  1. 1. Hydrogeochemistry of Fe and Mn in small boreal catchments

    Author : Louise Björkvald; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogeochemistry; Fe; Mn; boreal catchments; spring flood; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap;

    Abstract : It is suggested that the overall understanding of the general hydrogeochemistry of a region is best understood from a landscape perspective. If so, this can provide useful information when planning monitoring programmes and influence of human activity. READ MORE

  2. 2. Surface structure and catalytic activity of Pd and Fe oxide surfaces and thin films

    University dissertation from Lund University, Faculty of Science, Department of Physics, Division of Synchrotron Radiation Research

    Author : Mikhail Shipilin; [2016-10]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface X-ray diffraction SXRD ; Heterogeneous catalysis; Pd; PdO; Fe; FeO; Thin films; Fysicumarkivet A:2016:Shipilin;

    Abstract : The present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO oxidation under semirealistic conditions.

    Abstract : The transport of elements by streams from headwater regions to the sea is influenced by landscape characteristics. This thesis focuses on the influence of landscape characteristics (e.g. READ MORE

  5. 5. Simulation of radiation damage in Fe and Fe-Cr

    University dissertation from Stockholm : KTH

    Author : Christina Lagerstedt; Jan Wallenius; Cristophe Domain; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Steel is an important structural material in nuclear reactors used for example in pressure vessels and fast reactor cladding. In reactor environments it has been observed that ferritic steels are more resistant to swelling than the austenitic steels typically used. READ MORE
