TL;DR: In this article, it was shown that point defects in graphene (fluorine adatoms in concentrations gradually increasing to stoichiometric fluorographene CFxD1:0 and irradiation defects (vacancies) carry magnetic moments with spin 1.

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: The presence of free-standing, single-layer graphene is confirmed with directly interpretable atomic-resolution imaging combined with the spatially resolved study of both the pi --> pi* transition and the pi + sigma plasmon.

TL;DR: It is shown that strong photoluminescence can be induced in single-layer graphene using an oxygen plasma treatment, and the PL is spatially uniform across the flakes and connected to elastic scattering spectra distinctly different from those of gapless pristine graphene.

TL;DR: A new and highly reliable approach for making graphene membranes of a macroscopic size and their characterization by transmission electron microscopy is described and it is found that long graphene beams supported by only one side do not scroll or fold, in striking contrast to the current perception of graphene as a supple thin fabric.
