An MP-IL dual-network hydrogel sensor is developed from chicken by-products. • It offers skin-matched modulus, high conductivity, and wide-range dmotion monitoring. • The hydrogel shows high biocompatibility with no inflammatory response. • The hydrogel shows negligible IL leakage and stable 200-cycle performance. • This MP-based e-skin uniquely integrates biosafety and and biodegradability. Biocompatible sensors with tissue-like mechanical properties are urgently needed for individuals with communication and movement disorders. Conductive hydrogels are promising candidates, yet conventional synthetic versions face biosafety and degradability challenges for long-term wearable use. In this work, we developed a biocompatible dual-network hydrogel sensor for high-performance epidermal sensing, integrating the skin-homologous myofibrillar proteins (MP) with ionic liquid (IL) through unique molecular design. The hydrogel network is constructed via Schiff-base crosslinking between MP and oxidized dextran (ODex), interpenetrated with an ionically cross-linked sodium alginate (SA) network. This unique design achieves skin-matched mechanical properties (tensile strength 440.4 ± 16.6 kPa, elastic modulus 342.5 ± 12.2 kPa) and high ionic conductivity (9.1 mS/cm). The resulting sensor exhibits excellent strain response (0.4 s) and recovery (0.2 s) times, high sensitivity (gauge factor ~ 1.55), and stable resistance variation under both tensile and compressive deformation, showing potential for monitoring a wide range of motions from subtle physiological signals (e.g., frowning, swallowing, and smiling) to large-scale joint movements, speaking, and handwriting signal monitoring, with possible relevance to throat motion monitoring and assistive communication. The ionic liquid shows negligible leakage (<5% cumulative release over 7 days), and the hydrogel maintains stable mechanical performance over 200 cyclic loading-unloading tests, supporting long-term wearable reliability. In vitro cytotoxicity, in vivo skin patch, and implantation tests confirm excellent biocompatibility (cell viability ≥94.2%) with no significant inflammatory response. Sourced from low-cost chicken meat by-products, this hydrogel provides an alternative platform for next-generation epidermal electronics that harmonizes biosafety and biodegradability.

Emulsified oily wastewater is difficult to separate because of the small droplet size and high interfacial stability of emulsified droplets. Herein, a series of porous poly(ionic liquid)s (PILs) with tunable wettability and pore structures were synthesized through Friedel-Crafts crosslinking reactions using cyanuric chloride and imidazole-derived ionic liquid monomers. By regulating the co-crosslinkers and crosslinkers, the surface wettability and porous architectures of the PILs were effectively tailored. The obtained materials exhibited either hydrophobic and oleophilic properties or hydrophilic and underwater oleophobic properties, enabling the selective separation of stratified oil-water mixtures and emulsified oil-water systems. For emulsified oil-water systems, the separation efficiencies exceeded 97%, with a maximum flux of 940 L·m −2 ·h −1 , while separation efficiencies above 99% and a maximum flux of 9251 L·m −2 ·h −1 were achieved for stratified oil-water mixtures. The results indicate that the co-crosslinkers primarily regulate surface wettability, whereas the rigid crosslinker promotes the formation of larger pore volumes and more efficient transport pathways, thereby enhancing permeation performance. This work establishes a structure-property relationship between co-crosslinker chemistry, pore architecture, and separation performance, providing a new strategy for the rational design of porous PIL-based oil-water separation materials.

Rapid detection of tryptophan (Trp) enantiomers has been a research hotspot in pharmaceuticals, life sciences, and related fields. Herein, N, S-doped carbon dots (N, S-CDs) and chiral ionic liquid (CIL) were used to functionalize the glassy carbon electrode (GCE), constructing a simple electrochemical sensor (N, S-CDs/CIL/GCE) for the efficient recognition of Trp enantiomers. CIL not only provides a chiral microenvironment but also synergistically amplifies electrochemical signals through electrostatic interactions with N, S-CDs, while enhancing interfacial electron transfer efficiency. Differential pulse voltammetry (DPV) analysis indicates that with an 8.0 μL loading volume and pH 6.0, the N, S-CDs/CIL/GCE achieves the maximum enantiomeric selectivity coefficient ( I L / I D = 2.12) for L-Trp versus D-Trp. Moreover, it exhibits excellent stability and shows high selectivity toward Trp enantiomers even in the presence of common interfering substances, with detection limits of 0.035 mM and 0.084 mM for L-Trp and D-Trp, respectively (1.5 to 3.5 mM). Mechanistic investigations suggest that the DPV signal difference may stem from the stereoselectivity of N, S-CDs/CIL toward tryptophan isomers, as its affinity for L-Trp is higher than for D-Trp. Furthermore, the N, S-CDs/CIL/GCE exhibits significant potential for distinguishing amino acid isomers in non-racemic mixtures. This study offers new insights into the development of chiral compound sensors and bioanalytical strategies. Graphical

