Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites

Advanced Science, EarlyView.
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...

Highly Oriented Bio‐Mimetic Hydrogels by Calendering

Advanced Science, EarlyView.
A facile and scalable organogel‐assisted calendering strategy is proposed to prepare bio‐mimetic anisotropic polyvinyl alcohol (PVA) hydrogels. By employing a combination of shearing and annealing during calendering, PVA chains are aligned in the calendering direction, while the compression in thickness facilitates the formation of a nacre‐like ...

Molecular Creep Induced Fatigue Rupture of Fibrin Clots

Advanced Science, EarlyView.
Fibrin networks in thrombi paradoxically exhibit low fatigue resistance despite high fracture energy, as cyclic loading triggers irreversible α‐to‐β transitions in fibrin molecules, causing molecular creep, crack propagation. Multiscale experiments, modeling reveal how nanoscale conformational damage accumulates, linking molecular disorder to ...
