Novel ionic liquid-sulfolane composite electrolytes based on the 1,2,3-triazolium family of ionic liquids were developed for dye-sensitized solar cells. The best performing device exhibited a short-circuit current density of 13.4 mA cm(-2), an open-circuit voltage of 713 mV and a fill factor of 0.65, corresponding to an overall power conversion efficiency (PCE) of 6.3%. In addition, these devic...

Stoichoimetric graphene fluoride monolayers are obtained in a single step by the liquid-phase exfoliation of graphite fluoride with sulfolane. Comparative quantum-mechanical calculations reveal that graphene fluoride is the most thermodynamically stable of five studied hypothetical graphene derivatives; graphane, graphene fluoride, bromide, chloride, and iodide. The graphene fluoride is transfo...

An ethylene carbonate-free electrolyte composed of 1 M lithium bis(fluorosulfonyl) imide (LiFSI) in sulfolane (SL) is studied here for LiNi0.5Mn1.5O4-graphite full-cells. important focus on the evaluation anodic stability SL and passivation layers formed LiNi0.5Mn1.5O4 (LNMO) graphite being analysed along with intermittent current interruption (ICI) technique to observe resistance while cycling...

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...

Sulfolane (C4H8SO2; CAS 126-33-0) is a solvent used for gas treating in a variety of industrial processes. It is known under a variety of synonyms and trade names including bondelane A, 2,3,4,5-tetrahydrothiophene-1,1dioxide, and tetramethylene sulfone. It has a molecular weight of 120.17 g·mol, a density of 1.276 g·cm at 15°C, an aqueous solubility of 1,266,000 mg·L at 20°C, a log Koc of 0.07,...

In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27 (5)-99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packin...

Lithium-metal batteries (LMBs) with high energy densities have aroused intensive interest in electrical storage devices but suffer from the risk of thermal runaway, especially under harsh conditions temperature or abuse. Pursuing intrinsically thermally stable electrolytes higher performance and safety beyond commercial liquid is a major challenge this field. Here we report on unique, highly du...
