Nature Nanotechnology, Published online: 09 May 2024; doi:10.1038/s41565-024-01669-3A flow-through redox-neutral electrochemical reactor–electrodialysis system has been developed to recover water, alkali and acids from hypersaline wastewaters. This accelerates a shift in ‘zero-discharge’ technology from energy-intensive steam-driven to energy-efficient...

Nature Nanotechnology, Published online: 06 May 2024; doi:10.1038/s41565-024-01655-9The ability to vaccinate against multiple related pathogens is a significant advantage. Here, the authors report on quartets of linked receptor-binding domains attached to designed nanocages using SpyTag/SpyCatcher links, demonstrating effective vaccination against similar...

Nature Nanotechnology, Published online: 06 May 2024; doi:10.1038/s41565-024-01659-5By manipulating the glass transition of the electrolyte, nanometre-resolution electrochemical ion implantation doping can be achieved in various polymeric semiconductors.

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.

Nature Nanotechnology, Published online: 29 April 2024; doi:10.1038/s41565-024-01662-wAn on-chip tunable laser operates by harnessing nanomechanical resonances at the radio frequency, achieving ultralow tuning power consumption.
