2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

open access: yesAdvanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Hierarchical Collagen Nanofiber Gels Recapitulate a Physiologically Relevant Tumor Stromal Microenvironment

open access: yesAdvanced Healthcare Materials, EarlyView.
The collagen nanofiber (CNF) gel supports cancer cell culture, exhibiting cell morphology and cancer‐related protein expression similar to Matrigel. It offers a higher collagen concentration than commercial gels. Additionally, the CNF gel allows replication of the high elasticity of in vivo cancer tissue by controlling collagen fiber sizes, ranging ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

open access: yesAdvanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.
