| Open AccessVision-controlled jetting for composite systems and robots
We have developed an automated and high-throughput, three-dimensional, vision-controlled inkjet deposition process that enables the high-resolution, contactless printing of a range of materials with varying elastic moduli to create complex structures and robots.

Toughening mechanisms of the elytra of the diabolical ironclad beetle
A jigsaw-style configuration of interlocking structures identified in the elytra of the remarkably tough diabolical ironclad beetle, Phloeodes diabolicus, is used to inspire crush-resistant multilayer composites for engineering joints.

Enzymatic mineralization generates ultrastiff and tough hydrogels with tunable mechanics
Synthetic hydrogels are here created by enzyme-induced mineralization of hydrogel networks, yielding materials that are tough yet impressively stiff, with calcium phosphate particles distributed homogeneously throughout the network.

Combinatorial design of textured mechanical metamaterials
Lattices of cubic building blocks that deform anisotropically and that are designed to fit together like a three-dimensional jigsaw puzzle are 3D printed to create aperiodic, frustration-free, mechanical metamaterials; these metamaterials act as programmable shape-shifters and are able to perform pattern analysis.

Controlled fragmentation of multimaterial fibres and films via polymer cold-drawing
Cold-drawing of multimaterial fibres consisting of a brittle core embedded in a ductile polymer cladding results in controllable fragmentation of the core to produce uniformly sized rods parallel to the drawing direction for cylindrical geometries and narrow, parallel strips perpendicular to the drawing direction for flat geometries.

Processing and properties of magnesium containing a dense uniform dispersion of nanoparticles
Magnesium is light but not very strong; here the addition of silicon carbide nanoparticles uniformly dispersed to 14 per cent by volume, achieved through a nanoparticle self-stabilization mechanism in a molten metal alloy, yields improved strength, stiffness, plasticity and high-temperature stability.
