Liquid Delivery Systems for Time Resolved X-ray Spectroscopy — •Zhong Yin — Tohoku University, Sendai, Japan

Advancements in modern light sources have transformed the study of matter, offering unparalleled brilliance, coherence, and ultrashort pulses [1,2]. These innovations have significantly enhanced our ability to explore electronic properties that are fundamental to bonding and reactivity in real time.

Time-resolved X-ray spectroscopy, with its exceptional element, site, and orbital specificity, has emerged as a key tool for probing electronic structures.

However, studying chemically and biologically relevant processes in the liquid phase presents significant experimental challenges, requiring advanced experimental setups and innovative sample delivery systems [3,4].

In this talk, I will highlight recent results from table-top sources, such as high-harmonic generation (HHG) [5,6], and free-electron laser (FEL) facilities that enable time-resolved X-ray spectroscopy of biochemical systems in the liquid phase. These advancements are opening new avenues for investigating ultrafast molecular dynamics in their native environments with unprecedented time resolution.
