Summary: In this study, deep eutectic solvents (DESs) with different urea (U) contents were prepared and used as plasticizers for potato-starch. The influence of different DES compositions on the physicochemical properties of thermoplastic starch (TPS) was investigated. The results showed that increasing the U content led to higher phase-transition temperatures and lower thermal stability. Additionally, higher U content resulted in higher elongation at break and a highly amorphous structure in the TPS.

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: The research found partial compatibility of cassava starch and corn starch with polycaprolactone (PCL) in the blends, along with changes in crystal quality of PCL and displacement of absorption bands in the infrared spectrum. The crystallinity of PCL in the presence of cassava and corn starch was higher than that of pure PCL, suggesting improved nucleation at the interface. Based on these findings, the blends are suitable for manufacturing short-term use products using conventional thermoplastic processing methods.

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: A method using new extraction solvents is proposed for completely decolorizing textile wastewaters, aiming to drastically reduce water consumption. This technique allows for water reuse and addresses one of the textile industry's biggest challenges of generating enormous amounts of liquid residues. Dyes are the most common pollutants in these effluents, posing toxicity risks to humans, aquatic life, and the environment. Achieving full decolorization is essential for obtaining clean water that can be repurposed according to circular economy principles.

Summary: Deep eutectic solvents (DES) are a type of ionic liquid formed by a mixture of hydrogen bond donors and quaternary ammonium salts, leading to decreased melting points and increased solubility. By formulating pharmaceutical deep eutectic solvents (PDESs) from APIs, the rate of drug uptake can be increased via both oral and transdermal delivery modes. This study shows that PDESs can release drug components more efficiently compared to pure drugs, especially for catechol which showed more than double the dissolution rate after 1s.

The results show that the solvent anion has a greater impact than the salt anion. Despite different starting salts, the copper species remain the same, except for copper(i) salt and copper(ii) acetate system that show concentration dependence.

Summary: This roadmap presents the market dynamics and their influence on a future circular economy for lithium-ion batteries (LIB), with a focus on safety throughout the life cycle. Various options for end-of-life (EOL) disposal, such as remanufacturing, reuse, and recycling, are discussed. Diagnostics play a crucial role in assessing battery health and condition, and improvements to diagnostic techniques are evaluated. The future of LIB recycling lies in automated dismantling of EOL battery packs and the development of design for recycling and new cell design approaches.

Summary: Extraction of active compounds from natural materials faces challenges of large solvent volumes, greenhouse gas emission, and energy requirements. This study presents a novel approach of forming deep eutectic mixtures through mechanical action on a solid-state mixture containing a quaternary ammonium salt and a biological material. The eutectic mixtures formed can selectively extract active compounds from natural products, which are then purified using liquid/liquid extraction. The resulting natural extracts exhibit high antioxidant activities.

Summary: Waste collagen was processed with a deep eutectic solvent (DES) of ChCl:2EG to produce a material similar to leather. The resulting material from waste tanned collagen treated with ChCl:2EG and mechanically extruded showed similar characteristics to animal hide powder material, but with significantly higher tensile strength (7.56 MPa vs. 0.23 MPa). The improved strength and structure may be attributed to the addition of traces of iron during extrusion of the acidic collagen sample. However, the generated material exhibited lower crystallinity compared to commercial leather samples. Overall, this process provides a simple method for utilizing waste collagen to create useful materials through the intervention of DESs.
