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

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

    Abstract : 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. READ MORE

  4. 7. Adsorption of nonionic amphiphiles to solid surfaces

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

    Abstract : 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. READ MORE

  5. 8. Drop impact on solid and liquid surfaces

    Author : Ronny Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : .... READ MORE

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

    Author : Ulrika Husmark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
