The National Science Foundation awarded a $484,000 Project Grant under the Engineering program (CFDA 47.041) to the University of Colorado Boulder for work spanning September 1, 2021 to August 31, 2024. The grant supports research into reversible metal electrodeposition to modulate light for optoelectronic applications. Key activities include advancing metal-based technologies through novel electrode and electrolyte design to enable tunable optical properties. A subaward of $100,000 was provided to the University of Nevada, Reno to educate students in the Intermountain West on optics and electrochemical devices through school demonstrations and development of hands-on learning kits for dynamic windows. The overall work aims to improve metal-based optoelectronic technologies with potential uses in optical gating, dynamic windows, and switchable eyewear or cameras.
