Thanks to the Fédération de Spectroscopies de Photoémission for the kind invitation to give an online webinar on our recent work in time-resolved X-ray photoelectron spectroscopy today. Great discussion and questions — looking forward to future exchanges, collaborations, and my next visit to SOLEIL.
