Solid ionic conductors are actively sought for their potential application in electrochemical devices, particularly lithium batteries. We have found high ionic conductivity for a large variety of salts dissolved in the highly polar medium based on the plastic-crystal form of succinonitrile (N[triple bond]C[bond]CH(2)[bond]CH(2)[bond]C[triple bond]N). Its high diffusivity, plasticity and solvati...

Some of organic ammonium salts, namely: 2-((4-carboxyphenyl) carbamoyl) benzoate tetraethylammonium, B1, 4-oxo-4-(pyridin-3-ylamino)-2-butenoate B2, 2-((4-carbamoylphenyl) B3, 4-((4-carbamoylphenyl)amino)-4-oxobutanoate B4, are successfully synthesized as ionic liquids. By spectral techniques FTIR, 1H-NMR and 13C-NMR the structures salts confirmed. The thermal analysis by differential scanning ...

A series of asymmetric viologen bistriflimide salts both short and long alkyl chains were synthesized by the metathesis reaction lithium triflimide salt with respective dibromide in methanol. Their thermotropic liquid crystalline properties determined differential scanning calorimetry, polarizing optical microscopy variable temperature X-ray diffraction techniques. These melt into highly-ordere...

A comprehensive model has been developed for calculating the thermal conductivity of aqueous, nonaqueous, and mixed-solvent electrolyte systems ranging from dilute solutions to fused salts or pure solutes. The model consists of a correlation for calculating the thermal conductivity of solvent mixtures and a method for predicting the effect of electrolyte components. The thermal conductivity of ...

A comprehensive model has been developed for calculating electrical conductivities of aqueous or mixed-solvent electrolyte systems ranging from dilute solutions to fused salts. The model consists of a correlation for calculating ionic conductivities at infinite dilution as a function of solvent composition and a method for predicting the effect of finite electrolyte concentration. The effect of...

1-alkyl-3-methyl-imidazolium (Cn-mim) salts are examples of ionic liquids (ILs).[1] In these salts, the cation is a bulky organic molecule: accordingly, due to factors such as the hindered ion packing and low charge density, the melting point is relatively low compared with conventional inorganic salts. As a consequence, it is possible to synthesise ILs which are liquid at room temperature. The...

The simplest, single-component biological membrane challenges accepted models of macromolecular interactions: lipid lamellar phases swell when immersed in monovalent salt solutions. Moreover, typical of a Hofmeister series, Br salts swell multilayers more than Cl salts, offering an excellent opportunity to investigate long-standing questions of ionic specificity. In accord with earlier measurem...

Amines dissolved in ionic liquids react rapidly with SO(2) to produce new materials. Compounds related to the stepwise conversion of SO(2) to sulfite and sulfate salts have been isolated. Trapping SO(2) in the form of the sulfite anion does not change the oxidation state of sulfur and should maintain the reversibility of the capture system.
