LK-99 research continues, paper says superconductivity could be possible
Let's assume they're right.  Even so, they emphasize that the structure of LK99 is so finicky, so sensitive to a misplaced atom here or there, so prone to confusing performance in the real world due to inhomogeneity, that it's practically impossible to "get it right" with current materials synthesis technologies.  It's something that literally has to be grown from the bottom-up, atom by atom --- in bulk, that's essentially a UFO-tier tech.<p>And that's if their models and assumptions are correct.  If it works.<p>The way I see it, the best this material can do for us is advance our theoretical understanding of superconductivity.  There's no grand theory of how molecular/crystal structure relates to superconductivity.  But maybe we've gotten a little bit closer.
