”Function visualization of materials through coalition between advanced synchrotron radiation measurement and informatics”

Many practical materials are heterogeneous complex systems with hierarchical structures from nanometer to micrometer scale. It is therefore important to understand correlation between the fine structures and the function at nano-meso scale to create new functional materials. Synchrotron radiation microscopy/spectroscopy can provide multimodal visualization of bulk materials. Especially, coherent X-ray diffraction imaging is a promising method for visualizing the structures inside bulk materials at the nanoscale, which provides the huge amount of structural and chemical data in real 3D space. Recent machine learning and data-mining techniques can help the discovery and comprehension of new materials and phenomena. Our mission is the development of next-generation synchrotron radiation microscopy /spectroscopy methods using novel X-ray optics. Finally, we will create the platform to visualize the function of practical materials using informatics.
