> We have also observed that some phases remain stable without pressure at up to 300 K and for at least 7 days.
not imply the 7days are at ambient pressure?
See page 5. The phase is stable but does not superconduct at that temperature.
to quote the conclusion:
"In conclusion, we have demonstrated that the pressure-induced/enhanced superconducting phases
with high Tc and the pressure-induced semiconducting phases in FeSe and Cu-doped FeSe can be
stabilized at ambient without pressure by pressure-quenching at chosen pressures and
temperatures. Theses pressure-quenched phases have been shown to be stable at up to 300 K and
for up to at least 7 days. The observations suggest that the recently reported room-temperature
superconductivity in hydrides close to 300 GPa may be retained without pressure, making
possible the ubiquitous applications of superconductivity envisioned"
More likey there's some deal breaking issue. The pop-sci sites wave it from the rooftops for a few weeks then we forget about it.
Edit: fixed first sentence
300K = 80F
That said, the Tc of this phase is still fairly low at about 30+ K, so this does not superconduct at room temperature, regardless of the pressure.
>retaining, at ambient via pressure-quenching (PQ), its Tc up to 37 K
>suggesting that this PQed non-SC phase is stable up to 300 K
non-SC means "not superconducting"

Anything that conducts electricity or operates with a magnetic field becomes hyper efficient, imagine how many modern machinery depends on those principles.
