16. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation
Abstract : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. READ MORE

17. Molecules and Light : A Journey into the World of Theoretical Spectroscopy
Abstract : Two of the main technological challenges of the century are the production of clean energy, on the one hand, and the development of new materials for electronic and spintronic applications that could increase the speed and the storage capacity of regular electronic devices, on the other hand. Organic materials, including fullerenes, organic polymers and organic molecules with metal centres are promising candidates for low-cost, flexible and clean technologies that can address these challenges.

19. The Light-up Probe
Abstract : The work presented in this thesis concerns the development of light-up probes and their potential applications in PCR based molecular diagnostics. The light-up probe is a nucleic acid analog (here PNA) oligomer linked to an asymmetric cyanine dye (here thiazole orange) and it combines the excellent hybridization properties of PNA with the large fluorescence enhancement of the dye upon binding to DNA.

20. Polymer Light Emitting Devices : A study on how the electrode-polymer interface affects the performance of polymer light emitting devices
Abstract : The research reported in this thesis is concerned with a new type of semiconductor device that can be realised by using thin films of semiconducting polymers, or conjugated polymers. In this thesis only one family of these conjugated polymers is studied, namely poly-(para-phenylene vinylene) and derivatives thereof. READ MORE
