Advanced Science, EarlyView.Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...

Advanced Science, EarlyView.ABSTRACT Coacervate droplets formed via liquid–liquid phase separation offer unique opportunities as microreactors and delivery vehicles due to their ability to selectively concentrate biomolecules and support biochemical reactions. However, their passive nature severely restricts precise spatial and temporal control, posing barriers to practical ...

Bipolar Palladium Membrane Enabling Crossover‐Free Selective Proton Transport
Advanced Science, EarlyView.This study introduces a crossover‐free bipolar palladium membrane that transports protons selectively via reversible Pd/PdHx absorption–desorption and lattice hydrogen diffusion, overcoming the conductivity–selectivity trade‐off of polymer membranes. It enables water‐fed Li‐mediated ammonia synthesis, achieving 51% Faradaic efficiency and stable 12 h ...

Advanced Science, EarlyView.An orally administered prebiotic polysaccharide hydrogel (predaGel) based on inulin and alginate‐dopamine is stable in the stomach, adheres to the intestine, and degrades slowly in the colon. It enables site‐specific delivery of anti‐TNF‐α and anti‐IL‐12/23 antibodies, scavenges reactive oxygen species, and remodels gut microbiota, offering effective ...
