Title: " On the use of ionic liquids to tune crystallization: From inorganic to protein crystals"
Speaker: Magdalena Kowacz
From: Molecular Thermodynamics Laboratory
Abstract:
Aqueous solutions of ionic liquids (ILs) have been used as crystallization media for inorganic materials and model proteins. The ordering of the ILs into a Hofmeister-like series and their effect on the kinetics and mechanism of crystal nucleation and growth have been explained. Particular effects of the ILs on the crystal morphology development have been interpreted from the perspective of the ability of the ILs to form nanostructured networks in aqueous solution. Some characteristics of the IL´s ions determine also the mutual tendency of the IL cation and anion to associate or stay apart in solution and their partitioning to the interfaces (air/water, solute/water).
The tunable nature of the ionic liquids makes their application in the crystallization strategies very promising once the relationship between particular properties of these liquid salts and crystallization phenomena are recognized.
