But this can only happen if scientists can create or discover materials that are superconductors at room temperature. In fact, a Nobel Prize will be awarded to one who succeeds in making a room temperature superconductor. Right now, the problem is that scientists have to work with superconductors at around -135 °C. This involves the use of liquid nitrogen and other methods to make extremely cold temperatures. This is of course a tedious job, which is why scientists prefer to use superconductors at room temperature. Mrs. Jin's team thinks that replacing the paired electrons with the paired fermions would result in a room-temperature superconductor.
