American scientists create the lightest substance in the world

Comprehensive media reported that in the latest issue of Science, a US research team announced that they have created the lightest substance in the world. This material is composed of a number of tiny hollow metal tubes arranged diagonally across and leaving a small space between the tubes.

U.S. Developed Substances Lighter than Plastics The University of California at Irvine, HRL Laboratory, and the California Institute of Technology have developed a new, "world's lightest material," with a density of only 0.9 milligrams per cubic centimeter. , It is 100 times lighter than the commonly used polystyrene foam, and it is still metallic.

The researchers said that the substance is 100 times lighter than Styrofoam and has "ultra-high energy absorption" characteristics. The potential use of this material is a new generation of batteries and shock absorbers.
