Summary: Liquid-liquid extraction is an important industrial separation process for components with close boiling points. Experimental analysis of mixtures containing cyclohexane + benzene + DMF + KSCN showed that selectivity coefficient increases with salt mass, while distribution coefficient decreases with benzene concentration.

Summary: In this study, Co(OH)2 nanoparticles with a size smaller than 10 nm were prepared and incorporated into a mixed matrix membrane, resulting in improved separation performance. The well-distributed nanoparticles in the polymeric matrix could interact with benzene molecules, enhancing the separation performance for benzene. However, the performance of the membrane was weakened when the nanoparticles agglomerated.

Summary: A computer-aided ionic liquid design method was developed for the extractive separation of benzene/cyclohexane, resulting in the identification of promising IL [COC2MIM][Tf2N] with outstanding separation performance and favorable physical and environmental properties. Process simulation using the designed IL showed lower solvent consumption and heat duty compared to the benchmark organic solvent sulfolane, indicating [COC2MIM][Tf2N] as a promising alternative for the extractive separation of benzene/cyclohexane.

Summary: High porosity and large pore volume of MIL-101 MOF make it a potential material for membrane separation technology. By incorporating ILs within the cages and over the surface of MIL-101, the pore structure and surface properties were successfully tuned, leading to outstanding separation performance in mixed matrix membranes (MMMs). This study may inspire the design of high-performance MMMs by modifying porous nanomaterial microstructure.

Summary: Ionic liquids (ILs) have the advantages of being low cost, eco-friendly, abundant in heteroatoms, and having excellent solubility and coordination abilities with metal ions, making them suitable precursors for fabricating metal single-atom catalysts (SACs). In this study, various metal single atoms anchored on ultrathin N-doped nanosheets were prepared using ILs and g-C3N4 nanosheets as templates. The Cu-1/NC-1000 catalyst exhibited the highest catalytic activity for benzene oxidation to phenol, with a high benzene conversion rate of 82%, phenol selectivity of 96%, and excellent recyclability.

Summary: This study investigates the use of task-specific ionic liquids (TSILs) in the form of supported ionic liquid membranes (SILMs) for the separation and purification of dimethyl carbonate (DMC) through pervaporation. The results show that SILMs exhibit higher selectivity at low temperatures and an increase in temperature negatively affects the permeance of DMC and methanol.

Summary: In this study, ionic-liquids-decorated halloysite nanotubes (ILs@HNTs) composites were embedded into PDMS matrix to fabricate mixed matrix membranes (MMMs) for the selective pervaporation of ethyl acetate (EtAc) from aqueous solutions. The MMMs loaded with ILs@HNTs exhibited remarkable separation factors and high flux compared to pristine PDMS membranes, benefiting from the synergistic effect of highly permeable HNTs and highly selective ILs. Molecular simulations provided theoretical support for the experimental results, and the effects of different factors on the pervaporation performance of the MMMs were systematically investigated. The unique modification method developed in this study can be applied to other tubular materials and provides valuable guidelines for designing high-performance membrane structures.

Summary: In this study, mono- and bimetallic Pd and Pt catalysts were deposited via supercritical fluid reactive deposition (SFRD) on TiO2 coated additively manufactured substrates. The focus of this work was to evaluate the suitability of these catalysts for the direct synthesis of H2O2 in the liquid phase. The results showed that all catalysts exhibited high activity and productivity, with PdPt bimetallic catalysts showing the highest productivity and an increase in Pd loading leading to a decrease in productivity. Comparison with literature data demonstrated the high suitability of the SFRD method for the proposed application, with the added benefits of simplicity and environmental friendliness in catalyst production.

Summary: It is impossible to control the outer wall temperature of the micro-combustor below the maximum allowable temperature of commercial thermoelectric generators simply through increasing the equivalent heat transfer coefficient. Three simple strategies were developed to improve temperature uniformity, yet none of them could ensure full temperature control.
