Summary: The thermodynamic and electrochemical properties of Ag+ ions in ChCl and G mixture were investigated, and MD and DFT methods were used for computational simulation. The specific mass, speed of sound, viscosity, and refractive index of the solution were measured at different temperatures. The electrochemical behavior of Ag+ ions was analyzed by cyclic voltammetry, and silver coatings were successfully electrodeposited on the Au surface. SEM analysis revealed the surface morphologies of the electrodeposits. The computational calculation showed that adding silver nitrate to the eutectic solvent had a predominant repulsive effect and negligible influence on sound velocity and refractive index. MD simulations demonstrated a strong interaction between Ag+ ions and Cl ions.

Summary: Mesoporous titanium dioxide particles (TiO2) were synthesized through reactive precipitation using the supercritical anti-solvent (SAS) technique with carbon dioxide and the ionic liquid (IL) 1-methyl-3-octylimidazolium bis[trifluoromethylsulfonyl] imide, [C(8)mim][NTf2]. The particles exhibited anatase and brookite crystalline phases, with brookite peaks more pronounced in samples synthesized with the IL. The TiO2 particles had high surface area, controlled porosity, narrow pore size distribution, high thermal stability, and spherical morphology. The particle size decreased with the use of the IL and increased with a higher precursor/alcohol ratio.

Summary: In this study, a metal-organic framework material called MIL-101 was synthesized and tested for the removal of low concentrations of benzene and toluene from a gas phase. Different models were used to analyze the breakthrough curves, and it was found that the Thomas model fit the benzene data best, while the Gompertz model fit the toluene data best. Nonlinear regression showed a stronger correlation with the experimental results compared to linear regression. Both liquid film and intraparticle diffusion were found to contribute to the adsorption mechanism. The Freundlich isotherm provided the best fit for the adsorption process. MIL-101 showed better reusability for benzene compared to toluene.
