New High-Entropy Nitride Unlocks Sustainable Water Purification
This research focuses on the development and structural understanding of a novel material, CrFeCoNiZn high-entropy metal nitride, a single-phase nitride composed of five metallic elements with an anti-perovskite crystal structure. The material exhibits excellent thermal stability due to the high configurational entropy arising from its multi-component composition. It also possesses intriguing properties, including magnetic responsiveness …

Sustainable Approach to Selective Lithium Recovery
This work develops a deep eutectic solvent (DES)-functionalized activated carbon as a selective adsorbent for recovering lithium from complex solutions generated during lithium-ion battery recycling. The material demonstrates high lithium selectivity over transition metals, excellent reusability, and effective performance in real leachates from spent NMC cathodes. This approach offers an efficient and sustainable strategy for …

Rapid and Reliable Method for Detecting Nanoplastics in Water
Nanoplastics are extremely small plastic particles, hundreds of times smaller than the diameter of a human hair. They are considered an emerging contaminant that can pollute natural water sources. Detecting particles at this scale remains a major analytical challenge because of their tiny size, low concentrations, and interference from other substances present in water. This …

Laser Fabrication of Bismuth Nanoparticles-Modified Laser Induced Graphene of Lead and Cadmium Sensing
In this study, a hexagonal bismuth nanoparticle (BiNPs)-modified laser-induced graphene (LIG) electrode was fabricated using a simple CO₂ laser process. The resulting portable sensor enables sensitive detection of toxic heavy metals, including cadmium (Cd²⁺) and lead (Pb²⁺). Key findings:• Simple and scalable fabrication of BiNPs/LIG electrodes by laser writing• Sensitive detection of Cd²⁺ and Pb²⁺ …
