The marvels of moiré materials

Nature Reviews Materials, Published online: 03 March 2021; doi:10.1038/s41578-021-00284-1Moiré systems formed by 2D atomic layers have widely tunable electrical and optical properties and host exotic, strongly correlated and topological phenomena, including superconductivity, correlated insulator states and orbital magnetism. In this Viewpoint, researchers...

Autonomous materials systems from active liquid crystals

Nature Reviews Materials, Published online: 25 February 2021; doi:10.1038/s41578-020-00272-xActive liquid crystals are a particular type of active materials in which an inherent structural anisotropy leads to long-range order and topological defects. This Review discusses natural and synthetic active liquid crystals, and explores their autonomous behaviour...
