Nature Nanotechnology, Published online: 29 April 2024; doi:10.1038/s41565-024-01658-6An in situ phase-separation method at microscale level creates stretchable superelastic porous nanocomposite conductors, reduces conductive filler usage and enables strain-resilient wireless wearable and implantable bioelectronics.

Nature Nanotechnology, Published online: 29 April 2024; doi:10.1038/s41565-024-01666-6Toroidic phases and their phase transitions are notoriously hard to study in natural materials. Now, a direct-kagome spin ice provides access to two low-temperature toroidal phases, ferrotoroidicity and paratoroidicity, as well as to toroidic phase transitions.
