Graphene is the only form of carbon (or solid material) in which every atom is available for chemical reaction from two sides (due to the 2D structure). Atoms at the edges of a graphene sheet have special chemical reactivity. Graphene has the highest ratio of edge atoms of any allotrope. Defects within a sheet increase its chemical reactivity ...
The school's latest experiment uses graphene material that's 5 percent as dense as steel and ten times the metal's strength, showing what's possible when the composite is more than just a flat sheet.
TIL that Graphene is the thinnest two-dimensional material in existence and is 200 times stronger than steel. It is also the most conductive material on Earth, excelling in both electrical and ...

Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm 3, its specific strength of up to 48,000 kN·m·kg −1 is the best of known materials, compared to high-carbon steel's 154 kN·m·kg −1. Under excessive tensile strain, the tubes will undergo plastic deformation, which means the deformation is permanent. This ...
Buckypaper is one tenth the weight yet potentially 500 times stronger than steel when its sheets are stacked to form a composite. [1] It could disperse heat like brass or steel and it could conduct electricity like copper or silicon. [1]
Graphene is an atomic-scale honeycomb lattice of carbon atoms. Graphene is a crystalline allotrope of carbon in the form of a nearly transparent (to visible light) one atom thick sheet. It is hundreds of times stronger than most steels by weight. [5]
A two-dimensional semiconductor (also known as 2D semiconductor) is a type of natural semiconductor with thicknesses on the atomic scale. Geim and Novoselov et al. initiated the field in 2004 when they reported a new semiconducting material graphene, a flat monolayer of carbon atoms arranged in a 2D honeycomb lattice. [1]
