Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

open access: yesAdvanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.

Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

open access: yesAdvanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–

A Biomimetic Solvatochromic Chip With Optimized Chemical Diversity for On‐Site Liquid Identification

open access: yesAdvanced Science, EarlyView.
A compact biomimetic photonic‐gustatory chip uses Hansen‐solubility‐parameter‐guided solvatochromic disks to create distinct color patterns in organic liquids. An optimized four‐disk array distinguishes solvent types, ratios, homologues, isomers, and alcoholic beverages. Coupled with smartphone imaging and deep learning, it identifies 80 liquid classes

Stretchable h‐BN/TPU Fibers for Passive‐Active Dual‐Mode Thermal Management and Wearable Haptic Interfaces

open access: yesAdvanced Science, EarlyView.
Optimized 30 wt.% h‐BN/TPU fibers create a thermal conductivity of 2.08 W·m−1·K−1 while retaining mechanical compliance (422% elongation at break). Woven fabrics reduce surface temperature by 5.7°C under simulated solar irradiation. Glove integration enables localized fingertip heating at 29.55°C·s−1 with a thermal relaxation time of approximately 20 s.

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

open access: yesAdvanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.
