Summary: The study found that the influence of imidazolium-based ionic liquids on the transport of TiO2 nanoparticles depended on the species, alkyl chain length, and counteranions. The inhibitory effects were mainly controlled by the hydrophobicity of the ILs and electrostatic repulsion between nanoparticles and porous media. Additionally, the inhibitory role of ILs was more pronounced under acidic conditions compared to alkaline conditions.

Summary: This Perspective highlights the pathways to prepare porous ionic liquids using easily accessible materials for reduced environmental impact. The study demonstrates that suspensions of porous solids are stable in eutectic mixtures, which indicates their potential in preparing porous ionic liquids. Porous ionic liquids maintain the wide electrochemical window observed in their precursor pure ionic liquids, making them suitable for green electrochemical reactions, especially those involving gases with enhanced solubility in the porous suspensions. Furthermore, their capacity as gas-rich media suggests potential sustainable biomedical and pharmaceutical applications, provided that non-toxic, biocompatible ionic liquids and porous solids are utilized.

Summary: In this study, it was found that cellulose slightly swelled in the chloride-based deep eutectic solvent compared to the acetate-based solvent, possibly due to stronger hydrogen bonding between the chloride anion and hydrogen atoms of cellulose. Moreover, the chloride anion approached the outer glucose units more closely, indicating the beginning of cellulose dissolution.

Summary: The large amount of sewage sludge produced has caused a significant environmental burden. Sludge dewatering is an effective method to reduce sludge volume, and five imidazole-based ionic liquids were used to improve its dewaterability. Among them, 1-ethyl-3-methylimidazolium dihydrogen phosphate ([Emim] [H2PO4]) showed excellent performance and reusability, with a 10% higher solid content compared to cationic polyacrylamides (CPAM). The mechanism of how ionic liquids enhance sludge dewatering was studied, and it was found that acidic ionic liquids like [Emim] [H2PO4] could alter the zeta potential and microstructure of sludge particles, leading to improved water release.

Summary: Molecular dynamics simulations were performed to investigate the absorption of gases (NH3, N-2, H-2) by different types of ionic liquids (protic IL [Bim][Tf2N] and conventional IL [Bmim][Tf2N]). The results revealed that the interaction between NH3 and the [Bim](+) cation was stronger than that between NH3 and [Bmim](+) cation, resulting in high selective absorption of NH3. The increased number density of cations near the IL-gas interface facilitated the rapid and effective permeation of NH3 molecules.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
