| Hendrik Schon claimed to have found a way of injecting electric charge into organic crystals, enabling him to turn insulators into conductors. |
| We used these concepts to define conductors, insulators, and semiconductors, and showed one means of altering the conductivity of semiconductors. |
| Snow pack and other natural insulators can keep the frogs sufficiently warm during their winter hibernation. |
| Did you know that overweight people tend to act as insulators and keep heat in? |
| Arctic and boreal mosses, for example, are effective insulators that minimize heat transfer from the soil surface to the underlying soil. |
| Unlike low-temperature superconductors, which are metals, high-temperature superconductors are insulators in their normal state. |
