Closed‐Loop Recyclable Solid Polymer Electrolytes via Dynamic Lipoate Cross‐Linking

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
A visible‐light‐driven, closed‐loop recyclable solid polymer electrolyte is built from a bio‐derived lipoate cross‐linker, poly(ethylene glycol) bis(lipoate) (PEG‐LP2), synthesized from α‐lipoic acid. Dynamic disulfide exchange enables efficient DBU‐catalyzed depolymerization and photo‐repolymerization, regenerating membranes that retain high ionic ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, Volume 46, Issue 11, Page 4085-4098, November 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Polymer Brushes Govern Defect‐Selective Oxidative Etching of Penta‐Twinned Gold Nanorods

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Polymer brushes act as active interfacial regulators of oxidative etching, directing it to crystallographic defects. In penta‐twinned gold nanorods, defect–ligand interplay localizes etching to defect regions and induces surface corrugations on the long nanorod sides. This work establishes a framework for programmable nanoengineering of the surfaces of

Mannosylxylarinols A and B, Two New 3,4‐Seco‐ergostane‐type Steroidal Saponins From the Fungus Xylaria necrophora SZSS1‐2‐2

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Two new 3,4‐seco‐ergostane saponins (1–2) and four known compounds were isolated from Xylaria necrophora. Structures were elucidated via spectroscopy, ECD, and computational NMR. Compound 5 selectively inhibited BV2 microglial cells (IC50 = 17.10 µM), while all compounds showed no antimicrobial activity against tested microorganisms. ABSTRACT Two new 3,
