Hayden Evans (Fed)

His work uses neutrons, X-rays, as well as other advanced characterization techniques to study materials for future energy economy technologies (energy generation, storage, transport, by-product remediation). His primary focus at NIST has been on examining materials for gas sequestration and storage of gases, as well as solid-state electrolyte materials for batteries.
