The Art of Engineering: Manganese Oxide Nanowires
This image shows a hollow, bird’s-nest-shaped three-dimensional structure composed of asymmetrically self-assembled manganese oxide nanowires from the lab of Harold Kung, professor of chemical and biological engineering. Researchers in the lab prepared these structures as electrode materials for batteries and catalysts for electrochemical reactions. The narrow diameter and elongated shape improve electrochemical performance. Courtesy of Xin Zhao.
