Researchers from University of California Irvine, HRL Laboratories and the California Institute of Technology have developed the world’s lightest material with a density of 0.9 mg/cc. The new material redefines the limits of lightweight materials because of its unique “micro-lattice” cellular architecture. The researchers were able to make a material that consists of 99.99 percent air by designing the 0.01 percent solid at the nanometer, micron...
