Spiropyrans are chemicals that change color when you shine light on them—a useful property in many areas of medicine and technology. Now 3mE’s Georgy Filonenko (MSE) and his colleague, Richard Janissen at the Faculty of Applied Science have discovered a new use for these so-called photochromic molecules—visualizing stresses in solid polymers. Their research is published in the Journal of the American Chemical Society.
