Brief description of the work:

We are currently successfully carrying on some liquid-phase pump-probe experiments where we have implemented ultrafast x-ray absorption to trace the condensed phase dynamics (picosecond time scale). We are using laser-pump synchrotron-x-ray-probe scheme (we’re running our experiments at the ALS, Berkeley) with the temporal resolution of ca. 75 ps (cross-correlation) in order to record transient XANES and EXAFS signals in various chemical diluted systems flown in a opened jet (helium atmosphere)
