Summary: This study investigates the lubrication behavior of ionic liquids (ILs) as lubricant additives through experiments and molecular dynamics simulation. The results show that ILs with short-chain anions exhibit better lubricating performance, which is attributed to the formation of a denser protective layer that promotes tribochemical reactions at the frictional interface.

Summary: The structure, active sites, and adsorption mechanism of imidazole-based ionic liquids on the Pt(1 1 1) surface and their effects on aluminum electrodeposition were evaluated by first-principles approaches. The longer alkyl chain of the ionic liquids increased the coverage of cations on the Pt(1 1 1) surface and the number of charge transfers, and decreased the distance between chlorine atoms and the Pt(1 1 1) surface. This suppresses dendrite formation and promotes deposition of aluminum in smaller sizes. These results will aid in selecting efficient ionic liquids for aluminum electrodeposition.

Summary: Increasing side chain length of the studied ammonium-based polymerized ionic liquids results in lower glass transition temperatures and higher ionic conductivity values. However, the addition of conducting salt to the polymer membranes decreases both the glass transition temperatures and the ionic conductivity values, while higher lithium-ion mobility is observed in samples with higher conducting salt content.

Summary: Ionic liquids (ILs)-based membranes, such as Pebax blended membranes with ILs [EtOHmim] [NTf2] and [EtOHim] [NTf2], show improved NH3 separation performance due to hydrogen bonding interaction and moderate interaction between ILs and NH3 molecules. The introduction of ILs significantly enhances NH3 selectivity and permeability in the membranes. The study highlights the importance of moderate interaction between ILs and NH3 molecules for effective NH3 separation.

The results showed that the stability, crystallinity, and digestion resistance of the complexes increased with increasing alkyl chain length of ARs. V6-amylose-ARs inclusion complexes exhibited the highest stability, crystallinity, and lowest digestibility compared to other complexes.

Summary: Supported nicotine-based IL membranes were synthesized to investigate the effect of alkyl chain length and ether groups on physicochemical properties and gas/water vapor separation. Gas permeation was influenced by diffusion, while solubility played a major role in water vapor permeation. Increasing alkyl chain length enhanced gas permeabilities via reduced IL viscosity, but decreased water vapor permeability due to increased hydrophobicity. In contrast, membranes with IL containing ether groups showed the highest water vapor permeability and selectivity, making them suitable for dehumidification processes even under mixed gas/water vapor conditions.

Summary: The solvation behavior and thermophysical properties of protic ionic liquids (PILs) in other polar solvents have been studied. The density and speed of sound of binary mixtures of a PIL, ethyl ammonium nitrate (EAN), with diethylene glycol (DEG) and its derivatives were measured. Various thermodynamic parameters were determined and discussed, and the role of different functional groups in governing the thermophysical properties was analyzed. Density Functional theory (DFT) calculations were employed to explain the variation in excess molar properties.

Summary: The emergence of COVID-19 has resulted in significant morbidity and mortality, with around seven million deaths worldwide as of February 2023. Age and sex are risk factors associated with severe symptoms in COVID-19, but there is limited research on sex differences in SARS-CoV-2 infection. This study explores sex-specific molecular factors in mouse and human datasets to identify potential links with the SARS-CoV-2 host receptors ACE2 and TMPRSS2 and highlights the importance of assessing sex differences for optimal treatment and vaccination strategies.

Summary: The impact of an imidazolium-based ionic liquid (IL) on model cell membranes with and without cholesterol has been studied. The IL reduces the area of the cholesterol-free membrane and increases the elasticity of the cholesterol-containing membrane. X-ray reflectivity measurements confirm the formation of IL-induced phase-separated domains in the pure lipid phase. These results suggest that IL may deform bacterial cell membranes without cholesterol, but may not be harmful to human cell membranes due to the presence of cholesterol.
