1. 1. Imaging Living Cells with an X-ray Laser

   Författare :Gijs van der Schot; Tomas Ekeberg; Janos Hajdu; Filipe Maia; Pierre Thibault; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive X-ray imaging; flash X-ray imaging; lensless imaging; single particle imaging; cyanobacteria; phasing; image classification; substrate-free sample delivery; X-ray free-electron laser; XFEL; FEL; CDXI; CDI; CXI; FXI; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

   Sammanfattning : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. LÄS MER

3. 2. Interaction of Ultrashort X-ray Pulses with Material

   Författare :Magnus Bergh; Janos Hajdu; Andrea Cavalleri; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free-electron laser; dense plasma; X-ray; radiation damage; laser physics; nano-plasma; Molecular Dynamics; Molecular biophysics; Molekylär biofysik;

   Sammanfattning : Radiation damage limits the resolution in imaging experiments. Damage is caused by energy deposited into the sample during exposure. Ultrashort and extremely bright X-ray pulses from free-electron lasers (FELs) offer the possibility to outrun key damage processes, and temporarily improve radiation tolerance. LÄS MER
