Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

On Oxalyl Halide Isothiocyanates Part I: Syntheses and Isomerism

European Journal of Inorganic Chemistry, EarlyView.
Oxalyl halide isothiocyanates can be prepared from oxalyl halide with one equivalent of NH4SCN in liquid SO2. While oxalyl bromide isothiocyanate can be isolated as a liquid, the respective chloride compound readily undergoes isomerization under formation of a thiazole ring, which is obtained as a solid.

A Hoveyda–Grubbs‐Type Olefin Metathesis Catalyst Bearing a Fluorinated Unsymmetrical NHC Ligand

European Journal of Inorganic Chemistry, EarlyView.
A fluorinated unsymmetrical NHC ruthenium complex was synthesised and employed as a catalyst for olefin metathesis reactions. The modification of the steric and electronic properties of the NHC ligand through the introduction of fluorine substituents results in improved activity but lower selectivity compared to the analogous non‐fluorinated NHC ...

Validated RP‐HPLC–UV Method for the Quantitative Analysis and Stability Evaluation of Amoxicillin in Paediatric Gummy Tablets

ELECTROPHORESIS, EarlyView.
A validated RP‐HPLC–UV method was successfully applied for amoxicillin determination in gummy tablets. The method is useful for an accurate amoxicillin content determination in paediatric gummies and was applied to study the stability profile of the drug, evaluated over 6 months under storage conditions.

Phosphate and fluoride removal options for Hanford high‐level waste sludge processing

Environmental Progress &Sustainable Energy, EarlyView.
Abstract High‐phosphate and high‐fluoride sludges represent some of the most challenging waste streams within the Hanford High‐Level Waste (HLW) inventory due to solubility constraints, impacts on glass loading, and corrosion risks during vitrification.
