HighlightsWhat are the main findings?[Bmim][ClO4] increased heavy-oil recovery in toluene and xylene systems.[Bmim][ClO4] reduced recovered-oil viscosity and improved flowability.[Bmim][ClO4] lowered contact angle and weakened oil–solid adhesion.What are the implications of the main findings?[Bmim][ClO4] is a promising additive for heavy-oil extraction.Interfacial regulation is key to improving heavy-oil separation efficiency.Preferential interaction with resins/asphaltenes explains enhanced recovery.Separating heavy oil from solid matrices is still difficult, mainly because of the strong adhesion between oil and solids and the intrinsically high viscosity of heavy oil, both of which restrict efficient large-scale recovery. Ionic liquids have recently attracted attention as additives that may improve extraction performance. In this work, [Bmim][ClO4] was introduced into toluene- and xylene-based solvent systems to examine its role in heavy-oil recovery. The extraction performance was evaluated through recovery yield, viscosity, contact angle, oil–solid interaction force, and SARA composition. Molecular dynamics simulation was also carried out to probe how [Bmim][ClO4] interacts with heavy-oil components and how it influences the diffusion of saturates, aromatics, resins, and asphaltenes. The results show that the addition of [Bmim][ClO4] improved heavy-oil recovery in every solvent system tested, with the highest value, 89.31 wt%, obtained in the toluene system. At the same time, the ionic liquid lowered the viscosity, reduced the contact angle, and weakened the adhesion between the oil phase and the solid surface, all of which favored oil–solid separation. SARA analysis further indicated that the extraction of heavier fractions, especially resins and asphaltenes, became more pronounced after adding the ionic liquid. Simulation results suggest that [Bmim][ClO4] interacts more strongly with resins and asphaltenes, disrupts their associated structures, and facilitates mass transfer. Taken together, these results suggest that [Bmim][ClO4] improves heavy-oil extraction by altering interfacial behavior and loosening the aggregated structure of heavy fractions, which may be useful for future process optimization.

Oral delivery of peptide therapeutics remains challenging due to gastrointestinal degradation, poor epithelial permeability, and extremely low bioavailability. To address these limitations, we developed an enteric solid formulation based on sorbic acid–choline ionic liquids (ILs) for the oral delivery of semaglutide (Sema), a glucagon-like peptide-1 (GLP-1) analogue. The IL-based enteric system was designed to enhance peptide stability, reduce gastric degradation, and promote intestinal absorption. In vitro studies demonstrated strong resistance to acidic conditions and pH-responsive release in simulated intestinal fluid. In vivo imaging further revealed prolonged intestinal retention of the IL-loaded enteric particles. Pharmacokinetic evaluation showed a 2.3-fold increase in maximum plasma concentration compared to the reference Rybelsus. In type 2 diabetes mellitus (T2DM) mice, the formulation achieved glucose-lowering efficacy comparable to subcutaneous Sema administration, with additional improvements in hepatic histology. Importantly, repeated-dose studies indicated favorable systemic and gastrointestinal tolerability under the tested conditions. Collectively, these results demonstrate that IL-based enteric formulation enhances oral peptide exposure while maintaining safety, offering a promising strategy for noninvasive T2DM management.

An ionic liquid-functionalized liquid metal based polyurethane/hydrogel composite coating was successfully prepared. • The hydrogels displayed excellent antifouling activity, with antibacterial rates of 95% and anti-algal inhibition of 98%. • The hydrogels demonstrated excellent mechanical properties and self-healing capability, reaching 96.9% healing efficiency. Marine biofouling incurs substantial economic losses. Among various strategies, hydrogels are regarded as effective antifouling materials due to their high hydrophilicity and low adhesion. However, their swelling nature often affects the mechanical performance, limiting their practical antifouling applications. In this study, a hydrogel composite was developed by incorporating ionic liquid-functionalized liquid metal nanofillers into a waterborne polyurethane-based hydrogel matrix to achieve enhanced antifouling and mechanical performance. The imidazolium ionic liquid containing a silane coupling agent was successfully grafted onto the liquid metal surface via a self-assembly process, and the resulting functionalized liquid metal was subsequently incorporated into a waterborne polyurethane/acrylic acid (PUGel) hydrogel matrix. The prepared TIm-GLM@PUGel exhibited outstanding comprehensive performance, achieving antibacterial rates of 87% against E. coli and 95% against S. aureus , as well as anti-algal rates of 98% against Dunaliella and 88% against Porphyridium . Moreover, the composite hydrogels demonstrated significantly improved mechanical behavior, with a tensile strength of 1.09 MPa and an elongation at break of 1059.8%. Notably, the TIm-GLM@PUGel showed remarkable self-healing performance, with a healing efficiency of 96.9%. This strategy offers a viable route toward high-performance and environmentally benign antifouling coatings. Download: Download high-res image (113KB) Download: Download full-size image

