Chinese researchers have made a groundbreaking discovery in superconductivity, developing a nickel-based superconductor that operates at ambient pressure. This breakthrough makes nickel only the third material class to exhibit superconductivity without extreme pressure conditions.
Superconductors are materials that conduct electricity with zero resistance and expel magnetic fields when cooled below a critical temperature. Until now, cuprates and iron-based compounds were the only known classes of superconductors working at relatively high temperatures. The new nickelate superconductor joins this exclusive group, offering a promising alternative for various technological applications.
The discovery has significant implications for the field of superconductivity. Most existing superconductors require extremely low temperatures or high pressures to function, making their use costly and complex. However, nickelate superconductors can operate at temperatures above -233°C (-387°F) under normal atmospheric pressure, reducing engineering challenges associated with superconducting technology.
This breakthrough could lead to practical applications in multiple industries, including power grids, medical imaging, and transportation. Superconductors are already used in MRI machines, particle accelerators, and quantum computers. The ability to achieve superconductivity at higher temperatures and lower costs could extend their use to everyday technologies.
One of the most promising applications is in power transmission. Eliminating energy losses due to resistance in power lines would make energy distribution more efficient, reducing electricity costs and carbon emissions. In transportation, magnetic levitation trains could become more widespread with the development of high-temperature superconductors, potentially decreasing their cost and making high-speed travel more accessible.
While challenges remain, the discovery of nickelate superconductors represents a significant step forward in the search for practical, high-temperature superconductors. The potential applications in energy, transportation, and advanced technology make this an exciting development for both scientists and industries.
