There have been developments in high-temperature high-pressure superconductors this year, but as far as I know this is the first claim ever of a room-temperature ambient-pressure superconductor. And not just some vague "evidence for superconductivity", but every test you could possibly want with a cooking recipe to boot. That's why it's almost certainly a hoax - it's too big of a leap from current leading edge and everything one could hope for - but if someone DID stumble onto such a recipe, this is what that discovery would look like at first.
I like the physicist urge to call 10 kbar "near ambient"
I know, right? Or calling cryonics "high temperature" 😆
anything above 20 K is high to them smh
Hahaha, but to be fair, high Tc now typically refers to above the nitrogen boiling point of 77K, so 20K is a bit low even for them. I think the reference to 20K is in distinguishing between conventional vs unconventional superconductors--depending on if they can be explained by the BCS theory. When unconventional superconductor was first discovered, the highest known Tc for the conventional ones was about 20K. One could even say, therefore, calling it "high" is just experimentalists flexing to theorists.
