Zero-valent iron (ZVI) technology is regarded as one of the most efficient approaches for remediating groundwater contaminated with chlorinated hydrocarbons (CHCs). Despite its highly reactive nature, the corrosion of ZVI in aqueous solution readily results in surface passivation, which diminishes its reactivity. ZVI doped with heteroatoms such as carbon (C), nitrogen (N), and sulfur (S) has displayed excellent performance in trichloroethylene (TCE) degradation. Nevertheless, the effects of these heteroatoms on ZVI materials, along with their various degradation mechanisms, remains ambiguous. In this study, C-mZVI bm , N-mZVI bm , and S-mZVI bm were prepared, respectively, via a mechanochemical method and utilized for TCE degradation. The dechlorination reaction facilitated by each material was thoroughly investigated both theoretically and experimentally, focusing on TCE adsorption affinity, the dechlorination process, hydrogen evolution reaction (HER), electron efficiency, and lifetime. Among the three materials, S-mZVI bm exhibited 100% TCE removal in less than 24 h., as well as improved electron efficiency and lifetime, primarily attributed to its high TCE adsorption energy and the suppression of HER. These integrated theoretical and experimental results indicate that S-mZVI bm nanoparticles are a promising and innovative material for in situ groundwater TCE remediation.

Batteries face critical challenges in thermal management, including overheating risks, poor interfacial contact, and mechanical vibration–induced performance attenuation. To address these issues, we developed a flame-retardant bio-based thermo-flexible phase-change composite (VHPs) by integrating vanillin-derived polyols (VED), hexachlorocyclotriphosphazene-modified expanded graphite (HPEG), and polyethylene glycol (PEG). The HPEG hybrid filler effectively suppresses the “popcorn effect” of EG while significantly enhancing thermal conductivity, achieving a 246.90% improvement over neat polyurethane (PU). The thermally flexible polyurethane matrix reduces interfacial thermal resistance by 40% at 60 °C due to PEG soft-segment melting, enabling conformal wrapping around batteries. During 36 000 s of charge/discharge cycles, the VHPs reduced the battery temperature by 10 °C and increased the discharge capacity by 53.84% at 3C rates. Compared to the reported phase-change materials, VHPs uniquely integrate flame retardancy (peak of heat release rate reduced to 136.58 kW m −2 ), vibration resistance (compressive strength of 0.28 MPa at 50% strain), and infrared stealth (IR transmittance <0.04% in 3–25 μm). This work provides a sustainable, multifunctional solution for advanced battery thermal management, enhancing both safety and energy efficiency in high-power applications.

Macrolide antibiotics (MAs) are widely used in the fields of medicine, animal husbandry and aquaculture. However, residues due to the overuse of MAs threaten human health and cause ecological and environmental pollution. Aptasensors offer a promising solution for the simultaneous detection of these residues. In this study, a broad-spectrum aptamer (F1-Apt1) with high affinity for MAs was successfully screened using Capture-SELEX technology. Through secondary structure analysis and molecular docking, a truncated 40-nt G-quadruplex-containing aptamer (F1-apt1-40) was obtained, with the dissociation constants (K d ) ranging from 2.62 to 10.72 nM for five MAs. Subsequently, using F1-apt1-40 as the recognition element, a dual-mode aptasensor for detection of MAs was developed. In this sensing configuration, the binding of the targets induces a conformational change in the G4 scaffold of the aptamer, which can be simultaneously reported by (i) colorimetric signal from suppression of the G4/hemin peroxidase-like activity, and (ii) SYBR Green I fluorescence enhancement. The two readouts can be conducted separately in a single reaction system without aptamer modification or complex instrumentation. The dual-mode aptasensor achieved the detection limits of 47.2 nM for colorimetric mode and 60.6 nM for fluorescence mode, respectively. Evaluation experiments using actual samples spiked with MAs achieved the recoveries ranging from 95.46 to 100.86% and the relative standard deviation ranging from 1.60% to 6.10%. Moreover, the entire detection process can be completed in 15 min at room temperature, which offers a low-cost, robust and field-deployable tool for multiplex macrolides surveillance.

Layered double hydroxides (LDHs) hold promise for lithium (Li) extraction from salt-lake brines, owing to their distinctive layered structure and ion-exchange capability. However, the challenge of precisely modulating their electronic structure limits adsorption selectivity and capacity toward lithium-ion (Li + ). Herein, MgAl-LDH nanosheets are anchored on graphene oxide (GO) (GO@MgAl-LDH) via an in-situ growth method to achieve efficient Li + extraction. The experimental and theoretical calculations pinpoint that the hyperfine coupling interaction between GO and MgAl-LDH modulates the electronic structure of interlayer CO 3 2− in MgAl-LDH, thereby optimizing the active sites for Li + adsorption. This hyperfine coupling interaction endows the optimized GO@MgAl-LDH composite with a maximum adsorption capacity of 12.96 ± 0.50 mg·g −1 in simulated salt-lake brine, which is 3.00 and 4.56 times higher than those of pure MgAl-LDH (4.31 ± 0.35 mg·g −1 ) and GO (2.84 ± 0.46 mg·g −1 ), respectively. Practical applications in 11 representative salt-lakes across the Qinghai-Tibet Plateau of China demonstrate that the GO@MgAl-LDH maintains remarkable Li + adsorption performance in real brines, with a maximum adsorption capacity of 5.92 ± 0.18 mg·g −1 in East Taigener Lake. Ecological assessments based on microbial diversity and water quality analyses exhibit that the GO@MgAl-LDH does not induce water quality deterioration, thus ensuring its environmental safety and compatibility.

