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.

Differential effects of lipid composition on the thermal and functional properties of membrane associated CYP2J2

Protein Science, Volume 35, Issue 7, July 2026.
Abstract CYP2J2 is a membrane‐bound cytochrome P450 that is expressed in cardiomyocytes, where it is known to metabolize arachidonic acid into cardioprotective epoxyeicosatrienoic acids (EETs). It consists of transmembrane domains embedded in the hydrophobic segments of the cell membrane and surrounded by various lipids.

Extraction rates of zinc with ammonium chloride salts of Amberlite LA-2 in a horizontal rectangular channel.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1989
Extraction rates of zinc with ammonium chloride salts of Amberlite LA-2 in hexane were measured in a horizontal rectangular channel. The experimental results were analyzed by considering the processes of diffusion in both solutions, adsorption and desorption to/from the interface and reactions at the interface for the species related as following steps;

N‐Glycosyl Triazoline Glycomimetics via Huisgen Cycloaddition With an Electron‐Deficient Alkene and BF3‐Catalysed Triazoline Fragmentation to Aziridines

European Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
Glycomimetics with triazoline and aziridine groups were synthesised via diastereoselective Huisgen cycloaddition from glycosyl azides. Density functional theory was applied to define the mechanism for BF3 promoted aziridine formation. Triazoline and aziridine derivatives were synthesised by diastereo‐ and regioselective Huisgen cycloaddition of 2,3,4,6‐
