Penn physicists discover why drying liquid crystal drops leave unusual 'coffee rings'
May 26, 2017
In previous papers, University of Pennsylvania physicists investigated the "coffee ring effect," the ring-shaped stain of particles left after drops of coffee evaporate. In a new paper published in Nature Communications, they have uncovered the complex and remarkably different behavior arising in a liquid crystal drop that is drying. The research reveals novel behavior characteristics of liquid crystals.Full Story
