Description
BL16 NOTOS bridges the gap between X-ray Absorption Spectroscopy (XAS) and X-ray Diffraction (XRD) by enabling sequential, quasi-simultaneous measurements on a single sample. This multimodal approach provides a comprehensive picture of material evolution: operando XAS offers element-specific sensitivity to monitor oxidation states and local coordination changes, while operando XRD provides direct evidence of long-range structural transformations, phase transitions, and lattice strains. Correlating these electronic and structural dynamics is vital for elucidating fundamental structure-function relationships and failure mechanisms across diverse scientific disciplines. This is particularly crucial in catalysis and energy materials research, where understanding complex electrochemical processes during operation is essential for improving performance and lifespan.
To facilitate these advanced studies, NOTOS features an extensive sample environment pool equipped with specialized multi-cell battery supports, high-temperature catalysis reactors, and real-time gas and liquid analysis systems.
Further enhancing its technical capabilities, the commissioning of the Kirkpatrick-Baez (KB) mirror system was successfully concluded in July 2026. This new micro-focus station delivers a stable, micro-focused beam, reaching spot sizes as small as 10 x 10 μm² (VxH) at the sample position. In the InCAEM (In Situ Correlative Facility for Advanced Energy Materials) framework, this instrument will open significant possibilities for correlative in-situ and operando experiments: researchers will study the identical sample area across NOTOS and the Scanning Transmission Electron Microscope in JEMCA, obtaining complementary information at multiple length scales without sample alteration.
