    Sammanfattning : Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes.

  2. 2. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Detta är en avhandling från Physical Chemistry 1, Lund University

    Författare :Anna Karin Morén; Lunds universitet.; Lund University.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-surfactant interactions; Phase equilibria; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. LÄS MER

  3. 3. Theoretical Studies of Surface Forces and Phase Equilibria

    Detta är en avhandling från Physical Chemistry 2, Lund University

    Författare :Jan Forsman; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulations; density functional theory; phase equilibria; hydrophobic interactions; hydration; Fysikalisk kemi; Physical chemistry;

    Sammanfattning : The interaction between large hydrophobic and hydrophilic surfaces in aqueous solution is investigated, using Metropolis Monte Carlo simulations and density functional theory. Special attention is devoted to the solvation force and its dependence on the nature of the solvent-solvent and solvent-surface interactions. LÄS MER
