Attached: 1 image The first room-temperature ambient-pressure superconductor may have been developed. According to the authors, the LK-99 material can be prepared in about 34 hrs with extremely basic lab equipment (a mortar & pestle, basic vacuum, and furnace). These results could be replicated within days or weeks. Superconductivtiy would be a game changer in a lot of areas. 🧵 https://arxiv.org/abs/2307.12008
