1. 1. Simulations of Biomolecular Fragmentation and Diffraction with Ultrafast X-ray Lasers

   Författare :Christofer Östlin; Carl Caleman; Nicusor Timneanu; Helmut Grubmüller; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; X-ray imaging; Single particle imaging; Computer simulation; Radiation damage; Molecular dynamics; Diffraction theory; Coulomb explosion; Sample heterogeneity; Diffractive noise; XFEL; SPI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Sammanfattning : Studies of biomolecules have recently seen substantial developments. New X-ray lasers allow for high-resolution imaging of protein crystals too small for conventional X-ray crystallography. Even structures of single particles have been determined at lower resolutions with these new sources. LÄS MER

3. 2. Simulations of ultrafast photon-matter interactions for molecular imaging with X-ray lasers

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; molecular dynamics; radiation damage; plasma simulations; density functional theory¸ coherent diffractive imaging; protein structure; X-ray crystallography; single particle imaging;

   Sammanfattning : Biological structure determination has had new avenues of investigation opened due to the introduction of X-ray free-electron lasers (XFELs). These X-ray lasers provide an extreme amount of photons on ultrafast timescales used to probe matter, and in particular biomolecules. LÄS MER
