The critical temperature (Tc) >= 400 K or about 127 C, so apparently this material requires relatively high heat to reach superconductivity.

This is unusual, superconductivity is a low temperature phenomenon. Recently though, other researches have claimed room temperature superconductivity at high pressures, but low temperatures.

Uh no, I'm pretty confident they are just saying that whatever the Tc is, it's at least 127°C. I don't think they're redefining Tc to mean that it superconducts above that temperature. That would be... interesting.
