According to a press release by UC Irvine on its official website on Thursday, November 17, 2011, a team of researchers have developed what is now being believed to be the world’s lightest material.

“The trick is to fabricate a lattice of interconnected hollow tubes with a wall thickness 1,000 times thinner than a human hair.” Lead author Dr. Tobias Schaedler was quoted on the report.

The discovery was made by researchers from University of California, HRL Laboratories and the California Institute of Technology, and the report was also published at journal Science on Friday.

The said new substance is being noted to be made out of tiny hollow metallic tubes arranged into a micro-lattice, criss-crossing diagonal pattern with small open spaces between them.

As noted in the report, the ‘world’s lightest material‘ consists of 99.99 percent air by designing the 0.01 percent solid at the nanometer, micron and millimeter scales, and is also 100 times lighter than Styrofoam.

Scientists said they believed that the new material, which has a density of 0.9 milligrams per cubic centimeter, can likely be used in the future such as in batteries, thermal insulation, and shock absorbers.
