Ionic Liquids

Ionic Liquids

I am interested in investigating the fascinating properties of ionic liquids, in particu­lar their hydrogen bond network and their unique solubility properties. In my group, we study the dissolution of cellulose in ionic liquids. For example, we have established triazolium-based ionic liquids as a novel class of cellulose sol­vents. We also develop force fields for ionic liquids and their mixtures.
