Collagen breaks at weak sacrificial bonds taming its mechanoradicals [PDF]
Nature Communications, 2023 Collagen is a force-bearing, hierarchical structural protein important to all connective tissue. In tendon collagen, high load even below macroscopic failure level creates mechanoradicals by homolytic bond scission, similar to polymers.

Thermodynamics of Extra-Toughness and Hidden-Length in Polymeric Materials with Sacrificial Bonds
Applied Mechanics, 2022 Sacrificial bonds have been observed in several biological materials and structures and can increase their toughness, i.e., their resistance to fracture.

Journal of the American Chemical Society, 2023 Sacrificial chemical bonds have been used effectively to increase the toughness of elastomers because such bonds dissociate at forces significantly below the fracture limit of the primary load-bearing bonds, thereby dissipating local stress. This approach owes much of its success to the ability to adjust the threshold force at which the sacrificial ...
