1. The xanthophyll cycle, its enzymes, pigments and regulation
Sammanfattning : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

3. Colour-changing textile coatings containing multi-layered mica pigments : an experimental study
Sammanfattning : This study investigates the possibility of producing angle-dependent colour-changing textiles with thickened polyurethane (PU)-based aqueous dispersion containing multi-layered mica pigments using a direct coating method. Colour changing textile coatings with the latest generation of layered mica pigment (EP) have a promising future for functional purposes such as authentication and aesthetic eye-catching applications.

4. Pigment and Thiamine Dynamics in Marine Phytoplankton and Copepods
Sammanfattning : Based on a field study and several mesocosm experiments, I evaluated the use of pigments as chemotaxonomical biomarkers for phytoplankton community composition in the Baltic Sea and I examined effects of inorganic nutrients on the dynamics of carotenoids and thiamine (vitamin B1) at the phytoplankton–copepod level in marine pelagic food webs. My results show that HPLC pigment analysis combined with CHEMTAX data processing was an accurate alternative to microscopic analysis of Baltic Sea phytoplankton. LÄS MER
5. Effects of warming on the ecology of algal-dominated phytobenthic communities in the Baltic Sea
Sammanfattning : Through climate change, the global average air and surface water temperature has risen 0.85°C during the last 100 years. The Baltic Sea experienced one of the most rapid increase in temperature recorded of marine ecosystems. LÄS MER
