[TECHCRUNCH] It’s official: LK-99 isn’t a room-temperature superconductor

Well, maybe we learned something about materials science so this whole thing wasnt a waste.

official

LOL as if there's an office that decides!

This is the best summary I could come up with:

The glimmers of hope that kept the story in the news for weeks appear to be the result of impurities in the original samples.

Dozens of studies published in the last week or two have coalesced around the conclusion, less than a month after a sensational preprint paper was published by a team at the Quantum Energy Research Centre, a small company housed in the basement of a modest apartment building in Seoul, South Korea.

The Korean team made waves when it published preprints on July 22, claiming to have created a material that exhibited superconductor-like properties at ambient temperature and pressure.

What’s more, the material was made of plebeian ingredients: lead, copper, phosphorus and oxygen.

A video released by the team showed it partially levitating above a magnet, and when probing it for electrical resistance, they noticed a sharp drop around 104.8°C.

In most cases, that’s not a problem; preprints have allowed many fields to move more quickly than the traditional peer-review process allows, and most scientists aren’t making outlandish claims in their preprints.
