U.S. Army Engineer Research and Development Center (ERDC) Materials Scientist Dr. Jared Cobb demonstrates the ultra-thin polymer exhibiting thin-film interference to produce various colors. ERDC Research Chemists Drs. Matthew Glasscott, Caite Bresnahan and Tim Schutt, along with Cobb, teamed up with researchers at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory to develop the photonic integrated circuit, a new technology that captures and detects harmful water-borne contaminants in the environment.
