Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

The metal centres in metalloenzymes and molecular catalysts are responsible for the
rearrangement of atoms and electrons during complex chemical reactions, and they enable …

An overview of both experimental and theoretical results in the field of resonant scattering of
tunable soft and hard x-ray radiation is presented, with a main focus on the closely related …

In the field of beam physics, two frontier topics have taken center stage due to their potential
to enable new approaches to discovery in a wide swath of science. These areas are …

We report the measurement of impulsive stimulated x-ray Raman scattering in neutral liquid
water. An attosecond pulse drives the excitations of an electronic wavepacket in water …

Oscillators are at the heart of optical lasers, providing stable, transform-limited pulses. Until
now, laser oscillators have been available only in the infrared to visible and near-ultraviolet …

When materials are exposed to X-ray pulses with sufficiently high intensity, various
nonlinear effects can occur. The most fundamental one consists of stimulated electronic …

X-ray free-electron lasers (XFELs) provide intense pulses that can generate stimulated X-ray
emission, a phenomenon that has been observed and studied in materials ranging from …

K β x-ray emission spectroscopy is a powerful probe for electronic structure analysis of 3 d
transition metal systems and their ultrafast dynamics. Selectively enhancing specific spectral …

After a short introduction highlighting the potentialities of metal–organic frameworks (MOFs)
and the power of X-ray absorption spectroscopies (XAS), a list of selected examples follows …
