TL;DR: Nonreciprocity in dynamic one-dimensional phononic crystal systems like the one presented here offer opportunities to create phononic diodes that can serve for rectification applications.

TL;DR: In this paper, the authors used discrete element simulations to relate the chain mail's micro-structure to macro-scale properties and to interpret experimental measurements, and they found that chain mails, consisting of different non-convex granular particles, undergo a jamming phase transition that is described by a characteristic power-law function akin to the behaviour of conventional convex media.

TL;DR: The relationship between the electrical properties and structure evolution of single layer graphene was studied by gradually introducing the gallium ion irradiation to show a controllable method to tune the properties of graphene.

TL;DR: It is demonstrated that loading-unloading cycles under large load can lead to a pronounced improvement in stiffness of graphene grown by chemical vapor deposition (CVD), and the Young's moduli of the stretched CVD graphene membranes can be improved to ∼1 TPa, closing to the value of the pristine graphene.

TL;DR: It is shown by X-ray scattering that nanoparticle membranes formed at air/water interfaces exhibit a small but significant ∼6 Å difference in average ligand-shell thickness between their two sides, which opens up new avenues for designing nanoparticle superstructures.
