Superconductors, in contrast to ordinary conductors, have a really excellent indicator of efficiency in conducting electric charge without additional losses – due to the fact that the electrons inside such a superconductor move without any counteraction and do not lose charge. However, despite their higher efficiency, superconductors have one important disadvantage – they manifest their properties only at very low temperatures, which makes their use in room conditions almost impossible. But experts from the Max Planck Research Institute in Germany do not think so.
Today, a team of specialists designed their new experiment to bring the superconductor closer to more or less normal and familiar temperatures – it managed to be raised to -23 degrees Celsius. Given the fact that usually superconductors operate at significantly lower temperatures of -270 degrees, it becomes clear that the success of scientists can not be outstanding. The basis of the material was the so-called metallic lanthanum and hydrogen gas, which were placed in a high-pressure chamber and squeezed the substance particles very strongly – about 1.7 million times stronger than atmospheric pressure.
As a result, they produced lanthanum hydride, after which it was strongly cooled and found that when the temperature rises to -23 degrees, the electrical resistance inside the material rises to zero – which indicates the possibility of potential use of the material at room temperature, as well as in other systems superconductors or even a magnetic field.
It is worth noting that the new record set for the maximum operating temperature of a superconductor has a really remarkable indicator of its stability, and therefore the experts intend to continue to work on improving their experiment and the material itself in such a way that it reaches an even higher temperature of its work.
