Advanced Science, EarlyView.Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

Tough and Temperature‐Resistant Material Based on Bombyx mori Silk Fibroin
Advanced Science, EarlyView.We propose a biomimetic “Hydration‐Crystallization Locking” (HCL) strategy inspired by Bombyx mori spinning to enhance silk fibroin (SF) performance in extreme temperatures. A flexible fibroin membrane (FFM) shows high strength, toughness, and shape retention under −196°C and 70°C.
