Hydroplastic foaming of graphene aerogels and …

Direct foaming from solids is the most efficient method to fabricate porous materials. However, the ideal foaming fails to prepare aerogel of nanoparticles because the plasticity of their solids is denied by the overwhelming interface interactions. Here, we invent a hydroplastic foaming method to directly convert graphene oxide solids into aerogel bulks and microarrays, replacing the prevalent ...

Graphene One – The Graphene Fiber

Graphene is the lightest, thinnest, hardest and strongest material known to man. Its two-dimensional structure is one atom thick and is a tightly packed layer of carbon atoms heavily bonded in a hexagonal honeycomb lattice. In fact, 100,000 graphene lamellae layers stacked on top of one another would be equal to the thickness of a human hair.

XFNANO Graphene

Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. The carbon-carbon bond length in graphene is about 0.142 nanometers.
