Frozen Smoke
- Researchers have developed a sensor made from "frozen smoke" that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
- The frozen smoke, technically known as aerogel, is an extraordinary material.
- The name aerogel comes from the combination of the Greek word “aero”, meaning air, and “gel”, since aerogels are derived from gels.
- Aerogel can claim a low density, high thermal resistivity and a highly porous ....
