Graphical We for the first time use green deep eutectic solvents to recover solid electrolytes from all-solid-state lithium-ion batteries with high efficiency and high Li/La selectivity at mild temperature. Furthermore, we screen 70 kinds of anti-solvents for the precipitation of extracted metal from leachate and find that 12 kind of anti-solvents could successfully precipitate at room temperature with high efficiency. All-solid-state lithium-ion batteries (ASSLIBs) are attracting significant attention due to their high energy density, conductivity and safety. However, they are expected to generate substantial waste in the near future, leading to resource depletion and environmental pollution. Therefore, it is crucial to achieve green, mild and safe recovery of ASSLIBs. Here, we for the first time to use green deep eutectic solvents (DESs) to effectively recover solid-state electrolytes (SSEs) from ASSLIBs at mild temperature. Results show that Li leaching efficiency can reach up to 87.5 % with a superhigh Li/La selectivity of 1902 at a low temperature of 80 °C. Furthermore, 70 anti-solvents are screened to recycle the dissolved SSEs from leachate and 12 anti-solvents could precipitate SSEs from leachate at room temperature. This research opens new possibilities for recovering SSEs from ASSLIBs using the sustainable, cost-effective and safe solvents.

Graphical Natural low-melting mixture solvents could be used to achieve mild, safe and efficient recovery of all-solid-state electrolyte and cathode from all-solid-state sodium-ion batteries with high selectivity. Moreover, water is found to be the green and low-cost anti-solvent to precipitate the extracted metal from the leachate with low-energy consumption at room temperature. Spent all-solid-state sodium-ion batteries (ASIBs) containing toxic and precious metal would be produced significantly and lead to resource waste and environmental pollution as the wide application of ASIBs in the near future. Therefore, it is necessary to develop green strategy for recovery of ASIBs. Here, we propose a safe, mild and green strategy to recover toxic and precious metals from cathode/solid electrolyte of ASIBs by using natural low-melting mixture solvents (LoMMSs) with high selectivity and high leaching efficiency. Natural LoMMSs are abundant, natural available, cheap, non-flammable, biodegradable and biocompatible. Results show that natural LoMMSs could leach nearly 100 % Na and achieve superhigh Na/Zr selectivity of up to 58 from ASIBs at mild temperature, outperforming the recycling efficiency and selectivity of lithium-ion batteries cathode. More importantly, we find that water could be used as a green and low-cost anti-solvent to precipitate the extracted metal from the leachate with low-energy consumption at room temperature. This work provides a cost-effective, energy-saving, mild, green strategy for the recovery of cathode/solid electrolyte from spent ASIBs with high safety and high selectivity.

Traditional rigid polyurethane foam (RPUF) with flame retardancy might be easily damaged in some moist condition due to its hydrophobicity, which would lead to unsafety. Therefore, novel surfactants with both hydrophobic fluorinated group and flame-retardant phosphorus group were synthesized. With lower surface tension and more hydrogen bonds formed in polyurethane, the mixed surfactants, which were used in the preparation of RPUF, have not only obviously improved the size uniformity and integrity of cells but also enhanced its hydrophobicity, compressive strength and thermal insulating performance. Besides, effective ‘protection’ could be constructed on the surface of RPUF by prepared surfactants, when ammonium polyphosphate (APP) and expandable graphite (EG) were introduced to provide good flame retardancy. As a result, with just 2.8 wt% content of those functional surfactants, hydrophobic and flame-retardant RPUF with water contact angle of 126 °, limiting oxygen index of 25 %, compressive strength of 1.3 MPa and thermal conductivity of 27 mW/mK, were finally obtained, which is ahead of other flame-retardant RPUF reported before. It’s worth noting that, this hydrophobic and flame-retardant RPUF exhibits more stable and durable properties when soaking in HCl solution (2 mol/L), NaOH solution (2 mol/L), NaCl saturated solution and various solvents (THF and EtOH), or under strong fiction for 100 times and high and low temperature cycling test for 20 times. This would provide a novel and effective strategy to endow RPUF with enhanced and durable flame retardancy, hydrophobicity, compressive strength and thermal insulating performance even under extreme conditions.

