Question
In August 2023, the Max Planck Institute reported synthesizing pure crystals of this material, which exhibited none of the properties in its sensationalized July announcement. For 10 points each:
[10h] Name this material which the namesake team of South Korean scientists believe to be the world’s first room-temperature and pressure superconductor.
ANSWER: LK-99 [accept Lee-Kim 1999 material]
[10m] The team behind LK-99 believe they observed this effect, in which a superconductor expels a magnetic field.
ANSWER: Meissner effect
[10e] The announcement of LK-99 was reminiscent of Fleischmann’s and Pons’ “discovery” of the “cold” form of this process, which was never replicated. This process occurs in the core of the Sun.
ANSWER: nuclear fusion
