| Straw encased in an earthen shell makes for a cozy insulator, and studies show that it's more fire-resistant than timber. |
| Myelin acts as a multilamellar insulator around brain axons and is expressed by oligodendrocytes in the central nervous system. |
| One way to prevent flashover is to add some conductivity to the surface of the insulator, so charge can bleed away before it builds up. |
| Capacitance is a property best illustrated by two metal plates separated by an insulator. |
| The air trapped between layers acts as an insulator to reduce heat transmission. |
| I knew aerogel could trap small moving objects, but I had no idea it was such a good insulator. |
