  • Accurate characterization of emerging quantum sensors requires an imaging technique that does not depend on defect-specific optical readout. Here, using a NV center in diamond, the authors detect and map boron vacancy defects in hBN via spin cross-relaxation, enabling quantitative nanoscale imaging and spectroscopy without detecting hBN emission.

  • Free-standing graphene is inherently crumpled in the out-of-plane direction due to dynamic flexural phonons and static wrinkling. Here, the authors use optical interferometry as a delicate probe to investigate the consequences of this crumpling on the effective mechanical constants of graphene.

  • Proton transfer across graphene is associated with large computed energy barriers and is thought to be generally unfavourable. Here, the authors observe aqueous proton transfer through graphene subjected to pH cycling, suggesting that it is due to transfer through rare, naturally occurring atomic defects.

  • An improved industrial manufacturability has been achieved for a hybrid water-treatment membrane that exhibits high water permeance, prolonged high salt and dye rejection under cross-flow conditions and better resistance to chlorine treatment.
