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

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

    Sammanfattning : 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.

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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Naureen Ghafoor; Jens Birch; Gabriella Andesson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Soft X-rays; Multilayer Mirrors; X-ray microscope; Materials science; Teknisk materialvetenskap;

    Sammanfattning : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. LÄS MER
