Elucidating Chemical Bonding and Mechanism of Material Synthesis and Functionality Using Synchrotron X-ray Spectroscopy

 Materials research is advancing rapidly, leading to the development of numerous functional and structural materials such as organic-inorganic hybrid materials, oxide ion conductors, zeolite catalysts, and solid solution nano-alloys. To develop new and higher-performing materials, it is essential to understand the "synthesis mechanisms" for more freely controlling the arrangement of atoms and molecules, and the "functional mechanisms" that explain why these materials exhibit superior properties. To elucidate these mechanisms, it is necessary to not only identify the structural changes accompanying reactions but also understand the interactions between atoms, including changes in chemical bonding and electronic states. Therefore, I utilize synchrotron measurements and computational science to observe in situ the local structure of atoms and the chemical bonds that connect them during property evaluation and material synthesis process. This approach aims to uncover the mechanisms behind the manifestation of material functionalities.
