Kota Usui, Johannes Hunger, and Mischa Bonn have published together with Marialore Sulpizi a paper on Dynamical heterogeneities of rotational motion in room temperature ionic liquids evidenced by molecular dynamics simulations in the Journal of Chemical Physics.[more]
The research in the group is centred around the dynamics of liquids with a particular focus on the dynamics of ionic and hydrogen-bonded interactions in the liquid phase. To study interactions in the liquid phase we use a combination of spectroscopic methods – predominantly femtosecond infrared and dielectric relaxation spectroscopy complemented by nuclear magnetic resonance spectroscopy and computational methods. Current research themes range from the characterization of the fundamentals of liquids (e.g. hydrogen-bond dynamics in pure water, ionic interactions in ionic liquids, etc.) to application of such knowledge on ionic and hydrogen-bonding interactions in technological processes (e.g. catalysis, cellulose processing, waste treatment, etc.).
