Iris Alexander used construction grade phosphorous which is often contaminated with sulfur. Iris replicated what seems like a very good flake of LK99 that seems to show a strong Meissner effect. This could be because of Cu2S.
Chinese paper on the theory had mentioned the need for another redox dopant (they considered either)
Chinese reproduction of superconductivity was at a much lower temperature despite their sample being purer
Looking like this is the case

I still have it but you should have seen adult people smash the crucibles and start screaming "this dust speckle just moved!!!"

Meissner – yes. The rest is not mine, so it does not deprnd on me

Many other replication attempts did not work.
Reddish pellet came out of the quartz tube after quenching.. probably not the best strategy since the sulfur would just react back with the copper and form more impurities. Meissner effect not observed in both bulk and small bits of the sample. pic.twitter.com/AzkxGvcEae

I saw this deal on DNA coated glass:

Might LK-99 benefit similarly—maybe find a structure that allows it to form in a certain manner? Make it go a little farther?
We are seeing new “gold” rush. To make a superconductor is new alchemist dream. A lot of people had tried, only a few managed to reproduce something with partial levitation.
We will have to wait for a few months, so more variety will be tried. Using gold and other elements to dope,… They should use liquid nitrogen to cool samples, which are partly levitating to see if levitation increases or not.
This would fit with Elon Musk’s dictum: “The most entertaining outcome is the most likely”.
He said that when everyone thought Prigozhin was about take Moscow but that story had the least entertaining outcome out of all possible outcomes.
