  1. 6. Dynamics of Enzymes at Interfaces : Lipase adsorption and mobility on solid surfaces

    Författare :Andreas Sonesson; Hjalmar Brismar; Robert Tilton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; Physics; Fysik;

    Sammanfattning : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. LÄS MER

  3. 7. Adsorption of nonionic amphiphiles to solid surfaces

    Författare :Johanna Brinck; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; silica; solubilisation; self assembly; ellipsometry; mixed micelles; surfactant; kinetics; Adsorption; desorption; Fysikalisk kemi;

    Sammanfattning : In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. LÄS MER

  5. 9. Adhesion Mechanisms of Bacterial Spores to Solid Surfaces

    Författare :Ulrika Husmark; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The initial adhesion of different Bacillus spores to solid surfaces was investigated. By changing environmental parameters and studying the subsequent adhesion, conclusions have been drawn concerning the different mechanisms responsible for adhesion. Bacillus species are common microorganisms and in food industry they are common food spoilers. LÄS MER

  7. 10. Adsorption Properties of Triblock Copolymers at Solid Surfaces

    Författare :Krister Eskilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Ellipsomery; Surface force; Adsorption; Triblock Copolymer;

    Sammanfattning : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. LÄS MER
