Lignocellulosic biomass has emerged as a promising renewable energy source in industrial applications; however, its robust structure requires effective pretreatment to facilitate its conversion into valuable end-products. In this work, we systematically evaluated the efficacy of polyols in enhancing acidic deep eutectic solvents (DESs) during the pretreatment and enzymatic hydrolysis of wheat straw. Our findings demonstrated that the integration of polyols, with the exception of xylitol, into choline chloride/oxalic acid (ChCl/OA) improved DES pretreatment fractionation and subsequent enzymatic digestibility, with ethylene glycol (EG) demonstrating the highest efficacy. This enhancement was confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. Moreover, nuclear magnetic resonance (NMR) analysis was employed to elucidate the underlying mechanism by which the incorporation of polyols contributed to preserving the β-O-4 substructure of lignin, diminishing lignin condensation, and thereby improving enzymatic saccharification. Further optimization studies identified the optimal pretreatment conditions to be a ChCl/OA/EG molar ratio of 1:1:2, at 110 °C for 2 h. Collectively, our study not only paves the way for efficient wheat straw enzymatic hydrolysis but also offers a framework for the design and selection of DESs in the pretreatment of lignocellulosic biomass.

BACKGROUND The recycling of spent lithium-ion batteries (LIBs) is crucial for resource conservation and environmental sustainability, particularly due to the valuable metals they contain, such as cobalt and lithium. This study focuses on developing an ion-exchange method for cobalt recovery from waste LIB solutions, using a mesoporous silica derivative of carbamoyl sulfamic acid (PST-SA) as the adsorbent. RESULTS The batch method for adsorption experiments identified the most effective conditions: a pH of 8, 0.08 g PST-SA, and a shaking time of 60 min, at room temperature. These experiments demonstrated a remarkable cobalt uptake capacity of 270.70 mg g −1 , highlighting PST-SA's exceptional adsorption capabilities. Additionally, thermodynamic studies revealed the adsorption process to be both endothermic and spontaneous, enhancing our understanding of its chemically reactive mechanisms. CONCLUSIONS The practical application of PST-SA, particularly when processing spent LIBs, showcases its real-world utility. The efficient separation of cobaltous oxalate and lithium phosphate into pure forms emphasizes PST-SA's potential in recycling and resource recovery. Given its cost-effectiveness and strong adsorption capacity, PST-SA stands out as an excellent solution for the removal of Co(II) from discarded LIBs, promoting sustainable material recovery practices. © 2024 Society of Chemical Industry (SCI).

Ionic liquids (ILs) have emerged as new persistent pollutants in aquatic environments due to their notable ecotoxicity. Herein, In 2 Se 3 @Ag 3 PO 4 S-scheme piezo-photocatalyst with interfacial In-O and Se-P covalent bonds is prepared for efficient degradation of 1-butyl-2,3-dimethylimidazole bromide ([BMMIm]Br). The experimental results demonstrate that 98.3 % of [BMMIm]Br is degraded under piezo-photocatalysis. Notably, [BMMIm]Br functions as a hole sacrificial agent, leading to a simultaneous H 2 production rate of 582.7 μmol g −1 h −1 and a co-removal efficiency of 97.2 % for radioactive heavy metal ions of U(VI), achieving the "three birds with one stone" effect. Density functional theory (DFT) calculations indicate that the S-scheme structure, combined with the In-O and Se-P covalent bonds and the piezoelectric effect, effectively promotes the separation of electron/hole pairs while inhibiting carrier recombination dynamics, thereby enhancing piezo-photocatalytic performance. Moreover, systemic toxicity evaluations, including assessments of calculated toxicity, zebrafish growth, and bean sprout development, were conducted to verify the reduced toxicity of the degraded intermediates, highlighting the potential practical applications of this approach.

Pectin derived from the fruit of Clausena lansium (Lour.) Skeels, commonly known as Wampee, possesses diverse bioactivities and holds significant potential for applications in food products. To broaden Wampee's application range, deep eutectic solvent (DES) was optimized for pectin extraction using response surface methodology. The fundamental and functional properties of DES-extracted pectin (D-CP) were compared to water-extracted pectin (W-CP). Extracted under the optimal extraction conditions (oxalic acid:choline chloride ratio was 1:1, reagent content was 10.2% (w/v), extraction time was 154 min, temperature was 82.5°C, and liquid: solid was 10.0 mL/g), D-CP was identified as Rhamnogalacturonan-dominated pectin. D-CP's molecular weight (129 kDa) and degree of esterification (61.05%) were lower than those of W-CP. However, D-CP exhibited a superior yield (18.09%) and enhanced functional properties, including higher purity, improved emulsifying stability and activity, better foaming capacity, and stronger foam stability. Additionally, D-CP demonstrated excellent solubility alongside notable antioxidant activities. Overall, these advanced properties highlight D-CP's promising potential for applications in the food and pharmaceutical industries, with DES proving to be an effective solvent for efficient extraction of bioactive pectin from Wampee.

