Development of Sub‐50 nm Core–Shell Silica Nanoparticles With Controlled In Vivo Behavior for 19F Magnetic Resonance Imaging

Angewandte Chemie, EarlyView.
Ultrasmall PFCE‐loaded silica nanoparticles synthesized through a one‐pot double‐emulsion synthesis method, where rapid silica shell formation kinetically fixes droplet size. The resulting s‐FLAME nanoparticles enable strong 19F MRI signals with enhanced hepatic clearance rate and tumor‐accumulation performance. ABSTRACT 19F magnetic resonance imaging (

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...
