TL;DR: The fabrication of highly porous graphene-derived carbons with hierarchical pore structures in which mesopores are integrated into macroporous scaffolds are demonstrated, which makes them potentially promising for diverse energy storage devices.

TL;DR: A high-performance supercapacitor incorporating a poly(ionic liquid)-modified reduced graphene oxide (PIL:RG-O) electrode and an ionic liquid (IL) electrolyte with enhanced compatibility with the IL electrolyte, thereby increasing the effective electrode surface area accessible to electrolyte ions.

TL;DR: In this article, the fabrication and design principles for using silver-nanowire (AgNW) networks as transparent electrodes for flexible film heaters are described, and a transparent film heater is constructed based on uniformly interconnected AgNW networks, which yields an effective and rapid heating of the film at low input voltages.

TL;DR: A practical route to the production of solution phase transferable graphene sheets using ionic liquid polymers (PIL) as a transferring medium is developed and these PIL-modified graphene sheets in aqueous phase are readily transferred into the organic phase.

TL;DR: A VO2-based thermochromic film with unprecedented mechanical flexibility is demonstrated by employing graphene as a versatile platform for VO2, effectively functions as an atomically thin, flexible, yet robust support which enables the formation of stoichiometric VO2 crystals with temperature-driven phase transition characteristics.
