  1. 1. Electrostatic Interactions in Complex Liquids : A Thermodynamic Analysis Based on the Poisson-Boltzmann Equation and the Flexible Surface Model

    Författare :Ingemar Carlsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOT; AerosolOT; ionic surfactant; spontaneous curvature; bending modulus; bending energy; Helfrich curvature energy; fluid membrane; complex liquid; flexible surface model; micelle; counterion; Poisson-Boltzmann equation; cell model; L3 phase; sponge phas; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study was to analyse physico-chemical properties of some complex liquids using the Poisson-Boltzmann (PB) cell model; to extend the theory to cover bilayer systems with complex global geometry; finally to apply this new extended model to such bilayer systems. The PB cell model provides a practical tool to examine counterion association and phase behaviour for structures of simple geometries; cylindrical and spherical. LÄS MER

  2. 2. Protein Folding Studied by Site Directed Mutagenesis

    Författare :Tomas Ternström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; Transition state; Activation Barrier; Two-State; Protein Folding; Protein Engineering;

    Sammanfattning : The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. LÄS MER

  3. 3. Adsorption and Ordering of Surface Active Molecules and Particles at Solid Interfaces and in the Bulk

    Författare :Maja S. Hellsing; Adrian R. Rennie; Jöns Hilborn; Julia Higgins; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Factors that influence the process of adsorption and order of dilute and concentrated systems of molecules and particles are explored in this thesis.  The results are based largely on neutron scattering techniques. LÄS MER

  4. 4. Effects of a Novel Amphiphilic Graft Copolymer on Ternary Mixtures of Surfactant, Water, and Oil

    Författare :Anna Holmberg; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TRFQ; PFG NMR; molecular self-diffusion; phase behavior; viscosity; amphiphilic polymer; oil-continuous microemulsion; light scattering; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. LÄS MER
