  1. 1. X-Ray Diagnostics in Combustion - Study of Particle Formation in Flames Using Combined Small- and Wide-Angle X-Ray Scattering

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Linda Vallenhag; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; soot particles; WAXS; X-ray scattering; SAXS; combustion; Fysicumarkivet A:2014:Vallenhag;

    Abstract : In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtained.

  2. 2. Following nanoparticle self-assembly in real-time Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes

    University dissertation from Division of Combustion Physics, Department of Physics, Lund University

    Author : Martin Kapuscinski; Lennart Bergström; Niklas Hedin; Andrei Petukhov; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; mesocrystal; time-resolved; small-angle X-ray scattering; iron oxide nanocubes; QCM-D; materialkemi; Materials Chemistry;

    Abstract : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. READ MORE

  3. 3. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

    University dissertation from Institutionen för fysik, kemi och biologi

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

    University dissertation from Lund University (Media-Tryck)

    Author : Monika Witala; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE
