TL;DR: In this paper, a strategy for toughening graphene oxide (GO) through synergistic interfacial interactions between GO monolayers and ultrathin layers of strongly interacting poly(vinyl alcohol) (PVA) was proposed.

TL;DR: It is found that prior to the critical Depth, the monolayer MoS2 film can return to the original state after completely unloading, while there is hysteresis when unloading after the critical depth and residual deformation exists after indenter fully retracted, indicating plasticity.

TL;DR: Interestingly, van der Waals interactions, which are seldom highlighted in the fabrication of strong GO-polymer interfaces, are found to also provide significant crack-bridging capabilities when the polymers possess large side groups.

TL;DR: In this paper, a tin dioxide nanorods/ethylenediamine-modified reduced graphene oxide (SnO2/EDA-rGO) heterojunctions with selective adsorption and electronic structure modulation were engineered for highly sensitive and selective detection of NO2 at room temperature.

TL;DR: In this paper, a hierarchical assembly of SnO2-rGO/SnS2 heterostructure with 2D reduced graphene oxide (rGO) acting as a transfer highway to bridge n-type SNO2 nanowires and n- type SnS2 nanoflakes, resulting in novel ternary n-g-n junctions for the improvement of charge transport efficiency and thus enabling ultra-sensitive NO2 gas detection.
