| Outline of Final Research Achievements |
In this project, a new time resolved x-ray absorption fine structure (XAFS) method was tried to be established. XAFS is an important method to understand chemical states on electrodes of batteries or fuel cells. However, chemical reactions of the electrodes cannot be observed with XAFS since the time resolution of XAFS is much slower than the reaction time scales of the electrode chemical reaction. In this new system, a time stamp is decided at the same time each fluorescence x-ray photon from a sample is detected. It was confirmed that the principle of this measurement was plausible.
