Hydrogen Sulfide becomes Superconductive at -70C, when placed under 1.5 million bar pressure

 

This corresponds to half of the pressure of Earth’s core. With their high-pressure experiments the Mainz researchers have thus not only set a new record for superconductivity, their findings have also highlighted a potential new way to transport current at room temperature with no loss.

For many solid-state physicists, superconductors that are suitable for use at room temperature are still a dream. Special copper oxide ceramics, so-called cuprates, took the leading positions in terms of transition temperature, i.e., the temperature at which the material loses its resistance. The record for a ceramic of this type is roughly -140C at normal air pressure -109C at high pressure. In the ceramics, a special, unconventional form of superconductivity occurs...
