Departments of Marine Engineering, Material Science and Engineering,Texas A&M University, College Station TX, 77843 USA(Dated: July 9, 2014)Twisted graphene layers produce a moir´e pattern (MP) structure with a predetermined wavelengthfor given twist angle. However, predicting the membrane corrugation amplitude for any angle otherthan pure AB-stacked or AA-stacked graphene is impossible using ﬁrst-principles density functionaltheory (DFT) due to the large supercell. Here, within elasticity…

Unconventional superconductivity in bilayer graphene has been reported for twist angles θ near the first magic angle and charged electrostatically with holes near half filling of the lower flat
Complete steric exclusion of ions and proton transport through confined monolayer water
Water moves through capillaries made by effectively extracting one atomic plane from bulk crystals, which leaves a two-dimensional slit of a few angstroms in height, whereas no permeation could be detected even for such small ions as Na+ and Cl−.
