Earlier this month, the science community was abuzz with news of a possible breakthrough: a substance called LK-99 that's alleged to be a room-temperature superconductor. Discovered by Lee Sukbae and Kim Ji-Hoon from Korea university, the material would be a game changer for everything from power delivery to super computers, if it works as advertised. However, after a number of scientists tried and failed to reproduce Lee and Kim's' findings, the world seems to have moved on.
But the field of superconductors is a fast-changing one. Newly-published, pre-print theoretical research generally continues to support LK-99 as having the properties required to become a superconductor; and now, internet sleuths have discovered a Korean-language update on the original LK-99 patent. This document presents further details (and also new questions) regarding the synthesis process, even as the original Korean authors reaffirm the significance (and veracity) of their discovery.
