1. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering
Sammanfattning : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. LÄS MER
2. Ultrafast spin dynamics at the nanoscale : using coherent X-ray and terahertz radiation
Sammanfattning : The field of ultrafast magnetism is driven by the growing need for faster and more efficient magnetic data storage, which comprises the vast majority of the digital information worldwide. However, after more than two decades of intense research, the understanding of the fundamental physical processes governing the transfer of angular momentum necessary for magnetic switching, is still lacking, partially hampered by the appropriate experimental tools.

3. Structural Studies Of Materials Using Time-Resolved X-ray Diffraction
Sammanfattning : This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.

4. Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering
Sammanfattning : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. LÄS MER
5. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin
Sammanfattning : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. LÄS MER
