Recent improvements in instrumentation and data analysis for soft X-ray spectro-microscopy and spectro-ptychography have made significant advances in spatial resolution and sensitivity. This presentation will give an overview of Scanning Transmission X-ray microscopy (STXM), examples of performance of current instrumentation, report on exciting advances taking place in soft X-ray spectro-ptychography, and outline opportunities for in situ and operando studies. Examples will be taken primarily from recent studies of energy materials, in particular automotive fuel cells. Results from recent studies of 3D chemical structure by spectro-tomography and spectro-ptycho-tomography will be presented.
