Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure. Its properties include high strength and good conductivity of heat and electricity. The stacked form of graphene is graphite.
Rotational symmetry is shown to protect the quadratic dispersion of out-of-plane flexural vibrations in graphene and other two-dimensional materials against phonon–phonon interactions, making the bending rigidity of these materials non-divergent. The quadratic dispersion is then consistent with the propagation of sound in the graphene plane.
The preparation of atom-thick lattices with Å-scale pores is desirable for achieving ion selectivity and high ion flux. Here authors present a cm-scale membrane made of atom-thick graphene film hosting zero-dimensional pores spanning only a few Å, repaired using an in situ electrochemical strategy, yielding high Li+/Mg2+ separation performance.
Tuning the instabilities of 2D materials can control their wrinkling behavior for interesting physical properties, but still challenging. Here, the authors report a push-to-shear experimental approach to control the wrinkling patterns of monolayer 2D materials and measure their bending stiffness.

By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.
A large-angle twist between two bilayer graphene films makes a sensitive and broadband infrared–terahertz detector as a result of interlayer screening and a crystal field-induced bandgap.
A living catalyst transfer polymerization enables access to low dispersity polyphenylenes and ultimately to length-selective synthesis of graphene nanoribbons.
