Barney C, Sacligil I, Tew G, Crosby A
Soft Matter . 2022 May; 18(22):4220-4226. PMID: 35607851
Rapid expansion of soft solids subjected to a negative hydrostatic stress can occur through cavitation or fracture. Understanding how these two mechanisms relate to a material's molecular structure is important...

Bailey S, Barney C, Sinha N, Pangali S, Hawker C, Helgeson M, et al.
Mater Horiz . 2022 May; 9(7):1947-1953. PMID: 35575385
An important but often overlooked feature of Diels-Alder (DA) cycloadditions is the ability for DA adducts to undergo mechanically induced cycloreversion when placed under force. Herein, we demonstrate that the...
