TL;DR: In this paper, the antibacterial activity of four types of graphene-based materials (graphite (Gt), graphite oxide (GtoO), reduced graphene oxide (rGO), and reduced GtO) toward a bacterial model (Escherichia coli) was investigated.

TL;DR: Reduced graphene oxide (rGO)-conjugated Cu(2)O nanowire mesocrystals were formed by nonclassical crystallization in the presence of GO and o-anisidine under hydrothermal conditions, resulting in an integrated hybrid architecture where porous three-dimensional (3D) framework structures interspersed among two-dimensional rGO sheets.

TL;DR: 3D hollow hybrid composites with ultrafine cobalt sulfide nanoparticles uniformly embedded within the well-graphitized porous carbon polyhedra/carbon nanotubes framework are rationally fabricated using a green and one-step method involving the simultaneous pyrolysis and sulfidation of ZIF-67.

TL;DR: A highly sensitive tactile sensor is devised by applying microstructured graphene arrays as sensitive layers and has an ultra-fast response time of only 0.2 ms, rendering it promising for the application of tactile sensing in artificial skin and human-machine interface.

TL;DR: In this study, GO sheets with different lateral sizes are all well dispersed, and their oxidation capacity toward glutathione is similar, consistent with X-ray photoelectron spectroscopy and ultraviolet-visible absorption spectroscopic results, which suggests the lateral size-dependent antibacterial activity of GO sheets is caused by neither their aggregation states, nor oxidation capacity.
