Christopher W. Barney,* Ipek Sacligil,* Gregory N. Tew,* and Alfred J. Crosby* recently published a paper entitled, "Linking cavitation and fracture to molecular scale structural damage of model networks" in Soft Matter. Needle-induced cavitation (NIC) protocol is applied to a set of model end-linked PEG gels with quantitatively linked elastic and fracture properties. This quantitative link between molecular scale structure and macroscopic properties is exploited to experimentally probe the relationship between cavitation, fracture, and molecular scale damage.
