  1. 1. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    Författare :Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; Materials Chemistry; materialkemi;

    Sammanfattning : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.

  3. 2. Ion Solvation in Critical Binary Aqueous Solvents Probed by Advanced Synchrotron-Based Techniques

    Författare :Monika Witala; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; preferential ion solvation; microscopic segregation of hydrophilic ions; ion size asymmetry; critical binary liquid mixtures; 2; 6-dimethylpyridine; potassium chloride; grazing-incidence x-ray fluorescence; small-angle x-ray scattering; mesoscale ordering; x-ray beam-induced local heating;

    Sammanfattning : The Poisson-Boltzmann equation is the standard tool for studying the electrostatic interactions in electrolyte solutions, although it neglects e.g. the ion size and ion-ion correlations. Even experimentally observed specific ion effects cannot be explained in a view of this approximation. LÄS MER
