Water-induced changes in choline chloride-carboxylic acid deep eutectic solvents properties

Extraction of phenolic compounds from lucuma (Pouteria lucuma) seeds with natural deep eutectic solvents: modelling using response surface methodology and artificial neural networks

“…The HBD and HBA components used in this study are watersoluble and hygroscopic. Due to the interactions between water molecules and NADES components, the hydrogen bond network may be altered, leading to changes in the system's viscosity, density, and electrical conductivity (Ninayan et al, 2023). In this research, it was necessary to incorporate 20% of water (w/w) to reduce the viscosity of the NADES, thus facilitating the diffusion of polyphenols, as has been observed in previous studies (Karakashov et al, 2015;Bakirtzi et al, 2016).…”

“…Generally, a concentration higher than 50% can break the hydrogen bond between HBD and HBA (Dai et al, 2015;Moradi et al, 2023) and decrease the interactions between NADES and polyphenols, affecting the performance of extraction (Peng et al, 2016). It is known that the presence of water can complicate specific reactions by competing for hydrogen bonding sites or affecting the local concentration of reactants (Ninayan et al, 2023). Additionally, DES formed by hydrophilic HBA or HBD components could leach into water due to their solubility (Florindo et al, 2017(Florindo et al, , 2019.…”

Commercial-Grade Dielectrics Surface Metallization by Direct Laser Deposition from Deep Eutectic Solvents

“…From a technological point of view, hydrophilic DES is more advantageous due to its cost-effectiveness, ability to be removed by water, and tunability of properties via water content. 53 In this context, surface structuring represents a promising approach for overcoming the mismatch in hydrophilicity between DES and the substrate.…”

“…The surface texture can significantly change the contact angle due to morphology and laser-induced formation of new surface functional groups. ,, As PTFE is hydrophobic, surface modification can enhance coverage by hydrophilic DES, leading to the formation of continuous copper patterns. From a technological point of view, hydrophilic DES is more advantageous due to its cost-effectiveness, ability to be removed by water, and tunability of properties via water content . In this context, surface structuring represents a promising approach for overcoming the mismatch in hydrophilicity between DES and the substrate.…”

Possibility of replacing conventional organic solvents with green Deep Eutectic Solvents in drug analysis

“…For this reason, researchers have addressed this problem by the preparation of low-viscosity DESs from ChCl and carboxylic acids (citric acid, lactic acid, tartaric acid, malic acid, and malonic acid). In addition to the preparation described, the DESs were classified, for the first time, according to the number of functional groups and rheological properties (44). The preparation of a eutectic mixture based on ChCl and glycerol was also described in detail as another example of DESs in which the high viscosity was overcome (45).…”
