6. Engineering of the Ultra-stable Cystine Knot Framework of Microproteins : Design, Chemical Synthesis and Structural Studies
Sammanfattning : Ultra-stable cystine knotted microproteins, in which two disulfides and their connecting backbones form a circle that is penetrated by the third disulfide bonds, have attracted high interest due to their resistance to degradation in vitro and potential for the development of peptide drugs. This thesis gives new insights into engineering of that framework of microproteins, including approaches to their chemical synthesis, backbone engineering, structural and biological evaluations.

7. Heterogeneous Technologies for Microfluidic Systems
Sammanfattning : In this thesis, conventional and unconventional technologies have been studied and combined in order to make heterogeneous microfluidics with potential advantages, especially in biological applications. Many conventional materials, like silicon, glass, thermoplastic polymers, polyimide and polydimethylsiloxane (PDMS) have been combined in building heterogeneous microfluidic devices or demonstrators.

8. A Quest for the Unseen : Surface Layer Formation on Li4Ti5O12 Li-Ion Battery Anodes
Sammanfattning : The electric vehicle itself today outlives its battery, necessitating battery replacement. Lithium titanium oxide (LTO) has, in this context, been suggested as a new anode material in heavy electric vehicle applications due to intrinsic properties regarding safety, lifetime and availability.

9. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints
Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER
10. Photoinduced Electron Transfer in Luminescent Lanthanide Complexes
Sammanfattning : Luminescence from the trivalent lanthanides is used for detection in biological systems. Lanthanide luminescence is usually sensitized by a light-harvesting organic chromophore (’antenna’). An ideal emitter has an antenna that efficiently transfers energy to the lanthanide, and a ligand that shields the metal from quenching solvent molecules. LÄS MER
