  1. 1. Interactions between Fe and organic matter and their impact on As(V) and P(V)

    Författare :Anneli Sundman; Per Persson; Thomas Borch; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; XAS; Fe III ; As V ; P V ; natural organic matter; Fe II; III -NOM complexes; Krycklan catchment; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Iron (Fe) speciation is important for many biogeochemical processes. The high abundance and limited solubility of Fe(III) are responsible for the widespread occurrence of Fe(III) minerals in the environment. LÄS MER

  4. 4. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution

    Författare :Daniel Svensson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; bentonite; smectite; freezing; thawing; hydration; intercalation; four-water-layer; ethylene glycol; X-ray diffraction; time-resolved; spatial-resolution; XANES; Fe; redox; iron; ABM; TBT; Äspö;

    Sammanfattning : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. LÄS MER

  5. 5. Beyond Classical Ruthenium(II) Polypyridyl Complexes : Photosensitizers as Building Blocks For Linear Donor-Photosensitizer-Acceptor Assemblies

    Författare :Michael Jäger; Olof Johansson; Edwin Constable; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi;

    Sammanfattning : This thesis describes ruthenium(II) polypyridyl-type complexes tailored for artificial photosynthesis. Inspired by Nature, the primary events in photosystem II are mimicked by donor-photosensitizer-acceptor (D-P-A) assemblies. LÄS MER
