicles (La*), lamellar (La), and multiply connected sponge (L3) phase formed in surfactant systems is presented in this thesis. These membrane structures were studied using surfactant systems containing poly(oxyethylene) alkyl ethers, n-CnH2n+1(OCH2CH2) mOH, commonly abbreviated as CnEm. READ MORE
