Interfacially Coupled and Synergistic Effect of Ag/Co3O4‐C Nanocomposites for Enhanced Oxygen Reduction (ORR) and Evolution (OER) Reaction

open access: yesAdvanced Science, EarlyView.
Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...

Advancing Precision Nutrition Through Multimodal Data and Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Individual responses to food vary dramatically, challenging traditional dietary advice. This review explores how the unique genetic makeup, gut microbiome, and brain activity shape host metabolic health. We examine how artificial intelligence integrates these multimodal data to predict individualized dietary needs, moving beyond one‐size‐fits‐all ...

Electronic Interaction at Cu–O–Ni Heterointerface Promotes Electrocatalytic Nitrate Reduction to Ammonia and Zinc‐Nitrate Battery

open access: yesAdvanced Science, EarlyView.
The strong Cu–O–Ni electronic interaction in the heterostructured catalyst can enhance the effective adsorption of NO3− and accelerate the in situ hydrolysis dissociation of the hydrogenation step. The Zn‐NO3 hybrid battery assembled with this catalyst achieves an open‐circuit voltage of 1.45 V, a peak power density of 6.47 mW cm−2, and can ...

Cation‐Driven Valence Change Mechanism in 2D AgCrS2 for Ultralow‐Power and Reliable Memristors

open access: yesAdvanced Science, EarlyView.
A 2D AgCrS2 volatile memristor is shown to switch via a cation‐driven valence change mechanism, where Ag+ reversibly intercalates into tetrahedral vacancies between CrS2 layers to form a conductive Ag2CrS2 pathway without elemental Ag metallization. The device exhibits 0.2 V switching, nA‐compliance power down to 200 pW, and endurance beyond 3 × 105 ...

Lattice‐Interface Dual Engineering Unlocking Quasi‐Zero‐Strain and High‐Rate Zinc‐Ion Storage in Polyanionic Cathode

open access: yesAdvanced Science, EarlyView.
Li‐doped Na3V2O2(PO4)2F nanoparticles coated with N‐doped carbon are designed to improve their electronic conductivity. The co‐modification of Li doping and carbon coating improves structural integrity, increases electronic conductivity, lowers the Zn2+ migration barrier, and elevates the average Zn2+ diffusion coefficient, thereby leading to superior ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

open access: yesAdvanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...
