      abstract     = {Being able to observe the formation of multi-material
                      nanostructures in situ, simultaneously from a morphological
                      and crystallographic perspective, is a challenging task.
                      Yet, this is essential for the fabrication of nanomaterials
                      with well-controlled composition exposing the most active
                      crystallographic surfaces, as required for highly active
                      catalysts in energy applications. To demonstrate how X-ray
                      ptychography can be combined with scanning nanoprobe
                      diffraction to realize multimodal imaging, we study growing
                      Cu$_2$O nanocubes and their transformation into Au
                      nanocages. During the growth of nanocubes at a temperature
                      of 138 °C, we measure the crystal structure of an
                      individual nanoparticle and determine the presence of (100)
                      crystallographic facets at its surface. We subsequently
                      visualize the transformation of Cu$_2$O into Au nanocages by
                      galvanic replacement. The nanocubes interior homogeneously
                      dissolves while smaller Au particles grow on their surface
                      and later coalesce to form porous nanocages. We finally
                      determine the amount of radiation damage making use of the
                      quantitative phase images. We find that both the total
                      surface dose as well as the dose rate imparted by the X-ray
                      beam trigger additional deposition of Au onto the nanocages.
                      Our multimodal approach can benefit in-solution imaging of
                      multi-material nanostructures in many related fields.},
