| Research Abstract |
Element-specific high-resolution coherent X-ray diffraction microscopy with energy-tunable X-ray focusing mirrors has been developed at SPring-8 that is the third-generation synchrotron radiation facility and has been applied to nano-meso structural analysis of functional metallic nanoparticles. 2 nm resolution, which is the world record of the spatial resolution of X-ray microscopy, has been achieved at the measurements of a Ag nanocube particle. Three-dimensional electron density mapping of a Au/ Ag nanobox particle has been visualized. In addition, large-field-of-view imaging has been also realized by extending to a scanning scheme.
