Published: Jan. 1, 2025

Increasing numbers of emerging contaminants (ECs) detected in water environments require a detailed understanding these chemicals’ fate, distribution, transport, and risk aquatic ecosystems. Modeling is useful approach for determining ECs’ characteristics their behaviors environments. This article proposes systematic taxonomy EC models addresses gaps the comprehensive analysis applications. The reviewed include conventional quality models, multimedia fugacity machine learning (ML) models. Conventional have higher prediction accuracy spatial resolution; nevertheless, they are limited functionality can only be used to predict contaminant concentrations Fugacity excellent at depicting how travel between different environmental media, but cannot directly analyze variations parts same media because model assumes that constant within compartment. Compared other ML applied more scenarios, such as identification assessments, rather than being confined concentrations. In recent years, with rapid development artificial intelligence, surpassed becoming one newest hotspots study ECs. primary challenge faced by outcomes difficult interpret understand, this influences practical value an some extent.

Mechanistic insights into the enhanced photocatalytic efficiency of MoS₂-tuned DyFeO₃ heterojunction for pollutants degradation

Nanoscale, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 1, 2025

In this study, DyFeO3-MoS2 heterojunction nanocomposites were synthesized by integrating porous DyFeO3 nanoparticles (an n-type semiconductor) with MoS2 nanosheets (a p-type semiconductor). The resulting p-n substantially improved the photocatalytic efficiency for degrading methylene blue (MB) and levofloxacin (LFX).
