Summary: In this study, the phase behavior of choline chloride (ChCl) + ethylene glycol (EG) mixtures was investigated. It was found that ethaline, the commonly believed eutectic point composition, is actually in the ChCl-saturated region of the phase diagram. The real eutectic point was determined to be at a molar ratio of 1:4.85 of ChCl : EG. Despite ChCl being an electrolyte, the phase diagram exhibited ideal binary mixture behavior.

Summary: The study discusses the molecular origin of the large melting point depressions observed for deep eutectic solvents (DESs) and points out the lack of understanding about the relationship between DES liquid microstructure and macroscopic properties. The researchers call for experimental quantification of the observed balance between interactions and disorder at the molecular level and the incorporation of this data in thermodynamic models for calculation and prediction of solvation properties and eutectic depth.

Summary: The supercooled liquid state of a deep eutectic solvent (DES) composed of a mixture of choline chloride and citric acid monohydrate (CA) was studied. The viscosity of the supercooled DESs, which increased with higher CA content, could be described by an Arrhenius equation. Surface tensions were considerably high, comparable to that of water, and slightly decreased with higher CA concentration. The wetting behavior of supercooled DESs on glass was characterized by an unusually slow spreading process, and the equilibrium contact angle increased with higher CA content.

Summary: The peri-eutectic transition L+6-Fe ->gamma-Fe(Ni)+Fe2Ti in ternary Fe66.5Ni17.6Ti15.9 alloy was investigated using directional solidification technique. The primary phase and peri-eutectic had a common orientation relationship, while the eutectic had multiple orientation relationships. This study provided evidence for different growth mechanisms and clarified the nucleation and growth of the peri-eutectic phase.

Summary: Research has shown that liquid gallium oriented towards the direction of the substrate rubbing exhibits anisotropic reflection at 120 degrees Celsius, which increases on cooling and persists down to room temperature or below. Additionally, mechanical shear force induces anisotropic reflection, which relaxes after a few seconds.

Summary: The effect of temperature on dynamic viscosity and atomistic structure in liquid eutectic Ga-Sn alloy was investigated using a torsional oscillating viscometer, an X-ray diffractometer, and molecular dynamics simulation. The results showed that liquid-liquid structure transitions occurred around the liquidus temperature and within the range of 1073 to 1273 K. Below and above these temperatures, the liquid exhibited differences in viscosity, coordination numbers, and correlation radius of clusters, which were indicative of structural changes in terms of structural disorder and local atomic packing. This study will stimulate further research on liquid-to-liquid crossover in the liquid-solid transition.

Summary: This paper presents a suite of techniques to measure the electrical and interfacial properties of room-temperature liquid eutectic gallium indium (EGaIn) as a function of applied electric potential. The study provides new insights into the mechanisms that cause the significant decrease in interfacial tension. A key finding is the hysteresis behavior of the interfacial tension with lowering applied potential. The authors combine these observations with electrochemical impedance spectroscopy to evaluate the changes in interfacial tension arising from chemical, electrical, and mechanical changes on the interface.

Summary: This study used three organics and a hydrogen bond acceptor to form deep eutectic solvents (DESs) for freeze-casting super-macroporous materials. The DESs showed smaller pore sizes and higher specific surface area compared to conventional porogens, resulting in hydrophobic cryogels with improved properties. The study also presented a strategy combining computational screening and experimental validation to design DESs with suitable properties, allowing for an adjustable pore structure in hydrophobic cryogels.

Summary: This article presents a novel class of deep eutectic electrolytes (DEEs) with distinctive properties for sodium batteries. The concept of Na center dot center dot center dot N interactions, involving sodium bis(fluorosulfonyl)imide (NaFSI) and 1,2-dimethylimidazole (DMIm), is introduced for the first time. The deep eutectic phenomenon is caused by strong ion-dipole interactions, leading to desirable ionic conductivity and excellent performance in sodium battery applications.
