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: The physico-chemical changes occurring during the high-temperature phase transformation of monazite in the presence of Na2CO3 at 1000 C for 2 h duration at monazite: Na2CO3 ratios between 1.0 and 5.0 were investigated. The formation of sodium lanthanide phosphates was prevalent above a monazite:alkali ratio of 2, however, below this ratio, the dephosphorization of monazite as Na3PO4 and Ce(1-x)Ln(x)O(2-x/2) solid solutions occur offering unique selectivity for rare-earth oxide separation from the mineral matrix. Cyclic voltammetry of pure CeO2, La2O3, Nd(2)O3, and PrO2/Pr2O3 was carried out in the deep eutectic solvent Ethaline (1:2 mixture of choline chloride and ethylene glycol) proving the electrochemical activity of these oxides. Electrodissolution of pure oxides and water-leached monazite after high-temperature reaction with a ratio of 1:1 was carried out in a 0.1 mol/L glucose solution in Ethaline showing a preferential solubility of 23.85% for pure Nd2O3. In contrast, pure oxides of CeO2, La2O3 and PrO2/Pr2O3 were found to be insoluble. We also observed that electrodissolution of the water leached monazite was not possible because of the inert behaviour of Ce(1-x)Ln(x)O(2-x/2) solid solutions. Avoiding cerium oxidation during the high-temperature process will lead to a method for further selectivity for rare-earth oxide processing using staged electro-chemical winning of oxides.

Summary: With the increasing demand for renewable energy, solar energy is expected to play a significant role. However, the disposal of end-of-life solar cells can result in a substantial amount of valuable metal components going to waste. This study explores a novel approach using redox catalysts to dissolve silver and aluminium from silicon solar cells, achieving high recovery rates and purity. The use of brines as solvents presents a cheaper and environmentally friendly alternative to mineral acids.

Summary: A novel catalytic approach using cellulose sulfuric acid (CSA) as a green catalyst was developed for the synthesis of symmetric and asymmetric azines. The method showed high percentage yield, mild reaction conditions, broad substrate range, and environmentally benign characteristics, making it suitable for large-scale industrial manufacturing. Molecular docking analysis revealed the possible binding interactions between the azine derivatives and the target protein MAO-A, with some derivatives showing major conserved interactions, while others exhibited low binding activity.

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.

It demonstrates a continuous relationship between molar conductivity and fluidity, regardless of cation, charge density, or ionic radius. The diffusion coefficients of specific metal chlorides in various ionic fluids show a linear correlation with fluidity. By adjusting chloride and water activity, selective etching of mixed metal waste streams can be achieved.

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.

Summary: This study investigated the speciation and reactivity of iodine in high chloride solvents, and found that iodine species can be classified into three groups: I2Cl-/I-3(-), I-3(-)/I-2, and I-3(-). UV-vis spectroscopy confirmed the speciation, and electrochemistry experiments showed that the redox behavior of iodine was not affected by the changing speciation. Leaching experiments revealed that the metal oxidation was influenced by both iodine speciation and the reactivity and coordination ability of the solvent.
