Quantifying Ethereal Solvation Effects on Ca2+ Coordination in Well-Dissociated Electrolytes
Through the combination of X-ray absorption fine structure (XAFS) and time-dependent density functional theory (TDDFT), descriptive measures of the local geometry, coordination, and electronic structure of Ca–ethereal complexes provide distinct structural trends depending on the extent of the Ca2+–solvent interaction.

Ion-conducting Thermo-responsive Films Based on Polymer Grafted Cellulose Nanocrystals
Mechanically robust, thermoresponsive, ion-conducting nanocomposite films have been prepared from ionic liquid imbibed poly(2-phenylethyl methacrylate)-grafted cellulose nanocrystals. On account of the lower critical solution temperature (LCST) of the grafted polymer in the ionic liquid, these materials exhibit a conductivity decrease around 60 °C … Read More

Competition of Stacking and Piling Improves Molecular Solubility in Electrolyte
Organic redox-active molecules (redoxmers) are charge carriers in redox flow cells. Since the energy density of a battery fluid is proportional to concentration of active molecules, high molecular solubility is desirable. However, as the redoxmer solutions become crowded, solute-solute interactions become stronger, opposing high solubility. Read More

Greater redoxmer stability through nanoconfinement
Structural diversity of organic redox-active molecules (redoxmers) permits tuning not only solute-electrolyte interactions but also solute-solute interactions in concentrated electrolyte solutions. The 1,4-dimethoxybenzene (DMB) family is an example of such flexibility. We show that DMB molecule 1 forms extended aggregates in concentrated solutions whereas simpler … Read More
