According to the paper: Tc = 110 K, or around -163 °C. This is still pretty "cool", the existence of room-temperature superconductivity remains unverified. But

According to the paper: Tc = 110 K, or around -163 °C. This is still pretty "cool", the existence of room-temperature superconductivity remains unverified. But assuming this paper is true, it means the material would still at least be a legitimate high-temperature superconductor in its own right, and the original claim would probably be cleared from being a deliberate fraud.
