Room-temperature superconductor claims resurface: wrinkled graphite nanoflakes trap magnetic flux above 390K

Physicist skdh points out that while everyone is busy talking about AI, room-temperature superconductor claims are back on arXiv.
- New paper (arXiv:2609.15712) reports that extended grinding of bulk pyrolytic graphite followed by annealing at 670K in air creates high-density wrinkle-type defects on graphite nanoflake surfaces
- TEM imaging shows these wrinkled regions exhibit magnetic flux trapping — a key superconductivity signature — persisting up to 390K and above, i.e., beyond room temperature
- Controls: unannealed and vacuum-annealed samples show negligible flux trapping and no wrinkles, strongly suggesting wrinkled regions are the source of local high-temperature superconductivity
Note: this is a possible manifestation of local high-temperature superconductivity, an unreproduced claim that should be treated with caution.
