A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

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

Imaging techniques permit the study of the molecular interactions that underlie health and
disease. Each imaging technique collects unique chemical information about the cellular …

Continual advancements in the development of synchrotron radiation sources have resulted
in X-ray based spectroscopic techniques capable of probing the electronic and structural …

The development and application of the free-electron X-ray laser (XFEL) to structure and
dynamics in biology since its inception in 2009 are reviewed. The research opportunities …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

Core-level spectra of 1s electrons of elements heavier than Ne show significant relativistic
effects. We combine advances in orbital-optimized density functional theory (OO-DFT) with …

We present a liquid flatjet system for solution phase soft-x-ray spectroscopy. The flatjet set-
up utilises the phenomenon of formation of stable liquid sheets upon collision of two …

The contested electronic structure of [Cu (CF3) 4] 1–is investigated with UV/visible/near IR
spectroscopy, Cu K-edge X-ray absorption spectroscopy, and 1s2p resonant inelastic X-ray …

Transition metals in inorganic systems and metalloproteins can occur in different oxidation
states, which makes them ideal redox-active catalysts. To gain a mechanistic understanding …
