I believe that everyone knows a little about the role of superconductors. The material of this kind of zero resistance can raise the current electronic technology to an unprecedented height if it can be used on a large scale. The current difficulty lies in the need to turn a specific material into a superconductor at a very low temperature (near absolute zero). .

Recently, Mikhail Eremets of the Max Planck Institute for Chemistry in Germany and colleagues found that the superconductivity of lanthanum hydride (LaH10) occurs at a temperature of 250K or -23 °C, which is quite close to normal temperature.

The researchers took a sample of base metal, only a few microns in size, into a perforated metal foil filled with liquid hydrogen, then connected the device to the wire and applied a pressure of 150 to 170 GPa – equivalent to 1.7 million Half the standard atmospheric pressure or half of the Earth’s center pressure. Next, the researchers bombarded the sample with laser light, combining helium and hydrogen to form a hydrazine hydride, and finally measuring the structure and composition of the material with an X-ray beam.

Although the pressure exerted by the team on the material is unlikely to be applied, it is clear that we are taking a big step toward the 0°C room temperature superconductor. The next goal of the researchers is to find superconducting properties under normal pressure. The magical compound.
