2. Cobalt and Nickel Bioavailability for Biogas Formation
Abstract : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. READ MORE

4. Determination of mercury chemical speciation in the presence of low molecular mass thiols and its importance for mercury methylation
Abstract : Methylmercury (MeHg) is a neurotoxic compound that threatens the well-being of humans and wildlife. It is formed through the methylation of inorganic mercury (HgII) under suboxic/anoxic conditions in soils, sediment and waters. READ MORE

5. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution
Abstract : 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. READ MORE
