University of Wisconsin MRSEC Iridescence What is iridescence? – Colors change depending on the angle at which you look at the surface Different thicknesses, like with bubbles, can create iridescence. Nano and micro features, as in the blue Morpho butterfly, also cause iridescence.

University of Wisconsin MRSEC Biomimicry of Iridescence Qualcomm has a new e-screen that mimics the iridescence of the blue Morpho butterfly. The screen gets brighter in sunlight.

University of Wisconsin MRSEC The Lotus Effect Lotus leaves and nasturtium leaves are self-cleaning due to nano and microscale structures and a waxy coating. Together these features create a superhydrophobic surface. Close-up of a nasturtium leaf, which exhibits the Lotus Effect, with a droplet of water
