abstract = {With the ever-expanding functional applications of
supercrystalline nanocomposites (a relatively new category
of materials consisting of organically functionalized
nanoparticles arranged into periodic structures), it becomes
necessary to ensure their structural stability and
understand their deformation and failure mechanisms.
Inducing the cross-linking of the functionalizing organic
ligands, for instance, leads to a remarkable enhancement of
the nanocomposites’ mechanical properties. It is however
still unknown how the cross-linked organic phase
redistributes applied loads, how the supercrystalline
lattice accommodates the imposed deformations, and thus in
general what phenomena govern the overall material’s
mechanical response. This work elucidates these aspects for
cross-linked supercrystalline nanocomposites through an in
situ small- and wide-angle X-ray scattering study combined
with uniaxial pressing. Because of this loading condition,
it emerges that the cross-linked ligands effectively carry
and distribute loads homogeneously throughout the
nanocomposites, while the superlattice deforms via rotation,
slip, and local defects generation.},
