World’s first superconductor that works at room temperature, a new step to revolutionize many industries

It was one of the objectives of the scientific community to ensure that some superconducting materials do not depend on very low temperatures to conduct current without showing resistance. 

The University of Rochester in the United States has announced a new milestone in scientific research. The team Ranga Dias, assistant professor of mechanical engineering and physics and astronomy, has achieved such temperatures up to 15 ° C, the highest achieved so far. 

This result is a milestone for science as it represents an advance to achieve efficiency when handling and manufacturing certain components. Superconductivity, for those who do not know it, is a quality of certain materials that allow an electric current to move through that material at high speed and with little resistance, but it needs to be well below 0ºC.

Until now, laboratories operating with this type of superconducting material had to reach -140ºC. This translates into a huge expense for any project, hence the researchers are looking to maintain the levels and quality of superconductivity at higher temperatures and save the cost of air conditioning.

This is not the only benefit, Dias assures that these materials that have been searched for years ” can definitely change the world as we know it “. The dependence on these very low temperatures had until now prevented superconducting materials from being applied in a multitude of technology sectors where it had been predicted that it would cause a revolution. 

The University of Rochester gives as an example of new electrical networks that do not suffer the loss of up to 200 million megawatt-hours (MWh) that cables currently suffer due to their resistance. Superconductors could also drive the transformation of transport, medical tools such as MRIs and magnetocardiography, as well as the memory of many devices.

Co-author of the discovery, Ashkan Salamat of the University of Nevada Las Vegas explains that ” we live in a semiconductor society, and with this type of technology, you can create a superconducting society where you will never need things like batteries again .”

The result of the research has been published on the cover of the journal Nature. Dias and Salamat’s team combined hydrogen with carbon and sulfur to photochemically synthesize carbonaceous sulfur hydride derived from simple organics in a diamond anvil cell. The carbonaceous sulfur hydride exhibited superconductivity at approximately 58 degrees Fahrenheit and a pressure of approximately 39 million pounds per square inch (psi).

The next challenge, Dias explained, ” is to find ways to create the superconducting materials at room temperature at lower pressures, so it will be economical to produce them in larger volumes .”
