Summary: Ionic liquids (ILs) are promising for digesting Lunar regolith and facilitating metal separation. We present a novel model using Support Vector Machine (SVM) to predict ILs solubility parameters and enable screening for regolith digestion. The results are validated by experiments and a Hansen Solubility Sphere analysis, providing valuable insights.

Summary: The selectivity of pesticide-cannabinoid extraction was studied using eight new polymeric ionic liquid sorbent coatings. The chemical structure modifications, such as the absence of aromatic moieties and the addition of hydrogen bond donor functional groups, were found to increase the selectivity. Solubility differences were also shown to play a dominant role in enhancing pesticide-cannabinoid selectivity.

Summary: Due to inefficient pi-complexation of Cu+ sites, current available cuprous-based liquid absorbents have limited CO solubilities, which are far from equimolar CO capture. In this study, a novel cuprous-based quaternary deep eutectic solvent (DES) was prepared and used as a superior absorbent for equimolar CO capture. The cuprous-based quaternary DES [Emim]Cl-CuCl-ZnCl2-EG exhibited a remarkable CO uptake capacity (0.934 mol/mol, almost equimolar CO capture) and good ideal selectivities for CO/N2, CO/CO2, and CO/H2, making it the best liquid absorbent for efficient CO absorption.

Summary: This study explores the use of ionic liquids as separation agents for the separation of HFC/HFO mixtures. The results show that ionic liquids can effectively absorb HFCs, with R-227ea showing the highest solubility. The absorption equilibria were successfully correlated using the measured data and the NRTL model, providing a theoretical tool for the design of separation processes.

Summary: Ionic liquids are promising solvents for the absorption of volatile organic compounds. By studying the effects of different structural features on solubility, potential solvents can be identified and the relationship between various interaction energy parameters and solubility can be determined. The study provides a fundamental basis and practical data for the control and treatment of VOCs.

Summary: Paramylon is a water insoluble linear glucan produced by Euglena gracilis microalgae. It has a stable triple helix conformation and high crystallinity due to its macromolecular structure containing only b(1-3) linkages. The solubility of paramylon was evaluated using eco-friendly ionic liquids as solvents, and the structure and thermal properties of the biopolymer before and after solubilization and regeneration were discussed.

Summary: Ionic liquids (ILs) are well-known for their CO2 capture properties. The combination of ILs with various materials reduces the problem of high viscosity of ILs. Encapsulated ionic liquid (ENIL) systems can overcome the low CO2 absorption rate and difficulties in solvent regeneration. This review comprehensively evaluates recent literature on ENILs for CO2 capture, including preparation, characterization, reaction kinetics, solubility, selectivity, and regeneration studies.

Summary: Noscapine and its derivatives have shown potential as cough suppressant, anti-cancerous activity, and ability to inhibit the main protease of SARS-CoV-2 and chikungunya. This study focused on designing ionic liquids composed of noscapinium cation with different anions, and analyzing their thermo-chemical data, IR and UV-visible spectra, and ADME behavior. The most soluble and stable ionic liquid among the designed ILs was found to be (R)-5-((S)-4,5-dimethoxy-3-oxo-1,3-dihydroisobenzofuran-1-yl)-4-methoxy-6,6-dimethyl-5,6,7,8-tetrahydro-[1,3]dioxolo[4,5-g]isoquinolin-6-ium trifluoromethanesulfonate (IL4) based on DFT calculations.
