Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01884-2An interface modification strategy has been developed to uniformly distribute high-density sub-10 nm coherent MgO particles in an Al matrix, resulting in high strength and creep resistance at temperatures up to 500 °C.

Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01883-3The molten structure of plutonium oxide—a component of mixed oxide nuclear fuels—is measured, showing some degree of covalent bonding. Its atomic structure is similar to that of cerium oxide, which could be a non-radioactive structural surrogate.

Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01893-1Adding homogeneously dispersed oxide nanoparticles to aluminium pushes its high-temperature strength up to 500 °C.

Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01891-3In a multi-principal-element VCoNi alloy, premature necking during Lüders banding has been harnessed to produce rapid dislocation multiplication, leading to both forest hardening and hardening induced by regions of local chemical order. The result is ductility of 20% and...

Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01886-0Electrode arrays for neurological diagnosis and treatment carry a risk of nerve injury. Nerve cuffs with tiny voltage-controlled shape-reconfigurable electrode arrays have been reported, allowing active wrapping around delicate nerves.
