11. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites
Sammanfattning : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

12. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins
Sammanfattning : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. LÄS MER
13. Imidazole containing polymers complexed with Cu2+ and Zn2+
Sammanfattning : An enormous problem for the shipping industry is fouling of marine organisms such as algae andbarnacles on the boat hull. The negative consequences for the society are both economical as well asenvironmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER
14. Electronic Structure of Transition Metal Complexes in Silicon
Sammanfattning : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. LÄS MER
15. Hydrogen in nominally anhydrous silicate minerals : Quantification methods, incorporation mechanisms and geological applications
Sammanfattning : The aim of this thesis is to increase our knowledge and understanding of trace water concentrations in nominally anhydrous minerals (NAMs). Special focus is put on the de- and rehydration mechanisms of clinopyroxene crystals in volcanic systems, how these minerals can be used to investigate the volatile content of mantle rocks and melts on both Earth and other planetary bodies (e.
