  1. 1. Influence of Self-trapping, Clamping and Confinement on Hydrogen Absorption

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gunnar Karl Pálsson; Björgvin Hjörvarsson; Keith Ross; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen diffusion; thin films; superlattices; phase transitions; confinement; clamping; self-trapping; finite-size effect; NATURAL SCIENCES Physics Condensed matter physics Surfaces and interfaces; NATURVETENSKAP Fysik Kondenserade materiens fysik Ytor och mellanytor; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The dissociation of hydrogen molecules at surfaces is the first step in the absorption process. If the absorbing material is covered by an oxide, this layer will determine the effective uptake rate of an underlying absorbing material. READ MORE

  2. 2. Statistical Physics of DNA: Melting and Confinement Effects

    University dissertation from Department of Astronomy and Theoretical Physics, Lund University

    Author : Michaela Reiter-Schad; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; DNA melting; DNA confinement; random walk; Fysicumarkivet A:2015:Reiter-Scad;

    Abstract : Investigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. READ MORE

  3. 3. Dynamics of Disordered Materials in Confined Geometries

    University dissertation from Department of Astronomy and Theoretical Physics, Lund University

    Author : Christer Svanberg; [2000]
    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. 4. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars

    University dissertation from Department of Astronomy and Theoretical Physics, Lund University

    Author : Ralejs Tepfers; [1973]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; splitting failures; confinement; deformed bars; tensile overlap splices; bond theory; fatigue; concrete cover splitting; reinforcement;

    Abstract : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. READ MORE

  5. 5. Phase Separation and Gelation of Biopolymers in Confined Geometries

    University dissertation from Department of Astronomy and Theoretical Physics, Lund University

    Author : Sophia Wassén; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

    Abstract : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. READ MORE
