Advancing the development of lithium-sulfur (Li?S) technology is advantageous for next generation secondary batteries to improve gravimetric and volumetric energy established storage devices. In this regard, a sparingly PS solvating electrolyte based on sulfolane hydrofluoroether known as promising concept enhance density by increasing cycling stability. So far, little about impact carbon poros...

The activity coefficients at infinite dilution, c13, of 55 organic solutes and water in three ionic liquids with the common cation 1-butyl-3-methylimidazolium and the polar anions Cl , [CH3SO3] and [(CH3)2PO4] , were determined by (gas + liquid) chromatography at four temperatures in the range (358.15 to 388.15) K for alcohols and water, and T = (398.15 to 428.15) K for the other organic solute...

The effectiveness of two new supercharging reagents for producing highly charged ions by electrospray ionization (ESI) from aqueous solutions in which proteins have native structures and reactivities were investigated. In aqueous solution, 2-thiophenone and 4-hydroxymethyl-1,3-dioxolan-2-one (HD) at a concentration of 2% by volume can increase the average charge of cytochrome c and myoglobin by...

The separation of aromatic hydrocarbons (benzene, toluene, ethyl benzene and xylenes) from C4 to C10 aliphatic hydrocarbon mixtures is challenging since these hydrocarbons have boiling points in a close range and several combinations form azeotropes. In this work, we investigated the separation of toluene from heptane by extraction with ionic liquids. Several ionic liquids are suitable for extr...

The effects of 12 acids, 4 solvents, and 8 low-volatility additives that increase analyte charging (i.e., superchargers) on the charge state distributions (CSDs) of protein ions in ESI-MS were investigated. We discovered that (i) relatively low concentrations [5% (v/v)] of 1,2-butylene carbonate (and 4-vinyl-1,3-dioxolan-2-one) can be added to ESI solutions to form higher charge states of cytoc...

Highly concentrated Li salt/aprotic solvent solutions are promising electrolytes for next-generation batteries. Understanding the Li+ ion transport process is crucial designing novel battery electrolytes. In this study, we systematically investigated phase behavior, solvate structures, and properties of binary mixtures comprising lithium bis(trifluoromethanesulfonyl)amide (LiTFSA) various sulfo...
