Quantitative 3D real-space analysis of Laves phase supraparticles [PDF]

open access: yesNature Communications, 2021
3D real-space analysis of thick nanoparticle crystals is non-trivial. Here, the authors demonstrate the structural analysis of a bulk-like Laves phase by imaging an off-stoichiometric binary mixture of hard-sphere-like nanoparticles in spherical ...