To develop high-performance anion exchange membranes (AEMs) with excellent alkaline stability and high hydroxide conductivity, a series of poly(styrene-co-4-vinylpyridine) (PSD-m/n) were rationally designed and synthesized. Based on mature synthetic strategies, this work optimized a superior molecular configuration. The prepared polymers possess a flexible all-carbon backbone and adopt a side-chain grafting strategy to anchor industrial ionic liquids. Such aryl ether-free membrane architecture can effectively suppress the alkaline degradation behavior of conventional AEMs under harsh working conditions. Target quaternized AEMs (QPSD-m/n) were successfully fabricated by reacting PSD-m/n with an industrial ionic liquid 3-Bromo-N,N,N-trimethylpropan-1-aminium bromide (abbreviated as BTPA, counterion: Br − ). The content of pyridine-functionalized segments in the polymer backbone was precisely tailored by adjusting the molar feed ratio of styrene to 4-vinylpyridine, enabling a systematic investigation of the membrane structure-property relationship. The optimized QPSD-m/n AEMs exhibit desirable ion exchange capacity (IEC) of 1.53-2.13 meq g −1 , show low water uptake (WU) (15.22-31.03%) and restrict swelling ratio (SR) (10.11-23.90%) at 80 °C. The membranes achieve a high hydroxide conductivity of 58.32-90.06 mS cm −1 at 80 °C under test conditions. Moreover, the QPSD-m/n AEMs possess excellent thermal stability and optimizable alkaline durability. This work demonstrates that the QPSD-m/n membranes exhibit favorable performance and hold promising application prospects.

A conducting polymer based composite material of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with pure insoluble ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, was prepared through a cost-effective electrodeposition method. A very tiny amount of insoluble IL (less than 15 μL), containing 0.1 M conducting polymer monomer, was drop-coated on an electrode surface and then used for electropolymerization using a homemade electrochemical cell filled with aqueous supporting electrolyte. With this design, the consumption of expensive IL for the preparation of the PEDOT/IL composite was greatly reduced, and thus effectively reduced the cost. The prepared PEDOT/IL composite was found to be highly conductive and stable, and it exhibited a highly nanoporous microstructure and excellent electrocatalytic activity toward the oxidation of dopamine (DA). Based on the excellent stability and electrocatalytic activity of the PEDOT/IL nanocomposite, a highly stable, sensitive and selective DA sensor with a detection limit of about 51 nM was developed.

Based on amino polybenzimidazoles with flexible hydrophilic side chains (AmPBI-MOE) and polymeric ionic liquid (PIL), a series of composite membranes (AmPBI-MOE-PIL-X) were fabricated for vanadium redox flow battery applications. Here, 1-Bromo-2-(2-methoxyethoxy)ethane was grafted onto amino polybenzimidazole (AmPBI) by the method of halogenated hydrocarbons, and PIL was synthesized from ionic liquids by in situ radical polymerization to build a hydrogen-bonded cross-linked network within the film. The hydrophilic side chain improves the proton conductivity. With the increase in ionic liquids, the vanadium transmittance and the proton conductivity increase. The AmPBI-MOE-PIL-5 membrane not only exhibits a vanadium ions permeability of 0.88 × 10−9cm2min−1, which is much lower than Nafion117 (6.07 × 10−8cm2min−1), but also shows a very excellent blocking ability for vanadium ion. The AmPBI-MOE-PIL-5 membrane shows excellent performances at 60 mA cm−2, with VE of 87.93% and EE of 82.87%, both higher than that of Nafion117 membrane in VRFB.

Efficient adsorption and selective separation of ammonia at high temperature is a crucial and challenging issue. In this work, a series of stable ionic liquid hybrid materials have been developed by simple impregnation of ionic liquids into stable metal–organic framework Al-fum with 1D pores. The hybrid material [C 2 N][Zn 3 Cl 7 ]@Al-fum-60% exhibited an exceptionally high uptake (9.9 mmol/g at 80 °C, 8.8 mmol/g at 100 °C) at high temperature, excellent uptake (9.8 mmol/g at 25.0 °C) at low ammonia concentration (100,000 ppm), and remarkable selective separation performance (selectivity factor is 25.1) of NH 3 from NH 3 /CO 2 mixture at high temperature. The NH 3 uptake of [C 2 N][Zn 3 Cl 7 ]@Al-fum-60% at 100 °C was higher than the capacity of most of typical porous NH 3 adsorbents at room temperature. It is revealed that such superior NH 3 capacity and selective separation performance are mainly attributed to coordination interactions of NH 3 to Zn centre of the ionic liquids and the hydrogen bonding interactions of NH 3 with Cl of the ionic liquids and NH 3 with μ-OH of Al-fum.

A low-energy plasma electrolytic oxidation (LePEO) technique is developed to simultaneously improve energy efficiency and anti-corrosion. Ionic liquids (1‑butyl‑3-methylimidazole tetrafluoroborate (BmimBF 4 )) as sustainable corrosion inhibitors are chosen to investigate the corrosion inhibition behavior of ionic liquid (ILs) during the LePEO process for LA91 magnesium–lithium (Mg–Li) alloy. Results show that the ionic liquid BmimBF 4 participates in the LePEO coating formation process, causing an increment in coating thickness and surface roughness. The low conductivity of the ionic liquid is responsible for the voltage and breakdown voltage increases during the LePEO with IL process (LePEO-IL). After adding BmimBF 4 , corrosion current density decreases from 1.159 × 10 −4 A·cm −2 to 8.143 × 10 −6 A·cm −2 . The impedance modulus increases to 1.048 × 10 4 Ω·cm −2 and neutral salt spray remains intact for 24 h. The superior corrosion resistance of the LePEO coating assisted by ionic liquid could be mainly attributed to its compact and thick barrier layer and physical absorption of ionic liquid. The ionic liquid-assisted LePEO technique provides a promising approach to reducing energy consumption and improving film performance.

