A team of researchers from the University of
California (UC) Irvine, HRL Laboratories and the California Institute of
Technology have developed an ultralight material out of metal – with a density
of 0.9 mg/cc – about one hundred times lighter than Styrofoam
The new material redefines the limits of
lightweight materials because of its unique “microlattice” 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,
micrometer and millimeter scales.
