CeO2‐Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability

open access: yesAdvanced Science, EarlyView.
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

Field Emission Enhancement in Graphene/Cu Cathodes Through Laser‐Shock‐Induced Modulation of Geometry and Work Function

open access: yesAdvanced Science, EarlyView.
Laser shock microforming converts graphene/Cu foils into flexible cathodes without transfer while modulating their local work function. Lower barriers near protrusion tops and rims coincide with electric field concentration, favoring electron emission.

Multifunctional Vertical Bulk‐Heterojunction Transistors With Amorphous GaOx for Neuromorphic Perception‐to‐Decision

open access: yesAdvanced Science, EarlyView.
A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

Gradient‐Oxidized Bacterial Cellulose for Self‐Sustained Soil Moisture Sensing

open access: yesAdvanced Science, EarlyView.
An asymmetric encapsulated bacterial cellulose device integrates a gradient‐oxidized BC framework with a LiCl‐doped Ecoflex hygroscopic layer, enabling self‐powered soil moisture monitoring through directional ion transport. The device sustains stable hydrovoltaic output, supports deep‐learning humidity classification, and fully biodegrades in soil ...

Evaluating the respective role of individual precipitates on the hydrogen trapping ability and locations of a co-precipitation enameled steel via in situ Scanning Kelvin Probe Force Microscopy

open access: yesPhilosophical Magazine Letters
The fishscaling resistance of enameled steel is closely related to the hydrogen-related behaviour of its constituent phases, in which dispersed co-precipitates are regarded as the most effective hydrogen-trapping sites.

Synthesis Route‐Controlled Atomic Ordering Optimizes Thermoelectric Transport in Bi2SbSe3

open access: yesAdvanced Science, EarlyView.
Atomic ordering modulation enhancing the thermoelectric performance of Bi2SbSe3. The solid‐state synthesis route redistributes Sb atoms between the Bi2Se3 quintuple layers and the Bi bilayers in the BiSe structure, resulting in a more disordered Bi2SbSe3 than the one‐pot synthesized counterpart.

Interface‐Mediated Self‐Rectifying CsCuCl3 Memristors With Tunable Thresholds for Reconfigurable Neuromorphic Computing

open access: yesAdvanced Science, EarlyView.
Interface‐mediated CsCuCl3 memristors achieve self‐rectification and tunable thresholds, enabling selector‐free 8 × 8 arrays with > 105 ON/OFF and > 104 rectification. Supporting dual‐mode neuromorphic computing, negative thresholds preserve low‐light recognition accuracy (91%), while positive thresholds enable sparsity‐aware edge computing.
