Congrats to Yudi and team (including former REU student Ethen Lund) on the acceptance of their paper “Molecular Damage Detection in an Elastomer Nanocomposite with a Coumarin Dimer Mechanophore” at Macromolecular Rapid Communications! We’re looking forward to seeing the rest of the special issue on Mechanochromic Polymers being put together by Yulan Chen, Michael Sommer, and Chris Weder.
