About this Research Topic
Ionic fluids, such as electrolyte solutions, room-temperature ionic liquids, molten salts, polyelectrolytes, surfactants, and others have garnered considerable attention from researchers and chemical engineers due to their diverse applications. These applications span various fields, including batteries, fuel cells, supercapacitors, lipid membranes, ion exchange resins, and others. In all of these examples, the behavior of ionic fluids is greatly influenced by their interaction with charged surfaces, such as membranes, macromolecules, colloids, or electrode surfaces, or when they are confined within electrified nanopores. Consequently, these systems exhibit strong inhomogeneity. To fully understand and describe the properties of ionic fluids, researchers have employed sophisticated theoretical methods. These methods include molecular dynamics simulations, classical density functional theory (DFT), mean-field theory, and even cutting-edge techniques like machine learning and artificial intelligence. By utilizing these theoretical approaches, researchers can gain valuable insights into the thermodynamic, structural, and transport properties of inhomogeneous ionic fluids. These theoretical methods are invaluable in expanding our knowledge of ionic fluids and their behavior in complex environments. They provide a deeper understanding of the intricate interplay between the ions and the surrounding surfaces, helping to optimize their use in various technological applications.
