Ohh ... this could actually be relatively big.
From abstract: "The superconductivity of LK-99 originates from minute structural distortion by a slight volume shrinkage"
There was previously research done investigating how changes in atomic structural alignment affect superconductivity (such as by cooling). I think researchers were trying to maintain the spacing that superconductors had while cool even when it was heated up. This sounds line with that other research, though I can't find the article again, please correct me if you find otherwise.
Still likely to be rather fragile and temperamental to work with ... but this seems like it's possibly legit.

- BariumBlue 3y agoYes! That was exactly what I was thinking of! I love one of the comments - "But might this physical stretching then also allow room temperature superconductors, if not why not?" They were thinking of stretching at a macro scale (like bending a bar of stuff), rather than essentially "stretching" at the chemical scale which is what I understand they did here. Super cool!
- NamTaf 3y agoIt gets even better. fwlr, in a comment further down that thread, expands: > I think the “tension axis” is more likely to be fruitful in a different way, where we find some structure e.g. a crystalline formation that happens to hold atoms apart with just the right amount of tension. But this is all very speculative - the “tension axis” is just a random thought I had while reading the article! They hit the nail on the head pretty well, I’d say!
