Conspectus Water splitting is intensively studied for sustainable and effective energy
storage in green/alternative energy harvesting–storage–release cycles. In this work, we …

The non-monochromatic beamline BL1 at the FLASH free-electron laser facility at DESY was
upgraded with new transport and focusing optics, and a new permanent end-station, CAMP …

We summarize exploratory work on multigrain crystallography. The experimental
arrangement comprises a monochromatic beam, a fully illuminated sample with up to …

We present a flexible and compact experimental setup that combines an in vacuum liquid jet
with an x-ray emission spectrometer to enable static and femtosecond time-resolved …

A novel sample holder for soft x-ray absorption spectroscopy of liquids in transmission mode
based on sample cells with x-ray transparent silicon nitride membranes is introduced. The …

Serial femtosecond crystallography (SFX) using X-ray free-electron laser (FEL) sources has
the potential to determine the structures of macromolecules beyond the limitation of radiation …

We report on oxygen K-edge soft x-ray emission spectroscopy from a liquid water jet at the
Linac Coherent Light Source. We observe significant changes in the spectral content when …

In the current work, X-ray emission spectra of aqueous solutions of different inorganic salts
within the Hofmeister series are presented. The results reflect the direct interaction of the …

It is expected that free-electron laser (FEL) radiation with its unique properties will allow real-
time tracking of structural changes during chemical reactions. The methods suggested being …

The chapter will focus on fundamental aspects and methodological challenges of X-ray free
electron laser research and recent developments in the related field of ultrafast X-ray …
