This is pretty crazy.

"We've seen movies with much less complex plots than this already. It's eerily appropriate that such a monumental discovery would be rife with drama. And we're still waiting for a definite announcement that yes, humanity has finally produced room-temperature, ambient-pressure superconductors. After that, there are plenty more physics barriers to crash through, as always."

"This result hints to the synthesis challenge in obtaining Cu substituted on the appropriate site for obtaining a bulk superconducting sample. Nevertheless, I expect the identification of this new material class to spur on further investigations of doped apatite minerals given these tantalizing theoretical signatures and experimental reports of possible high-TC superconductivity." Emphasis mine.

The author never once stated what the Bulk Resistivity was or would be at any Temperature T.

Is there a scientific paper out there with these T vs. R results? Until that data is shown under some kind of non-Chinese peer review, this is just more Scientific Clickbait.

A lead and copper based room temp super conductor would definitely be the holy grail of materials science with a host of revolutionary practical applications.

Seems too good to be true, so I'm not gonna hold my breath. Probably another cold fusion nothing burger, but one hopes.

It really does.

Conclusion

I am guardedly optimistic at this point. The Shenyang and Lawrence Berkeley calculations are very positive developments, and take this well out of the cold-fusion "we can offer no explanation" territory. Not that there's anything wrong with new physics (!), but it sets a much, much higher bar if you have to invoke something in that range. I await more replication data, and with more than just social media videos backing them up. This is by far the most believable shot at room-temperature-and-pressure superconductivity the world has seen so far, and the coming days and weeks are going to be extremely ****ed interesting.

"University Colorado researchers calculated that the class of LK99 material (weak interaction of Copper‒Oxygen, while minimizing hybridization) shows promise for high temperature superconductivity regardless of LK-99 actually working."

The point is this: No one has proven that LK-99 is a real superconductor at this stage. Certain "theoretics" conjecture that "doped" CuO2 combinations may show superconducting qualities but as of now, that has not been proven.

The real proof will come when it is shown that specific "doped" CuO2 combinations have Zero bulk Resistivity (R in ohms) at room Temperature (T at 293K or 20C), and that the material has high Current Density (I in Amps) capability.

Correct. It is not proven yet. "Shows promise".

Then we can agree the article

https://www.tomshardware.com/news/s...PvJXX5WT_ZfoFGWC-am5G_LbjZf3zLJ2ZwCX85kqhBN-U

has a misleading title.

In physics, this falls under what is known as "Condensed Matter Physics" and has been the topic of intense research for many years using doped cobalt's, ferrous oxides, and other mixtures.

Check out the articles by this researcher who has over 137 papers on this and related subjects:
