Euronews : The record for the world’s lightest material has been claimed by a new material called aerographite. Fabricated by Matthias Mecklenburg of Hamburg University of Technology and his colleagues, aerographite consists of interwoven threads of carbon nanotubes, each about 15 nm in diameter. With a density of just 0.2 mg/cm 2, the mesh-like material is so light that the slightest movement in the lab stirs up currents that can blow it away. Mecklenberg envisions using aerographite for applications, such as filtration and catalysis, for which both lightness and a large surface area are needed.
