Study of solid fraction of the atmospheric aerosol of Pilsen by X-ray powder diffraction
Vik, Ondřej ; Havlíček, David (advisor) ; Plocek, Jiří (referee)
In this diploma thesis there was studied a composition of a solid fraction of the atmospheric aerosol of the daily measurements from Pilsen by X-ray powder diffraction by the method of the parallel beam. The phase analysis was accomplished by comparing of the diffraction dates with a database of compounds usually occurring in the solid fraction of the atmospheric aerosol in this area. This database was created from works published earlier. In these samples there were also identified asbestos fibers of actinolite by the scanning electron microscope with EDS module. In this thesis there was also described a transport of several anthropogenic compounds of the atmospheric aerosol in dependence on a meteorological situation. Powered by TCPDF (www.tcpdf.org)
High-temperature X-ray Diffractometry of Thin Layers
Valeš, Václav ; Holý, Václav (advisor) ; Jergel, Matej (referee) ; Nižňanský, Daniel (referee)
In this work, the crystallographic structure and its changes under thermal treatment of different systems consisting of metal oxide nanoparticles is studied. The principal method used throughout the thesis is x-ray powder diffraction enriched with grazing incidence small angle x-ray scattering when the nanoparticles form an ordered structure or with x-ray absorption spectroscopy when additional information on local crystallographic structure is required. For all the systems the preparation conditions were optimized according to the crystallographic data for further applications.
