      abstract     = {The ligand shell (LS) determines a number of
                      nanoparticles’ properties. Nanoparticles’ cores can be
                      accurately characterized; yet the structure of the LS, when
                      composed of mixture of molecules, can be described only
                      qualitatively (e.g., patchy, Janus, and random). Here we
                      show that quantitative description of the LS’ morphology
                      of monodisperse nanoparticles can be obtained using
                      small-angle neutron scattering (SANS), measured at multiple
                      contrasts, achieved by either ligand or solvent deuteration.
                      Three-dimensional models of the nanoparticles’ core and LS
                      are generated using an ab initio reconstruction method.
                      Characteristic length scales extracted from the models are
                      compared with simulations. We also characterize the
                      evolution of the LS upon thermal annealing, and investigate
                      the LS morphology of mixed-ligand copper and silver
                      nanoparticles as well as gold nanoparticles coated with
                      ternary mixtures. Our results suggest that SANS combined
                      with multiphase modeling is a versatile approach for the
                      characterization of nanoparticles’ LS.},
