Following the recent discovery of very high temperature conventional superconductivity in sulfur hydride (critical temperature Tc of 203 K). Experimentalist have shown results on the covalent hydride phosphine (PH3) which also exhibits a high Tc > 100 K at pressure P > 200 GPa. However, neither the exact composition nor the crystal structure of the …

Researchers at the Max Planck Institute for Chemistry in Mainz and the Johannes Gutenberg University Mainz observed that hydrogen sulfide becomes superconductive at minus 70 degree Celsius —when the substance is placed under a pressure of 1.5 million bar. This corresponds to half of the pressure of the earth’s core. With their high pressure experiments …
Ishiwata-sensei's team eager of condensed matter physics and pizza! During my visit to the University of Osaka.
This year promises much more exciting news. I was kindly invited by one of the leaders -worldwide- in the field of superconducting hydrides. His team have measured the highest superconducting transition at 250 K! (the machine in the picture)
