Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).

Deciphering Solvation Chemistry for Low‐Temperature Lithium‐Ion Battery Electrolytes: Mechanisms, Strategies, and Beyond

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Low‐temperature performance degradation limits lithium‐ion batteries (LIBs) in extreme climates and specialized applications. Electrolytes govern Li+ transport and interfacial reactions, whereas their solvation chemistry controls ionic conductivity, desolvation kinetics, and interphase stability.

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum ( Sciaenops ocellatus ) and Sheepshead Minnow ( Cyprinodon variegatus )

Environmental Toxicology, Volume 41, Issue 11, Page 1167-1178, November 2026.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.
