Li,Dechang,and Baohua Ji.2014.“Predicted Rupture Force of a Single Molecular Bond Becomes Rate Independent at Ultralow Loading Rates.”Physical Review Letters 112(7):078302.doi:10.1103/PhysRevLett.112.078302. 5)New strengthening mechanism of ultralong silkβ‑Sheet Nanocrystallites.We found that multiple interface microcracks nucleate and stack at the interface,dividing the interchain interface into small segments,by which the silk protein can achieve a high strength even with the ultralong chains.This is a new strategy of microstructure design of soft matter that could avoid the“larger is weaker”fate due to the increase of the chain length.
