2. Cellulose degradation in pulp fibers studied as changes in molar mass distributions
Abstract : In this thesis, size-exclusion chromatography (SEC) of woodpolymers dissolved in lithium chloride/N,N-dimethylacetamide(LiCl/DMAc) has been used to characterize the molar massdistributions (MMD) of wood polymers in pulp fibers afterchemical degradation.Characterization of birch kraft pulps subjected to ozonedegradation and acid hydrolysis, respectively, rendereddifferent changes in the MMD.

3. Electrode Degradation in Polymer Electrolyte Fuel Cells
Abstract : To mitigate the climate crisis, and reduce carbon emissions from e.g. the transport and energy sectors, hydrogen has been proposed to be used as an environmentally friendly alternative energy carrier. READ MORE

4. Studies on the Effect of Concrete on the Chemistry in a Repository for Radioactive Waste
Abstract : In Sweden, the disposal method for long-lived low- to intermediate-level radioactive waste is proposed to be the long-term storage of the waste in a concrete repository deep in a geological formation. The use of concrete and steel for the waste containment will affect the chemical conditions inside the repository and in the host rock. READ MORE

5. Metal distribution and mobility under alkaline conditions
Abstract : The adsorption of an element, expressed as its distribution between liquid (aquatic) and solid phases in the biogeosphere, largely determines its mobility and transport properties. This is of fundamental importance in the assessment of the performance of e.g. geologic repositories for hazardous elements like radionuclides. READ MORE
