WHAT: World first (as far as we know) use of spectro-ptychography to study an electrochemical reaction in an in-situ flow electrochemical device. This is a detailed study of the morphological and chemical changes of Cu cubic electrocatalysts under CO2 reduction conditions by quantitative chemical mapping derived from in-situ soft X-ray spectro-ptychography. This initial demonstration of in-situ spectro-ptychography paves the way for more detailed in-situ studies of electrochemical materials and processes. The image represents the spectro-ptychography measurements of Cu cubic particles under in-situ electrochemical conditions. Image drawn by Chunyang Zhang
