Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

open access: yesAdvanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

High‐Speed and Scalable Wet Spinning of Graphene/Liquid Crystalline Elastomer Composite Filaments

open access: yesAdvanced Functional Materials, EarlyView.
Polydomain filaments from graphene/liquid crystalline elastomer (LCE) composites are scalably‐manufactured by wet spinning across a wide range of diameters (≈137–1128 µm) at a speed up to 4500 m h−1 through a double diffusion coagulation mechanism, enabling fast actuation and optimized mechanical performance for broad applications.

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

open access: yesAdvanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.
