A team of American scientists reported that room temperature superconductivity has been observed in hydrides of organic sources under high pressure. < / P > < p > superconductivity means that electric energy can pass through the material with zero resistance. But strictly speaking, it means that the resistance is zero at a certain temperature. Superconductors not only have the characteristics of zero resistance, but also can be completely diamagnetic, which makes superconductors have almost no energy loss in the transmission process, and can carry stronger current per square centimeter of superconductors; while ordinary materials consume a lot of energy in the process of conduction. < / P > < p > however, this effect was initially observed at temperatures close to absolute zero. At present, most superconductors work only at temperatures close to absolute zero. If room temperature superconductivity is realized, it is expected to improve the efficiency of electrical conductors and devices by minimizing heat generation. Therefore, since the first discovery of superconductivity in 1911, it has been the goal of many scientists to find superconductors that can be achieved at room temperature. Previous studies have shown that hydrogen rich materials can increase the superconducting temperature to about – 23 ℃ under high pressure. This time, Lango Diaz, a scientist from the University of Rochester in the United States, and his colleagues raised the temperature at which zero resistance can be achieved to 15 ℃ in the latest research, but this was achieved in a photochemical synthesis of ternary carbon containing hydrogen sulfide system under 267 billion Pascal pressure. < / P > < p > the pressure in this study is about 1 million times of the typical tire pressure. In the new system, the element precursors (carbon, sulfur and molecular hydrogen) are transformed into superconducting materials by laser and pressure. The superconducting pressure reaches the critical value with the increase of the experimental pressure. < / P > < p > Room temperature superconductivity has always been the Holy Grail to be picked up, and now this achievement has important guiding significance for the exploration of superconductivity phenomenon and even the realization of room temperature superconductivity which can be applied. The team’s next goal will be to achieve room temperature superconductivity under ambient pressure. Controlling the system chemically may help reduce the pressure needed, the researchers said.
