Infection and oxidative stress seriously hinder the healing of diabetic wounds, resulting in various serious health and clinical problems. Herein, a sustainable biological hydrogen (H2)-producing hyaluronic acid–based hydrogel patch (HAP-Chl) was constructed by loading an imidazolium-based poly(ionic liquid) (PIL) flocculated live Chlorella as a diabetic wound dressing. The PIL can flocculate Chlorella through electrostatic interactions between PIL and Chlorella to form Chlorella agglomerates, endowing the Chlorella in the central agglomerates with the ability to continuously produce H2 for 24 h under mild conditions. Combining the membrane disruption-related bactericidal mechanism of PIL and the antioxidant properties of the produced H2, HAP-Chl was determined to be antibacterial and antioxidant. In addition to exhibiting biocompatible and nontoxic activities, subsequent Staphylococcus aureus-infected chronic wound studies revealed that HAP-Chl is capable of promoting the healing of chronic wounds by effectively killing bacteria, reducing extensive ROS, relieving inflammation, and promoting the deposition of mature collagen and angiogenesis. This study provides a new strategy for constructing an in situ sustainable H2-producing hydrogel, enabling the formation of novel antibacterial and antioxidant material platforms with potential for wound dressing applications.

Thermoelectric technologies (TEs) offer immense potential for waste heat recovery and energy storage. However, the practical application of current TEs has been severely hampered by potential performance degradation in extreme environments, particularly at high temperatures, due to electrolyte flammability or poor carrier mobility. The development of high-temperature, high-performance TEs is crucial for broadening their operational range and enabling diverse applications. Here, practical high-temperature high-voltage thermal charging cells (HHTCCs) are reported, facilitated by a heat-resistant trifluoromethanesulfonate-based Ca–Li dual-cationic ionic liquid electrolyte containing functionalized AmimCl solvent, together with a thermotolerant composite membrane, PEN(polyphenylene-ether-nitrile)@ZrBDC-F-4%. The dual-cation mechanism enables high thermal voltage through cooperative energy storage, while the functionalized AmimCl accelerates the mobility of Ca 2+ and Li + ions by weakening the surrounding shielding effect. Additionally, the anionophilic ZrBDC-F-4% nanoparticles in the composite membrane enhance carrier migration. As a result, the HHTCCs exhibit an impressive thermal voltage of 1.138 V, a remarkable thermopower of 15.3 mV K −1 , and an outstanding Carnot-relative efficiency of 9.56% over an unprecedented temperature range from 328.15 to 393.15 K, demonstrating the excellent safety and feasibility of HHTCCs. This work expands the service-temperature range of i-TEs, holding significant promise for high-temperature, high-performance waste heat harvesting.

Usually, traditional poly (ionic liquid)s are prepared to nanoparticles with high surface areas for achieving a quasi-homogeneous reaction system. In this work, a novel poly (ionic liquid) P(VB-VS)HSO 4 , synthesized by simply using ionic liquids immobilized on the 1-vinylimidazole-based crosslinked copolymer microsphere, was used as heterogeneous catalyst for transesterification of a novel non-edible feedstock soapberry oil to biodiesel. The structure, thermal stability and wetting property characteristics of the crosslinked copolymer microsphere particles and poly (ionic liquid) microspheres were investigated. The results indicated that ionic liquids were successfully functionalized on crosslinked copolymer microsphere, and P(VB-VS)HSO 4 possessed high surface areas (100.1 m 2 /g), abundant meso -macropores (with diameter of ∼18.9 nm), good mechanical strength (81 N) and superior thermal stability. Benefiting from the unique structure features, these poly (ionic liquid) microspheres manifested excellent catalytic performance for transesterification of soapberry oil with methanol. A maximum fatty acid methyl esters (FAMEs) yield of 95.2% could be obtained under the response surface methodology (RSM) optimized conditions of 8.0 h reaction time, 29.1 methanol to oil molar ratio, and 8.7 wt% catalyst amount. Impressively, it was also efficient for the esterification of oleic acid, giving methyl oleate yield of 97.5%. Catalytic tests exhibited that P(VB-VS)HSO 4 presented high catalytic activity and good reusability in comparison with traditional acid catalysts. The main physicochemical of the obtained soapberry biodiesel met the biodiesel standard ASTM D6751 . Therefore, this work provides a cheap and facile route to the synthesis of size-controlled poly (ionic liquid) microspheres (the diameter of the catalyst was about 500 μm) for catalyzing the production of clean biofuels.

