If anyone wants more context on what's going on with this research, and the potential implications and limitations, I found this write up to be the most informative ones that I've come across:
https://arstechnica.com/science/2023/08/whats-going-on-with-the-reports-of-a-room-temperature-superconductor/
Good article. I also posted an article from The Verge that mentioned a few other details including ease of manufacturing the material easily and cheaply to be effective if the research pans out and positively identifies K-99 as a true room temperature superconductor.
So all this is exciting, but everyone still needs to take the news with a grain of salt. Don’t get discouraged though, it’s a serious breakthrough if the material is truly replicated.
So, I've been standing aloof from all this till more experiments had turned out.
This paper's synthesis makes no sense, you can't have any kind of uniforms strained lattice that way, so it would have to be a bulk characteristic superconductors which we've never seen before, ie resistance is low and on certain crystalline paths becomes fairly superconductive.
Maybe this is a random fluke and once they actually understand the Mechanics they can make a real superconductors through effective fabrication processes, but if anything this reminds me of Shockley's first point-contact transistor in structure.
