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 past two decades have seen rapid developments in short-pulse X-ray sources, which
have enabled the study of nuclear and electronic dynamics by ultrafast X-ray spectroscopies …

Utilization of renewable energies for catalytically generating value-added chemicals is
highly desirable in this era of rising energy demands and climate change impacts. Artificial …

Hard x-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential
technique for the characterisation of materials. The number of specialised photoelectron …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

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

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 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 …

Time-resolved photoemission with ultrafast pump and probe pulses is an emerging
technique with wide application potential. Real-time recording of nonequilibrium electronic …

The conversion of photon energy into other energetic forms in molecules is accompanied by
charge moving on ultrafast timescales. We directly observe the charge motion at a specific …
