Structural color is created when a clear high refractive index liquid is placed into low refractive index microwells. ACS Materials Letters 2020, 2, 754–763.

STRUCTURAL COLOR: Nate and Sam visit Lauren Zarzar, assistant professor of chemistry at Penn State, to talk about color and a cool kitchen science experiment. Where does color come from and what makes things like opals and butterfly wings iridescent?

MIT researchers have devised a new way to make complex liquid mixtures, known as emulsions, that could have many applications in drug delivery, sensing, cleaning up pollutants, and performing chemical reactions.
