Summary: This study investigated the possibility of using electrodialysis (ED) to recover 1,3-dialkylimidazolium ionic liquid (IL), specifically N,N-dibutylimidazolium chloride ([C4C4IM]Cl). The results showed that ED allows for the recovery and concentration of [C4C4IM]Cl from dilute aqueous solutions, with the [C4C4IM]Cl content in the concentrates being over three times higher than in the initial solutions. The highest recovery and ED efficiency were obtained when the initial [C4C4IM]Cl concentration in the solution was 20 g/L.

Summary: Using cost-effective and environmentally friendly molecular crowding agents to replace highly concentrated salts is a promising strategy to suppress water decomposition in electrochemical energy storage devices. However, the lack of comprehensive understanding on how a crowding agent structure affects the key properties of electrolyte prevents rational design of molecular crowding electrolyte for high-power and high-voltage aqueous batteries. On the basis of the design principles revealed, we developed a new crowding agent, polyethylene glycol dimethyl ether (PEGDME) 450, demonstrating 3 times higher conductivity (2.4 mS cm(-1) vs 0.8 mS cm(-1)) than state-of-the-art polyethylene glycol (PEG) 400 without sacrificing the voltage window (3.2 V). A high-power and high-voltage aqueous Li4Ti5O12/LiMn2O4 cells with this new electrolyte operated (5 C, 72 Wh kg(-1) vs 10 Wh kg(-1) PEG400) for 800 cycles. This work demonstrates a universal strategy for advanced aqueous electrolyte design and high-performance batteries.

Summary: This study focuses on the application of imidazolium-based polymeric ionic liquids (PILs) as absorbents in two-phase partitioning bioreactors for the removal of n-butanol from dilute aqueous solutions. The synthesis and phase transition temperatures of poly(1-vinyl-3-alkylimidazolium) bromides with different alkyl groups, architectures, and compositions, as well as analogs with various inorganic and carboxylate anions, are described. Equilibrium experiments are conducted to quantify the solute affinity of each PIL, which is measured by the n-butanol partition coefficient (PCBuOH) and n-butanol/water selectivity (alpha(b/w)). A complete ternary phase diagram is created to propose a streamlined n-butanol recovery process.

Summary: The self-assembly behavior of ionic liquids in aqueous solution was studied through molecular dynamics simulations, revealing the dominant role of interactions between tail groups in stabilizing vesicles and the influence of membrane thickness and alkyl chain arrangement on vesicle permeability. The interdigitated structure of tail groups reduced water exchange rate, while the orientation of the imidazolium ring promoted water molecules approaching hydrophobic regions. These findings suggest the potential for obtaining vesicles with excellent permeability properties by screening the hydrophilic and hydrophobic properties of ILs for applications in separation and drug delivery processes.

Summary: This study evaluated the metal sorption capacity of six macroalgae, two microalgae, and three cyanobacteria for Co2+, Cu2+, Ni2+, and Zn2+. Brown macroalgae, particularly Undaria pinnatifida, showed the highest metal sorption capacity. Overall, macroalgae performed better than microalgae, followed by cyanobacteria. Carboxyl groups were identified as the main functional groups involved in metal sorption, and all biomass samples were selective to Cu2+. The release of K+ and Ca2+ during the metal sorption process indicated an ion-exchange mechanism, except for red macroalgae.

Summary: Aqueous biphasic systems (ABSs) based on sodium polyacrylate (NaPA), ethylene oxide/propylene oxide (EO/PO) polymers, and (EO)x-(PO)y-(EO)x triblock copolymers were prepared and applied for continuous fructooligosaccharide (FOS) production and separation. The hydrophilicity/hydrophobicity balance of EO/PO had a significant effect on ABS formation. Different carbohydrates and levansucrase showed different partition behavior in these ABSs. By selecting the appropriate ABS composition, high yields of FOS and selective partitioning could be achieved. COSMO-RS suggested that ABS formation was due to competition between NaPA and polymers/copolymers to form hydrogen bonds with water molecules.

Summary: In this study, the SAFT-gamma-Mie equation of state was used to develop coarse-grained molecular models for describing micellization phenomena in a top-down approach. Polyethylene oxide (PEO)/polypropylene oxide (PPO) triblock copolymers in aqueous solutions were selected as the case study. The model was successfully fitted to reproduce the thermophysical properties and liquid-liquid phase diagrams of PEO/PPO oligomers and their mixtures with water. Molecular dynamics simulations showed the formation of spherical micelles with star-shaped or flower-shaped morphology at low concentrations, and the formation of larger micelles or aggregates at higher concentrations.

Summary: The widespread presence of metals in water bodies has driven the development of platforms for their removal and recovery. Biosorption, specifically using algae, has emerged as a sustainable and cost-effective method for metal removal from wastewater. However, there are still gaps in the research, such as limited studies in natural wastewater and a lack of consideration for ion and metal competition. This study explores the application of non-living algae for metal recovery and compares their sorption capacity with other wastewater matrices, as well as evaluating the cost performance compared to commercial and waste-based sorbents.

Summary: This study investigates the behavior of deep eutectic solvents (DES) using inelastic neutron scattering (INS) spectroscopy. By calculating the vibrational modes of pure compounds and analyzing the spectra of binary mixtures, deviations from ideality in the mixtures of tetraalkylammonium salts with urea are observed. Unlike other systems, the deviation from ideality in the deep eutectic system comprised of [N2,2,2,1]Cl and urea is attributed to entropic rather than enthalpic factors.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
