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 samp…

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…

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 part…

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 …
