A large class of metal polyhydrides has been theoretically proposed and experimentally realised to promote near-room-temperature superconductivity under high pressures. In this work, we theoretically reported the near-room-temperature superconductivity in a symmetrically Mg/Ca substituted hexahydride, i.e...
Researchers at the George Washington University have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity. Superconductivity is the lack of electrical resistance and is observed in many materials when they are cooled below acritical temperat...
Here, we report H2 molecular type hydrides with an exceptional near room-temperature superconductivity of 270 K in compressed NaH10 and a Tc of 152 K in NaH12, where H atoms solely constitute H2 units, and Na-H forms ionic bonds. Our first-principles calculations unveil that the high Tc ...
5. An important discovery leading to room-temperature superconductivity is the pressure-driven disproportionation of hydrogen sulfide (H2S) to H3S, with a confirmed transition temperature of 203 kelvin at 155 gigapascals3,6. Both H2S and CH4readily mix with hydrogen to form guest–host structures ...
mechanism of the near-room temperature superconductivity. Our investigation greatly boosts the field of high-pressure ultrafast science, which can be extended to other near-room temperature superconductors and other quantum materials. Thus, we foresee the dawn of a promising unexplored frontier area, ...
This image shows near room temperature superconductivity in superhydrides at megabar pressures. Credit: Russell Hemley/GWU Theory suggests that metallic hydrogen should be a superconductor at room temperature; however, this material has yet to be produced in the lab. Metal superhydrides are packed ...

Rare earth hydrides have been found to exhibit near room temperature superconductivity benefiting from the chemical pre-compression induced by the interaction between hydrogen and tetragen atoms1,2. A typical example among them is the experimental discoveries of superconductivity at the critical temperature...