Methyl sec-butyl ether (MSBE), a volatile organic compound, poses significant risks to both environmental safety and human health. Consequently, developing efficient sensors for the rapid and accurate detection of trace levels of MSBE is essential. In this study, we synthesized mesoporous CeO2 nanoparticles using carbon quantum dots as templates, resulting in the development of a highly sensitive cataluminescence sensor system. This sensor demonstrated an impressive linear detection range of 0.50–20 mg l−1 (R2 = 0.998) and a low detection limit of 0.08 mg l−1, coupled with a signal-to-noise ratio (S/N) of 3. We applied the mesoporous CeO2 nanoparticle sensor to measure MSBE levels in various environments, including a volatile medicine reagent freezer, laboratory gas, and a storage cabinet, which yielded concentrations of 2.07, 1.38, and 3.96 mg l−1, respectively. The sensor also exhibited excellent recovery rates, ranging from 91.1% to 110%, with relative standard deviations (RSD, n = 5) from 3.4% to 8.7%, indicating reliable performance. Additionally, gas chromatography-mass spectrometry was employed to elucidate the mechanism underlying the developed cataluminescence sensor. This study introduces a versatile approach for designing gas sensors for MSBE that not only exhibits high sensitivity and selectivity but also significantly enhances their potential applications in both industrial and environmental monitoring.

The high toxicity and bioaccumulation of heavy metal ion pollutants pose severe threats to the environment and public health. Tilted fiber Bragg grating-based surface plasmon resonance (TFBG-SPR) sensors have emerged as effective tools for heavy metal ion sensing owing to their portability and rapid response. These sensors typically feature a single plasmonic structure. And they are constrained by hardware restrictions and complex spectral analyses. Thus, these conventional designs render multicomponent detection and precise analysis challenging. To address these limitations, this study introduces a lightweight multichannel sensing platform based on a composite plasmonic TFBG structure. A two-dimensional metal–organic framework (2D MOF Cu-TCPP(Pt)) and silver nanoparticles (AgNPs) are integrated onto a gold (Au)-coated TFBG surface. This configuration enables strong coupling between the SPR and localized SPR (LSPR). Hence, the signal sensitivity is enhanced. The molecular sieve effect of the Cu-TCPP(Pt) improves the target analyte enrichment and suppresses the background interference, thereby ensuring a stable signal output. Additionally, a DNA aptamer conformational switching strategy ensures selective target analyte recognition. This platform integrates an AgNPs@Cu-TCPP(Pt)/Au/TFBG sensor, optical channel array, and real-time signal processing module and enables simultaneous detection of Pb 2+ , Cd 2+ , and Hg 2+ within 6 min, with detection limits of 0.007, 0.012, and 0.005 nM, respectively. The proposed sensor effectively mitigates background interference in complex matrices, demonstrating excellent linearity and recovery. Compared with conventional TFBG-based methods, this platform offers high sensitivity, short detection times, and enhanced robustness, and presents a novel solution for real-time multicomponent detection in complex matrices.

Microneedle (MN) patch has been used for collecting dermal interstitial fluid (ISF) containing biomarkers from patients with safety, pain-free and easy-to-use manner. However, long sampling time for biomarkers analysis still poses a significant challenge. Here, we describe a new sponge-forming MN patch consisting of polyvinyl formal (PVF) for rapidly extracting ISF from skin. Owing to the supreme water affinity of PVF, this MN patch can extract 1.6 mg ISF in 1 min without the assistance of extra devices, which remarkably facilitates timely analysis. The MN patch had preserved structural integrity in the swelling hydrated state without leaving residues in skin after usage, and the treated skin recovered within 8 h. More importantly, the extracted ISF can be efficiently recovered from the MN patch by simple centrifugation for the subsequent offline analysis of biomarkers such as glucose and cholesterol. Our results reveal that the new sponge-forming MN patch holds considerable promise for minimally invasive sampling ISF for biomarkers detection in real-life situations.

