| 1 | Another new class of superconductors, based on iron instead of copper, was discovered a couple of years ago. | |
| 2 | The room temperature superconductor has been the "snark" of modern materials science... | |
| 3 | He said he hoped that the new tools would one day be able to shed light on new types of superconductors. | |
| 4 | At low temperatures, electrons in the superconductors flow collectively, unfettered by resistance. | |
| 5 | Such materials could have limitless applications if they could be made to superconduct at room temperature. |
