  • An atomic stencilling method based on the co-adsorption of iodide and 2-naphthalenethiol on gold is described, yielding more than 20 different types of nanoparticle with masked and painted regions and patchy particle morphologies not reported previously.

  • The realization and phonon imaging of nanoscale mechanical metamaterials has remained challenging. Here the authors resolve the phonon dynamics and band structures of five different self-assembled nanoparticle lattices, revealing the role of nanoscale colloidal interactions in modulating the lattice properties.

  • Chiroptically active pinwheel assemblies on substrates are formed by tetrahedral gold nanoparticles from the effective ‘compression’ of a perovskite-like, low-density phase, thereby enabling the manufacture of metastructured coatings with special chiroptical characteristics as identified by photon-induced near-field electron microscopy and chirality measures.

  • Voids are known to impact the properties of materials, but the nanovoids also present are less well understood than macroscopic voids. Here, the authors utilise 3D imaging and graph theory to study nanovoid formation and impact on material properties.

  • Interfacial fluctuations at the nanoscale, such as shape evolution of a growing crystal, are prohibitively difficult to study experimentally. Here, the authors are able to map the kinetic and thermodynamic parameters involved in shaping of nanoparticle supracrystals by directly imaging the fluctuating crystal surface by liquid-phase TEM, and analyzing it in the context of capillary wave theory.
