Transparent Ceramic@Sapphire Composites for High‐Power Laser‐Driven Lighting

open access: yesAdvanced Science, EarlyView.
This work introduces an innovative strategy for high‐power laser lighting by integrating a phosphor ceramic layer with a high‐thermal‐conductivity sapphire substrate through a simple high‐temperature sintering process. This approach enhances luminous flux (152–319%) and increases the luminescence saturation threshold (100–233%), making it versatile ...

A Needle‐Like H2S‐Releasing and H2O2 Self‐Replenishing Nanoplatform for Enhanced Chemodynamic Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
The PTA‐SnS2@GOx cascade nanosystem presents a smart paradigm for cancer theranostics, integrating self‐supplied H2S/H2O2‐augmented chemodynamic therapy (CDT) with sensitized immunotherapy. Its needle‐like SnS2 shell enhances tumor‐specific uptake, ensuring biosafety.

Thermo‐Responsive Tri‐State Photonic Crystals

open access: yesAdvanced Science, EarlyView.
Tri‐state photonic crystals combine thermochromic structural color, fluorescence, and afterglow via far‐field absorption tuning, bypassing the efficiency‐lifetime trade‐off of TS‐FRET. This enables dynamic, high‐capacity anti‐counterfeiting with tunable optical states.

An Electrode Design Strategy to Minimize Ferroelectric Imprint Effect

open access: yesAdvanced Science, EarlyView.
A tunable electrode design using La0.7Sr0.3MnO3 enables precise modulation of ferroelectric imprint through oxygen pressure–controlled work function engineering. By applying this strategy to both perovskite and fluorite systems, the built‐in field is effectively suppressed, enabling low‐voltage, high‐endurance ferroelectric devices, including Fe‐FETs ...
