  • Atomic structural changes in nanocrystals are still poorly understood. Here, the authors introduce time-resolved Brownian tomography to directly detect 3D atomic changes in Pt nanocrystals during oxidative etching and reveal disorder at sizes of ≈1 nm.

  • Colloidal nanocrystals find applications from electronics to catalysis and biological sensors, but their complex surface structures are challenging to explore. Here, the authors use graphene liquid cell transmission electron microscopy to show that solubilized platinum crystals of less than 3 nm in size have individual, ordered cores surrounded by mobile surface atoms.