Oil spills have caused serious environmental problems, making oil absorbing materials highly important. Creating polymeric aerogels with compressive resilience, superhydrophobicity, high absorption capacity, and excellent regeneration capability remains challenging. In this study, polyacrylonitrile (PAN) nanofibers prepared by electrospinning were used as the aerogel skeleton, with carbon nanofiber (CNF) serving as flame retardants and conductive agents, and benzoxazine (BOZ) as a crosslinking agent. The composite nanofiber aerogels (PAN/PBOZ/CNF-x) were prepared through freeze-drying, followed by thermal curing of ring-opening of oxazine. The low-density aerogel (0.0113g/cm 3 ) exhibited remarkable properties, including over 96% compressive recovery after 30 cycles at 60% strain, superhydrophobicity (WCA = 150.6°), and low thermal conductivity (0.0346W/m·K at 25°C). Furthermore, they demonstrated high absorption capacities between 51.4 and 104.8 g/g for various organic solvents and realized rapid separation of oil-in-water emulsion, such as dichloromethane, with a maximum separation flux of 3022.59 L m −2 h −1 . Additionally, the aerogels showed excellent thermal stability (with a char yield of 83.6 % at 800°C for PAN/PBOZ/CNF-0.1 aerogel) and outstanding flame retardancy, endowing the aerogels with combustion regeneration capability, and providing a fast (∼1s) and durable (∼400s) hazard alarm response after fire removal, retaining 81.8% of their initial absorption capacity after ten combustion-absorption cycles. The multifunctionality of PAN/PBOZ/CNF-x aerogels offers a new strategy for designing advanced multifunctional aerogels.

Hydrophilic coatings are widely used in marine antifouling. Nevertheless, there are additional requirements for the robustness of marine antifouling coatings, including the ability to withstand scratches and damage. Therefore, the demand for self-healing properties and robust mechanical strength is high, presenting significant challenges. Herein, inspired by the elastic surface and exceptional water absorption capabilities of dolphins, a reversible interlocking polymer network with multiple hydrogen bonds was successfully developed. This innovation harnesses the properties of poly(urethane-urea) and ureido pyrimidinone, thereby enhancing both mechanical properties and antifouling performance. Furthermore, the modified 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide was incorporated into the system as a functional filler and to serve as crosslinking points, creating a multifunctional coating. Owing to the hierarchical hydrogen bonds (the hydrogen-bonded carbonyl groups in SPPU-01 reach as high as 56.80 %), SPPU-01 exhibits exceptional strength of 17.35 MPa (1132.17 %), remarkable toughness of 89.33 MJ/m 3 , and superior tear strength of 74.97 KN/m. Upon incorporating additional components, the composite crosslinking network enhances hydrophilicity (∼29.15°), thereby forming a hydration layer that effectively prevents fouling. The SPPU-02 reveals outstanding resistance to marine bacteria, effective anti-diatom adhesion, robust anti-mussel attachment, and strong anti-pseudo-barnacle properties, achieving 96.5 %, 94.5 %, 96.04 %, and 1.31 MPa, respectively. Furthermore, this strategy, which mimics dolphin functions, is well-suited for various marine materials with different requirements. It exhibits deicing (21.22 kPa), drag reduction, and high-temperature resistance properties (69.1 %), opening new avenues for the development of antifouling coatings with both strong and superior comprehensive performance.

Oil spill pollution poses a severe environmental threat, necessitating the development of efficient and sustainable remediation strategies. In this study, we designed and synthesized a series of pH-responsive phase-selective organogelators (pRPSOGs) based on d-gluconic acetal derivatives with long-chain amine groups to selectively solidify oil in oil/water mixtures, facilitating its rapid removal and recovery. The gelation behavior, phase-selective capability, and pH-switchable properties of the synthesized pRPSOGs were systematically investigated by using inversion tests, rheological analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and small-angle X-ray scattering. Molecular simulations were further conducted to elucidate the self-assembly mechanism of the gelators. The optimized gelator, A12, exhibited excellent thermal stability and mechanical strength, ensuring structural integrity during oil spill recovery. Importantly, the pH-responsive property of A12 allowed for reversible solubility modulation, enabling efficient separation and recovery of both the gelator and oil phase without the need for energy-intensive distillation. This innovative strategy provided a reusable, energy-efficient, and environmentally friendly approach for oil spill treatment, offering promising applications for large-scale environmental remediation.

