TL;DR: Foot-long continuous single-crystal-like monolayer graphene films were fabricated on polycrystalline substrates by evolutionary selection growth, which resembles the Czochralski process in 2D geometry and could be readily adopted for the synthesis of other 2D materials and heterostructures.

TL;DR: In this article, a change in the surface roughness is sufficient enough to create super-hydrophobic surfaces of polytetrafluoroethylene (PTFE)/Teflon.

TL;DR: The basic crystallography and atomistic-modeling theory presented here reveal how the undulations of the ever-wandering steps do not, surprisingly, disturb the orientations of the attached 2D-nuclei, whose direction remains robust owing to complementarity between the meandering step and h-BN counterpart if their kinks have similar size of negligible misfit.

TL;DR: It is revealed how topographic curvature of lithographically designed substrate features govern the strain and growth dynamics of triangular WS2 monolayer single crystals, allowing strain engineering of their optoelectronic properties.

TL;DR: D-loops, a new type of structural defect in carbon fibers, are presented, which have highly detrimental effect on their mechanical properties and can define a new fundamental upper limit to their strength.
