The Cover Feature illustrates the form of achievement of organized models to predict and interpret the viscosity of ionic liquids and their mixtures. The picture starts with non‐organized atoms and components of systems, that with the aid of Chemo‐informatic tools permits to find a straightforward relationship between structure and the viscosity.
