Surface Plasmon Enhanced Photoluminescence of Carbon Dots Formed In Situ on Silver Gratings

Advanced Science, EarlyView.
Carbon emitters formed in situ on a silver grating via plasmonic catalysis yield enhanced spontaneous emission by preferential radiative decay into surface plasmons. Enhancement manifests as emission exhibiting characteristics of coherence (polarization, directionality), and accelerated lifetimes of ∼30 ps, yielding Purcell factors of ∼70.

Tuning Li+ and Na+ Functionality in Renewable Carbon Electroactive Material Through Site‐Specific Nanostructural Disorder

Advanced Science, EarlyView.
This study presents a selective thermal transformation of polycarbonate into hybrid carbon materials. The structured carbon enhances electrochemical performance, particularly in lithium‐ion systems. Investigations reveal improved bimetallic ion diffusivity through the hybrid microstructure, contributing to excellent charge kinetics.

Scalable Electrochemical Concrete Fabrication and Closed‐Loop Recycling

Advanced Science, EarlyView.
The electrochemical‐driven recycling strategy establishes a reversible concrete material flow by extracting Ca, Si, Al, and Fe from concrete waste and regenerating functional feedstocks. These reversed products are reassembled into new concrete, which re‐enters service and ultimately returns to waste, enabling a closed‐loop, waste‐origin, and low ...

High‐Order Nonlinear Photonic Crystal with Ordered Structures for Giant Enhancement of Frequency Tripling

Advanced Science, EarlyView.
A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...
