Thermodynamic Transitions and Dynamics in Model Systems of Deep Eutectic Solvents

POSTER

Abstract

The impact of composition on the thermodynamic transitions and dynamics in model systems of deep eutectic mixtures is investigated by broadband dielectric spectroscopy and differential scanning spectroscopy, complemented by NMR and vibrational spectroscopy. It is found that non-eutectic compositions exhibit rich phase behavior characterized by solidus and liquidus transitions in addition to the melting and/or glass transitions found in their eutectic counterparts. The role of structural heterogeneity in determining dynamics in deep eutectic mixtures will be discussed within the framework of recent models of the glass transition.
