UPTON, NY Scientists characterized how the electronic states in a compound containing iron, tellurium, and selenium depend on local chemical concentrations. They discovered that superconductivity (conducting electricity without resistance), along with distinct magnetic correlations, appears when the local concentration of iron is sufficiently low; a coexisting electronic state existing only at the surface (topological surface state) arises when the concentration of tellurium is sufficiently high.

Study Reveals Platinum s Role in Clean Fuel Conversion
Identifying specific platinum atoms activated in a water gas shift reaction catalyst could guide the design of less costly efficient catalysts
February 10, 2021
Lead author Yuanyuan Li, a research scientist at Stony Brook University s Materials Science and Chemical Engineering Department who has a guest appointment in Brookhaven Lab s Chemistry Division, performs an analysis on a sample using an infrared spectrometer.
UPTON, NY Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University (SBU), and other collaborating institutions have uncovered dynamic, atomic-level details of how an important platinum-based catalyst works in the water gas shift reaction. This reaction transforms carbon monoxide (CO) and water (H
