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.

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 ...

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.

Energy Science &Engineering, EarlyView.This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity
