Summary: Graphene oxide (GO) is a promising candidate for solar absorbers to address freshwater crisis, but its easy delamination in water poses a challenge for practical solar desalination. By using a self-crosslinking poly (ionic liquid) (PIL), the stability of GO membranes is improved without affecting the hydrophilic structure of GO. The addition of carbon nanotubes (CNTs) further enhances the stability of the GO/CNT@PIL (GCP) membrane and reduces water evaporation enthalpy, resulting in a high evaporation rate and long-time durability under irradiation. The GCP membrane also works well with different water sources and shows potential for practical solar seawater desalination.

Summary: Articular cartilage defects cause disability and global socioeconomic loss. However, the limited regeneration ability of cartilage tissue due to its avascular and nearly acellular nature poses challenges for repair and regeneration. Smart biomaterials can regulate cell behavior, provide a favorable microenvironment and induce articular cartilage repair and regeneration. The use of smart drug release systems and smart scaffolds in these processes is discussed, as well as the importance of advanced manufacturing techniques and clinical translation of smart biomaterials.

Summary: This Perspective discusses the structures of ionic liquids (ILs) and the aggregations that can significantly alter their micro-environment and impact their properties and functions. The mesoscale structures of IL aggregation in pure ILs and ILs-solvent mixtures are analyzed based on interacting forces and thermodynamics. The potential applications of IL aggregation in various scientific and engineering fields are explored, such as biomass conversion, smart materials, and life medicine. The challenges and opportunities in the field of IL aggregation, including direct observation techniques, large-scale simulations, theoretical forming mechanisms, and coupling mechanisms with solid interfaces, are also discussed. These new perspectives shed light on the rational design of ILs and generate research interest in ILs as a green medium in chemical engineering.

Summary: Molecular dynamic simulations were conducted to investigate the relationship between the microscopic structures changed by water and the ionic diffusivity in aqueous mixtures of imidazolium ionic liquids (ILs). Two distinct regimes of ionic diffusivity were identified with increasing water concentrations, which are directly correlated to the ionic association. The study also revealed two general relationships between ionic diffusivity and ion-pair lifetimes, as well as short-ranged interactions between cations and anions.

Summary: In this study, the regulating mechanism of structural, thermodynamical, and diffusive properties of 18 imidazole ionic liquids (ILs) with different anions was investigated using molecular dynamics simulations and theoretical analysis. It was found that the radial distribution function and coordinate number of these ILs were similar, while the vibrational spectrum and diffusive property varied greatly with the anion structure, resulting in a significant change in the self-diffusive coefficient (SDC). Moreover, the SDC was found to have an exponential relationship with free energy and entropy, suggesting that these can be key indicators in designing high-performance ILs for practical chemical engineering applications.

Summary: Understanding the interfacial structure and flow behavior of ionic liquids (ILs) confined in nano-channels is crucial for the design and application of IL-based chemical engineering devices. Molecular dynamics simulations reveal that the cations in crystalline silica (c-SiO2) exhibit a vertical conformation, while those in graphene-covered crystalline silica (g@c-SiO2) display a parallel conformation. The anions, on the other hand, are randomly distributed. The different cation conformations result in distinct ion diffusion and flow patterns, with the parallel conformation facilitating nanoflow in the g@c-SiO2 channels. These findings provide valuable insights into the molecular mechanism of nanoflow and inform the rational design of IL-based devices and chemical engineering processes.
