  • Understanding how hydrogen embrittles steels and developing the solutions are crucial for enabling the hydrogen economy. Here, the authors report a materials design strategy that can increase the hydrogen trapping capacity by creating carbon vacancies in metal carbide precipitates via microalloying.

  • In materials science, it is a well-accepted fact that metals are generally ductile, and ceramics are always brittle. Here, the authors observe high level of plasticity and excellent elasticity in perovskite oxide under compression and bending with diameter of 2.1 μm.

  • Pb/U ratios and trace element distributions within zircon grains are used to determine a rock's age and geological processes, but the degree of element immobility and diffusion is uncertain. Here, the authors use atom probe tomography to reveal sub-micron scale mechanisms of trace element mobility.

  • While light-driven water splitting offers a renewable means to produce fuel, the limited availability of high-performance materials inspires the search for new photocatalysts. Here, authors demonstrate two-dimensional NiPS3 to enhance semiconductor photocatalytic H2 evolution activities.

  • Small-scale metallic materials often suffer from a lack of tensile ductility. Here, the authors report an unusual room-temperature super-elongation in CoCrFeNi nanopillars from spatial and synergistic coordination of deformation twinning and dislocation slips due to chemical heterogeneities.

  • Nanocrystalline metals are ultra-strong because of the large fraction of material at the grain boundaries, but this also leads to instability under applied loads. Here, the authors deepen our understanding of this by linking stress-driven motion of grain boundaries to grain boundary chemistry.

  • The understanding of catalytic reactions at the atomic interface is vital; however, the characterization and mechanism studies of atomically dispersed catalysts remain challenging. Here, the authors demonstrate Cu–Sn surface alloys with isolated Sn atoms on a Cu host to achieve efficient CO2 to CO conversion.

  • Topological phenomena in ferroelectrics such as vortices are of interest as they may be useful for high-density storage applications, but similar phenomena have not been seen in antiferroelectrics, which possess antipolar dipole arrangements. Here, using electron microscopy, topological antivortices and faint vortices are seen in the prototypical antiferroelectric PbZrO3.

  • Direct writing of active defects is a much sought-after step towards scalable quantum technologies. Here, the authors show a flexible approach by transferring momentum from an ion beam to thin films pre-deposited onto diamond surfaces (using films of Si, Ge, Sn or Pb) or fiber cores (using Eu).
