Carbon nanotubes are made of the thinnest element on earth: graphene. But while graphene itself lays flat, one atom in thickness, carbon nanotubes are, as you might expect, tubes. Their walls are made of graphene, but they behave a bit differently than flat graphene, and also are significantly different from graphene oxide (GO). Interestingly, carbon... Read more »
Graphene is often described as “two dimensional,” because it is a substance that is one atom in thickness: a flat lattice of carbon atoms. And yet, graphene’s tensile strength is roughly 200 times greater than steel. As an added bonus, graphene is also highly conductive and very flexible. Although 2D graphene was first isolated by...

Carbon nanotubes (CNTs) were first discovered in the early 1990s. They are 100 times stronger than steel and one-sixth the weight, have several times the electrical and thermal conductivity of copper and lack most of the environmental or physical degradation issues related to most metals. The drawback is that CNTs have a tendency to aggregate... Read more »
