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

Advanced 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

Advanced 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.

Tailored Cationic Visible‐Light‐Active Interfaces for Sustainable, Biodegradable Nanofibers With Dual‐Mode Antimicrobial Activity and Robust Electrostatic Particle Capture

Advanced Materials, EarlyView.
Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

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

Advanced 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

Advanced 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.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.
