    Sammanfattning : Water is a complex liquid with many unusual properties. Our understanding of its physical, chemical and biological properties is greatly advanced after a century of dedicated research but there are still many unresolved questions. LÄS MER

  2. 2. Structure formation at solid/liquid interfaces : Understanding self-assembly and environmental challenges

    Författare :Shirin Nouhi; Adrian R. Rennie; Vassilios Kapaklis; Maja S. Hellsing; Ann Terry; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid liquid interface; neutron scattering; colloidal particles; self-assembly; perfluoroalkyl substance; Moringa seed proteins; adsorption; lamellar disorder; thermal fluctuations.;

    Sammanfattning : The work described in the present dissertation has explored the structure of particles and molecules at solid/liquid interfaces, aiming to understand the physics of self-organizing systems and use this knowledge to address some environmental issues. Surface-sensitive neutron scattering techniques, such as reflectometry and grazing incidence small angle scattering, have been used as the primary tool to investigate structures in proximity to an interface.

  4. 4. Molecular structure and dynamics of liquid water : Simulations complementing experiments

    Författare :Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.
