Alginate-encapsulated ZIF-67 composite gel spheres for enhanced tetracycline removal and fixed-bed application.

The pervasive accumulation of tetracycline (TC) in aquatic ecosystems poses severe ecological and health threats, yet conventional technologies rarely achieve reliable removal under continuous-flow conditions. To overcome the intrinsic brittleness, aggregation and leaching of powdered ZIF-67, this study developed novel alginate-encapsulated MOF composite gel spheres (ALG/ZIF-67) via in-situ crystallization. This simple strategy generates hierarchical pores, anchors Co-N active sites and imparts mechanical robustness without sacrificing adsorption kinetics.

Ultrasound-Assisted and Citric Acid-Guided Creation of ZnO Nanoparticles with Optimized Morphologies to Boost Malachite Green Photocatalysis.

Zinc oxide (ZnO) semiconductors are renowned for their cost-effective synthesis and superior catalytic attributes, making them prominent in environmental remediation applications. This study presents the synthesis of ZnO nanoparticles (NPs) with distinct morphologies, achieved by modulating citric acid concentrations in an ultrasonic-assisted hydrothermal process. The photocatalytic efficacy of these ZnO NPs in degrading malachite green (MG), a persistent environmental pollutant, was thoroughly investigated.

From traditional to modern: Nanotechnology-driven innovation in mycotoxin sensing for Chinese herbal medicines.

Mycotoxin contamination in Chinese herbal medicines (CHMs) is a pressing concern that jeopardizes their quality and safety, despite their widespread therapeutic use. Conventional detection methods are often limited by complexity, cost, and sensitivity, particularly in resource-limited settings. This gap in effective and efficient mycotoxin detection necessitates a comprehensive review that explores innovative solutions to enhance the safety and efficacy of CHMs.
