- A_D_E_P_T 3y agoI'm going to assume that Ranga Dias is having a very bad week. His major discovery, assuming it's real, is room-temp superconductivity in nitrogen-doped lutetium hydride. Trouble is, anything which contains lutetium is going to be intrinsically more scarce and much more expensive than the lead-and-copper RT superconductor that was announced a few days ago. Doped lutetium crystals are also much more difficult to prepare -- and, even more troublesome, it seems they only work at 1 GPa pressure, which is absolutely non-trivial and makes them much more difficult to utilize than commonplace superconductors that can simply be cooled with LN2. ...Oh, and it might not even be real. [1] To have a different research group discover your holy grail, as you're stuck defending yourself from misconduct allegations, must be an incredibly bad feeling.

- inglor_cz 3y agoTiming, yes, but the Korean paper seems to be a lot more verifiable/falsifiable. No obfuscations and the method that they describe only needs some fairly basic reagents and equipment for replication, plus a few days' worth of time. If they are wrong, we should know pretty soon.
