The XRDs are nearly identical. It's a dead horse.
- ycui1986 3y agoXRD used here only shows crystal lattice information for random orientated polycrystalline. It does not mean the two samples are identical. It does not prove whether they had single crystal or polycrystal. You will need a four-circle diffractometer to prove two samples are identical, that also only work on single crystal if anyone can make it.
- carabiner 3y agoXRD comparison isn't from eyeballing. The fact is, the original papers do not coherently specify "LK-99" because their equations, synth procedure, and subsequent analysis are all incomplete or contradictory. It's like they gave everyone 2 + 2 = 5 and so everyone's been trying to figure out how to get to 5, while also questioning 2 and 5 because the quality of the papers is so poor. "We do not know the composition or structure of #LK99 with any confidence." https://twitter.com/Robert_Palgrave/status/1687235756702752768 https://twitter.com/Robert_Palgrave/status/16872357567027527...
