TL;DR: The existence of a bandgap opening in graphene is demonstrated, induced by the patterned adsorption of atomic hydrogen onto the Moiré superlattice positions of graphene grown on an Ir(111) substrate.

TL;DR: A dual path mechanism in the thermal reduction of graphene oxide driven by the oxygen coverage is identified: at low surface density, the O atoms adsorbed as epoxy groups evolve as O(2) leaving the C network unmodified leaving theC network un modified.

TL;DR: It is shown that residual contaminants in purified single-wall carbon nanotube bundles may be responsible for the reported sensitivity of the electronic and transport properties to oxygen, and a strong sensitivity to NO(2, SO(2), and NH(3) is observed, confirming the possible application of single- wall nanotubes as powerful sensors capable of measuring environmentally significant levels of toxic gases.

TL;DR: These findings demonstrate that oxygen intercalation is an efficient method for fully decoupling an extended layer of graphene from a metal substrate, such as Ir(111), and pave the way for the fundamental research on graphene.

TL;DR: By combining high-resolution photoelectron spectroscopy and ab initio calculations, this article showed that carbon nanoislands formed during the growth of a long-range ordered graphene layer on Ir(111) assume a peculiar domelike shape.
