However, since 1987, high-temperature superconductivity has emerged as a solution offering materials (predominantly copper oxide or cuprates) that exhibit superconductivity at 30 Kelvin (-243 degrees ...

Superconductivity the ability of some materials to conduct electricity with no energy loss holds immense promise for new technologies from lossless power grids to advanced quantum devices.

A new copper-free high-temperature superconducting oxide, (Sm-Eu-Ca)NiO₂, has been synthesized, exhibiting superconductivity at approximately 40 K under ambient pressure.

But certain copper oxides, known as cuprates, maintain their superconductivity at temperatures reaching -138 degrees Celsius or -216.4 degrees Fahrenheit—still cold, but significantly warmer ...
