Liquid-liquid two-phase systems formed by a hydrophobic ionic liquid and water find several useful ways of application in analytical chemistry. One of the most important properties of such two-phase systems is the mutual solubility of the IL and water. Recent advancements on this subject have been reviewed. The solubility of ionic liquids in water is related to the standard Gibbs energies of th...

Application of gel polymer electrolytes (GPE) in lithium-ion polymer batteries can address many shortcomings associated with liquid electrolyte lithium-ion batteries. Due to their physical structure, GPEs exhibit lower ion conductivity compared to their liquid counterparts. In this work, we have investigated and report improved ion conductivity in GPEs doped with ionic liquid. Samples containin...

In this study, the phase diagram and thermodynamic properties of Ti-O system up to 30 mole percent of oxygen was calculated with Calphad method. In this range of oxygen, Ti-O system includes αTi, βTi and liquid phases. αTi and βTi were modeled by “sublattice” model and the model of liquid phase was modeled by “ionic liquid”. Gibbs energy parameters ...
