UrduIrvine, Calif., Dec. 5, 2024 — Scientists at the University of California, Irvine have uncovered the atomic-scale mechanics that enhance superconductivity in an iron-based material, a finding published recently in Nature. Using advanced spectroscopy instruments housed in the UC Irvine Materials Research Institute, the researchers were able to image atom vibrations and thereby observe new phonons –quasiparticles that carry thermal energy –at the interface of an iron selenide (FeSe) ultrathin film layered on a strontium titanate (STO) substrate.

X-ray Measurements Reveal an Unexpected Role for Copper in Photocatalysts
Copper is a promising catalyst for converting carbon dioxide into reduced species, a step in converting carbon dioxide into fuels. Although often initiated by electrical energy, this reaction can also be achieved using solar energy. In this work, scientists used X-rays to investigate how copper catalysts change when operating only with light and no applied electricity. The work found that the copper plays an unexpected role, producing an oxidized, not reduced, species.