Aqueous zinc-ion batteries (AZIBs) offer promising safety and affordability, but suffer from dendritic Zn growth and parasitic side reactions at the electrode-electrolyte interface. Herein, we construct a dual-region interfacial modulation framework by molecularly reconfiguring the Helmholtz double layer via trace methyl methacrylate (MMA). Exploiting its amphiphilic and functionally asymmetric architecture, MMA enables a coordinated interfacial reconstruction that disrupts Zn 2+ solvation in the outer Helmholtz plane, builds a chemisorbed coordination layer in the inner plane, and modulates local interfacial chemistry with spatial precision. This dual-region regulation collectively suppresses water reactivity, facilitates Zn 2+ desolvation, and drives crystallographically preferred deposition along the (101) plane, promoting lateral growth and mitigating dendrite formation. As a result, symmetric Zn||Zn cells exhibit over 4200 hours of stable cycling at 1 mA cm -2 and maintain 1100 hours of operation at 2 mA cm -2 , even at 0 °C. Zn||Ti half-cells achieve a Coulombic efficiency of 99.83%, while Zn||NH 4 V 4 O 10 full cells deliver 93.92% capacity retention after 400 cycles at 2 A g -1 , and preserve 85.3% after 300 cycles at 0 °C. This work demonstrates a scalable, mechanism-driven electrolyte design paradigm for dendrite-free and high-performance aqueous Zn metal batteries.

High-safety and low-cost Na 4 Fe 1.5 Mn 1.5 (PO 4 ) 2 (P 2 O 7 ) (NFMPP) is a highly promising cathode for Na-ion batteries (SIBs), offering a higher energy density than typical NFPP. However, its performance is hindered by Na/Mn anti-site defects and Jahn-Teller (J-T) distortion, resulting in voltage hysteresis and sluggish Na-ion diffusion kinetics. Herein, we demonstrate a high-rate and long-life NFMPP cathode by synergistically optimizing the initial molar ratio of Na-ion to transition metal (Na/TM) and vanadium (V) doping. The Na/Mn anti-site defects have been greatly alleviated from 5.9 % to 2.2 %, effectively suppressing the voltage hysteresis of Mn 2+ /Mn 3+ redox plateau. Meantime, the electron-rich V doping with strong V-O bonds (541 kJ/mol) exhibits strong interaction with Mn, significantly reducing the effect of J-T distortion on Na-ion diffusion. As a consequence, the optimized NFMPP cathode delivers a superior initial charge capacity of 115.1 mAh/g at 0.1C and achieves a high reversible energy density of 334 Wh/kg, surpassing many reported phosphate-based cathodes. It also exhibits exceptional cycling stability, retaining 94.1 % of its capacity after 500 cycles, making it a highly competitive candidate for next-generation SIBs.

This work develops a novel phosphate-functionalized extraction resin (HEHEHP + Cyanex272)/SiO2-P via the vacuum impregnation method for efficient separation of light rare earth element impurities from lanthanum (La3+) in nitric medium through synergistic extraction. Batch experiments have demonstrated superior adsorption selectivity toward impurity ions over La3+in a pH 4 nitric acid solution. Column studies confirmed exceptional performance under ambient conditions, achieving a lanthanum treatment capacity of 120.6 mg/g and over 98% impurity removal, which surpasses most reported values. Notably, this purification process enables direct production of purified La3+solutions through a single-column system without desorption, significantly enhancing efficiency and reducing costs. Mechanistic insights revealed combined ion exchange and coordination interactions between metal ions and P-OH/P=O groups, corroborated by advanced characterization and density functional theory calculations. These findings indicate a higher binding affinity of light rare earth compared with La3+. This strategy provides a scalable approach for ultra-high-purity lanthanum compound production in advanced optical and electronic applications.

Developing structural energy storage materials (SESM) to address the range anxiety of aerial and aerospace vehicles is crucial. These materials must have a homogeneous, open structure, high specific energy, environmental adaptability, and ease of machining. Traditional capacitor-based or lithium-ion battery embedded structures fail to meet these demands simultaneously. In this study, the high energy density and environmental adaptability of zinc-ion batteries are integrated with the superior mechanical performance and ionic conductivity of a bi-continuous phase electrolyte, resulting in the creation of an open-structured composite. Through microphase separation simulation and optimization of mass transfer channels, the best formulation (MEP30) is achieved, featuring high mechanical strength (108 MPa Young’s modulus) and ionic conductivity (0.56 mS cm –1 ). An NH 4 V 4 O 10 @Carbon fiber (CF)||electrolyte||Zn@CF structure is developed, capable of multi-layer expansion. This design improves interlayer stress distribution and reduces weight, enhancing mechanical properties (408 MPa Young’s modulus) and system energy density (20 wh kg –1 ). The material can be machined into various shapes and remains functional after destructive processes like perforation and cutting. Under extreme conditions (low temperature, water immersion, low pressure) simulating aerial and aerospace environments, the multilayer material retains its energy density, offering a promising approach for SESM development.

