  • Copper produced by laser additive manufacturing often faces challenges with either low strength or low conductivity. Here, the authors present a design strategy to introduce uniformly dispersed nanoprecipitates during solidification, enhancing the strength while maintaining high conductivity.

  • 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.

  • 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.

  • 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.

  • 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.
