1. Life of Excitons in Artificial Photosynthetic Antennas
Sammanfattning : Due to the predicted energy crisis when fossil fuels will be exhausted it is important to search for alternative energy sources. Utilizing sunlight via artificial photosynthesis is an interesting possibility. LÄS MER
2. Big Lessons from Small Bacteria : Following Photo-driven Processes in Photosynthetic Systems with Multidimensional Spectroscopy
Sammanfattning : Sunlight is a plentiful, continuously flowing source of energy, fuelling life on Earth as we know it. To use this potential, plants, cyanobacteria and photosynthetic bacteria evolved to absorb solar radiance and convert it into a chemically stable form by performing a process known as photosynthesis.

3. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging
Sammanfattning : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

4. Quantum Coherence for Light Harvesting
Sammanfattning : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. LÄS MER
5. Electron and Energy Transfer in Supramolecular Complexes Designed for Artificial Photosynthesis
Sammanfattning : In the society of today the need for alternative energy sources is increasing. The construction of artificial devices for the conversion of sunlight into electricity or fuel seems very attractive from an environmental point of view, since these devices are based on processes that does not necessarily generate any harmful biproducts.
