Evidence of Free‐Bound Transitions in Warm Dense Matter and Their Impact on Equation‐of‐State Measurements

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is now routinely created and probed in laboratories around the world, providing unprecedented insights into conditions achieved in stellar atmospheres, planetary interiors, and inertial confinement fusion experiments.

The first decade of XFELs [PDF]

open access: yesNature Reviews Physics, 2020
Over the past decade, several X-ray free-electron laser (XFEL) facilities have been constructed and started operation worldwide. New, high-repetition XFELs are expected to open to users in the next 5 years.

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

open access: yesJournal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

open access: yesSmall, EarlyView.
LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,

THE EUROPEAN XFEL PROJECT

open access: yes, 2007
The European XFEL will be a free electron laser based on self amplified spontaneous emission in the X-ray regime. The FEL is driven by a superconducting 17.5 GeV linear accelerator, followed by 5 separate undulators both for SASE FEL radiation and incoherent radiation. Start of operation is foreseen for 2013.
