Food Packaging Chemicals and Human Health: Molecular Toxicity, Exposure Pathways, and Regulatory Perspectives
Abstract: Food packaging plays a vital role in preserving food quality, extending shelf life, and ensuring safe transportation. However, increasing evidence indicates that chemicals from packaging materials can migrate into food during processing, storage, and consumption, resulting in chronic human exposure. Several food packaging chemicals, including bisphenols, phthalates, per- and polyfluoroalkyl substances (PFAS), styrene, heavy metals, and non-intentionally added substances (NIAS), have emerged as important xenobiotics due to their potential adverse …

Recent Advances in Crystal Defect Engineering of Semiconductor Photocatalysts for Sustainable Environmental and Energy Applications
Abstract: Semiconductor photocatalysis has emerged as one of the most promising green technologies for addressing environmental pollution and global energy challenges through solar energy utilization. Nevertheless, the practical application of conventional semiconductor photocatalysts is often limited by their narrow visible-light absorption, rapid recombination of photogenerated electron–hole pairs, insufficient active sites, and poor charge-transfer efficiency. Defect engineering has recently attracted significant attention as an effective strategy to overcome these limitations by deliberately …
