We investigate the origins of interesting physical properties in various kinds of materials, especially transition metal compounds, from crystallographic and nano-structural viewpoint by transmission electron microscopy and X-ray diffraction techniques. We also explore emergent materials by control of the crystal structures and nano-structures.
