An uncommon materials, named LK-99, has been introduced to the world as a superconductor that will carry electrical energy at room temperatures with zero resistance. On Twitter – or X, “LK-99” has been a trending subject in latest days, and fans have hailed what they consider to be a long-sought holy grail of physics, one that will rework on a regular basis life with new applied sciences to unravel local weather change and make levitating trains commonplace. Superconducting supplies exist already in locations like MRI machines and a few quantum computer systems, however solely show their superconducting properties at extraordinarily low temperatures, making them impractical for vast use.
The saga began when a staff of South Korean scientists, most working for a tiny startup firm, posted two experiences that described their method for making LK-99 and the measurements that they mentioned confirmed the fabric’s superconducting prowess. (The identify of the fabric comes from the initials of the surnames of two of the scientists – Sukbae Lee and Ji-Hoon Kim – and the yr 1999, once they say they first synthesised LK-99.) Most strikingly, they supplied a video displaying a small pattern partially levitating over a magnet. The levitation, they mentioned, demonstrated the Meissner impact, which ensures zero magnetic subject inside a superconductor.
Alex Kaplan, who had majored in physics at Princeton College, came upon about LK-99 on Hacker Information, a information aggregation web site. “I used to be simply shocked,” Kaplan mentioned. That evening, he shared his pleasure on Twitter. With that tweet, which has acquired greater than 132,000 likes, Kaplan joined a gaggle of LK-99 followers who propelled pleasure on social media over the previous week. A lot of the fans should not consultants, nonetheless. Kaplan, for instance, works as the top of a espresso product.
The scientists who research superconductivity have been quieter. The scepticism stays, as a result of the information supplied to date falls wanting being convincing, many consultants say. “That information is extraordinarily suggestive,” mentioned Sankar Das Sarma, director of the Condensed Matter Principle Heart on the College of Maryland. He identified, as an example, that on the temperature that Korean scientists declare LK-99 turns right into a superconductor, {the electrical} resistance drops, however to not zero. The resistance of the fabric, manufactured from the mineral apatite with among the lead atoms changed by copper, is about 100 occasions greater than pure copper and different good conducting metals. The video can also be not definitive, as a result of non-superconducting supplies together with graphite can even partially float in the identical approach. The Korean Society of Superconductivity and Cryogenics has convened a panel to confirm the findings.
