Surface Forces Research Laboratory

We study the physics and physical chemistry of liquid electrolytes and ionic matter. Electrolytes are all around us (oceans) and within us (cellular media) and are of great importance in energy storage technologies (batteries). Yet from a molecular perspective electrolytes are rather special and complex, with many fundamentals still unresolved.  Our current interests include highly concentrated electrolytes, osmolytes, eutectic mixtures, ionic liquids/molten salts -- but we can be tempted to study all interesting liquids! We carry out experiments and analysis to investigate structural, dynamic, thermodynamic, electrochemical, and electrokinetic properties. We have particular expertise in measuring interaction forces using a surface force balance (SFB); this extraordinary technique allows deep insight into bulk and nano-confined materials. Most of our work is fundamental and curiosity-driven, but outcomes help to solve problems and generate greater understanding relevant to a range of applications including energy storage, bio-molecular interactions, and nanomaterials.
