What is it about?
This work addresses the importance of entropic factors in the behaviour of deep eutectic solvents (DES). The topic is explored through a "computational spectroscopy" approach, combining inelastic neutron scattering spectroscopy and quantum chemical DFT calculations (discrete and periodic).

Why is it important?
In general, most studies on DES focus on enthalpic factors, i.e., on the newly established intermolecular interactions among the mixture components while the influence of entropic changes remains unclear. Understanding the role of entropic factors is crucial for designing and optimizing DES with desired properties. This work clearly evidences the importance of entropic factors in deep eutectic behavior.
Perspectives
I hope this article will inspire further research into the intricate interplay between enthalpic and entropic factors in DES, leading to the development of novel and sustainable materials.
