| The alloys used in medical imaging superconduct only at supercold temperatures, about 450 degrees below zero Fahrenheit. |
|
| The gyroscope rotors are covered with a layer of niobium, a metal that will superconduct when it is cooled by liquid helium. |
|
| It's a ceramic material that was the first found to superconduct above the temperature of liquid nitrogen. |
|
| In the decades that followed, we discovered that most of the elements in the periodic table superconduct, and some alloys do too. |
|
| That led to a rush to find similar materials that would superconduct at even higher temperatures. |
|
| But K. Alex Müller and J. Georg Bednorz at the Zurich laboratory of I. B. M. believed that a ceramic material might be able to superconduct at warmer temperatures. |
|
| To make this material superconduct, the researchers used a method that they have pioneered on other polymers over the past year: they built it into a so-called field-effect transistor. |
|
| National Laboratory, produced the first 10-meter-long ribbons that can superconduct electricity at 100 amperes per centimeter of ribbon width. |
