TLDR
All carbon aerogels with ultralow density and temperature-invariant super-elasticity are fabricated by facile assembling of commercial carbon nanotubes and chemically-converted giant graphene sheets, on the basis of the synergistic effect between elastic CNTs ribs and giant graphene cell walls.Abstract:
All carbon aerogels (up to 1000 cm(3)) with ultralow density (down to 0.16 mg cm(-3)) and temperature-invariant (-190-900 °C) super-elasticity are fabricated by facile assembling of commercial carbon nanotubes (CNTs) and chemically-converted giant graphene sheets, on the basis of the synergistic effect between elastic CNTs ribs and giant graphene cell walls.read more

Membranes prepared from graphene-based nanomaterials for sustainable applications: a review
TL;DR: Graphene-containing membranes (GCMs) as discussed by the authors are advanced separation devices constructed from or modified by graphene and its derivatives; these membranes not only present attractive functions and performance but also generate less residual nanomaterials afterwards, thus lowering impacts to the environment compared to those caused by directly using graphene-based materials.
