TL;DR: Co coating of graphene oxide and graphene flakes onto jute fibers enhanced interfacial shear strength by ∼236% and tensilestrength by ∼96% more than untreated fibers by forming either bonding (GO) or mechanical interlocking (G) between fibers and graphene-based flakes.

TL;DR: Mechanical exfoliation is utilized to produce a two-dimensional form of a mineral franckeite and it is shown that the phase segregation of chemical species into discrete layers at the sub-nanometre scale facilitates franckeites' layered structure and basal cleavage down to a single unit cell thickness.

TL;DR: It is revealed that domain walls can become trapped between crystalline planes, and that they propagate by distinct jumps that match the lattice periodicity, which offers a means for probing experimentally the physics of topological defects in discrete lattices.

TL;DR: In this paper, the plane-wave density functional theory code CASTEP was used with the Tkatchenko-Scheffler van der Waals correction scheme and the generalized gradient approximation of Perdew, Burke, and Ernzerhof (GGA PBE) to calculate the binding energy of Au, Cr, and Al atoms on the armchair and zigzag edge binding sites of monolayer graphene, and at the high-symmetry adsorption sites of single layer, bilayer, and trilayer graphene.

TL;DR: In this paper, the authors performed a metrological characterization of the quantum Hall resistance in a 1'μm wide graphene Hall bar and showed that the longitudinal resistivity in the center of the ν=±2 quantum Hall plateaus vanishes within the measurement noise of 20'mΩ up to 2'μA.
