Liquid water

•Liquid water exhibits structural rearrangements on picosecond and femtosecond time-scales •How does the structure and dynamics of liquids confined to nanoscopic length-scales differ from the bulk?

Femtosecond x-ray absorption spectroscopy 

Use femtosecond laser to drive hydrogen bond network



Ultrafast soft x-ray pulses provide the necessary resolution to probe bonding dynamics



In order to perform measurements, nanofluidic cells (
