Membranes
Abraham, Vasu, Williams, et al., Nat. Nanotechnol. 12, 546 (2017). Physically confined GO laminates; interlayer d tuned ~9.8 Å to 6.4 Å. Ion permeation thermally activated; water less affected. Demo: 97% NaCl rejection in that confined stack. Continuation of Nair 2012, not a municipal plant.
