Web10 Jan 2024 · Thermophysical properties of polar-antiparallel β-sheet crystalline domains of B.mori silk fibroin has been investigated via molecular dynamics (MD) simulations between 300 K and 700 K. In general, the type of interactions determines the character of the thermal expansion in corresponding directions except that the crystalline domains with serine … Web10 Jul 2024 · We envision that the remarkable damping performance of the supramolecular fiber arises from energy dissipative mechanisms provided by a complex structure of “hard” (crystalline) and “soft” (amorphous) phases at the molecular scale (vis. semicrystalline H1 polymer) (Fig. 3I), like in spider silks (29, 31). Although the soft phase is always active, the …
