21. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration
Abstract : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. READ MORE

22. Fundamental interactions in transition metal reactions
Abstract : Transition metal complexes that participate in homogeneous reactions often perform the role of a catalyst, facilitating novel reaction pathways. When these complexes are pushed away from their equilibrium, the arrangement of the coordinating ligands around the metal center is perturbed and new reaction pathways are opened. READ MORE

23. Chromatin Dynamics in the Fission Yeast, Schizosaccharomyces pombe
Abstract : In the eukaryotic cell nucleus, spatial organization and dynamics of the genome is important in the regulation of gene expression. This thesis describes the use of the fission yeast, Schizosaccharomyces pombe, to study chromatin regulation and dynamics. We used nitrogen starvation to induce transcription of genes in fission yeast cells. READ MORE

24. Collision- and photon-induced dynamics of complex molecular ions in the gas phase
Abstract : In this thesis, I report experiments probing collision- and photon-induced molecular dynamics in the gas phase. Excited molecules formed in such interactions may relax by emitting electrons or photons, isomerization or fragmentation. READ MORE

25. Ultrafast Magnetization Dynamics : Element-selective studies of magnetic alloys using ultra short XUV pulses
Abstract : In this thesis, I investigate the ultrafast magnetization dynamics in 3d ferromagnets and their alloys with ultrashort laser pulses. The high harmonics generation (HHG) setup provides extreme-ultraviolet photons with energies 35-72 eV, which is the energy range where 3d metals have their M2,3 absorption edges. READ MORE
