2020-8-19The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water aqueous solutions and other hydrogen-bonded liquids – Lubricants polymer solutions and 1 Introduction Ionic liquids (ILs) which are liquids at room temperature and composed of anions and cations have been extensively studied in potential lubrication applications since 2001 [] In the first decades a great deal of work reported ILs as lubricants rather than additives due to their high polarity and poor solubility in traditional hydrocarbon-based lubricants [ ]

A Review of Ionic Liquids Their Limits and Applications

Since environmental pollution caused by chemical and energy industries has increased for several decades there is a social expectation that scientists and engineers try to design sustainable chemical processes to generate less hazardous materials and more environmentally friendly sources of energy production In this review the roles of Ionic Liquids (ILs) and IL based solvent systems as
