11. The short, excited life of tellurium : Lifetime analysis of excited states in the Te midshell region
Sammanfattning : In this licentiate thesis, lifetimes of low lying excited states in the midshell region of tellurium isotopes are discussed. The nuclear lifetimes are interesting properties to study, since they are inversely proportional to the transition probabilities, which contain information on the underlying structure of the nucleus.

12. Excited States of Carotenoids and Their Functions in Light Harvesting
Sammanfattning : The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. LÄS MER
13. Excited state dynamics in low-dimensional perovskite nanocrystals
Sammanfattning : Two-dimensional (2D) perovskites have emerged as promising building blocks for optoelectronic applications. To fabricate high-performance devices, the relation between the material structures and their function in terms of excited state and charge carrier dynamics need to be well understood. LÄS MER
14. Photochemistry of Eumelanin Precursors Role of Excited State Proton Transfer for UV Photoprotection
Sammanfattning : Melanin is an epidermal pigment commonly known to give darker skin coloration under sun exposure. It is also present in the hair, eyes, inner ear and brain. LÄS MER
15. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State
Sammanfattning : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. LÄS MER
