The Entropy of Deep Eutectic Solvent Formation [PDF]

open access: yesEntropy, 2018
The standard entropies S298°E of deep eutectic solvents (DESs), which are liquid binary mixtures of a hydrogen bond acceptor component and a hydrogen bod donor one, are calculated from their molecular volumes, derived from their densities or crystal ...

Deep Eutectic Solvents for Starch Treatment [PDF]

open access: yesPolymers, 2022
In this review, the application of deep eutectic solvents (DESs) as starch solvents, plasticizers and for other treatment has been described. Starch, as one of the most abundant biopolymers, is considered for forming new biodegradable materials. This new approach, referring to applying deep eutectic solvents for dissolving starch, its plasticization ...
