Sorption of Pyrene and Fluoranthene onto Common Microplastics Under Freshwater Conditions

Microplastics
Microplastics (MPs) are recognised as emerging vectors for hydrophobic organic contaminants in aquatic environments due to their relatively large surface area and the diversity of their polymer chemistries compositions.

Deciphering intramolecular charge transfer in fluoranthene derivatives

An intramolecular charge transfer (ICT) state evolves via excited state structural change and solvent reorganization, where the charge distribution in the excited state is markedly different from that in the ground state.

A Convolutional Neural Network and Transfer Learning Approach for Accelerated Quantitative Mass Spectrometry Imaging

Journal of Mass Spectrometry, Volume 61, Issue 6, June 2026.
ABSTRACT This research presents a novel approach to accelerate quantitative mass spectrometry imaging (qMSI) measurements using convolutional neural networks (CNNs) with a transfer learning approach. Current methods are time consuming, require numerous specific steps that allow for the introduction of error, and involve meticulous data analysis.

Fluoranthene degradation in a persulfate system activated by sulfidated nano zero-valent iron (S-nZVI): performance and mechanisms

Water Science and Technology
Fluoranthene (FLT) has received mounting focus due to its hazardous properties and frequent occurrence in groundwater. In this study, sulfidated nano zero-valent iron (S-nZVI) was selected as an efficient catalyst for activating persulfate (PS) to ...
