      abstract     = {In-situ imaging of chemical reactions can provide valuable
                      insight into nanoparticle growth and structural evolution.
                      Hard X-ray imaging is an excellent tool for this purpose, as
                      it combines high spatial resolution with high penetration
                      depth, allowing for realistic reaction environments. While
                      far-field ptychography is a well-established method at
                      synchrotron radiation sources, its near-field analog has
                      received less attention. In this work we show that
                      near-field multi-slice ptychography is a competitive method
                      for high-resolution in-situ imaging by studying the
                      formation of gold nanocages via galvanic replacement. Our
                      work extends near-field X-ray ptychography to sub-50 nm
                      spatial resolution by using multilayer Laue lenses. These
                      high numerical aperture optics enable to distinguish sample
                      layers that are separated by less than 100 µm by
                      multi-slicing techniques.},
