      abstract     = {Supercrystalline nanocomposites (SCNCs) are nanostructured
                      hybrid materials with a variety of unique functional
                      properties. Given their periodically arranged building
                      blocks, they also offer interesting parallels with
                      crystalline materials. They can be processed in multiple
                      forms and at different scales, and cross-linking their
                      organic ligands via heat treatment leads to a boost of their
                      mechanical properties. This study shows, via X-ray and in
                      situ scanning transmission electron microscopy (STEM)
                      analyses, how each of these processing steps plays a
                      distinct role in the generation, migration, interaction, and
                      healing of supercrystalline defects. Pressing of SCNCs into
                      bulk pellets leads to a distortion of the otherwise fcc
                      superlattice, while emulsion-templated self-assembly yields
                      supraparticles (SPs) with stacking faults and size-dependent
                      symmetries. Heat treatment at the same temperatures as those
                      applied for the organic cross-linking has significant
                      effects on planar defects. Stacking faults migrate and get
                      healed, as also confirmed via molecular dynamics
                      simulations, and intersupercrystalline “grain”
                      boundaries migrate via anisotropic motion of disconnections.
                      These rearrangements of defects at the supercrystalline
                      scale (tens of nanometers) in nanocomposites with high
                      mechanical properties (compressive strength of 100–500
                      MPa) provide insights into the formation and evolution of
                      ordered assemblies of functionalized nanoparticles.},
