TL;DR: The layers are found to comprise defect-free graphene areas with sizes of a few nanometers interspersed with defect areas dominated by clustered pentagons and heptagons, which makes all carbon atoms in these defective areas undetectable by spectroscopic techniques.

TL;DR: It is shown that reducing molecular friction by using highly crystalline graphite and mild oxidizing conditions is the key to high quality graphene.

TL;DR: It is shown that TMDs can be doped by filling the vacancies created by the electron beam with impurity atoms, and this results shed light on the radiation response of a system with reduced dimensionality, but also suggest new ways for engineering the electronic structure of T MDs.

TL;DR: This work creates an sp2-hybridized one-atom-thick flat carbon membrane with a random arrangement of polygons, including four-membered carbon rings that possess a band gap, which may open new possibilities for engineering graphene-based electronic devices.

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.
