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

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
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 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
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 ...

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 ...

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...