The rapid and sensitive detection of trace contaminants in food, particularly pesticide residues and migrating packaging additives, remains a critical challenge in food safety monitoring. This has prompted the development of an innovative flexible surface-enhanced Raman scattering (SERS) substrate that overcomes conventional limitations, such as poor enhancement performance, insufficient stability, and narrow spectral response ranges. To address these challenges, this work proposes the strategic assembly of gold nanostars (AuNSs) and gold nanoparticles (AuNPs) on expanded graphite (EG)-modified filter paper to engineer a sandwich-structured SERS-active platform with exceptional broad-spectrum response capabilities, achieving optimal plasmonic coupling. At a 4:1 AuNSs/AuNPs ratio, the substrate generates high-density ‘hot spots’ with a remarkable enhancement factor (4.7 × 10 6 for R6G) and detection limits reaching 10 −9 M, coupled with outstanding thermal stability (20–100 °C) and long-term performance (30 days), while demonstrating practical detection of thiram residues (0.24 ppm, 20 × below US safety limits) and DMSO (1 % v/v), thereby providing fundamental insights into hybrid plasmonic nanostructures while delivering a field-deployable solution for comprehensive food safety monitoring from farm to table.

In this work, a novel graphene-reinforced polyimidazole microsphere catalyst with dual functionality for both CO 2 adsorption and epoxide activation was successfully synthesized via one-step suspension polymerization strategy. This heterogeneous catalyst contained no halogens, effectively mitigating environmental pollution, equipment corrosion, and ensuring product quality. Specifically, graphene was strategically incorporated into the catalyst matrix during synthesis to enhance its thermal stability, and the thermal decomposition temperature has increased by 23 °C. Under optimized reaction conditions, the catalysts with high nitrogen content ( e.g. G-NCHSM-1) achieved the highest yield of cyclic carbonate (99 %) from the cycloaddition of epoxide and CO 2 . Notably, the graphene-reinforced polyimidazole catalyst exhibited favorable stability and potential for industrial applications. Finally, based on the experimental characterizations and density functional theory (DFT) calculations, a possible mechanism for the synthetic cyclic carbonate was proposed, elucidating the synergistic effect of the imine group and C β -H on the imidazole ring in catalyzing the synthesis of cyclic carbonates from CO 2 . Therein, the imine group could capture CO 2 and activate epoxides.

The increasing demand for safe and long-lasting electrochemical energy storage for electric vehicles and portable electronics is driving the development of advanced aqueous zinc-ion hybrid capacitors (AZIHCs). Graphene-based cathodes offer high conductivity and stability, but their performance is hindered by nanosheet stacking and lack of active sites. To overcome this limitation, a dual-modification strategy is proposed, combining molecularly functionalized reduced graphene oxide (PrGO) and flame-reduced graphene oxide (FrGO). The p-phenylenediamine (PPDA) modified PrGO possesses abundant redox-active sites, while the wrinkled FrGO interlayer prevents π-π stacking and enhances interlayer porosity. By adjusting the FrGO/PrGO mass ratio, the composite film (PrGO/FrGO-2) achieves an interlayer-expanded architecture with balanced defect density and conductivity. As a cathode for AZIHCs, it exhibits high gravimetric/volumetric capacitances (348.25F g −1 /176.75F cm −3 ) and exceptional energy densities (107.73 Wh kg −1 ; 59.85 Wh L −1 ). The material retains 93% capacitance after 10,000 cycles. This study introduces a molecular/structural co-optimization approach for designing high-performance flexible electrodes for future energy storage solutions.

Aqueous phase exfoliation (APE) has become a promising method of the graphene preparation. However, it still has some disadvantages, such as low yield and the influence of residual stabilizer on its application. Herein we report a method of the graphene preparation via APE of graphite assisted by sulfonated cobalt phthalocyanine (CoPcS) as the stabilizer. A high yield of graphene can be obtained at low concentration of CoPcS. The yield was 3.2 % in single exploitation, and the total yield reached to 7.3 % after three cycles of exfoliation. The sizes of the prepared graphene sheets were in micron level, and the percentage of few-layer graphene (<5) reached 93 %. The π-π interaction of graphene with CoPcS, as well as the repulsive interaction between negatively charged CoPcS ions, played a crucial role in stabilizing the graphene dispersion. The as-exfoliated graphene powder served directly as a filler in the epoxy coating on the surface of aluminum to improve the protection performance of the coating. A simple, cost-effective, and potential avenue has been provided to product and utilize high-quality graphene materials.

