Cover Picture: A Regularly Channeled Lamellar Membrane for Unparalleled Water and Organics Permeation (Angew. Chem. Int. Ed. 23/2018)

Lamellar membranes with ordered interlayer channels show exceptional permeation properties for separation processes. In their Communication on page 6814 ff., W. Guo, S.-Z. Qiao et al. demonstrate the direct self-stacking of rigid MXene nanosheets to form highly regular and straight 2 nm channels. The membranes exhibit unparalleled permeation of liquids from water to organics and achieve precise molecular rejection of targeted dyes. Significantly, the equation for the molecular transfer rate in confined channels is also established.
