TL;DR: In this paper, the FLASH soft X-ray free-electron laser was used to reconstruct a coherent diffraction pattern from a nano-structured nonperiodic object, before destroying it at 60,000 K.
Journal ArticleDOI
Atomic inner-shell X-ray laser at 1.46 nanometres pumped by an X-ray free-electron laser
Nina Rohringer,Duncan P. Ryan,Richard A. London,Michael Purvis,Felicie Albert,James Dunn,John D. Bozek,Christoph Bostedt,Alexander Graf,Randal M. Hill,Stefan P. Hau-Riege,Jorge J. Rocca +11 more
TL;DR: The implementation of an X-ray laser in the kiloelectronvolt energy regime, based on atomic population inversion and driven by rapid K-shell photo-ionization using pulses from anX-ray free-electron laser is described, which provides greatly increased wavelength stability, monochromaticity and improved temporal coherence by comparison with present-day X- Ray free-Electron lasers.

TL;DR: The notion that X-ray flash imaging can be used to achieve high resolution, beyond radiation damage limits for biological samples is supported, and the technique is applied to monitor the dynamics of polystyrene spheres in intense free-electron-laser pulses.

Opto-acoustic thrombolysis

TL;DR: In this paper, a catheter-based device for generating an ultrasound excitation in biological tissue was proposed, which can be used for the treatment of stroke-related conditions in humans, particularly for dissolving thrombus or treating vaspasm.
Journal ArticleDOI
Dynamics of biological molecules irradiated by short x-ray pulses.
TL;DR: A continuum model of the physics that leads to damage when a small particle absorbs a large x-ray dose is presented, and the main processes are found to be ionization and Coulomb-force driven atomic motion.
