  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; Lund University.; Lunds universitet.; [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. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Naureen Ghafoor; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer Mirrors; X-ray microscope; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : 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. READ MORE

  4. 4. 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

  5. 5. To reduce a ribonucleotide – Radical solutions in enzymology in form and function

    University dissertation from Department of Biochemistry and Structural Biology, Lund University

    Author : Oskar Aurelius; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide reductase; X-ray crystallography; Small-angle X-ray scattering; nucleotide metabolism; protein biophysics; metalloproteins; anaerobic enzymology;

    Abstract : It has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. READ MORE
