Reaction dynamics studied via femtosecond X-ray liquidography at X-ray free-electron lasers.X-ray free-electron lasers (XFELs) provide femtosecond X-ray pulses suitable for pump-probe time-resolved studies with a femtosecond time resolution.  Since the advent of the first XFEL in 2009, recent years have witnessed a great number of applications with various pump-probe techniques at XFELs.  Here, we classify various chemical and biological molecular systems studied via femtosecond TRXL (fs-TRXL) at XFELs, depending on the focus of the studied process, into
