World’s Lightest Material (Aerographite) Created by Scientist
Scientists have created the world’s lightest material. The new carbon nanomaterial, called Aerographite, weighs 0.2 milligrams per cubic centimeter. That’s less than a quarter the weight of the last record-holder, a nickel-phosphorous microlattice created by American researchers last year. And it’s six times lighter than air. Nanotechnology researchers have been working with carbon nanotubes for years (as the name suggests, these are very, very small tubes made of carbon atoms), building everything from superlight bicycles to medical implants. What the German team (from the University of Hamburg and the University of Kiel) figured out was how to build a network of branching nanotubules, thereby making the material stronger and a better conductor of electricity—two qualitie...