Surface amino-rich GQDs-ε-PL is prepared by changing the addition amount of ε-PL. Then, GQDs-ε-PL@4-arm PEG-BA/QCS hydrogels (GQDs-ε-PL@Gel) are synthesized through dynamic imine bonds cross-linking. The sol can transform quickly to gel and the gelation time can be controlled by adjusting the specific gravity of the input raw materials to water. FT-IR and thermogravimetric analyses indicate the successful synthesis of GQDs-ε-PL and GQDs-ε-PL@Gel. The microstructure observation reveals that GQDs-ε-PL has a sheet-like structure with an average size of 65 nm, while GQDs-ε-PL@Gel has a porous network structure. Both GQDs-ε-PL and GQDs-ε-PL@Gel have good fluorescence stability, photothermal and cytocompatibility, and display better antibacterial effect against Escherichia coli , Staphylococcus aureus and Pseudomonas aeruginosa through chemical and photothermal synergistic sterilization. More importantly, GQDs-ε-PL@Gel can repeatedly self-heal after being damaged, which is more beneficial to provide an effective wound closure environment for wounds and to be used as wound dressings.

Water pollution caused by oil spills and organic solvents have seriously affected the quality of the environment, so the development of green and recyclable oil adsorbents with excellent properties has drawn massive attention from researchers. In this work, bamboo powder (BP) and reduced graphene oxide (GO) were used as raw materials to create a bamboo fiber/graphene aerogel (BGA) aerogel by a green one-pot hydrothermal method. Then, a three-dimensional aerogel super-hydrophobic modified bamboo fiber/graphene aerogel ( H@BGA) with super-hydrophobic properties and a high adsorption capacity was synthesized by using hexadecyltrimethoxysilane (HDTMS) as hydrophobic modification reagent. In this unique ternary aerogel, both bamboo powder and HDTMS could improve the hydrophobicity of the aerogel. Furthermore, the uniformly interspersed bamboo fibers facilitated the exfoliation of graphene, constructing abundant pores and endowing the sample with a large specific area and excellent mechanical properties. The as-prepared H@BGA featured low density, high specific surface area, super-hydrophobicity (WCA = 151.5°), and high adsorption capacity (55–123 g g −1 ). In addition, the adsorption capacity of H@BGA could remain above 95% after 8 cycles of the adsorption/desorption process. Overall, the aerogel has broad application prospects in the field of water/oil separation. © 2022 Society of Chemical Industry (SCI).

Stone-sawing mud (SSM) is a solid waste generated during stone processing, with a presently estimated global production of 30 million m 3 . SSM is usually disposed of in the stone yard, occupying a large area of land and causing serious dust and water pollution. In this study, a novel shape-stabilized composite phase change material (ss-CPCM) containing SSM loaded with NaNO 3 was prepared using the mixing and sintering method for medium-high temperature thermal energy-storage applications. The ss-CPCM retained 50 wt% NaNO 3 without leakage. X-ray diffraction analysis showed good chemical compatibility between the SSM and NaNO 3 , and microscopy analysis demonstrated that NaNO 3 was uniformly distributed within the SSM structure. The compressive strength of the ss-CPCM reached 23.14 MPa. The melting temperature and latent heat of the ss-CPCM are approximately 306.78 °C and 79.86 J·g −1 , respectively, and no significant variations are observed after thermal cycling. The energy storage density of the material is 444.86 J·g −1 in the range of 50–400 °C, and its thermal conductivity is 0.696 W (m·K) −1 . Furthermore, the thermal conductivity of the composites reached 2.421 W (m·K) −1 with the addition of 10 wt% of graphite. Hence, the NaNO 3 /SSM ss-CPCM is considered a promising material for waste heat recovery, thereby providing a valorisation method for the resource utilisation of SSM.

PVA-BB/GO-Fe 3+ /agar hydrogels (BB is configured by 1:1 configuration of 0.04 mol L −1 boric acid solution and 0.04 mol L −1 borax solution) are designed with excellent mechanical and electrical properties due to their triple cross-linked network, and they maintain stable performance in various tests, which is sufficient to support the use of hydrogels in multiple scenarios. Meanwhile, the tension responsiveness of the PVA-BB/GO-Fe 3+ /agar hydrogel allows it to rapidly transmit signal changes upon tension changes. Finally, maintaining increased energy dissipation and strength enhancement during the loading–unloading cycle provides the possibility of long, stable operation. In summary, it is believed that PVA-BB/GO-Fe 3+ /agar hydrogel has significant potential in the field of flexible sensors and is expected to be fabricated as a sensor for motion monitoring.
