The code name LK-99 is a potential room-temperature and ambient-pressure superconductor. The original work started in the 1990s at Korea University.

A few days ago, the research team claimed that they’ve cracked the problem. Most importantly, the synthesis is freaking cheap and easy to make. Scientists in related disciplines skeptic about it. Since then, the experiment hasn’t been successfully replicated by others yet.

Ngl, I got hyped when I first heard this. After a few thoughts, it seems too good to be true. Academic frauds are pretty common. Ehh, I’m far from being a material expert to tell if it’s legit anyway.
