New generation of synchrotron sources have opened many new avenues of research with x-ray beams, several orders of magnitude brighter than those available previously. I will describe the use of coherent X-ray beams, e.g., X-ray photon correlation spectroscopy (XPCS) to study the relaxation dynamics of capillary waves on polymer films and Coherent X-ray Diffraction (CXD) to study internal strain distribution of zeolites. I will also review X-Ray reflectivity to probe the structure at the surface and interfaces of multilayer systems such as those in organic light emitting diode devices as well as the grazing incidence small angle x-ray scattering (GISAXS) for studying structures of films of different systems.
