Strong, Recyclable, Bio‐Based Vitrimers by Tailored Rigid‐Flexible Structures for Advanced Carbon Fiber‐Reinforced Polymers

open access: yesAdvanced Science, EarlyView.
A sustainable high‐performance epoxy vitrimer (F9T1) was developed via a rigid‐flexible integrated design using rigid and flexible bio‐based epoxy monomers. F9T1 features superior mechanical property, char‐forming ability, fire safety, chemical degradability and recyclability due to its rigid‐flexible network with abundant dynamic disulfide and ester ...

Integrative Multi‐Omics Analysis Uncovers Immunological Phenotypes Predictive of Combinatorial Immunotherapy Response in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Current understanding of gastric cancer immunity remains inadequate, leading to suboptimal immunotherapy outcomes. This study introduces a novel tumor immune microenvironment classification system (Inflamed, Desert, and Excluded), advancing traditional histopathological or molecular subtyping toward a functional immunological framework.

AI‐Directed 3D Printing of Hierarchical Polyurethane Foams

open access: yesAdvanced Science, EarlyView.
Digitally guided direct ink writing, combined with AI‐generated design, enables the fabrication of hierarchical polyurethane foams with tunable multiscale porosity. This approach produces architected foams featuring interconnected open‐cell networks and tailored mechanical properties, advancing the development of adaptive, high‐performance materials ...

Systematic Benchmarking of a Noise‐Tolerant Conductive Hydrogel Electrode for Epidermal Bioelectronics

open access: yesAdvanced Science, EarlyView.
General schematic of the approach. Abstract Conventional Silver/Silver Chloride (Ag/AgCl) electrodes remain the clinical standard for electrophysiological monitoring but are hindered by poor skin conformity, mechanical rigidity, and signal degradation, particularly under motion or sweat.