Controllable synthesis of self-associating lauroyl-grafted chitosan with high molecular weight was realized in ionic liquid reacting media. The obtained lauroyl chitosan with different grafting degrees was characterized by FT-IR and 1H-NMR spectra. The chitosan derivatives were able to self-assemble into spherical polymeric micelles in water. The onset of micellization or critical micelle concentration (CMC) was estimated by fluorescence spectroscopy. The hydrodynamic diameters of various lauroyl chitosan micelles, determined by dynamic light scattering, were in the range of 122–295 nm. The morphology of the micelles was observed by scanning electron microscopy. The self-assembly behavior and the size of the assembled micelles of lauroyl chitosan were affected by the grafting degree of lauroyl groups. Generally, higher grafting degree resulted in lower CMC and smaller micelle size. These lauroyl chitosan nano-micelles may have potential applications in biological and medical fields.

Compared with other types of sensors, capacitive flexible pressure sensors (CFPS), with low sensitivity, are more susceptible to environmental changes. It is still a considerable challenge to achieve high sensitivity, excellent mechanical properties and long-time structural stability simultaneously. Targeting the aforementioned issues, herein, Ti3C2 (MXene) with high dielectric constant was firstly chemically modified with a poly(ionic liquid) (PIL) via surface-initiated ATRP, and then combined with a porous polyurethane foam (PUF) 3D network structure via a one-step blending foaming method. Thanks to the organic-inorganic hybrid network based on the PU/MXene porous structures and the uniformly distributed micro-capacitor structure provided by MXene@PIL, the mechanical properties, structural stability, flame retardancy and dielectric properties of the composite foam were all significantly enhanced. When the content of MXene@PIL was 10%, the sensitivity of CFPS based on this dielectric were 17.1, 5.2, and 2.5/KPa in the pressure ranges of 0-1 KPa, 1-12 KPa and 12-100 KPa, respectively. In addition, the sensor showed the response and recovery times of 88 and 82 ms under a low pressure of 355 Pa. The light, flexible sensor prepared in this work is expected to be used in wearable devices to monitor physiological signals, and it should also be a good candidate for the next generation of man-machine interface characterization devices.

An ionic liquid (IL)-based monolithic poly(ionic liquid glycidylmethacrylate- co -ethylene glycol dimethacrylate) column was prepared via in situ free-radical polymerization with 1-vinyl-3-butylimidazolium chlorine as one of the comonomers. The obtained monolithic column was used as the sorbent of solid-phase extraction (SPE) and coupled with high-performance liquid chromatography for the simultaneous determination of the macrolide antibiotics roxithromycin (ROX) and acetylspiramycin (ACE) in processed pure milk. The monolithic column was characterized by Fourier transform infrared spectrometry, scanning electron microscopy, nitrogen absorption–desorption, mercury intrusion porosimetry, and thermogravimetric analysis. The results reveal that the monolithic column exhibited a high selectivity and good permeability to the macrolide antibiotics in milk. The optimized method offered excellent linearity with a linear regression coefficient greater than 0.998. The precisions for interday and intraday were both less than 7.7%. The accuracies expressed by the recoveries for ROX and ACE were in the ranges 92.5–103.8 and 93.0–107.6%, respectively. Compared to the previous methods, this method had a low limit of detection and a good accuracy. As a result, the polymer IL based monolithic column could feasibly be used as a high-selectivity online SPE sorbent for determining trace macrolide antibiotics in milk. © 2016 Wiley Periodicals, Inc.

Heteroatom-doped hierarchical porous carbon materials derived from the potential precursors and prepared by a facile, effective, and low-pollution strategy have recently been particularly concerned in different research fields. In this study, the interconnected nitrogen/sulfur-codoped hierarchically porous carbon materials have been successfully obtained via one-step carbonization of the self-assembly of [Phne][HSO4] (a protic ionic liquid originated from dilute sulfuric acid and phenothiazine by a straightforward acid–base neutralization) and the double soft-template of OP-10 and F-127. During carbonization process, OP-10 as macroporous template and F-127 as mesoporous template were removed, while [Phne][HSO4] not only could be used as carbon, nitrogen, and sulfur source, but also as a pore forming agent to create micropores. The acquired carbon materials for supercapacitor not only hold a large specific capacitance of 302 F g–1 even at 1.0 A g–1, but also fine rate property with 169 F g–1 at 10 A g–1 and excellent capacitance retention of nearly 100% over 5000 circulations in 6 M KOH electrolyte. Furthermore, carbon materials also present eximious rate performance with 70% in 1 M Na2SO4 electrolyte.

An electrochemical method has been successfully demonstrated for sensitive determination of Metronidazole (MTZ) with graphene (Gr)-room temperature ionic liquid (IL) of 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF 6 ) composite modified glassy carbon electrode (GCE). The cyclic voltammetric results indicate that Gr-IL/GCE can remarkably enhance electrocatalytic activity towards the reduction of MTZ in neutral solutions. MTZ produce a cathodic peak at about −0.69 V at this electrode. The electrochemical parameters of MTZ in the composite film were carefully calculated with the results of the charge transfer coefficient ( α ) as 0.625 and the number of electron transferred ( n ) as 4. The electrocatalytic behavior was further exploited as a sensitive detection scheme for the MTZ determination by differential-pulse voltammetry (DPV). Under optimized conditions, the concentration range and detection limit were 1.0 × 10 −7 –2.5 × 10 −5 mol L −1 and 4.7 × 10 −8 mol L −1 ( S / N = 3), respectively for MTZ. The method was successfully applied assay of the drug in the pharmaceutical dosage forms .

