THE ROOM-TEMPERATURE SUPERCONDUCTOR THAT WASN’T

Summary from the TLDR newsletter

LK-99 is a complicated chemical. While it isn't a room-temperature superconductor, it has many interesting properties. This article takes a look at some of these properties to explain why LK-99 behaves the way it does. The nature of LK-99 made it difficult for scientists to determine the source of its behaviors.
