Shu Yang of the School of Engineering and Applied Science discusses research about combining the related structural color and water-repelling properties found in butterfly wings.
PHILADELPHIA — Making uniform coatings is a common engineering challenge, and, when working at the nanoscale, even the tiniest cracks or defects can be a big problem. New research from University of Pennsylvania engineers has shown a new way of avoiding such cracks when depositing thin films of nanoparticles.
PHILADELPHIA — The colors of a butterfly’s wings are unusually bright and beautiful and are the result of an unusual trait; the way they reflect light is fundamentally different from how color works most of the time.
A team of researchers at the University of Pennsylvania has found a way to generate this kind of “structural color” that has the added benefit of another trait of butterfly wings: super-hydrophobicity, or the ability to strongly repel water.
This weekend, Penn hosted the first Ivy Plus Symposium and workshops for diverse scholars, a national conference designed to encourage exceptional undergraduate students to pursue advanced training in the sciences, technology, engineering and mathematics, or STEM, fields.
Edward Rock of the Law School, Michael Kearns of the School of Engineering and Applied Science and Al Filreis of the School of Arts and Sciences are highlighted for their involvement with Penn’s Coursera classes.
