No user record in our sample, but hgrbrm has activity below (stories or comments). Likely we have partial data — the full bulk-load will fill profiles in.

They measured the resistivity of a pure Cu2S sample, a sample S1 containing 95% LK-99 and 5% Cu, and a sample S2 containing 30% LK-99 and 70% Cu2S. The resistivity of the Cu2S sample has a drop of 3 to 4 orders of…
If the earth runs out of helium we will just use low field MRIs that don't require superconductors (see eg https://www.nature.com/articles/s41467-021-25441-6 ). Their resolution is lower than that of high field MRIs,…
How do you explain the almost three orders of magnitude drop in resistance in Fig. 6d in one of the original articles ( https://arxiv.org/pdf/2307.12037.pdf ) with a few LK-99 particles sprinkled here an there? There…
On page 4 they list two equivalent criteria for superconductivity: "the electric field criterion with 1 μV/cm or 0.1 μV/cm and resistivity criterion with 10^-11 Ω·cm." On the same page they write: "In various bulk…
