Using ‘Frozen Smoke’ in Emerging Technologies

Aerogel

Aerogel (sometimes referred to as frozen smoke) is an emerging technology in the material science field that has actually been around for quite a long time. It was initially created by Samuel Stephens Kistler way back in 1931 after he had made a bet with Charles Learned. Apparently they wanted to see who could fill a gelled substance with gas first. Their bet stipulated that the gel couldn’t shrink, and as a result, frozen smoke was created. Technically referred to as aerogel, the substance feels somewhat like fragile styrene and is incredibly light. The substance is produce by first making a gel. The gel is then supercritically dried in such a way that the liquid is removed while preserving the solid matrix.  Read More →
