Surface x-ray photon correlation spectroscopy (XPCS) is a powerful tool to study slow dynamics at small length scales. After a brief introduction to (surface) XPCS technique and beamline 8ID/XOR of the Advanced Photon Source, the focus of the talk will be the dynamics of liquid surfaces as revealed by XPCS. It will concentrate on thin liquid films in a partial wetting condition. Coherent x-rays were used to investigate structural and dynamical properties. Current capabilities of XPCS will be demonstrated using two brief examples at the end of this presentation.
