  1. 1. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics

    Författare :Lars-Erik Enarsson; Lars Wågberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte adsorption; adsorption kinetics; adsorption isotherms; conformation; bridging; stagnation point adsorption reflectometry; quartz crystal microgravimetry; polyelectrolyte titration; cationic polyacrylamide; cationic dextran; colloidal silica; silica surfaces; pulp; Chemistry; Kemi;

    Sammanfattning : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra.

  3. 2. Stochastic systems with locally defined dynamics

    Författare :Anton Muratov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; point process; sequential adsorption; stopping set; random measure; Polya urn; convergence of empirical measures; bit flipping; recurrence; mixing times; sequential adsorption;

    Sammanfattning : This thesis considers two large classes of models related to the dynamical point processes. The first is the locally interactive sequential adsorption, or LISA, models. LÄS MER

  4. 3. In vitro and in vivo studies of salivary films at solid/liquid interfaces

    Författare :Ida Svendsen; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; saliva; proteins; adsorption; ellipsometry; gel electrophoresis;

    Sammanfattning : A conditioning film, the pellicle, of which many salivary proteins areimportant constituents, covers the surfaces present in the mouth. The pellicleforms in a selective adsorption process, and it has protective and lubricatingfunctions as well as an influence on the adherence of oral microbes thatultimately leads to the development of dental plaque.

  5. 4. Wheat Storage Proteins at Interfaces

    Författare :Jörgen Örnebro; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; adsorption; surfaces; interfaces; gliadins; glutenins; Livsmedelsteknik;

    Sammanfattning : This thesis deals with the properties of wheat storage proteins at interfaces. These proteins are the main constituents of gluten and are recognised for their importance in breadmaking. LÄS MER

  7. 5. Stochastic systems with locally defined dynamics

    Författare :Anton Muratov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; point process; sequential adsorption; stopping set; random measure; Polya urn; convergence of empirical measures; bit flipping; recurrence; renewal process; Poisson process; Dirichlet distribution; random matrices; random matrices;

    Sammanfattning : We study three different classes of models of stochastic systems with locally defined dynamics. Our main points of interest are the limiting properties and convergence in these models. The first class is the locally interactive sequential adsorption, or LISA, models. LÄS MER
