From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

open access: yesAdvanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

open access: yesAdvanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

pH‐Responsive Synthetic Cells for Programmable In Situ Protein Synthesis and Release

open access: yesAdvanced Materials, EarlyView.
A synthetic cell is engineered to convert environmental acidification into nucleic acid signaling that activates protein synthesis. By coupling proton‐channel sensing, pH‐responsive DNA transduction, and toehold‐regulated translation, the platform enables acid‐triggered protein production within hydrogel‐embedded synthetic cells.

A Coaxial Bioprinted Hydrogel With Semipermeable Sheath and Pro‐Chondrogenic Core for Articular Cartilage Repair

open access: yesAdvanced Materials, EarlyView.
A sheath‐core biomimetic hydrogel is engineered with a compartmentalized yet integrated architecture for synergistic multifunctionality. Its stiff, semipermeable sheath mimics the ECM's load‐bearing and protective roles, encapsulating a soft core that provides a pro‐chondrogenic microenvironment similar to the PCM.

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

open access: yesAdvanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

open access: yesAdvanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...
