A team of US engineers say they have developed the world's lightest material which is one hundred times lighter than Styrofoam. The research has been carried out by HRL Laboratories, The California Institute of Technology and the University of California, Irvine.
The material has a unique 'micro-lattice' cellular architecture featuring interconnected hollow tubes with a wall thickness of just 100 nanometers, 1,000 times thinner than a human hair. A pioneering fabrication process allowed the team, led by HRL senior scientist Dr Alan Jacobsen, to make a material that consists of 99.99 percent open volume by designing the 0.01 percent solid at the nanometer, micron and millimeter scales.
