  • Advancing electron tomography to atomic resolution is a powerful and challenging process. Here, the authors demonstrate atomic resolution electron tomography on silver-gold core-shell nanoclusters grown in superfluid helium nanodroplets, revealing their three-dimensional morphology and composition.

  • Atomic-scale spinodal decomposition enabled diffusion was observed within ordered nanoprecipitates that have structural imperfections, resulting from dynamic interaction of Gibbs energy, activation energy of atomic jumps and phase ordering in multicomponent alloys.

  • Iodide based energy storage is a potential candidate to improve performance of hybrid supercapacitors and batteries. Here, the authors revisit the previous understanding and show that electrochemical oxidation of iodide results in solid iodine deposits stabilized by the confinement of nanoporous carbons.

  • Imaging the photonic local density of states of plasmonic nanoparticles remains extremely challenging. Here, the authors introduce a tomography scheme based on electron microscopy that allows retrieval of the three-dimensional local density of states with nanometre spatial and sub-eV energy resolution.

  • Single atom detection in nanoporous materials is challenging due to their sensitivity to electron irradiation. Here, the three-dimensional atomic occupancy of natural beryl is quantitatively analysed using high-angle annular dark-field imaging in a scanning transmission electron microscope and statistical analysis.

  • Hydrogen–metal surface interactions play an important role in energy technologies and metal corrosion, but a thorough understanding of these interactions at the nanoscale remains elusive due to detection limits and the volatility of pure hydrogen. Here, the authors use transmission electron microscopy to show that hydrogen adsorbs directly at the (0001) surfaces of hexagonal helium bubbles within neutron irradiated beryllium.
