An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

Advanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

Modeling of crack bridging in a unidirectional metal matrix composite [PDF]

The effective fatigue crack driving force and crack opening profiles were determined analytically for fatigue tested unidirectional composite specimens exhibiting fiber bridging. The crack closure pressure due to bridging was modeled using two approaches;

Ion‑Mediated Structural Engineering of Hydrogel Interfaces for Tunable Mechanical and Analyte Diffusion Properties in Electrochemical Biosensors

Advanced Materials, EarlyView.
An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...

Deployable 3D‐Printed Vascular Stent with Surface‐Catalysed Endogenous Nitric Oxide Generation

Advanced Materials, EarlyView.
A deployable 3D‐printed vascular stent was fabricated with surface‐catalyzed endogenous nitric oxide generation, representing a promising new direction for stent development. The stent can be remotely controlled by magnetic force in its compressed state and fully deployed at the target site using an untethered heat source, potentially eliminating the ...

Characterization of Elevated Temperature Fatigue Crack Growth Rates

Superalloys 1984 (Fifth International Symposium), 1984
The applicability of the fracture mechanics parameter K to characterizing elevated temperature fatigue crack growth data has been examined. The extent to which the testing conditions influence the degree of crack tip stress relaxation has been determined by measurement of the crack tip plastic zone size.
