      abstract     = {Tuning the energy of an x-ray probe to an absorption line
                      or edge can provide material-specific measurements that are
                      particularly useful for interfaces. Simulated hard x-ray
                      images above the Fe K-edge are presented to examine ion
                      diffusion across an interface between Fe$_2$O$_3$ and
                      SiO$_2$ aerogel foam materials. The simulations demonstrate
                      the feasibility of such a technique for measurements of
                      density scale lengths near the interface with submicron
                      spatial resolution. A proof-of-principle experiment is
                      designed and performed at the Linac coherent light source
                      facility. Preliminary data show the change of the interface
                      after shock compression and heating with simultaneous
                      fluorescence spectra for temperature determination. The
                      results provide the first demonstration of using x-ray
                      imaging at an absorption edge as a diagnostic to detect
                      ultrafast phenomena for interface physics in
                      high-energy-density systems.},
