Strain‐Driven Surface Reconstruction During the Alkaline Oxygen Evolution Reaction: a Model Thin‐Film Study

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Dynamic surface reconstruction critically governs the performance and durability of oxide‐based electrocatalysts for the oxygen evolution reaction (OER), yet controlling this process under operating conditions remains challenging. Here, we demonstrate that lattice strain regulates the extent of surface reconstruction in perovskite oxides by ...

Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

open access: yesAdvanced Materials, EarlyView.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

Surface Passivation of HgTe Nanocrystals Enabling EG/2 Open‐Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection

open access: yesAdvanced Materials, EarlyView.
This article explores how the integration of a thin shell, combined with optimized surface chemistry, enables the design of photodiodes based on short‐wave infrared HgTe nanocrystals. These photodiodes achieve an open‐circuit voltage greater than half the optical bandgap, which drastically reduces dark current. The article also explores the integration

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking

open access: yesAdvanced Materials, EarlyView.
An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

open access: yesAdvanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...