GR and AuNPs were directly electroreduced on the surface of CILE to get the modified electrode , which exhibited excellent electrochemical performances due to the specific characteristics including higher conductivity and larger surface area . The modified electrode showed excellent electrocatalytic ability to the oxidation of FA with an irreversible oxidation peak appeared at + 1.05 V (vs. SCE) in pH 5.5 phosphate buffer solution . Electrochemical behaviors of FA on the modified electrode were carefully investigated with the electrochemical parameters calculated. Under the optimal conditions and by using differential pulse voltammetry , the oxidation peak currents were linear to FA concentration in the range from 0.01 μmol L − 1 to 50.0 μmol L − 1 with the detection limit as 2.7 nmol L − 1 (3σ).

Highly efficient HMF synthesis was realized in μPBRs over ACB18-Si-ILs. • HMF (90.8%) or LA (65.2%) was selectively produced in μPBRs within 252 s. • ACB 18 -Si-ILs stably catalyzed fructose conversion to HMF in μPBRs for 1440 min. • Product yields in μPBRs were predicted by an intrinsic kinetic model. • LHHW kinetic analysis identified the surface reaction as the rate-determining step. In this work, acidic ionic liquids (ILs) were immobilized on activated carbon beads (ACB) with a particle size of 0.3 mm (ACB 18 -Si-ILs), and combined with micropacked bed reactors (μPBRs) to achieve continuous and long-term conversion of fructose to 5-hydroxymethylfurfural (HMF). After pretreatment, the specific surface area of ACB reached 1249.4 m 2 /g, and the ionic liquid was chemically bonded to the support, exhibiting good stability. Selective production of HMF and levulinic acid (LA) was achieved through reaction optimization and solvent regulation, achieving a yield of 90.8% HMF or 65.2% LA within 252 s in μPBRs. The space-time yield of HMF and LA were both increased by an order of magnitude compared to traditional reactors, and the HMF yield maintained over 85% after 1440 min continuous operation. A heterogeneous intrinsic kinetic model was established for predicting product yield in μPBRs, with the error controlled within ±15%. Under the intrinsically kinetic controlled regime, the Langmuir-Hinshelwood-Hougen-Watson model was constructed, identifying the catalyst surface reaction as the rate-limiting step. The adsorption constants of fructose and HMF were obtained and the catalyst surface reaction rate was predicted with an error less than ±10%.

A new strategy for enhancing the
hydrazine structure based on the
inductive effect and conjugation effect of strong electron-withdrawing
groups has been designed to effectively absorb CO 2 with
hydrazide-based ionic liquids (ILs). All three ILs aqueous solutions
(diethylenetriamine oxalyl dihydrazide [DETAH] 2 [ODH], diethylenetriamine
propanedioyl dihydrazide [DETAH] 2 [PDH], and diethylenetriamine
succinic dihydrazide [DETAH] 2 [SDH]) exhibit good absorption
performance. Through a combination of absorption–desorption
experiments, FT-IR and NMR characterizations, and density functional
theory (DFT) calculations, the results indicate that the unique structure
of anions enables physical adsorption to occur again after chemically
absorbing CO 2 . The special absorption process is responsible
for the unusual regeneration properties. Hopefully, the results of
this work are helpful in providing a new method for designing highly
efficient gas absorbents.

Energy storage is crucial for integrating renewable energy in buildings. Cement-based supercapacitors (CSCs) offer a viable platform for integrating structural integrity with electrochemical energy storage, yet their practical application is severely hindered by the narrow voltage window, interfacial limitations, and thermal instability of aqueous electrolytes. Here, we develop a CSC by coupling dual-continuous ionic pathways in a polyacrylamide-modified cement matrix with ionic-liquid interfacial regulation. Continuous pore/polymer ion-transport networks were constructed in the rigid cementitious matrix, followed by post-curing vacuum impregnation of a non-aqueous ionic liquid to regulate the electrolyte/porous electrode interface. This coupled design improves ion-transport continuity and enhances ion accessibility, driving the electrode utilization efficiency up to 84.7% at 1 mA cm -2 . Enabled by the widened 2.0 V voltage window and high electrode utilization, the device achieves an areal capacitance of 1271.7 mF cm -2 , and an areal energy density of 562.4 μWh cm -2 . From 20 to 80 °C working temperature, the energy and power densities further increase by 52.7% and 13.0%, respectively, with negligible electrolyte loss. These results demonstrate that coupling ionic pathway design with interfacial regulation is an effective strategy for improving active-site accessibility, electrode utilization, and thermal robustness in rigid porous CSCs.
