World's Lightest Solid — Now "Made in China"


From the New York Times:


"Bragging rights as the creator of the world's lightest material now move from the United States to China. Carbon aerogel is about one-sixth the density of air, or 0.16 milligrams per cubic centimeter, handily besting the metal lattice that weighed in at 0.9 milligrams per cubic centimeter (100 times as light as Styrofoam) and was forged in 2011 by a team of researchers from the California Institute of Technology; the University of California, Irvine; and HRL Laboratories."


"Scientists from Zhejiang University in China revealed last week what they say is the world's lightest solid material, a mass of atom-thick carbon sheets called carbon aerogel [above]."

If the ρ value for the material is less than air, why isn't it buoyant?

Academic plagiarism and fraud has been a problem in China, where some say professors are given an incentive to cheat because they're often evaluated on the number, rather than the quality, of papers published.