Programmable shape memory poly(ionic liquid) composites were prepared. • Composites integrate multifunctionality via network design within a single platform. • Composites exhibit shape memory, photothermal, antimicrobial and sensing performance. • BE 0.8 P 0.5 can serve as soft actuators with real-time monitoring of the process. • BE 1.6 P 0.5 can function as wearable devices for fracture management and monitoring. The progress in soft materials that intrinsically integrate actuation, sensing, and functional responsiveness is critical for advancing wearable electronics, soft robotics, and adaptive systems. Here, we report a multifunctional poly(ionic liquid) (PIL)-based composite that achieves this integration through rational molecular and network design. The composite was fabricated through UV-induced polymerization of 1-vinyl-3-butylimidazolium bromide (BVIM[Br]) and poly(ethylene glycol) diacrylate. PEDOT:PSS was incorporated to form a synergistic ionic-electronic conductive network and photothermal responsive performance. The switching temperature was programmable via precisely tailoring the polymer network architecture. Thus, the material can operate across distinct regimes from robust light-driven actuation to body-relevant conditions. The optimized composite exhibited excellent multi-stimuli-responsive shape memory behavior with high fixation and recovery ratios (>95%), rapid photothermal actuation capable of lifting 980 times its own weight, and intrinsic electromechanical coupling that allows real-time resistance feedback. At physiologically relevant trigger temperatures, the material also demonstrated intrinsic antibacterial activity (>99% inhibition), favorable cytocompatibility, and reliable strain sensing performance, supporting stable biointerface operation. Based on these properties, a fracture fixation ring was constructed, combining adaptive shape memory immobilization, localized photothermal therapy, and real-time motion monitoring within a single platform. This study establishes a generalizable strategy for designing soft materials with intrinsically coupled mechanical, electrical, and biomedical functionalities. This composite offers a versatile platform for applications spanning wearable devices, human-machine interfaces, soft robotics, and therapeutic systems.

Tough ionogels are developed via doubly ionic H-bond networks between polyacrylic (PAA) and protic ionic liquid [DBUH][Triz]. • The ionogel achieves superior fracture strength (24.3 MPa) and toughness (94 MJ·m −3 ). • Excellent dry resistance, temperature tolerance, and solvent-dependent swelling behavior. • High sensitivity and durability enable the ionogel to precisely detect diverse human motions. • Molecular insights are provided for designing mechanically tough and environmentally stable ionogels. The inherent trade-off between structural flexibility and mechanical robustness, along with difficulties with long-term environmental compatibility, severely limits the practical use of ionogels in flexible electronics. To address these limitations, we present the design of doubly ionic hydrogen bond networks and the fabrication of highly tough ionogels. These strong physical interactions are engineered by integrating poly(acrylic acid) (PAA) with a protic ionic liquid (PIL) synthesized from 1,8-diazabicyclo[5.4.0]undec-7-ene and 1,2,4-triazole. Governed by hydrogen bonds and ionic interactions, the optimized ionogel achieves remarkable mechanical performance, exhibiting a maximum tensile strength of 24.30 MPa, a fracture strain of 480%, and an exceptional toughness of 93.95 MJ·m −3 . Moreover, the ionogel demonstrates excellent anti-drying and solvent-dependent swelling behavior, as well as thermal tolerance and strong adhesion. As a flexible strain sensor, the ionogel exhibits high sensitivity and excellent electrical signal stability, enabling the reliable capture of human motion signals. The work establishes a promising strategy for fabricating mechanically robust ionogels via creating doubly ionic hydrogen bond networks. It also provides new insights for advanced flexible sensors adaptable to dry and harsh working conditions. Download: Download high-res image (176KB) Download: Download full-size image

