Engineering Strain‐Stiffening Granular Hydrogels for 3D‐Printed Tissue‐Mimicry
A 3D‐printable strain‐stiffening double‐network granular hydrogel (SDGH) enables independent, region‐specific tuning of toe (EToe) and heel (EHeel) moduli through control of microgel packing and network composition. This platform replicates tissue‐like nonlinear mechanics and allows fabrication of high‐fidelity, multilayered aortic valves with ...

Flexible neutral Zn‐air batteries achieving a remarkable 3000‐cycle lifespan and withstanding 1000 bending cycles are reported. This performance is realized by employing a 3D physically cross‐linked neutral hydrogel electrolyte that integrates high adhesion, self‐healing, O2 permeability, and CO2 tolerance to resolve critical stability challenges ...

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
