7 Weird Materials In The World You Won't Believe
7 Weird Materials In The World You Won't Believe 1. Nitinol nitinol wire Nitrogen Titanium also known as Nitinol is a metal alloy of Nitrogen and Titanium. It exhibits unique properties of superelasticity and shape memory. When it undergoes deformation due to some external force at a temperature, it remains in its deformed shape even when the external force is removed. But it regains its original shape upon heating. It shows both the properties superelasticity and shape memory effect depending upon the temperature. It exhibits the shape memory effect below the transformation temperature and above that temperature it behaves superelastically. 2. Aerogel Aerogel is 99.8% air that makes it the world's lightest solid. It is a synthetic porous ultralight material of extremely lower density. It is derived from a gel therefore, called aerogel. It is also known as blue smoke or solid cloud. It is prepared by extracting liquid component of a gel by a process in which liq...
