  • 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.

  • A metastable palladium hydride is synthesized where the unique environment in the liquid cell, namely the limited quantity of Pd precursors and the continuous supply of H, resulted in the formation of the hcp phase.

  • In-situ cryo-electron microscopy in thin amorphous ice films and ice-dynamics simulations reveal polymorph-dependent growth kinetics of nanoscale ice crystals. Hetero-crystalline ice exhibits anisotropic growth: fast-growing facets are associated with low-density interfaces, driving tetrahedral ordering of interfacial H2O molecules and accelerating ice growth.
