A revolutionary technology that could change the world has yet to work

In short, why it really matters

Either high pressure or extremely low temperatures have always been needed for superconductors to work, but scientists now claim to have developed a superconducting material that only functions at 1 GPa and near room temperature. If the technology is scaled up to the production of devices, it will lead to a significant increase in efficiency and the creation of more powerful electronics.

If these claims are true, then a revolutionary discovery, could lead to a second industrial revolution. and save billions of dollars every year on the power system alone. However, this claim caused controversy in the scientific community as some scientists completely rejected the claims.

More about the study

The research team working on the development of the superconducting material is led by Ranga Dias, an associate professor in the Department of Mechanical Engineering and Physics at the University of Rochester. The team used lutetium-based superhydride to create the superconducting material. The sample was a mixture of lutetium, hydrogen and nitrogen exposed to a temperature of 200°C for several days. The sample was then compressed with a diamond anvil under a pressure of about 2 GPa and its superconducting properties were tested in the usual way while reducing the pressure.

Criticism of the discovery by other scientists

While the examples have been able to meet all the scientific requirements for superconductors, including reduced resistance and the Meissner effect, in practice all is not as great as it seems.

There were several team members be accused of violationsand an earlier article published in the scientific journal Nature was retracted.

A team of Chinese and American scientists tried to recreate the experiment. They synthesized the required compound lutetium (Lu4H23) and tried to turn it into a superconducting state. However, its results did not meet previous expectations.

The material became superconducting, but at -203 °C, not 21 °C, as the Rochester scientists had previously claimed. In addition, the required pressure was twice as high – 218 GPa instead of 1 GPa (2 million atmospheres instead of 10,000 atmospheres).

Humanity needs this technology.

The development of a room-temperature superconductor could have implications in the form of more portable medical devices, more efficient electromagnets, a safer and more efficient power grid, and even use in wind turbines and fusion power plants.

This will certainly affect ordinary household appliances, smartphones and other devices. The use of such a technology will increase the technological capacity of humanity many times over, and the scientific community will closely monitor developments in this field.
