TL;DR: Graphene nanosheets may potentially serve as an encapsulating material for delivery of such microorganisms and as an effective photothermal agent for inactivation of the graphene-wrapped microorganisms.

TL;DR: This work reports the fabrication of narrow and smooth capillaries through van der Waals assembly, with atomically flat sheets at the top and bottom separated by spacers made of two-dimensional crystals with a precisely controlled number of layers, using graphene and its multilayers as archetypalTwo-dimensional materials to demonstrate this technology.

TL;DR: Capacitance measurements reveal a low dielectric constant for atomically thin layers of water next to solid surfaces and reveal the presence of an interfacial layer with vanishingly small polarization such that its out-of-plane ε is only ~2, while the electrically dead layer is found to be two to three molecules thick.

TL;DR: In this article, a photocatalytic reduction of the graphene oxide sheets by the TiO2 nanoparticles in ethanol was shown to increase the graphitized sp2 structure over the disorders in the reduced graphene oxides.

TL;DR: This work reports ion transport through ultimately narrow slits that are fabricated by effectively removing a single atomic plane from a bulk crystal, and finds that ions with hydrated diameters larger than the slit size can still permeate through, albeit with reduced mobility.
