Scientists at the Lawrence Livermore National Laboratory have created aerogels made of diamonds. Aerogels are gels where the inner liquid has been replaced with a gas leaving a porous solid matrix that has a very low bulk density. To make the diamond aerogel, scientists constructed a carbon aerogel that was pumped full of neon gas and pressurized using a diamond anvil. Under high pressure, the Aerogel was heated using high-intensity lasers. The high heat and pressure simulated the conditions under which diamonds form naturally within the Earth. The resulting nanocrystalline diamond aerogel is strong, light, completely transparent, and biocompatible.
