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 optical transparency of any two-dimensional system with a symmetric electronic spectrum is governed by the fine structure constant and suggest a simple formula that relates a quasiparticle spectrum to an optical absorption of such a system.

TL;DR: High magnetic field scanning tunneling microscopy and Landau level spectroscopy of twisted graphene layers grown by chemical vapor deposition observe an unexpected electron-hole asymmetry which is substantially larger than the asymmetry in either single or untwayer graphene.

TL;DR: In this article, the authors report barrier properties of multilayer graphitic films made by gentle chemical reduction of graphene oxide laminates with hydroiodic and ascorbic acids.

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.
