Summary: Dilution of ionic liquid with appropriate cosolvents can modify the physicochemical properties, and even low concentrations of cosolvents can lead to significant changes in their dynamics. Molecular dynamics simulations were used to study the impact of cosolvent polarity on the motional features of ionic liquids. The presence of cosolvents affects the diffusivity of ions and cosolvents, with dipolar acetonitrile causing the fastest ion diffusion in the mixture.

Summary: Molecular dynamics simulations were used to study the dissociation of CO2 hydrates in the presence and absence of the ionic liquid [BMIM][PF6]. It was found that the presence of [BMIM][PF6] had a minimal effect on hydrate thickness, but reduced the deviation from hydrate-like behavior. This was attributed to the preferential association of CO2 with the [PF6]- anion and the asymmetry in the density profiles of CO2 and H2O.

Summary: Researchers have used halloysite nanotubes as nanocontainers to load ionic liquid. The lumen of the nanotubes is functionalized to improve the uptake of the ionic liquid, and a polydopamine layer is used as an end-stopper to prevent premature release. The resulting microcapsules are incorporated into a textile composite liner, leading to a decrease in wear rate compared to pure composites due to the formation of a robust tribofilm on the surface.

Summary: In this study, molecular dynamics (MD) simulations were used to investigate the electrical behavior of atomic charges of a fullerene in an ionic liquid. By combining solute-solvent configurations and density functional theory (DFT) calculations, the convergence of atomic charges and dipole moment during the dissolution process was obtained through an iterative process of MD simulations and DFT calculations. A comprehensive analysis of atomic charge behavior was conducted to examine the impact on solute-solvent structure, highlighting the importance of complete solute polarization in the solution. Additionally, quantum calculations of nuclear magnetic resonance (NMR) and absorption spectra were performed to observe the impact of electronic C-60-solvent interaction on spectroscopy results, revealing a smaller chemical shift and a more intense electronic transition band for the fully polarized C-60 in solution.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: This article presents the mutual diffusion coefficients of a carbon dioxide-ionic liquid system at different temperatures and pressures. The diffusion coefficients were estimated by conducting experiments and fitting a transport model to the data. The study found that during the process of carbon dioxide dissolution in the ionic liquid, the position of the liquid-vapor interface and the density of the liquid phase changed. The results were compared with literature values and correlations.

Summary: The study systematically investigated the influence of charge density and ionic strength on the performance of nanofiltration membranes, revealing that low charge density limits polyelectrolyte adsorption and retention, while high charge density affects membrane surface charge and pure water permeability. Increasing ionic strength is crucial for high charge density polyelectrolytes, but has an opposite effect on membrane properties depending on the type of polyelectrolyte used.

Summary: Direct collection of uranium from low uranium systems via adsorption remains challenging. Fibrous sorbent materials with amidoxime (AO) groups are promising adsorbents for uranium extraction from seawater. The utilization of AO adsorption groups is improved by fabricating a branched structure containing AO groups on polypropylene/polyethylene spun-laced nonwoven (PP/PE SNW) fibers using grafting polymerization induced by radiation (RIGP). The adsorbent material shows a high adsorption capacity and good stability, demonstrating its potential for seawater uranium extraction.
