Summary: When selecting a solvent for a given solute, the commonly used idiom "like dissolves like" suggests using polar solvents for polar solutes. However, in deep eutectic solvents (DES), the components can be of various types, allowing for the solubilization of a wide range of solutes and the control of phase behavior through mixture design.

Summary: Deep eutectic solvents (DESs) are a rapidly expanding class of liquid phase mixtures that have many useful features. However, there is currently no widely accepted criterion for identifying whether a particular mixture is a DES or not. This study introduces a quantitative metric based on the molar excess Gibbs energy of a eutectic mixture and proposes a threshold value to classify a eutectic system as a DES.

Summary: The study found that solutes capable of forming hydrogen bonds are more easily extracted into DESs from cyclohexane. For less polar solutes, the choice of DES has a more significant impact on extraction efficiency. However, for polar solutes, the influence of DES is less pronounced.

Summary: This study investigated the impact of a covalent link between hydrogen bond donor species on the behavior of deep eutectic solvents (DES). The presence of a glycosidic bond in trehalose limited the movement of sugar units, resulting in fewer interactions with choline chloride in DES(t). This limitation influenced the physical state of DES(t), making it behave more like a semi-solid material compared to the liquid-like behavior of DES(g).

Summary: Thermoresponsive poly(N-isopropylacrylamide) (polyNIPAM) hydrogels were prepared via free radical polymerization in deep eutectic monomer solvents (DEMs) for the first time, where NIPAM served as a polymerizable hydrogen bond donor. The hydrogels prepared with DEMs showed increased cross-linking density and mechanical strength compared to those prepared in aqueous polymerization, exhibiting unique thermoresponsive swelling behavior.

Summary: The efficiency of potato starch plasticization using two deep eutectic solvents (DESs) based on choline chloride (CC) and glycerol (G) or urea (U) has been evaluated. Both DESs exhibited solubility towards starch, but CCU showed significantly higher solvent power than CCG. The XRD result indicated that both DESs were able to penetrate the starch crystal regions and form stable hydrogen bonds with the hydroxylic groups of the polysaccharide. The viscosity and thermal stability of the starch material depended on the DES content, with a decrease in viscosity and thermal stability observed with increasing DES content. The gelatinization temperature was strongly affected by the type of DES, occurring at a lower temperature in CCU compared to CCG. The plasticization efficiency was tested using modulated DSC, and it was found that CCG had higher plasticizing efficiency compared to CCU.

Summary: Using deep eutectic solvents as suitable media can improve the transmittance detection modes on microfluidic paper-based analytical devices, providing higher transparency and long-term analysis capability. Detection of dye in ethaline solutions showed good repeatability and wide concentration range, while detection in water solutions was unsatisfactory due to solvent evaporation and interference from recorded spectra.

Summary: A rhodium-catalyzed oxidative C-H/N-H dehydrogenative[3 + 2] annulation strategy has been developed for the synthesis of 2-methylindole scaffolds by reacting anilines and N-allylbenzimidazole. This transformation involves the cleavage of the thermodynamically stable C-N bond of allylamine and proceeds through a cascade of C(sp(2))-H alkylation followed by intramolecular cyclization. Detailed mechanistic studies have been performed to identify a key intermediate.

Summary: This paper introduces the evaluation method of thermal stability of deep eutectic solvents (DESs). Traditional thermogravimetric analysis (TGA) has issues such as decomposition overlap and low resolution, while high-resolution TGA (HR-TGA) can more accurately evaluate the thermal stability of DESs.

Summary: Four novel push-pull D-pi-A type chromophores were synthesized and characterized in this study. The synthesized dyes exhibited absorption and emission wavelengths, with varying Stoke shifts. By investigating parameters such as oscillator strengths and solvent polarity plots, the intramolecular charge transfer characteristics of these chromophores were understood. Additionally, viscosity-induced emission was observed in ethanol: polyethylene - 400 solvent mixtures for all four chromophores. Computational studies were also conducted using density functional theory (DFT) and time-dependent density functional theory (TD-DFT).

Summary: We have prepared a commercially viable Deep Eutectic Solvent (DES) based on Choline Chloride-Urea-copper acetate for the first time. It mediates the homocoupling of terminal alkynes, using air as an oxidant. Water is the only by-product of the entire process. The method avoids ligands, bases, oxidants, and costly palladium catalysts, making the process greener than ever. The DES can be reused at least three times without significantly affecting the reaction yield. The key features of the protocol, including ambient reaction temperatures, lesser use of conventional organic solvents, higher yields, and easy product isolation, qualify the process as a green one.

Summary: A mixed metal oxide-based spinel ceramic pigment incorporating inorganic, high-temperature stable furnace cement as a binder was successfully synthesized. The pigment mix was applied as a coating to different substrates, showing better spectral selectivity and application ease compared to solvent-based coatings. The presence of cement as an inorganic binder greatly influenced the size, morphology, and crystallinity of the spinel mix, making it suitable for high-temperature applications.
