Cover: Investigating Nanoscopic Structures

Some of the most beautiful and awe-inspiring insects are blue Morpho butterflies. In Investigating Nanoscopic Structures on a Butterfly Wing To Explore Solvation and Coloration, Brittany A. Bober, Jennifer K. Ogata, Veronica E. Martinez, Janae J. Hallinan, Taylor A. Leach, and Bogdan Negru present a laboratory experiment that introduces general chemistry students to material science and nanotechnology with the use of iridescent Morpho butterfly wings. The nanoscopic structures make the wings superhydrophobic and also form a photonic crystal responsible for the structural coloration of these butterflies. Students performing the experiment alter both the color and superhydrophobicity of the wings of a preserved specimen, as shown by the image of a Morpho butterfly. The background image is a scanning electron micrograph of silver-coated wings that reveals the nanoscopic ridges of butterfly scales responsible for superhydrophobicity and structural coloration. This captivating and memorable experiment for students reinforces their understanding of the properties of light and solvation.
