Summary: Anthocyanins are extracted using alternative solvents such as ionic liquids, deep eutectic solvents, and natural deep eutectic solvents, which are more environmentally friendly and efficient compared to conventional solvents. Acid-based deep eutectic solvents with 20-30% water content showed the highest anthocyanin extraction yield. Ultrasonic-assisted extraction was the most common and efficient method, and DES-based extracts exhibited the highest stability and antioxidant activity. Fruits and their by-products are the most commonly used samples, while cereal and legumes are less explored.

Summary: The study demonstrates that hydrophobic deep eutectic solvents (DESs) are efficient in eliminating hydrophilic VOCs due to their high absorption capacity and favorable gas-to-liquid mass transfer. Among the DESs explored, the one containing thymol and decanoic acid in a 1:1 molar ratio exhibits the highest acetone absorption capacity, showing the key role of hydrogen bonding interaction in achieving superior solubility of acetone in DESs. The absorbed acetone can be easily removed from the DESs, making the process economically and ecologically beneficial for hydrophilic VOC elimination.

Summary: In recent years, there has been a significant increase in the search for green chemistry principles in analytical methods. Solvents play a crucial role in green analytical chemistry, and certain criteria must be met for a solvent to be considered green, including availability, low toxicity, biodegradability, and low cost. However, the availability of green solvents is currently limited. Deep eutectic solvents (DESs) have emerged as a new and promising alternative to traditional solvents, attracting attention for their eco-friendly, inexpensive, and easily obtainable characteristics. This work provides a critical review of the use of DESs in liquid-phase microextraction (LPME) and their contributions to green chemistry.

Summary: Many studies have focused on the physicochemical properties of ionic liquids (ILs), but less attention has been given to interfacial properties involving deep eutectic solvents (DES). The knowledge of DES-electrode interactions is lacking, which hinders the proposal of a suitable Electrical Double Layer model (EDL) for the description of DES at electrified interfaces. Measuring differential capacitance-potential curves is crucial for understanding the EDL structure and designing electrochemical systems. In this study, choline chloride-based DESs with different hydrogen bond donors (HBDs) were evaluated against different electrodes, and the differential capacitance-potential curves varied significantly depending on the electrode surface.

Summary: A new concept of green solvents called superlong supercooling solvents (SSSs) is proposed, which are metastable liquid solvents that can be used at temperatures around or slightly higher than room temperature before condensing after a superlong time. SSSs can serve as green alternatives to water, supercritical fluids, ionic liquids, and deep eutectic solvents (DESs).

Summary: The increasing energy consumption has led to a rise in sulfur emissions, causing economic and health issues, as well as impacting the efficiency of diesel engine emission control systems. To combat this, research is being conducted on various desulfurization technologies, including conventional methods like hydrodesulfurization and alternative processes such as adsorptive, extractive, oxidative, and bio-desulfurization. Factors such as DES selection, extraction temperature, extraction time, DES regeneration, and multistage extractions play a crucial role in the desulfurization efficiency, with deep eutectic solvents showing promise as a less toxic and more efficient alternative for extractive desulfurization.
