《Role of image charges in ionic liquid confined between metallic interfaces》 was published in Physical Chemistry Chemical Physics in 2020. These research results belong to Ntim, Samuel; Sulpizi, Marialore. Category: imidazoles-derivatives The article mentions the following:
The peculiar properties of ionic liquids in confinement have not only become essential for energy storage, catalysis and tribol., but still pose fundamental questions. Recently, an anomalous liquid-solid phase transition has been observed in at. force microscopy experiments for 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]), the transition being more pronounced for metallic surfaces. Image charges have been suggested as the key element driving the anomalous freezing. Using atomistic mol. dynamics simulations, we investigate the impact of image charges on structure, dynamics and thermodn. of [BMIM][BF4] confined between gold electrodes. Our results not only unveil a minor role played by the metal polarisation, but also provide a novel description of the interfacial layer. Although no diffuse layer can be defined in terms of the electrostatic potential, long range effects are clearly visible in the dynamical properties up to 10 nm away from the surface, and are expected to influence viscous forces in the experiments In the experiment, the researchers used many compounds, for example, 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Category: imidazoles-derivatives)
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. A multidisciplinary study on lonic liquids is emerging, including chemistry, materials science, chemical engineering, and environmental science. More specifically, some important fundamental viewpoints are now different from the original concepts, as insights into the nature of lonic liquids become deeper. For example, the physicochemical properties of lonic liquids are now recognized as ranging broadly from the oft quoted “nonvolatile, non-flammable, and air and water stable” to those that are distinctly volatile, flammable, and unstable.
