  • Quasicrystals are typically stiff and hard, but also brittle in bulk form at room temperature. Here, authors observe ductile behaviour in quasicrystalline pillars of submicron diameter and provide evidence for dislocation-based plasticity at intermediate length scales and room temperature as an explanation.

  • Inkfree multi-material printing is a common challenge in 3D printing. Here, the authors introduce electrohydrodynamic redox printing, a method that enables the deposition of multiple metals and their alloys with nanoscale resolution and thus the synthesis of materials with locally tuned properties.

  • Silicon is thought to be brittle, which limits its mechanical application in devices. Here, the authors lithographically fabricate silicon and show its superior surface quality leads to near ideal strength and micron-scale plasticity.

  • In this paper, we introduce a new paradigm to design scalable disordered metamaterials. We show that the localized crystallization of a semiconductor at a metal/semiconductor interface can be used as design parameter to control light interaction in such a disordered system. Here, such thermally induced crystallization, also called metal-induced crystallization, generates new zero-index states corresponding to a hybrid resonant mode emerging from selective coupling of light to the angstrom-sized crystalline shell of the semiconductor.
