Summary: Interfacial tension (IFT) and wettability are important factors in determining oil/water distributions and hydrocarbon production in reservoirs. This study investigates the effects of ionic liquids (ILs) on IFT and wettability in sandstone reservoirs. The results show that ILs can lower alkane-water IFT and influence the interaction between oil droplets and the quartz surface. Molecular dynamic simulations indicate that ILs can reduce the interaction energy between octane droplets and the quartz surface. These findings have promising applications in enhanced oil recovery and oil contamination removal.

Summary: The study aimed to investigate the physicochemical and biological behavior of ionic liquids with different counter ions in the presence of an antibacterial drug, ciprofloxacin. The spontaneous interaction between ILs and CIP, increase in ILs aggregates size in presence of CIP, and the improvement in antibacterial activity of CIP in the presence of imidazolium ILs were observed. The results highlight the importance of ILs in pharmaceutical industries.

Summary: In this study, the surface and interface tension measurements of two ionic liquids were reported. A newly developed experimental setup was used to perform the measurements under high vacuum conditions. The results showed that the surface tension varied under different conditions, which is important for understanding the microscopic parameters determining surface tension and for benchmarking theoretical calculations.

Summary: A new strategy for direct access to fully substituted polycyclic imidazolium salts using alpha-enaminones and proline as the reagents is reported. This open-flask operation is a catalyst-, metal-, and Lewis acid-free green process, which does not require an ion-exchange step. It can produce good yields with minimal formation of side products, and is not limited to aryl substituents.

Summary: This study systematically investigated the interfacial interactions and structures of imidazolium-based ILs on black phosphorus surfaces, revealing that adsorption is dominated by strong electrostatic interactions, weak van der Waals forces, and other interactions. The length of the alkyl chains in the cation plays a significant role in tuning the adsorption behaviors, and differences between protic and aprotic ILs were also examined.

Summary: Ionic liquids (ILs) have been widely used but difficult to purify and recycle due to their hydrophilicity. This study calculated the free energy of water crossing ILs and found a linear relationship between surface tension and water content at the interface. The nonlinear change of surface tension with total water content was explained by investigating the interface structure with water content.

Summary: This study investigates the effects of a benzimidazolium cationic GSAIL and SDS surfactants on the properties of crude oil-water interface. Synergistic effects were observed in reducing interfacial tension (IFT), promoting emulsification, and altering wettability. The attractive interaction between the cationic GSAIL and the anionic SDS contributes to the remarkable performance.

Summary: The micellization and microstructure of mixed micelles from mixtures of anionic and cationic surfactants were extensively studied, showing low CMC and large negative interaction parameter values due to synergism in the mixed systems. The thermodynamic parameters for mixed monolayers and micelles were evaluated. The influence of the ILs on micellar growth, shape changes, and transitions to vesicles was dependent on the surface activity of ILs.

Summary: Interfacial issues hinder the progress of current solid-state battery technology, and interface engineering approaches are needed to achieve solid-state configuration. Ionic liquids, which are viscous and nonflammable, can optimize the interface between solid electrodes and solid electrolytes, accelerate ion transport at the interface, and create engineered interphases using robust chemical building blocks. This review summarizes the roles of ionic liquids in solid-state batteries, with a focus on the interface, and highlights their functionality and applicability in next-generation battery systems.

Summary: This study introduces a series of vinyl-imidazolium-based polyelectrolyte composites modified with multivalent imidazolium-benzene ionic liquids or crosslinked with novel cationic crosslinkers. The composites exhibited enhanced CO2 permeabilities and selectivities against N-2 or CH4, demonstrating the potential for tuning the properties and transport behaviors of ionic polymers using ionic liquid-inspired small molecules.

Summary: This paper describes the corrosion inhibiting action of four new imidazolium-derived ionic liquids (ILs). Various analytical techniques were used to confirm their molecular formula and characterize their adsorption behavior on a steel substrate. Results showed that these ILs exhibited effective corrosion suppression and adsorbed onto the steel surface through physi-chemisorption. SEM/EDX and FTIR analysis further supported the adsorption process of the ILs.

Summary: Through DFT computational study, it was found that imidazolium and pyridinium based ionic liquids exhibit good anticorrosive potential, with corrosion inhibition performance depending on the nature of alkyl groups and halide ions. Among the studied ionic liquids, certain compounds were found to show the best corrosion inhibition performance in both imidazolium and pyridinium based categories.