In recent years, heavy oil-solid separation has attracted quantities of attention, and ionic liquids (ILs) enhanced solvent extraction has been widely studied. However, the detailed mechanism of ILs effect onto the heavy oil recovery was unclear, especially the interaction role between ILs and heavy oil SARA. In order to solve these problems, this paper used the experiment and molecular dynamics simulation methods to explore the four ILs ([Bmmim][PF 6 ], [C 12 mim][Ac], [C 12 mim][BF 4 ], and [Emim][Ac]) effect on enhancing the solvent extraction for oil sands. The experimental results showed that the ILs could enhance the solvent extraction process, improve heavy oil recovery, reduce bitumen viscosity, decrease oil-sand interaction force, alter the sand particles wettability. The extraction efficiency of [Bmmim][PF 6 ] + toluene reached 93.9 %. Additionally, molecular dynamics (MD) simulations were conducted to analyze the interaction mechanisms between heavy oil SARA (saturates, aromatics, resins, asphaltenes) and solvents and ILs. The simulations results indicated that the saturates, aromatics, resins and asphaltenes have different interaction role with the different ILs under varieties of solvents, and the interaction role strength was related to the functional groups and heteroatom. In the end, the detailed mechanism of ILs enhancing solvent extraction for oil sands was put forward.

One hundred low-melting mixture solvents (LoMMSs) are utilized to systematically investigate the impact of acid–base regulation on the leaching efficiency of all-solid-state electrolytes. Results show that the acidity of LoMMSs is positively correlated with the Li leaching efficiency in the all-solid-state electrolytes aluminum-doped lithium lanthanum zirconium oxide and lithium lanthanum zirconium tantalum oxide (LLZTO); however, there is a two-piece linear fitting tendency between the acidity of LoMMSs and La leaching efficiency in the LLZTO. Furthermore, the impact of factors such as the temperature, time, and liquid-to-solid ratio on the dissolution of all-solid-state electrolytes by LoMMSs is also investigated. The leaching efficiencies of LoMMSs for recovering Li and Zr from the all-solid-state electrolytes are 99.24 and 83.74%, respectively. When LoMMSs and the all-solid-state electrolytes are scaled up 100 times to simulate industrial applications, the leaching efficiency of Li decreases only slightly (from 94.81 to 94.70%).

The increasing demand for thermally conductive adhesives (TCAs) in high-performance electronic devices necessitates materials with both flame retardancy and thermal conductivity. Conventional TCAs often struggle with balancing these properties, particularly due to poor interfacial compatibility between fillers and the resin matrix. To address this challenge, this work introduces a novel approach by functionalizing boron nitride nanosheets (BNNSs), with 2,6-bis(urazole-1-yl) pyridine (UPy). This modification enhances both thermal conductivity and flame retardancy in EP-based composites. Thermogravimetric analysis revealed that the initial decomposition temperature ( T 5% ) of the 20-UPy-BNNSs/EP composite increased to 344.8 °C, a 74.0 °C rise from pure EP. Microcalorimetry tests showed a 42.7 % reduction in peak heat release rateand a 17.7 % reduction in total heat release compared to pure EP. Vertical burning tests demonstrated that the 20-UPy-BNNSs/EP composite significantly delayed ignition and suppressed molten droplet formation. In practical electronic device testing, the 20-UPy-BNNSs/EP composite reduced the surface temperature of LED drivers by 53.3 °C compared to the control, highlighting its effective thermal management. These results confirm that UPy modification improves the interfacial interaction between BNNSs and the EP matrix, leading to increased thermal conductivity and flame retardancy. This work proposes a promising strategy for developing high-performance TCAs tailored to next-generation electronics.
