Tough and Temperature‐Resistant Material Based on Bombyx mori Silk Fibroin

open access: yesAdvanced 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.

Gravity‐Tolerant In‐Flight 3D Bioprinting Enabled by Stereolithography for Space Tissue Engineering

open access: yesAdvanced Science, EarlyView.
A flight‐compliant, closed stereolithographic 3D bioprinting system enables robust fabrication of acellular and cell‐laden hydrogel constructs under varying gravitational conditions, including microgravity and hypergravity phases. Printed structures retain dimensional fidelity and high‐resolution features, while cell viability remains high ...

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

open access: yesAdvanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...
