10 Interesting Futuristic Materials
1. Aerogel Aerogel holds 15 entries in the Guinness Book of Records, including "best insulator", and "lowest-density solid". Sometimes called "frozen smoke", aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon. 2. Carbon nanotubes are chains of carbon held together by the strongest bond in all chemistry, the sacred sp2 bond, even stronger than the sp3 bonds that hold together diamond. 3. "Metamaterial" refers to any material that gains its properties from its microscopic structure rather than bulk composition. 4. We're starting to lay down thick layers of diamond in CVD machines, hinting towards a future of bulk diamond machinery. 5. Diamonds may be strong, but aggregated diamond nanorods (ADNRs) are stronger. 6. Amorphous metals, also called metallic glasses, consist of metal with a disordered atomic structure. 7. A superalloy is a generic term for a metal that can operate at very high temperatures, up to about 2000 °F (1100 °C). 8. 9.
