What, you may ask, is aerogel? Aerogels are the world's lightest solid materials, composed of up to 99.98% air by volume. Aerogels are a diverse class of amazing materials with properties unlike anything else. Transparent superinsulating silica aerogels exhibit the lowest thermal conductivity of any solid known. Ultrahigh surface area carbon aerogels power today's fast-charging supercapacitors. And ultrastrong, bendable x-aerogels are the lowest-density structural materials ever developed.
It looks like frozen smoke. Aerogel insulates space suits, makes tennis rackets stronger and could be used one day to clean up oil spills. Lawrence Livermore National Laboratory scientist Alex Gash shows us some remarkable properties of this truly unique substance.
