Researchers have reported an environmental transmission electron microscopy technique that has allowed in situ visualization of the atomic changes of a metal surface in an electric field under ambient conditions. The activation of oxygen gas molecules by electron tunneling was found to result in atomic migration that could be followed progressively. It is hoped that the tunneling-electron-attached-gas process will provide valuable insight for the development of nanoparticle catalyst and quantum material applications.

Read moreRare 'Lazarus superconductivity' observed in promising, rediscovered material
A team of researchers has observed a rare phenomenon called re-entrant superconductivity in the material uranium ditelluride. Nicknamed 'Lazarus superconductivity,' the phenomenon occurs when a superconducting state arises, breaks down, then re-emerges in a material due to a change in a specific parameter — in this case, the application of a very strong magnetic field. The discovery furthers the case for uranium ditelluride as a promising material for use in quantum computers.
