Recent claims of room-temperature superconductivity have failed to be replicated by independent research groups. In 2020, a team of researchers led by Ranga Dias at the University of Rochester announced that they had discovered a material that exhibited superconductivity at room temperature under high pressure. However, multiple attempts by other research groups to reproduce these results have been unsuccessful.

For example, in 2021, a team led by Ashkan Salamat at the University of Central Florida reported that they were unable to observe superconductivity in the same material under similar conditions. Similarly, a team led by Johnpierre Paglione at the University of Maryland, College Park, reported negative results in their attempts to replicate the original findings.

The inability to replicate the original claims raises serious doubts about the validity of the reported discovery. However, it is important to note that the pursuit of room-temperature superconductivity remains an active area of research, and new developments may arise in the future. As of today, there is no conclusive evidence to support the existence of room-temperature superconductivity.
