| 1 | Niobium is a soft metal used in producing superconducting steel. | |
| 2 | This scanning tunneling microscope image of a bismuth superconducting compound shows a characteristic checkerboard pattern. | |
| 3 | The niobium superconducting cavities shown here could prove useful for waste transmutation. | |
| 4 | They also found that the time taken to reach this superconducting state depended on the intensity of the beam. | |
| 5 | Researchers still need to find a way to make entangled superconducting circuits last longer. |
