Summary: The study demonstrates a new strategy for capturing nitrogen dioxide (NO2) using deep eutectic solvents (DESs) and their aqueous mixtures. The results show that ChCl-based DESs have excellent NO2 absorption capability, which increases with increasing HBD content. Additionally, the DES aqueous mixtures retain high NO2 solubility while exhibiting a lower viscosity after the introduction of water.

Summary: This study evaluates deep eutectic solvents (DESs) as absorbents for volatile organic compounds (VOCs). Through static and dynamic processes, it is found that DESs have high absorption capacities for a variety of VOCs, without saturation even at high concentrations. One particular DES showed a maximum enhancement of absorption reaching 60000-fold for different VOCs at different temperatures. Additionally, the absorbent's capacity remained unchanged after multiple absorption/desorption cycles or water removal.

Summary: The efficient treatment of dichloromethane (DCM) is important for environmental protection and human health. This study proposes and investigates the strategy of capturing DCM using deep eutectic solvents (DESs) with different hydrogen bond acceptors (HBAs) and hydrogen bond donors (HBDs). The results show that tetrabutylphosphonium chloride: levulinic acid ([P-4444][Cl]-LEV) has the highest DCM absorption capacity among all DESs studied, and the interaction energy between DES and DCM plays a crucial role in the saturated absorption capacity of DCM.

Summary: Hydrofluorocarbons (HFC) are widely used compounds with a greenhouse potential 22,000 times higher than CO2. In this study, researchers examined 1298 type-5 deep eutectic solvents (DES) for their absorption and interaction mechanisms with difluoromethane (R32), and found that quaternary ammonium salts mixed with various hydrogen bond donators (HBD) showed the most favorable interactions. Compositional analysis showed that pure tetrabutylammonium bromide had the strongest interaction potential. Pressure study demonstrated that solubility increased linearly with pressure, reaching up to 86 mol/mol% in a mixture of methyltrioctylammonium bromide and polyethylene glycol at 9 bar. The driving force of absorption was van der Waals interaction, which released approximately 3 times more enthalpy than hydrogen bonding. Through environmental health and safety analysis, all chemicals showed strong potential for environmentally friendly solutions.

Summary: Atomic absorption spectrometry (AAS) is a widely used technique for metal quantification due to its practicality, easy use, and low cost. Sample pretreatment is commonly employed to improve the metrological characteristics of AAS, particularly the sensitivity and the detection limit. Deep eutectic solvents (DES) are being introduced into the analytical practice as new solvents in consideration of the principles of Green Analytical Chemistry. This article focuses on the potential of DES for the separation of metals and metalloids followed by AAS quantification, with an emphasis on their use in various liquid-liquid microextraction procedures.

Summary: Carbon dioxide (CO2) absorption in a non-aqueous solution was investigated using a deep eutectic solvent (DES) of choline hydroxide and polyamines, combined with non-aqueous solvents such as sulfolane and dimethylsulfoxide (DMSO). The study found that the 2M ChOH:TETA-DMSO solution had the highest CO2 loading capacity among the tested solutions. The absorption capacity increased with pressure and decreased with temperature, indicating the potential of using a DES polyamine mixed with a non-aqueous solvent for CO2 capture.

Summary: Volatile organic compounds (VOCs) are highly problematic atmospheric pollutants emitted from anthropogenic sources. In this literature review, the use of absorption based on deep eutectic solvents (DES) for capturing individual VOCs is critically summarized. The physicochemical properties of used DES, their impact on absorption efficiency, methods for evaluating the effectiveness of new technologies, and the potential for DES regeneration are discussed. The review also provides critical comments on new gas purification methods and presents future perspectives.

Summary: This article discusses a new deep eutectic solvent based on halogen bonding, which is different from the majority of DESs that rely on ionic components. The newly developed deep eutectic solvent remains in liquid form, with a eutectic melting temperature at different 1,3-dithiane mole fractions.

Summary: Deep eutectic solvent (DES)-like mixtures based on glycerol and different halide organic and inorganic salts have been successfully used as new media for copper-free halodediazoniation of arenediazonium salts. The reactions are conducted without the need for metal-based catalysts, at room temperature, and in a short period of time. Pure target products are obtained without the requirement of chromatographic separation. The solvents have been fully characterized and a computational study has been presented in order to understand the reaction mechanism.

Summary: The use of cyclodextrins (CDs) in combination with deep eutectic solvents (DESs) is a promising strategy for solvating hydrophobic compounds. However, the complexation mechanism of CDs in these non-conventional solvents is not well understood. This study investigates the complexation behavior and binding ability of CDs towards verbenone and camphor in a DES:water mixture. The results show the formation of stable inclusion complexes in the DES:water mixture, with similar thermodynamic signatures and stoichiometries of interactions as in water.

Summary: Nowadays, researchers are striving to find a solution to the problem of global warming, with a focus on reducing carbon dioxide emissions. The use of alkanolamines for carbon dioxide capture is problematic due to its corrosive nature, volatility, and high energy demand. Deep eutectic solvents (DESs) have emerged as a potential alternative, capable of physically and chemically absorbing carbon dioxide. Different strategies, such as the addition of water or co-solvents, have been proposed to enhance CO2 absorption using DESs. This review presents an overview of DESs, their impact on CO2 absorption, and practical considerations for their use in CO2 separation.

Summary: Deep eutectic solvents (DES) prepared with a chiral component can lead to new chiral solvents with applications in asymmetric synthesis and chiral light emitting materials. The study found that the chirality of the chiral hydrogen bond donor plays a crucial role in chiral discrimination by the chiral solvent, while the achiral hydrogen bond acceptor also plays a critical role in determining the handedness of the chiral discrimination.
