Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers

open access: yesAdvanced Functional Materials, EarlyView.
The metal–insulator transition temperature (TMI) is continuously tuned by the systematic change of relative thickness in VO2 and TiO2 films (tVO2/tTiO2${t_{{\mathrm{V}}{{\mathrm{O}}_2}}}/{t_{{\mathrm{Ti}}{{\mathrm{O}}_2}}}$) in freestanding TiO2/VO2/TiO2 tri‐layers.

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

open access: yesAdvanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...