Comprehensive Summary Electrocatalytic two-electron oxygen reduction reaction (2 e – ORR) represents a green and sustainable way for H 2 O 2 production, while its practical applications in industry are largely hindered by the unwieldy proton transfer kinetics. Herein, we develop a biomimetic interface engineering strategy to precisely regulate proton transfer kinetics for enhanced 2 e – ORR. Using atomically precise Au 25 ( p -MBA) 18 nanoclusters (NCs, p -MBA = 4-mercaptobenzoic acid) as model catalysts, we introduced a series of quaternary ammonium ionic liquid (IL) cations onto the cluster surface via combined electrostatic and π-π stacking interactions. The hydrophobic tails and controlled hydrolysis of IL cations disruptthe long-range interconnected hydrogen-bonding networks, which are ubiquitous in alkaline electrolytes and bring about an overwhelming proton transfer rate. Instead, a mild biomimetic proton relay mechanism favoring 2 e – ORR can be established and fine-adjusted, leveraging deprotonation and protonation equilibrium of IL cations. By this way, the optimized system can bring down the mean electron transfer number ( n ) to 2.45 and promote the H 2 O 2 selectivity to 90% or higher, evidencing a pronounced shift toward the 2 e – ORR pathway under alkaline conditions. This work underscores the usefulness of atomically precise interfacial engineering in optimizing the electrocatalytic performance of inorganic nanocatalysts.

Graphitic carbon nitride (CN), a promising photocatalyst for CO2 reduction, suffers from inefficient light harvesting and sluggish charge separation dynamics, which severely restricts its application. Ionic liquids (ILs) have been used for the assisted preparation of photocatalysts, thus effectively altering their geometric and electronic properties. Herein, the 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF6) IL was introduced as a modifier to successfully construct a P- and F-co-doped porous CN catalyst via simple calcination of the IL and urea without any organic solvents and templates. The optimized catalyst exhibited an enhanced photocatalytic activity for CO2 reduction via gas–solid mode under visible light irradiation, achieving CO and CH4 evolution rates of 39.9 and 2.63 μmol g−1 h−1 (CO selectivity of 94%), which were 7.8 and 4.8 times higher than those of pristine CN, respectively. PFCN also demonstrated excellent reusability and stability. Comprehensive characterization revealed that the strategy of doping of P and F atoms significantly enlarged the surface area, improved CO2 adsorption, broadened visible-light harvesting, and accelerated charge transfer and separation efficiency. This work highlights the potential of ILs as multifunctional agents for designing high-performance doped CN photocatalysts.

The metal wire mesh was utilized as a support to prepare θ-ring packings with a porous epoxy resin layer firstly. Then, phosphotungstic acid ionic liquid was synthesized by 1-vinyl-3-propylsulfonic acid imidazolium salt and phosphotungstic acid, and it was loaded onto the porous epoxy resin layer of the θ-ring packing so that the supported catalytic θ-ring packing for reactive distillation was acquired finally. This supported catalytic θ-ring packing was evaluated by the esterification of ethyl lactate in a laboratory-scale reaction distillation column and its catalyst kinetics were determined. Experimental results demonstrated that this packing exhibited good catalytic ability and stability. With 2.65 g phosphotungstic acid ionic liquid catalyst, the conversion rate of lactic acid surpassed that of the tea bag packing containing 8.94 g Amberlyst-15 ion exchange resin catalyst. In addition, a reactive distillation production process for 99 wt% ethyl lactate was established and simulated, and results showed that in comparison with the KATAPAK-SP12 structured catalytic packing, this supported catalytic θ-ring packing can reduce the total annual costs of the reaction distillation column by 46.0% and the overall process by 29.1%.

