    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Characterization of interfaces by elastic light scattering and profilometry

    Författare :Tomas Lindström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This thesis deals with the characterization of interfaces by elastic light scattering and profilometry. The sensitivity of scattering measurements to surface topography were used in two major ways. It was shown that surface reactions in a liquid-solid interface can be monitored in situ in terms of changes in surface roughness. LÄS MER

  5. 4. Light scattering and absorption in pigmented coatings : Theory and experiments

    Författare :William E. Vargas; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. LÄS MER

  7. 5. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties

    Författare :Joakim Balogh; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Light Scattering; NMR relaxation NMR self-diffusion; SANS contrast variation and contrast matched studies; saddle play modulus; made by C12E5; Nonionic microemulsion; balanced microemulsion; Fysikalisk kemi;

    Sammanfattning : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. LÄS MER
