  2. 16. Dynamics of Disordered Materials in Confined Geometries

    Author : Christer Svanberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer film; glass transition; confinement; polymer gel; dynamics; dielectric spectroscopy; gel electrolytes; relaxation; photon correlation; cooperativity;

    Abstract : This thesis is concerned with effects of geometrical confinement on dynamics in disordered materials in the nanoscopic range. Of particular interest is the dynamics around the liquid to glass transition. Two systems have been investigated: thin polymer films and polymer gels. READ MORE

  4. 17. Concentrated DNA-amphiphiles Structure, Hydration, and Dynamics

    Author : Cecilia Leal; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amphiphiles; DNA; Physical chemistry; diffusion NMR; solid-state NMR; electrostatics; dynamics; local order; Fysikalisk kemi; hydration;

    Abstract : The structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. READ MORE

  5. 18. Get a grip on chaos : Tailored measures for complex systems on surfaces

    Author : Sascha Firle; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; complex systems; chaos; predator prey; movement models; functional response; spatial heterogeneity; topological dynamics; braid template; homoclinic bifurcations; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; kvantkemi;

    Abstract : Complex systems are ubiquitous in physics, biology and mathematics. This thesis is concerned with describing and understanding complex systems. Some new concepts about how large systems can be viewed in a lower dimensional framework are proposed. The systems presented are examples from ecology and chemistry. READ MORE

  6. 19. Dynamics of biological membranes and associated water

    Author : Peter Berntsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric spectroscopy; phase transition; glass transition; DSC; lipid bilayers; lipid dynamics; water dynamics; purple membrane; diffusion; polarisation; QENS.; relaxation; long-range conductivity;

    Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE

  7. 20. Latex Colloid Dynamics in Complex Dispersions : Fluorescence Microscopy Applied to Coating Color Model Systems

    Author : Gunilla Carlsson; Jan van Stam; Maria da Graca Miguel; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; coating color; colloid; latex; diffusion; Brownian motion; film formation; polymer interaction; Physical chemistry; Fysikalisk kemi; Kemi; Chemistry;

    Abstract : Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential.. READ MORE