The conversion of readily accessible chemicals into high-value-added products is a key process in industrial chemistry. This research showcases an efficient transformation of benzyl alcohol to benzaldehyde utilizing poly(ionic liquid)s (PILs) supported Pd-based catalysts. The catalyst’s properties were thoroughly characterized using FT-IR, SEM, TEM, XPS, and TG, confirming the successful fabrication of stable Pd/PILs catalysts. The porous architecture of the PILs material enhances palladium nanoparticle adhesion, while its structure promotes intimate contact between the catalyst and substrate, facilitating the oxidation process. With just 0.1 g of 1 % Pd/PIL-2 catalyst, the reaction at 110 °C, 4 MPa O 2 for 4 h achieve a 82.16 % conversion of benzyl alcohol with absolute selectivity to benzaldehyde. Theoretical calculations elucidated the interactions between Pd 6 clusters, PIL, and benzyl alcohol. Furthermore, the Fukui function and optimized electrostatic potential diagrams identified reactive sites, providing insights into the potential reaction mechanism.

The construction of stable electrode/electrolyte interphases (EEIs) is crucial for the development of practical lithium metal batteries (LMBs). In this work, we designed locally concentrated ionic liquid electrolytes (signed as FPB2) based on 1,3,5-trifluorobenzene (3FB) diluent to address this challenge. The appropriate addition of 3FB encourages Li+ association with anions, creating a significant amount of anion-dominated aggregate-II solvation structure, which enables profound anion decomposition and rapid Li+ transport. In parallel, the low lowest unoccupied molecular orbital of 3FB allows for its own reductive decomposition on the lithium metal anode (LMA) surface. Benefiting from the synergistic decomposition of anions and 3FB, a uniform and stable solid electrolyte interphase (SEI) is formed on the LMA. Additionally, a thin cathode electrolyte interphase (CEI) abundant in LiF is generated on the LiFePO4 (LFP) cathode, resulting in the effective suppression of electrolyte oxidation. This dual-interphase stabilization endows impressive cycling performance in a Li/LFP full battery under demanding conditions (10.8 mg·cm–2 LFP, 50 μm Li) to achieve 81.5% capacity retention and 99.4% average Coulombic efficiency over 200 cycles. This work presents a new paradigm for electrolyte design in high-performance LMBs by exploiting a functional diluent to proactively stabilize dual EEIs.

Li 7 La 3 Zr 2 O 12 (LLZO)-based solid-state lithium-metal batteries (SLBs) are strong candidates for next generation high specific capacity and high safety energy storage devices. Unfortunately, poor interfacial contact between the cathode and the solid-state electrolyte (SSE) severely limits the practical application of SLBs. Here, a pyrrole-based (1-Butyl-1-methyl pyrrolidinium Bis (trifluoromethanesulfonyl) imide) ionic liquid (BMP-IL) electrolyte interlayer is used to address this issue. The IL interlayer provides a fast Li + transport channel at the SSE and cathode interface. As a result, SLBs exhibit excellent electrochemical performance at 25 °C. Further, the IL interlayer strategy combines with a high-voltage cathode to achieve higher energy density, and the batteries perform discharge specific capacities as high as 147 mA h g −1 . At the same time, the SLBs also exhibit more pronounced capacity degradation, which is attributed to the interfacial side reactions at high voltages. This work demonstrates the robust feasibility of the IL interlayer strategy and provides insights into the degradation mechanisms at the interface when matched with a high-voltage cathode. It offers valuable insights into the practical applications of SLBs and lays the foundation for subsequent research on high-voltage SLBs.

The increasing demand for supercapacitors with high energy and power density has attracted extensive attention in designing advanced carbon materials with high accessible surface area, hierarchical porosity , and 2D/3D morphology. Here, we report a new approach to tune the morphology and structure of the nanocarbons by using methyl cellulose as the precursor. Due to the varying effect of different activating agents, the interconnected sheet-like carbon with a high surface area of up to 2285 m 2 g −1 and a thickness down to ∼4 nm can be obtained. These important characteristics make the nanocarbons demonstrate a high capacitance of 144 F g −1 at 1 A g −1 and 20 °C, and an excellent capacitance retention ratio of 64% at 100 A g −1 in ionic liquid . Because of the high fraction of meso/macropores for nanocarbons, an outstanding capacitance of 116 F g −1 can be achieved at 0 °C, with a high capacitance retention ratio of 39% at 100 A g −1 . A high energy of 16–17 and 9–10 W h kg −1 can be maintained at 20 and 0 °C when the supercapacitor is charged in less than 1s. The excellent electrochemical response of nanocarbons suggests that the proposed preparation process is promising for developing advanced carbon electrodes.
