Article Synopsis
- Lead halide perovskite shows great promise for wearable technology due to its superior photoelectric properties, but its lead toxicity has limited practical applications.
- An innovative method called lead-rivet enables the in-situ growth of perovskite nanocrystals, stabilizing lead ions through robust S-Pb bonds, which minimizes lead leakage and toxicity.
- The resulting materials exhibit excellent fluorescence, high stability under extreme conditions, and meet WHO standards for safety, suggesting a viable pathway for the use of perovskite in textiles and other applications.
Designing and developing cost-effective, high-performance catalysts for hydrogen evolution reaction (HER) is crucial for advancing hydrogen production technology. Tungsten-based sulfides (WS) exhibit great potential as efficient HER catalysts, however, the activity is limited by the larger energy required for water dissociation under alkaline conditions. Herein, we adopt a top-down strategy to construct heterostructure Co-WS nanofiber catalysts.

Determination of cesium ion in soybean oil is of high importance since the increasing risk from releasing of main component of nuclear waste cesium 137. The complex composition and high viscosity of soybean oil make it necessary to convert it into water phase by nitration before detection, so developing a simple, accurate and sensitive method for on-site sensing of Cs in soybean oil is still a big challenge. In this work, we report a traffic light-type ratiometric fluorescence strategy for the visual sensing of Cs in soybean oil based on dimensional regulation of two dimensional (PEA)PbI perovskite nanosheets (NSs).

- Enhanced electrochemiluminescence (ECL) focuses on achieving higher sensitivity and better detection limits using core-shell nanostructures that leverage unique surface plasmon resonance (SPR) for stronger electromagnetic fields.
- Current structural designs face challenges due to the electrocatalytic activity of the metal core and the effects from the shell, which can interfere with SPR's contribution to ECL signals; thus, shell-isolated nanoparticles (SHINs) are developed to eliminate these interferences.
- Through precise control of shell thickness and ECL platform design, researchers achieved a significant enhancement of ECL signals (up to ≈250-fold), particularly with a monolayer SHINs setup, facilitating advanced sensing
