Observation of Excitonic Instability in a Monolayer Ta2NiSe5 With Strain Disorder

Advanced Science, EarlyView.
Monolayer Ta2${\rm Ta}_2$NiSe5${\rm NiSe}_5$ sustains an excitonic insulating phase up to 190 K, with Raman signatures of gap opening and critical excitonic fluctuations. Thickness‐independent large gap ratios highlight strong exciton‐phonon coupling, while substrate‐induced strain disorder depresses Tc, establishing monolayer Ta2${\rm Ta}_2$NiSe5${\rm

Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor

Advanced Science, EarlyView.
Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

Dual‐Stage Microneedle Patch With Lipid Droplet‐Mediated ‘Capture‐Kill’ and Sustained Release for Enhanced Wound Healing

Advanced Science, EarlyView.
We report a lipid‐droplet‐engineered, gallium‐loaded sonodynamic therapeutic platform (LDTG) incorporated into a bilayer microneedle (MN) patch co‐delivering all‐trans retinoic acid (ATRA), termed LDTG A‐MNs, for synergistic antibacterial therapy and accelerated wound repair.
