Our unit provides research support by means of X-ray crystal structure analysis, electron microscopy, and elemental analysis. In addition to supporting on the individual method, we give multifaceted research support by combining these methods. To give analyses of the highest level quality to researchers, we always update our knowledge and make training in our skills. We make collaboration with researchers, not only we perform merely routine works, to achieve purposes of their research and to provide new insights on the research through discussion based on the results. We also challenge to develop unexplored measurement methods aiming at more advanced and sophisticated analysis.
