Physicists from the National University of Singapore (NUS) have synthesized very pure superconducting materials and redefined the critical role of hydrogen in the newly discovered nickel-oxide superconductors.

Their findings were published concurrently in the journals Nature Communications and Physical Review Letters.

Superconductivity is an exciting phenomenon where electrical resistance disappears, and it holds transformative potential for revolutionizing energy technologies. Despite its potential, the origin and fundamental mechanism of superconductivity remain one of the greatest mysteries in physics.
