In Situ Construction of Cu+‐Ov‐Ce3+ Sites on CeO2 for Efficient NH3 Oxidation

Advanced Science, EarlyView.
An advanced CeCuOx nanorod catalyst is developed via in situ hydrothermal synthesis, and it exhibits remarkable NH3‐SCO activity, N2 selectivity, and stability. The addition of Cu induces the formation of abundant Cu+‐Ov‐Ce3+ active sites on CeO2 and switch the primary intermediate species of NH3 oxidation from bidentate nitrate species to monodentate ...

Electric Field‐Stimulated Autofluorescence for In Situ 3D Characterization of Polymer Defects

Advanced Science, EarlyView.
Moderate electric fields induce intrinsic autofluorescence at microscale defects within diverse polymers under laser excitation. Combined with confocal microscopy, this probe‐free method enables real‐time, submicron‐resolution 3D imaging of voids, fillers, and electrical trees before irreversible damage occurs.

High‐Temperature Single‐Photon Emission From Covalently Functionalized van der Waals Heterostructures

Advanced Science, EarlyView.
Covalent diazonium functionalization of graphite‐WSe2 heterostructures produces high‐purity single‐photon emission from WSe2 at T = 90 K, far above the typical T = 10 K limit. The chemical modification reshapes graphite's electronic structure and couples to WSe2 midgap states, stabilizing quantum emitters at elevated temperatures and opening pathways ...

Controllable Charge Storability in InP/ZnSe Core/Shell Quantum Dots toward Bioinspired Optical Synaptic Application

Advanced Science, EarlyView.
A field‐effect transistor incorporating type‐I InP/ZnSe core–shell quantum dots demonstrates light‐ and gate‐tunable synaptic plasticity. By leveraging field‐assisted photoinduced charge trapping, the device emulates essential neuromorphic functions, including paired‐pulse facilitation, memory consolidation, and classical conditioning.
