Superconductors allow electricity to flow without resistance, meaning no energy is lost as heat.
Researchers in the United States have unlocked secrets of high-temperature superconductors.
Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered how tiny changes in superhydride structure enable superconductivity at near room temperatures but extreme pressure — offering clues for designing more practical superconductors.
“These experiments show what the upgraded APS can do. We can now study atomic-level structures with unprecedented detail in materials under extreme pressure,” said Maddury Somayazulu, Argonne physicist.

Superconductors allow electricity to flow without resistance
Researchers revealed that superconductors allow electricity to flow without resistance, meaning no energy is lost as heat. This property makes them useful for technologies such as MRI scanners, particle accelerators, magnetic-levitation trains and some power-transmission systems.
They also highlighted that most superconductors, however, only work at extremely low temperatures — often hundreds of degrees below zero Fahrenheit. Keeping materials that cold requires complex and costly cooling systems, which limits where the superconductors can be used.
Now, researchers in the U.S. have helped take a step toward easing that limitation. They have gained new insight into a class of materials called superhydrides that can become superconducting at much higher temperatures — around 10 degrees Fahrenheit.
