“…The viscosity and density data of pure Reline DES were retrieved from the literature. 53 The reported data cover the defined range of water percentages from 0.05% to 5% at 25 °C. From the presented table, it is clear that increasing the water quantity leads to an increase in conductivity.…”

“…Similar observations were reported for ChCl:urea at high pressure and temperature ranges between 298.15 to 323.15 K. Yadav and Pandey [74] have also studied the aqueous solution of this DES from 298.15 to 363.15 K. The quadratic expression was presented to show decreasing behavior of density with increases in temperature. Lapeña et al [75] have also reported densities of a DES composed of ChCl:urea at 1:2 molar ratio and aqueous mixtures (x DES = 0.645) at temperature ranges between 288.15 K and 338.15 K for the DES and at a temperature range between 278.15 K to 338.15 K for the aqueous DES. The density of a hydrated DES was found to be less in comparison to pure DES due to a decrease in hydrogen bonding between HBA:HBD with the addition of water [75].…”

Recently, deep eutectic solvent (DES) or ionic liquid (IL) analogues have been considered as the newest green solvent, demonstrating the potential to replace harsh volatile organic solvents. DESs are mainly a combination of two compounds: hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD), which have the ability to interact through extensive hydrogen bonds. A thorough understanding of their physicochemical properties is essential, given their successful applications on an industrial scale. The appropriate blend of HBA to HBD can easily fine-tune DES properties for desired applications. In this context, we have reviewed the basic information related to DESs, the two most studied physicochemical properties (density and viscosity), and their performance as a solvent in (i) drug delivery and (ii) extraction of biomolecules. A broader approach of various factors affecting their performance has been considered, giving a detailed picture of the current status of DESs in research and development.

“…In the majority of instances, the viscosity of DES is higher than 100 cP at ambient temperature [104][105][106][107][108][109][110][111]. This issue arises from the existence of an immense structural network of hydrogen bonds.…”

“…According to the literature review, there are a few theoretical studies in the field of DES-based nanofluids. However, many reports have focused on the analysis of the DES behavior and its characteristics, which are constantly updated [99,[104][105][106][107][108][109][110][111][129][130][131][132][133][134][135][136][137].…”

Nowadays, different types of strategies are proposed and tested to find the best scenario for upgrading the productivity of heat transfer fluids, especially nanofluids. Some optimum empirical conditions demonstrated that the best size, shape, and nature of nanoparticles and their appropriate dispersion have positive influences on nanofluid thermal conductivity improvements. Therefore, the specific physicochemical properties of the base fluid can be taken into account as one of the decisive factors in heat transfer operations. Deep eutectic solvents (DESs) are nominated as valuable materials to meet the demands for sustainable ecological processes and open opportunities for overcoming the limitations of conventional fluids.The purpose of this study is to briefly introduce the DESs for evaluating their thermal potential applicability and their use to produce nanofluids. DES-based nanofluids represent a new and creative type of heat transfer fluids that possess high potential in different target applications and are not harmful to the environment. This type of nanofluid has higher thermal properties than the base DESs. Increasing the temperature and the volume fraction of nanoparticles lead to further increment in their thermal properties. In this study, the chemical structure and preparation method have been addressed for the DES and DES-based nanofluids. Also, the theoretical approaches have been considered for modeling and predicting their behavior. A discussion was extended to investigate the usage of DES as host fluid for producing nanofluids, and its advantages and drawbacks are also presented. It is deduced that the DES-based nanofluids are one of the smart choices for the progression of nanofluids and give the most promising results for application in heat transport fluids. The contents may shed light on a detailed awareness of the heat transfer potential of the DESs.
