US EditionPhysicists discover a copper-free high-temperature superconducting oxide
- On March 27, 2025, the National University of Singapore announced that Professor Ariando and Dr Stephen Lin Er Chow designed and synthesised a copper-free superconducting oxide capable of superconductivity at approximately 40 Kelvin under ambient pressure.
- The discovery builds upon nearly four decades of copper oxide superconductivity research, including the 1987 Nobel Prize in Physics, and addresses the challenge that most superconducting materials require extremely low temperatures near absolute zero to function, limiting their practical applications.
- The new NiO nickel oxide, published in Nature on March 20, 2025, demonstrates zero electrical resistance well above 30 K without lattice compression, confirming a predicted correlation between interlayer interactions and superconducting temperatures.
- Dr Chow stated, "As we predicted and designed, this non-copper-based superconducting oxide demonstrates high-temperature superconductivity under atmospheric pressure at sea level, without the need for additional compressionjust like copper oxides," highlighting the material's unique properties.
- This copper-free alternative expands the understanding of unconventional superconductivity, suggesting it may not be exclusive to copper and offering potential for next-generation superconducting materials with practical applications in modern electronics, as Professor Ariando noted, "This is the first time since the Nobel-winning discovery that a copper-free high-temperature superconducting oxide has been found to function under ambient pressure.
