TL;DR: In this paper, the authors demonstrate a cleaning process that verifiably removes the contamination on the device structure and allows the intrinsic chemical responses of the graphene monolayer to be measured.

TL;DR: In this article, DNA translocations through nanopores created in graphene membranes are reported. But, the nanopores are made from 1-5 nm thick graphene membranes with electron-beam sculpted nanopores from 5 to 10 nm in diameter.

TL;DR: In this article, the surface area of a graphene oxide membrane is shown to have a surface area above about 200 μm and exhibit electrical conductivity in excess of about 200 S/m.

TL;DR: In this paper, the authors report broadband visible photoluminescence from solid graphene oxide, and modifications of the emission spectrum by progressive chemical reduction, suggesting a gapping of the two-dimensional electronic system by removal of π-electrons.

TL;DR: In this article, an atmospheric pressure chemical vapor deposition (CVD) method was developed for the growth of large-area graphene on catalytic metal substrates, which is potentially more cost-effective and compatible with industrial production than approaches based on synthesis under high vacuum, and the results showed that field effect transistors fabricated from CVD graphene made with the optimized process had room temperature hole mobilities that are a factor of 2−5 larger than those measured for samples grown on as-purchased Cu foil with larger methane concentration.
