Taiwan University is live streaming now.

Here's the link:


They confirmed that LK-99 exhibits diamagnetism at around 1 hour and 10 minutes in the stream.

Experts are pressing "x to doubt" on the Korean team's claims

We'll see within a week.

A week later, results have come up short.

Ah well.

It's not Joever just yet, but yes, a peer reviewed paper and published by a highly reputable source would be much appreciated.

I also hope this doesn't kill disinterest in the hypothetical breakthrough itself, as at the very least it could lead to a true SC sometime down the line.

I hope it doesn't take a year .

Korea University Confirms the Crystal Structure of LK-99 Matches Original Paper And Sample Passes Purity, Uniformity Standards

Researchers at Korea University of Energy and Technology confirmed that the crystal structure of a sample of ‘LK-99’, proposed room temperature superconductor, is the same as the crystal structure presented in the original papers by Sukbae Lee, Jihoon Kim et al. The College of Energy Engineering is the only external institution conducting research after receiving samples of LK-99 from the Quantum Energy Research Institute.

A researcher at Korea Energy Engineering University, who is participating in the LK-99 study, said in a phone call with the Digital Times on the 8th, “As a result of analyzing the X-ray diffraction structure of the sample, it was confirmed that the fine crystal structure of the sample is the same as that presented in the paper.” said.

The researcher said, “If you look at the microcrystalline structure, you can estimate the possibility even if you cannot confirm the physical properties of the material. As a result of confirming the microcrystalline structure with X-rays for the analysis of LK-99, the Quantum Energy Research Institute has a different crystal structure and The crystal structure confirmed in the sample was the same,” he said.

It's pretty much over. Manifold has tanked to 13% in response to this paper. Still possible that the independent labs studying the original LK-99 samples confirm that they are RTSCs, but I'm not holding my breath.
