Summary: Room temperature ionic liquids (RTILs) have unique properties, including the ability to support induced free charge density gradient. When diluted, RTILs form micelle-like structures and show compositional non-uniformity. In this study, we investigated the dilution of two imidazolium RTILs with polar aprotic solvents and found that the properties depend on the RTIL anion. Evidence of aggregated domains in the non-affected regions of RTILs was observed, and the domain size increased with increasing dilution.

Summary: The complex behavior of extractants in ionic liquids has been studied through theoretical calculations and simulations, revealing that ion pairs are favored over separated ions and the interaction with the extractant is primarily driven by electrostatic forces. The concentration of the extractant greatly influences the local structures and interactions.

Summary: This study involved the determination of physical parameters and properties of [Bmim][PF6] / N-methylpyrrolidone and their mixtures at various compositions and temperatures. The results indicated strong intermolecular interactions, which increased with temperature. The findings were supported by the Prigogine-Flory-Patterson theory and IR spectra.

Summary: This study evaluated the intermolecular interactions between ionic liquids and acetic acid, propionic acid in binary mixtures, discussing the variations of thermodynamic properties with mole fraction and temperature, as well as the impact of IL anion and alkyl length on properties. The experimental results were used to compute thermodynamic properties and were confirmed through FTIR spectra of pure components and binary mixtures at equimolar compositions.

Summary: The volumetric properties of ionic liquid, propane-1,2-diol, and their binary mixtures were studied. The results showed that the introduction of the ionic liquid disrupted the intermolecular hydrogen bonds in the propane-1,2-diol system, leading to changes in molecular-level interactions. These interactions play a significant role in determining the thermodynamic properties of the binary mixtures.

Summary: Glycerol exhibits symmetrical conformations with different ratios of gt, gg, and tg in water, favoring the symmetric conformers with the 1,2,3-triol groups in gauche/gauche geometry. However, the conformational equilibrium of glycerol shifts towards non-symmetric conformers when the solvent is changed to DMSO-d(6) or DMF-d(7).

Summary: The study investigates the impact of lithium ions on the structure and dynamics of ionic liquids, specifically monocationic ILs and dicationic ILs. The addition of lithium ions significantly alters the microscopic behavior of the ILs, especially in the apolar regions. This research provides insights into how lithium ions influence the nanostructural organization of ILs and highlights their potential as electrolytes in battery applications.

Summary: In this study, the physical properties of 1-butyl-3-methylimidazolium tetrafluoroborate and Benzonitrile binary mixture were measured at different temperatures and atmospheric pressure. Various excess parameters were calculated and the impact of positive or negative deviations on molecular interactions in these mixtures was analyzed. The applicability of the Prigogine-Flory-Patterson theory in predicting values was also assessed.
