Their local physicochemical properties are quite different from those of bulk water and hard to probe experimentally.

Transient distributions of the conduction band electrons show an almost thermalized, low-energy part and a high-energy tail [...] OpenAccess: PDF PDF (PDFA); 2017-06-3017:57 [PUBDB-2017-06524] Journal Article et al Pulse Duration of Seeded Free-Electron Lasers Physical review / X 7(2), 021043 (2017) [10.1103/PhysRevX.7.021043]   The pulse duration, and, more generally, the temporal intensity profile of free-electron laser (FEL) pulses, is of utmost importance for exploring the new perspectives offered by FELs; it is a nontrivial experimental parameter that needs to be characterized. We measured the pulse shape of an extremeultraviolet externally seeded FEL operating in high-gain harmonic generation mode.

This process was observed within poly-crystalline diamond with a time-resolved experiment using ultrashort soft x-ray pulses of duration 52.5 fs and cross correlated by an optical pulse of duration 32.8 fs [...] Restricted: PDF PDF (PDFA); 2017-06-1213:43 [PUBDB-2017-04727] Journal Article Santra, R. Attosecond x-ray scattering from a particle-hole wave packet Physical review / A 95(6), 062107 (2017) [10.1103/PhysRevA.95.062107]   We investigate the imaging of electron wave-packet dynamics by measuring the pattern of inelastically scattered photons. For this purpose, we develop a theory of time-resolved Compton scattering [...] OpenAccess: PDF PDF (PDFA); 2017-06-0114:22 [PUBDB-2017-04151] Journal Article et al Femtosecond response of polyatomic molecules to ultra-intense hard X-rays Nature 546(7656), 129 - 132 (2017) [10.1038/nature22373]   X-ray free-electron lasers enable the investigation of the structure and dynamics of diverse systems, including atoms, molecules, nanocrystals and single bioparticles, under extreme conditions1, 2, 3, 4, 5, 6, 7. Many imaging applications that target biological systems and complex materials use hard X-ray pulses with extremely high peak intensities (exceeding 1020 watts per square centimetre)3, 5.
