Composite Image (IMAGE) Rice University Caption A composite image shows a scanning transmission electron microscope view of an antenna-reactor catalyst particle (top left) along with electron energy loss spectroscopy maps that depict the spatial distribution of individual plasmon modes around the palladium islands. These plasmon modes are responsible for capturing light energy and transferring it to the catalyst particles. Credit D. Swearer/Rice University Usage Restrictions For news reporting purposes only.
