Published at ACS Nano 2025, 19, 24, 21950–21961 Most data can be accessed with any program that reads csv and txt. FLUPS data needs the Surface explorer program from Ultrafast systems. FLUPS and TAS raw data need processing, but processed data is also given. TEM data needs an image processor like ImageJ. License: CC-BY The data has been obtained with the following acknowledgements: The TR-XAS XFEL experiments were performed at the BL3 (EH2) of SACLA with the approval of the Japan Synchrotron Radiation Research Institute (JASRI), proposal 2021B8047. The steady-state XAS experiments were performed at the CLÆSS beamline at ALBA Synchrotron with the collaboration of ALBA staff, proposal 2021095311. The facilities provided by the Center for Ultrafast Lasers (CLUR) of Universidad Complutense de Madrid (FLUPS) are gratefully acknowledged.
