How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Micro‐Strain Responsive Near‐Infrared Mechanoluminescence for Potential Nondestructive Artificial Joint Stress Imaging

Advanced Materials, EarlyView.
In situ and real‐time stress sensing during total knee replacement procedure is expected to be realized based on near‐infrared mechanoluminescent phosphor of Sr3Sn1.98Sb0.02O6.99, which has the lowest strain sensitivity as low as 50 µst. Abstract Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the ...
