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 ...

Biomimetic Adaptive Hydrothermal Balance Fabric‐Based Dual‐Interface Solar Evaporator for Efficient and Stable Desalination

open access: yesAdvanced Science, EarlyView.
This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...

Analog Signal Summation for Reinforcement Learning via Simultaneous Light–Voltage Modulation in a Synaptic Device

open access: yesAdvanced Science, EarlyView.
To overcome limitations of conventional AI hardware, a light‐voltage dual‐modulating synaptic (LVDS) transistor using an IGZO/InAs quantum dot hybrid structure is proposed. LVDS transistor enables analog summation for Dueling Deep Q‐Networks by independently modulating memory via optical and electrical stimuli.

Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis

open access: yesAdvanced Science, EarlyView.
A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

Enhanced Thermodynamic Stability of UO22+ Complex Through Structure Preorganization of N3O2‐Pentadentate Planar Ligand for Uranium Harvesting from Seawater

open access: yesAdvanced Science, EarlyView.
Thanks to the appropriate structure preorganization of an N3O2‐pentadentate planar ligand, 2,6‐bis(2‐hydroxyphenylmethylaminomethyl)pyridine (H2saldamp) exhibits the strongest coordination affinity to UO22+ (log βU = 33.60) compared to ligands developed for uranium harvesting from seawater to date, as well as good separability of UO22+ from other metal

A Universal Metal–Flavonoid Coating Strategy: Engineering Biomaterials for Diabetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Construction of metal–flavonoid functionalized coatings on conventional bone repair materials. A one‐pot method is used to directly construct multifunctional metal–flavonoid coatings on the surface of traditional bone repair materials by selecting metal ions with osteogenic/angiogenic properties and flavonoids with reactive oxygen species scavenging ...
