    Keywords : Physics; Magnetism; Multilayer; Superlattice; X-ray magnetic circular dichroism; X-ray diffraction; X-ray reflectivity; Neutron diffraction; Structural refinement; Interfaces; Fysik;

    Abstract : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. READ MORE

  5. 3. Adsorption and Ordering of Surface Active Molecules and Particles at Solid Interfaces and in the Bulk

    Author : Maja S. Hellsing; Adrian R. Rennie; Jöns Hilborn; Julia Higgins; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Factors that influence the process of adsorption and order of dilute and concentrated systems of molecules and particles are explored in this thesis.  The results are based largely on neutron scattering techniques. READ MORE

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

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

    Abstract : 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.
