A Wood Plasticine With Controlled Phase‐Change Behavior and Malleability for Energy‐Closed‐Loop and Conformally Adaptive Thermal Management

Advanced Science, EarlyView.
A photothermal wood plasticine exhibiting controlled phase‐change behavior and malleable property is developed. The developed wood plasticine can provide all‐day, on‐demand, and low‐loss solar heating for geometrically diverse objects, including thermoelectric generator, human body, and battery, through its controlled crystallization‐melting ...

Principle of local symmetry in mixed-mode fracture

Communications Physics
When brittle materials are subjected to uniaxial tensile stress, we observe planar crack propagation perpendicular to the loading direction. However, when additionally subjected to an out-of-plane shear stress, the crack tip/front deviates, leading to ...

Toward Flexible Printed Electronics: A Spider‐Silk‐Inspired, Strong and Tough Thermoplastic Polyamide Elastomer

Advanced Science, EarlyView.
Inspired by spider silk, a bio‐inspired polyamide elastomer with a dynamic physical cross‐linking network is developed. Mimicking the rigid β‐sheet crystals and sacrificial hydrogen bonds of silk, the material achieves an exceptional balance of strength and toughness.

Finite fracture mechanics fracture criterion for free edge delamination [PDF]

The interlaminar stresses at the dissimilar interface near the free edges of the composite laminates are weakly singular due to the material mismatch. These stresses can induce delamination between the dissimilar plies. The free edge delamination is investigated in the present study in the framework of Finite Fracture Mechanics. Dimensional analysis is

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.
