Caption
This cartoon shows how x-rays (yellow zigzags) reveal information about atoms' electronic structure in a nickel-oxide superconductor, where nickel atoms have red electron orbitals and oxygen-atom orbitals are teal. The larger the orbital, the more electrons in it. These studies are helping researchers understand similarities and difference between nickel- and copper-based superconductors.
