  • Membranes with fast and selective separation of ions are universally desired in many applications. Here, authors inspired by biological potassium ion channels have constructed an MXene based biomimetic ion channel membrane to achieve efficient separation of ions.

  • 'Covalent modification, while tuning the channel size and functionality, disrupts the structure of 2D membranes. Here the authors demonstrate controllable and selective mass transport, via nondisruptive non-covalent modification of sub-1-nm MXene channels, enabled by nanoconfinement effect.

  • Top-down exfoliation is one of the most promising approaches for the scalable production of 2D materials, but the current techniques are limited by low yield of monolayers. Here, the authors report the exfoliation of graphene and other layered materials via viscous-polymer-assisted ball-milling, leading to a production of graphene products with monolayer percentage up to 97.9% at a yield of 78.3%.
