Ionic liquid crystals combine the unique solvent properties of ionic liquids with self-organization found for liquid crystals. We report a detailed analysis of the structure-property relationship of a series of new imidazolium-based liquid crystals with an extended aromatic core. Investigated parameters include length and nature of the tails, the length of the rigid core, the lateral substituti...

Aluminum is the most earth-abundant metal, trivalent, inert in ambient humid air, and has a density approximately four-times that of lithium at room temperature. These attributes make it an attractive material for cost-effective, long-duration storage electrical energy batteries. Scientific discoveries past decade have established secondary Al batteries can be created by paring anode with graph...

Based on the innovation in development of Ionic Liquids (IL), aim present work is to investigate thermophysical properties novel hydrophilic ionic liquid 1-Ethyl-3-Methyl Imidazolium Tetra FluoroBorate (EMIMBF4) and water as binary systems experimentally at various mass fraction temperatures. A Room-Temperature Liquid blended with deionized four different fractions 20%, 15%, 10%, 5% prepare an ...

An investigation of the structure and dynamics of the high-energy ionic liquid, 1-hydroxyethyl-4-amino-1,2,4-triazolium nitrate (HEATN), was undertaken. Both experimental and computational methods were employed to understand the fundamental properties, characteristics, and behavior of HEATN. The charge separation, according to the electrostatic potential derived charges, was assessed. The MP2 (...

New ionic amphiphiles with a hexyl-bridged bis(imidazolium) headgroup; Br(-), BF4(-), or Tf2N(-) anions; and a long n-alkyl tail can form thermotropic bicontinuous cubic liquid crystal phases in neat form and/or lyotropic bicontinuous cubic phases with several non-aqueous solvents or water.

Room temperature ionic liquids, which have unique properties such as a relatively wide electrochemical stability window and negligible vapor pressure, are promising candidates as electrolytes for developing lithium−air batteries with enhanced performance. The local current density, a crucial parameter in determining the performance of lithium−air batteries, is directly proportional to the rate ...

Hydrogen sulfide is one of the most dangerous contaminants in crude oil and natural gas that have to be removed prior to the transfer and refining. In this study, hydrophobic ionic liquid, i.e. 1-ethyl-3-methylimidazolium methylflour, [EMIM] [NTf2], was used as scavenger for the reduction of the H2S. Due to its ionic nature, [EMIM] [NTf2] forms nanoemulsion in crude oil media and hence can diss...

WO3 films were obtained via evaporation-induced self-assembly (EISA) using ionic surfactants such as long-chain ionic liquids 1-hexadecyl-3-methyl imidazolium chloride and bromide (C16mimCl and C16mimBr, respectively) and cetyltrimethylammonium chloride and bromide (CTAC and CTAB, respectively) as additives. Owing to the presence of the ionic surfactants, WO3 films crystallize in a preferred or...

The formation of gas hydrates is a major issue during the operation oil and pipelines, because cause plugging, thereby disrupting normal flows. A solution to inject hydrate inhibitors such as ionic liquids. Contrary classical inhibitors, liquids act both thermodynamic anti-agglomerates. Imidazolium-based have been found efficient for inhibition CO2 CH4 hydrates. For hydrates, N-ethyl-N-methylmo...

In this work the molar enthalpy of formation of the ionic liquid 1-ethyl-3-methylimidazolium dicyanoamide in the gaseous phase [C(2)MIM][N(CN)(2)] was measured by means of combustion calorimetry and enthalpy of vaporization using transpiration. Available, but scarce, primary experimental results on enthalpies of formation of imidazolium based ionic liquids with the cation [C(n)MIM] (where n = 2...
