| An aerogel is a porous network of silica strands with diameters of a few nanometres. |
| To use the aerogel as a display, external magnetic fields would be used to flip the needles back and forth. |
| A sugar-cube-sized piece of aerogel made of carbon material may have an internal surface area of as much as 2 000 square metres. |
| A tennis racket-shaped canister packed with a material called aerogel will capture the particles during the flyby. |
| I knew aerogel could trap small moving objects, but I had no idea it was such a good insulator. |
| Products combining pyrethrin and silica aerogel are also available for the control of roaches. |
