News: <\/strong>Recently, scientists found that the material called LK-99 is not a room-temperature and ambient-pressure superconductor.<\/p>\n

What is LK-99?<\/strong><\/h2>\n

LK-99 has been claimed by South Korean scientists as a superconductor at room temperature and atmospheric pressure. However, currently scientists have discarded their claims.<\/p>\n

What are the reasons behind discarding LK-99 as a superconductor?<\/strong><\/h2>\n

First,<\/strong> when superconductors get cold, they push away magnets, causing repulsion below their transition temperature. The South Korean video showed LK-99 partly repelling a magnet. However, independent researchers found that the material was an insulator whose impurities could be magnetized.<\/strong><\/p>\n

Second,<\/strong> the South Korean scientists saw less resistance in LK-99 around 104\u00b0C, which could mean it’s a superconductor. However, researchers found that this drop occurred due to the copper sulphide impurities present in the material<\/strong>.<\/p>\n

Hence, as per the scientists, no formal confirmation aligns with the initial declaration<\/strong> that this material can conduct electricity without resistance in regular conditions.<\/p>\n

What lies ahead?<\/strong><\/h2>\n

The LK-99 case raises concerns over misunderstandings caused in the open science competition. However, this misunderstanding shouldn’t stop open collaboration.<\/p>\n

Moreover, now, the burden lies on South Korean group to show evidence for their claim.<\/p>\n","protected":false},"excerpt":{"rendered":"
