21. Dynamics of Excitation Transfer and Charge Separation in Polymeric Semiconductors
Sammanfattning : Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. LÄS MER
22. Shining Light on Molecules : Electron Transfer Processes in Model Systems for Solar Energy Conversion Investigated by Transient Absorption Spectroscopy
Sammanfattning : In the recent years, solar energy conversion has attracted a huge research interest due to the potential application for limiting the greenhouse effect. In many solar cells and solar fuel cells, understanding of charge transfer (CT) and recombination is important for future improvement of the overall efficiency. LÄS MER
23. Evolution of human alpha-herpesviruses
Sammanfattning : Herpesviridae is a large virus family with more than 100 members, which are highly disseminated among animals. Three sub-families have been classified; alpha-herpesviruses, beta-herpesviruses and gamma-herpesviruses. LÄS MER
24. Chicken Genomics - Linkage and QTL mapping
Sammanfattning : This thesis presents results from genetic studies conducted in the chicken (Gallus gallus). The domestication of chicken is believed to have been initiated approximately 7,000 – 9,000 years ago in Southeast Asia. LÄS MER
25. The genomic signatures of adaptive evolution in Populus
Sammanfattning : Understanding the genetic basis of adaptive evolution, and how natural selection has shaped patterns of polymorphism and divergence within and between species are enduring goals of evolutionary genetics. In this thesis, I used whole genome re-sequencing data to characterize the genomic signatures of natural selection along different evolutionary timescales in three Populus species: Populus tremula, P.
