TL;DR: This work investigates permeation through micrometer-thick laminates prepared by means of vacuum filtration of graphene oxide suspensions, which reveal that the GO membrane can attract a high concentration of small ions into the membrane, which may explain the fast ion transport.

TL;DR: Transport and mass spectroscopy measurements are reported which establish that monolayers of graphene and hexagonal boron nitride are highly permeable to thermal protons under ambient conditions, whereas no proton transport is detected for thicker crystals such as monolayer molybdenum disulphide, bilayer graphene or multilayer hBN.

TL;DR: High-resolution electron microscopy imaging of water locked between two graphene sheets is reported, an archetypal example of hydrophobic confinement, and shows that the nanoconfined water at room temperature forms ‘square ice’—a phase having symmetry qualitatively different from the conventional tetrahedral geometry of hydrogen bonding between water molecules.

TL;DR: In this article, the authors report efficient and fast filtration of organic solutions through Graphene oxide (GO) laminates containing smooth two-dimensional (2D) capillaries made from large (10 to 20) flakes.

TL;DR: This work reports the fabrication of narrow and smooth capillaries through van der Waals assembly, with atomically flat sheets at the top and bottom separated by spacers made of two-dimensional crystals with a precisely controlled number of layers, using graphene and its multilayers as archetypalTwo-dimensional materials to demonstrate this technology.
