Researchers Develop The World’s Lightest Material
by Three groups of researchers have jointly developed a metal that 99.99 percent consists of air. It weighs only 0.9 milligrams per cubic centimeter and would thus the lightest metal and material in the world.
To build the metal as a three-dimensional framework, the material almost entirely consists of air. With its density of 0.9 milligrams per cubic centimeter is the new material a hundred times lighter than Styrofoam, but relatively strong. Thus, the metal frame strongly compressed and bounce back fully. Therefore the ultra-light metal would be used metal such as padding or sound insulating material. Also used as a material for electrodes in batteries would be possible.
The new material was by researchers at HRL Laboratories, the American Irvine-University and the California Institute of Technology developed. They used a mold which was coated with nickel, then the mold was etched away. They left a framework of nickel tubes with a diameter of about 100nm. The researchers did not mention on what scale the material can be produced and what the costs are. The material was commissioned by the U.S. defense organization DARPA developed.
