in-situ measurement at BL40B2, SPring-8

Abstract

In a significant collaborative effort, doctoral researchers Chunlin Pei and Yifan Bai from the research groups of Prof. Uchimoto (collaborating institution) and Prof. Gao successfully completed a series of in-situ Grazing-Incidence Small-Angle X-ray Scattering (GISAXS) and Grazing-Incidence Wide-Angle X-ray Scattering (GIWAXS) experiments at the BL40B2 beamline of SPring-8, Japan’s premier synchrotron radiation facility, from November 27 to 30, 2024. The experiments focused on probing dynamic structural evolution in advanced functional ionomer thin films under controlled humidity conditions, leveraging the ultra-bright X-rays and high-resolution detectors at SPring-8 to capture real-time nanoscale and atomic-scale changes. These techniques are critical for understanding elelctrochmical interfacial phenomena, phase transitions, and morphology dynamics in materials such as polyemr electrolyte fuel cells, thin-film catalysts, or energy storage systems—though specific applications remain under wraps pending publication. This groundbreaking work was supported by the National Natural Science Foundation of China (NSFC Grant No. 22302094) and the Natural Science Foundation of Jiangsu Province (Grant No. BK20210346), underscoring its alignment with national and regional priorities in cutting-edge materials science.
