Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

Advanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

Formation‐Stage Interfacial Regulation of δ‐MnO2 Enables Stable and Reversible Aqueous Zn‐Ion Storage

Advanced Science, EarlyView.
Precursor‐embedded Fe regulates the nucleation and growth of δ‐MnO2, enabling a more accessible and stable Zn‐storage interface with accelerated kinetics and suppressed Mn dissolution, while preserving the intrinsic Mn redox chemistry. ABSTRACT Layered δ‐MnO2 is a promising cathode for aqueous zinc‐ion batteries, yet its practical application remains ...

Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

Advanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.

Membrane‐Targeted Nanoparticles for Neuronal Photomodulation

Advanced Science, EarlyView.
Immobilizing gold nanoparticles on the neural interface using a bioorthogonal approach generates localized heat upon exposure to near‐infrared light, temporarily inhibiting primary neuronal activity without damaging the cells. This precise placement and retention of nanoparticles at the cell membrane expand the strategies for non‐invasive neural ...
