6. Processing and properties of nanocomposites based on polylactic acid, chitin and cellulose
Sammanfattning : The production of bio-based and biodegradable nanocomposites has gained attention during recent years for environmental reasons; however, the large-scale production of these nanocomposites still poses challenges. The objective of this work has been to prepare bio-based and biodegradable nanocomposites via liquid-assisted extrusion and to gain a deeper understanding of the process and the relationship between the process, composition, structure and properties.

7. Zooplankton growth and trophic linkages : Implications for fish feeding conditions in the Baltic Sea
Sammanfattning : The aim of this Thesis was to improve our understanding and assessment of feeding conditions for zooplanktivorous fish in the Baltic Sea.We investigated (papers I, II) the usefulness of biochemical proxies for assessments of growth and metabolic rates in the dominant Baltic copepod Acartia bifilosa.

8. On the role of microstructure in wear of nanostructured carbide-free bainitic steels
Sammanfattning : The significance of steel production for the development of sustainable society and economy is immense. Today’s fast growing global economy poses an increasing demand for improving the properties of steel. LÄS MER
9. Cracking during Continuous Casting of Steels : Analysis tools and procedures to identify their causes on microalloyed steel slabs
Sammanfattning : Transverse corner cracks are one of the most common but complex defects formed in microalloyed steels during continuous casting (CC). Such cracks are detrimental because it leads to a loss in productivity with a great impact on environment, energy and economics for several steel making companies all over the world. LÄS MER
10. Properties and performance of regenerated cellulose thermoset biocomposites
Sammanfattning : Biocomposites have been developed to address the sustainability issues of nonrenewableresource based materials. These composites are often produced by reinforcing natural fibres in petroleum based thermoset resins or thermoplastic polymers. LÄS MER
