Multifunctional Cyclized Polyacrylonitrile (cPAN) as a Coating for Sb-Based Anodes in Sodium-Ion Batteries.

Conversion electrodes, such as antimony (Sb), are high energy density electrode materials for sodium-ion batteries (NIBs). These materials are limited in their performance due to the mechanical instability of these systems resulting from volume expansion of the material during cycling. Stabilizing conversion materials using a conductive polymer binder (CPB) protective layer is an effective way to enhance the performance of these materials.

Dicyanamide Anion Reports on Water Induced Local Structural and Dynamic Heterogeneity in Ionic Liquid Mixtures.

The effects of limited amounts (under 21.6% χ) of water on 1-butyl-3-methylimidazolium tetrafluoroborate (BmimBF) and 1-butyl-3-methylimidazolium dicyanamide (BmimDCA) room-temperature ionic liquid (RTIL) mixtures were characterized by tracking changes in the linear and two-dimensional infrared (2D IR) vibrational features of the dicyanamide anion (DCA). Peak shifts with increasing water suggest the formation of water-associated and nonwater-associated DCA populations.

Off-critical wetting layer divergence at the liquid/vapor interface of binary liquid mixtures.

Surface wetting phenomena impact chemistry, physics, biology, and engineering. The wetting behaviors of partially miscible binary liquid systems are especially complex. Here, we report evidence of universal behavior in the divergence of wetting layer growth at liquid-vapor interfaces of the cyclohexane + aniline, hexane + o-toluidine, and methanol + carbon disulfide systems.
