1. On the accuracy of crystal structural analysis and the potential of unraveling structural details by 3D electron diffraction
Sammanfattning : Knowing the atomic crystal structures of ordered porous solids is essential in understanding their behaviors and properties, developing new applications, and designing new porous materials. Electrons have a much shorter wavelength and much stronger interaction with atoms in a crystal compared with X-ray. LÄS MER
2. From Time-Averaged to Time-Resolved Crystallography: Studies on Superoxide Dismutase and Myoglobin
Sammanfattning : We have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. LÄS MER
3. Nanoplasmonic Enhancement of Photon-to-Electron Conversion in Functionalized Iron Oxide Photoanodes
Sammanfattning : The ever increasing energy demand of modern society clashes with the accelerating depletion of the fossil fuels from which most of this energy is taken today. Moreover, fossil fuels consumption poses a severe threat on the Earth’s environment and climate through global warming. LÄS MER
4. Electromagnetic Field Induced Out-of-Equilibrium Structural Dynamics in Protein Crystals: From Picoseconds to Milliseconds
Sammanfattning : Light-induced interactions in biomolecules are strongly varying over different model systems. Most amino acids and proteins absorb ultraviolet light, but only a few with specialised chromophores or fluorophores, are able to absorb light in the visible spectrum. LÄS MER
5. Friction stir welding of copper canisters for nuclear waste
Sammanfattning : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). LÄS MER
