      abstract     = {Nanocrystal self-assembly into supercrystals provides a
                      versatile platform for creating novel materials and devices
                      with tailored properties. While common self-assembly
                      strategies imply the use of purified nanoparticles after
                      synthesis, conversion of chemical precursors directly into
                      nanocrystals and then supercrystals in simple procedures has
                      been rarely reported. Here, the nucleation and growth of
                      CuPd icosahedra and their consecutive assembly into large
                      closed-packed face-centered cubic (fcc) supercrystals are
                      studied. To this end, the study simultaneously and in situ
                      measures X-ray total scattering with pair distribution
                      function analysis (TS-PDF) and small-angle X-ray scattering
                      (SAXS). It is found that the supercrystals' formation is
                      preceded by an intermediate dense phase of nanocrystals
                      displaying short-range order (SRO). It is further shown that
                      the organization of oleic acid/oleylamine surfactants into
                      lamellar structures likely drives the emergence of the SRO
                      phase and later of the supercrystals by reducing the volume
                      accessible to particle diffusion. The supercrystals'
                      formation as well as their disassembly are triggered by
                      temperature. The study demonstrates that ordering of solvent
                      molecules can be crucial in the direct synthesis of
                      supercrystals. The study also provides a general approach to
                      investigate novel preparation routes of supercrystals in
                      situ and across several length scales via X-ray scattering.},
