Room temperature superconductivity, LK99, reproduction, these two days the most popular technology circle is probably these words。In short, a Korean physical science team recently published a paper claiming to have discovered the world's first superconductor material at room temperature and pressure, which they named LK99.。What is Superconductor?？The core feature is that the resistance is zero, what is the concept of zero resistance？To know that we are now in an era of full electrification, and this material can be used in a variety of electrical equipment, another magical property of superconductors is completely diamagnetic, superconducting materials themselves in the case of no external force can repel the magnetic field, superconducting magnetic levitation is the use of this principle。That's why this video exploded. Laboratories in China, the United States and Russia are using a magnet to verify the diamagnetic properties of South Korea's latest superconducting material, LK99.。As you can see, the magnet in the video, no matter the positive and negative poles are flipped, the small material on it stands up instead of flipping directly like an iron sheet。But things are far from simple. The Koreans said ten days ago that they had discovered new materials and even sent out how to make them.。But even so, it took labs around the world more than ten days to get a few fragments the size of toothpicks out.。You know, such a small fragment can only be initially verified that it has a certain degree of diamagnetism, and to verify zero resistance, you need to burn out more and larger pieces of material.。To finally prove that this material can achieve room temperature superconductivity, regardless of the shape, size, weight of the material, or strict experimental conditions and processes, are indispensable.。And the current LK99 can be said to have just begun, even the laboratory has not come out。But if, I mean, if South Korea's LK99 does pass the next zero resistance test this time, then this finding is more than one dimension higher than the impact of ChatGPT.。The mineral found on the planet Pandora in the sci-fi movie Avatar that makes humans go out of their way to kill is a room temperature superconductor.。
