In Situ Reconstructed Crystalline–Amorphous CuNi Nanotubes Unifying Activity and Stability for Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Controlled electrochemical reconstruction creates a crystalline–amorphous CuNi nanotube that unifies catalytic activity and durability for alkaline oxygen evolution. The conductive metallic core and active amorphous oxide shell work synergistically to deliver low overpotential and exceptional stability exceeding 1000 h, offering a new strategy for ...

Biomimetic Gradient Hydrogels Regulate Osteochondral Regeneration Microenvironment Remodeling via Spatiotemporal Programming Engineering

open access: yesAdvanced Science, EarlyView.
Electric field‑driven continuous gradient hydrogel GHZF4 achieves spatiotemporal growth factor release, modulates immune microenvironment, angiogenesis and osteochondral differentiation. It realizes cell‑free functional osteochondral repair in rat/rabbit models, offering a promising biomimetic strategy for gradient tissue regeneration.

Promoting Electroreduction CO2 to Multi‐Carbon Products by Tailoring the *H Availability With Optimized Interfacial H2O Configuration

open access: yesAdvanced Science, EarlyView.
A catalysis system with adjustable interfacial H2O configuration was conducted by introducing ionomer into Cu. The increasing proportion of K+‐H2O can enhance the dissociation of H2O and improve the generation ability of *H, and the increasing proportion of 4‐HB‐H2O can accelerate the transfer speed of *H to *CO intermediates with the aid of strong ...

EphB1‐Mediated Transient Blood‐Brain Barrier Opening Facilitates a Ferritin‐Based Nanotherapeutic for Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
We constructed a brain‐targeted AFn‐DPZ nanodrug delivery system and identified EphB1 as its receptor on the blood‐brain barrier (BBB). This system facilitates drug transport across the BBB and thereby ameliorates cognitive impairment in Alzheimer's disease.
