1. Interactions between Fe and organic matter and their impact on As(V) and P(V)
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
2. Spektrum av joniserat järn, Fe II, med astrofysiska tillämpningar
Sammanfattning : [abstract missing].... LÄS MER
3. Laboratory measurements of absolute oscillator strengths in Fe II
Sammanfattning : [abstract missing].... LÄS MER
4. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution
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. Unraveling the importance of thiol compounds on mercury speciation, uptake and transformation by the iron-reducer Geobacter sulfurreducens
Sammanfattning : The biogenic methylation of inorganic, divalent mercury (Hg(II)) by methylating microorganisms leads to formation and bioaccumulation of monomethyl mercury (MeHg) in the environment and can cause severe damage to ecosystems and human health. Diverse microorganisms carry the gene sequence hgcAB and are able to methylate Hg(II) intracellularly. LÄS MER
