Atmospheric Chemistry of CFH2CH2CH2CFH2: Kinetics and Mechanism of Reactions With Cl Atoms and OH Radicals

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 396-406, July 2026.
ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(

Basics and Perspectives of Visible and Near‐UV Light‐Induced Defluorination of Perfluoroalkylsubstances by Semiconductor Nanocrystals

ChemPhotoChem, Volume 10, Issue 6, June 2026.
This review highlights recent advances in the light‐driven destruction of persistent per‐ and polyfluoroalkyl substances (PFASs) using semiconductor nanocrystals. By exploiting nonlinear photophysical and photochemical processes, these nanomaterials harness energy‐efficient visible and near‐UV light‐emitting diodes (LEDs) to drive extreme reduction ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Freshwater ecotoxicity characterization factors for PFASs

Integrated Environmental Assessment and Management
Abstract This research aims to address the data gaps in freshwater ecotoxicological characterization factors (CFs) for per- and polyfluoroalkyl substances (PFASs). These CFs are essential for incorporating the ecotoxicity impacts of PFAS emissions into life cycle assessments (LCAs).

Concentrations and exposure risks of per- and polyfluoroalkyl substances in human milk from Southern China during the first 400 days of lactation

Ecotoxicology and Environmental Safety
Per- and polyfluoroalkyl substances (PFASs) pose significant health risks, particularly for infants who are highly susceptible during early life. Although several studies have reported PFASs concentrations and exposure risks in human milk in China, they ...
