No superconductivity in nickelates? It's hydrogen's fault

Last summer, it was discovered that there are promising superconductors in a special class of materials, the so-called nickelates. However, it soon became apparent that these initially spectacular could not be reproduced by other research groups. Scientists have now found the reason for this: In some nickelates additional hydrogen atoms are incorporated into the material structure. This changes the electrical behavior of the material.