Titanium disulfide nanosheets (TiS 2 NSs) have attracted considerable research interest due to their eco-friendliness and outstanding electrical transport properties. However, the large scale preparation of TiS 2 NSs usually is plagued by the employ of poisonous solvents and low production. Herein, we develop a green, highly efficient and scalable tactic to exfoliate bulk TiS 2 powders in aqueous ionic liquids solutions under ambient conditions. This result shows that the exfoliation yield can reach 57.6 %, which surpasses the most values for the liquid-phase exfoliation of TiS 2 reported in literatures. The thickness of TiS 2 NSs is mainly in the range of 1 nm to 2 nm, and the lateral dimension is up to a few hundreds of nanometers. The molecular geometry and anionic alkalinity of the ionic liquids play key roles in the delamination and stability of TiS 2 NSs. In addition, TiS 2 NSs have been used as catalysts in the electrocatalytic CO 2 to CO conversion with the faradaic efficiency of 68.7 %, which is six times that by the bulk TiS 2 powder. Thus, the liquid phase delamination approach reported in this work has a great potential in manufacturing 2D layer materials for high activity electrocatalysis.

To ensure the safety of drugs in clinical use and avoid side effects, the impurity content should be strictly controlled. Artemisitene (ARE) has quite similar structure to that of the antimalarial artemisinin, and thus is difficult to be removed from the target drug. The traditional column chromatography method to purify artemisinin has low separation efficiency and needs lots of organic solvents. In this work, functional ionic liquid (IL), 1-(trimethoxysilyl) benzene-3-vinylimidazolium chloride, modified silica materials were synthesized. Composition of the functional materials were characterized by energy dispersive spectroscopy, FT-IR, and X-ray photoelectron spectroscopy. It was indicated that the designed ionic liquid was successfully grafted onto SiO 2 . Adsorption capacity of the prepared ionic liquid-based material for artemisinin and artemisitene was evaluated, and it was demonstrated that adsorption of ARE by the functional material was a quick process, and the adsorption kinetics followed the Elovich Model. This kind of IL@SiO 2 material exhibited excellent performance in selective separation of artemisitene from artemisinin. Mechanism exploration by spectroscopic analysis revealed that π-π conjugated interactions between the unsaturated bond (the C=C bond and aromatic ring) in the ionic liquid and artemisitene enhanced the molecular recognition capability of IL@SiO 2 for ARE, resulting in selective separation of these two structurally analogues.

In this work, we designed a novel thermally stable Zn bromide-based deep eutectic ionic liquid (DEIL), synthesized from tetralkylphosphonium bromide (Bu 4 PBr) and ZnBr 2 by a facile heating method. The structural changes and the physical properties of the catalyst were in-depth investigated. Among all the DEILs, ZnBr 2 ·2Bu 4 PBr showed high activity, achieved 98.2% propylene carbonate (PC) yield at a low catalyst usage (0.15 mol%), and remained good stabilities for 8 cycles. Furthermore, based on experimental results and DFT calculations, we found that Bu 4 P + cation of DEIL served as a frame charge-balanced species interacting with three possible anions of ZnBr 4 2− , ZnBr 3 − and Br − . The interaction is accompanied by a reversible pre-equilibrium in which [Bu 4 P] 2 [ZnBr 4 ] could dissociate and produce the true catalytically active species, [Bu 4 P][ZnBr 3 ] and Bu 4 PBr. Meanwhile, a possible ring-opening mechanism was proposed, in which the synergetic effect of cations and anions in the catalytic system can promote ring-opening. The significance of this study is that it provides guidance for developing metal bromide-based DEILs for carbonate synthesis.

Non-precious metal catalysts show great promise to replace the state-of-the-art Pt-based catalysts for catalyzing the oxygen reduction reaction (ORR), while their catalytic activity still needs to be greatly improved before their broad-based application. Here, we report a facile approach to improving the performance of zeolitic imidazolate framework-derived carbon (ZDC) toward the ORR by incorporating a small amount of ionic liquid (IL). The IL would preferentially fill the micropores of ZDC and greatly enhance the utilization of the active sites within the micropores, which are initially not accessible due to insufficient surface wetting. It is also disclosed that the ORR activity in terms of kinetic current at 0.85 V depends on the loading amount of the IL, and the maximum activity is obtained at a mass ratio of IL to ZDC at 1.2. The optimum stems from the counterbalance between the enhanced utilization of the active sites within the micropores and the retarded diffusion of the reactants within the IL phase due to its high viscosity.
