Multi‐Stimuli Responsive Magneto‐Coacervate Droplets for Selective Molecular Enrichment and Programmable Manipulation

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 ...

Oral Prebiotic Polysaccharide Hydrogels Sustaining Colon Antibody Release Alleviate Inflammatory Bowel Disease

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 ...

Kaempferol Attenuates Spaceflight‐Associated Knee Cartilage Degradation by Targeting NOX4‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
We have shown that both simulated and actual spaceflight contribute to cartilage degradation in the knees of mice. Using RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a key factor driving these changes. Additionally, we found that kaempferol, a naturally occurring flavonoid that binds directly to NOX4, reduces ...

Overcoming the Catalytic Bucket Effect in Pt‐based High‐Entropy Nanocages Through Interface Defect and Strain Engineering

Advanced Science, EarlyView.
PtPdNiCuMnAu HENCs exhibit a remarkable half‐wave potential (E1/2) of 0.925 V vs. RHE. The catalyst displays exceptional electrochemical stability, with only a 4 mV negative shift in E1/2 and a mere 5.6% loss in MA after 10, 000 accelerated durability test cycles.