Novel wet-phase modified expandable graphite (WMEG) particles were developed for in-depth profile control in carbonate reservoirs. The harsh environment of carbonate reservoirs (≥ 130 °C, ≥ 22 × 10 4 mg/L) brings significant challenges for existing profile control agents. WMEG particles were developed to address this problem. WMEG particles were synthesized via intercalation with ultrasound irradiation and chemical oxidation. The critical expansion temperature of WMEG particles is 130 °C, and these particles can effectively expand 3–8 times under high temperature and high salinity water. The core flow experiments show that WMEG particles exhibit a good plugging capacity, profile control capacity, and a better-enhanced oil recovery (EOR) capacity in deep carbonate reservoirs. WMEG particles can be expanded in the formation and form larger particles that bridge the upper and lower end faces of the fracture. Then the high-permeability zones are effectively plugged, and the heterogeneity is improved, resulting in an obvious increase in oil recovery. This research provides a novel insight into future applications of profile control agents for in-depth profile control treatment in carbonate reservoirs.

A facile, fast and visible sensing platform for ascorbic acid (AA) detection has been developed based on self-assembled hydrangea-like europium metal-organic framework (HL-EuMOF). HL-EuMOF was synthesized through a simple one-step mixing process with Eu 3+ and 1, 10-phenanthroline-2, 9-dicarboxylic acid at room temperature , which exhibited excellent properties including strong red fluorescence, long decay lifetime (548.623 μs) and good luminescent stability. Based on the specific redox reaction between Fe 3+ and AA, the HL-EuMOF@Fe 3+ was fabricated with “turn-off” response for AA, where the resulting Fe 2+ displayed effective fluorescence quenching ability toward HL-EuMOF. The sensor demonstrated low detection limit (31.94 nM), rapid response time (30 s) and high selectivity. Integration of smartphone-assisted RGB analysis with HL-EuMOF@Fe 3+ permitted convenient and visible quantitative determination of AA level. This approach also presented good detection performances in complex human serum and beverage samples, which could provide a valuable tool for AA detection in biomedical research and food industry.

This study investigates the application of a self-designed continuous high pressure processing (CHP) system for the pasteurization of delavayi juice, emphasizing both numerical simulations of the equipment system and experimental quality evaluations of the juice. The treatment at 400 MPa indicated through numerical simulations that the juice achieved a peak velocity of 719 m/s, resulting in higher shear rates and improved mixing, which enhanced processing efficiency. The experimental analysis demonstrated that CHP significantly reduced the particle size of the juice to 0.01–1 μm ( p < 0.05), improving its cloud stability. Compared to thermal pasteurization processing at 80 °C for 20 min, CHP better preserved the juice's original color, closely resembling that of untreated juice. Furthermore, CHP outperformed thermal methods in maintaining the flavor profile, particularly at 400 MPa, and proved more effective in preserving levels of vitamin C (30.45 mg/mL), total phenolics (27.97 mg rutin/mL), flavonoids (95.76 mg GAE/mL), and antioxidant activities ( p > 0.05 ). This study highlights the potential of CHP as a high-throughput, efficient, and non-thermal pasteurization method for fruit juice, providing a viable alternative to traditional thermal treatments.

The tailorable meso-macroporous structure of hierarchical porous carbon (HPC) is an essential key to improve ion diffusion dynamics and microporous accessibility for capacitive material. However, few studies focus on the capacitive mechanism of meso-macroporous proportion of HPC. Herein, a regionally selective dissolution and pyrolysis strategies are deployed to tailor the proportion of meso-macropores in facial mask-derived HPC through adjusting the oxalic acid concentration in hydrothermal process in this contribution. The obtained HPC show increasing meso-macroporous volumes of 0.04, 0.12, and 0.40 cm 3 g −1 , corresponding to the oxalic acid concentrations of 0.2, 0.5, and 1.0 g/50 ml, respectively, while the microporous structures remain similar. Electrochemical results show that with increasing proportion of meso-macropores, the specific capacitances of HPC decrease from 386.9 to 276.5 and 220.3 F g −1 at current density of 1 A g −1 , and decrease from 216.7 to 181.1, and 133.1 F g −1 at 50 A g −1 . CV fitting results indicate that a small number of meso-macropores can enhance the surface-controlled capacitive contribution, improving the accessibility of micropores and faradaic pseudocapacitive reactions. The optimized HPC-based supercapacitor delivers a high energy density of 11.5 Wh kg −1 at a power density of 125 W kg −1 in KOH electrolyte and a maximum energy density of 49.4 Wh kg −1 at 225 W kg −1 in Na 2 SO 4 electrolyte with long cycle stability, suggesting that the rational engineering of meso-macroporous proportion in HPC uncover news insights into developing high performance supercapacitor.
