LK-99: Replicated material does not show superconductivity

Plus: DARPA plans to capture, not kill, the next Chinese spy balloon Hopes for a new industrial revolution led by room-temperature and ambient-pressure superconductivity will have to be postponed, for now. A major research center has cast doubt on the purported properties of newly synthesized material LK-99, dismissing claims that it is a room-temperature superconductor.

[SUBSCRIBE]( Must Read [❌ LK-99: Replicated material does not show superconductivity]( The Center for Condensed Matter at the University of Maryland cited studies from China, India, and Taiwan that were unable to replicate the superconductivity of LK-99. Instead, these studies found the material exhibits common properties like diamagnetism and trace ferromagnetism. As temperature decreases, LK-99 was found to have semiconducting or insulating resistivity - far from displaying superconductivity. The initial reports of LK-99's remarkable properties came from the Quantum Energy Research Centre in South Korea. However, attempts by other scientists worldwide to replicate the material have failed to verify the claims. The focus can now shift to genuine advancements in materials science and physics.

[Innovation]( 🎈 DARPA plans to capture, not kill, the next Chinese balloon The United States Defense Advanced Research Projects Agency (DARPA) is seeking proposals for a way to capture high-altitude spy balloons like the one that was shot down earlier this year. The Capturing Aerial Payloads to Unleash Reliable Exploitation ("Capture" for short) project would allow US analysts to investigate the undamaged craft at leisure.

In 1956, he used it to describe a phenomenon wherein electrons behave quite unlike themselves in metals and attributed certain properties to this behavior.
