This study investigates the fate of polystyrene nanoplastics (PS) in porous media under the individual and combined effects of different forms of P. It was shown that under the effect of different P forms, the migration rate of PS was: PS-PA + nHAP > PS-PA > PS-PO4 > PS > PS-PO4 + nHAP > PS-nHAP, which indicated that PO4 alleviated the inhibitory effect of nHAP on the transport of PS, while coexistence of PA and nHAP produced significant synergistic facilitation effect on the transport of PS. The results of various characterization techniques, classical or extended Derjaguinee-Landauee-Verweyee-Overbeek (DLVO/EDLVO) theory, and density function theory (DFT) calculations revealed that the adsorption of PO4 increased the negative electronegativity of the heterogeneous aggregates of PS and nHAP, alleviating the inhibitory effect of nHAP on the transport of PS by enhancing electrostatic repulsion. And PA was adsorbed on the surfaces of nHAP and PS, respectively, increasing the electrostatic interaction and steric effect between PS and the media, which synergistically promoted the transport of PS. Among them, the steric effect between PS and nHAP after adsorption of PA was the main factor for synergistic promoted PS transport. This study provides theoretical support for the development of predictive models for nanoplastic transport in phosphorus-rich environments and risk management strategies.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"66 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The related technical route comprises electrodeposition, electro-exfoliation, and electrolytic redox, and the resultant materials have demonstrated impressive functional enhancements. This review begins with a concise overview of compositions, characteristics, and applications of the deep eutectic solvents.

The deep eutectic solvents discussed are limited to those derived from choline quaternary ammonium salts, especially Reline, Ethaline, and Glyceline. The synthesis includes electrodeposition to synthesize elementary substances, bimetallic alloys, trimetallic alloys, and metal-nonmetal compounds. The electrochemical process involves electro-exfoliation to produce two-dimensional materials, exemplified by graphene. The preparation also covers the electrolysis to prepare metallic oxides.

The introduction of an interfacial air layer between the carbon fiber core and SiC nanofibers significantly improved impedance matching and interfacial polarization. As a result, the composite achieves a minimum reflection loss (RLmin) of −59.21 dB at 6.96 GHz (2.30 mm thickness) and a maximum effective absorption bandwidth (EABmax) of 2.48 GHz at 1.0 mm. Additionally, the air-layer architecture imparts improved thermal insulation, when placed on a 357.3 °C hot surface, the composite's outer surface remains as low as 128.8 °C (after 5 min), indicating its promise for multifunctional thermal management applications.

Nevertheless, its practical implementation faces critical challenges including restricted light-harvesting capacity and inefficient charge carrier dynamics, which substantially compromise photocatalytic efficiency. To address these limitations, we propose a novel Z-scheme heterojunction (denoted as OCN/CdS) by strategically integrating cadmium sulfide quantum dots (CdS QDs) with defect-engineered oxygen-doped g-C3N4 nanosheets (OCN). The designed architecture integrates quantum confinement effects from CdS QDs, tailored defect states in OCN, and interfacial electric field enhancement through Z-scheme charge transfer pathways. The optimized OCN/CdS-2 heterojunction exhibits enhanced photocatalytic activity, achieving a tetracycline degradation rate (kapp) of 0.031 min−1 and a hydrogen evolution rate of 5270 μmol·g−1·h−1. These values correspond to 3.4-fold and 21-fold improvements compared to pristine g-C3N4, respectively. Mechanistic investigations reveal that the OCN/CdS-2 Z-scheme heterojunction simultaneously maximizes active site exposure and establishes robust built-in electric fields at interfaces, which collectively suppress charge recombination while accelerating redox reaction kinetics.

Although glassy polymers typically possess high tensile strength (10–100 MPa), it remains challenging to preserve their outstanding mechanical properties upon solvation and gelation. Moreover, appropriate technique for continuously spinning glassy ionogel fibers is still lacking. Herein, we propose a biomimetic spinning strategy for directly drawing glassy ionogel fibers with designable mechanical and electrical properties. Ionic liquids play critical roles as plasticizer and solvent cross-linker for regulating the rheological behavior of pre-polymerized dope and guaranteeing the success of continuous fiber spinning. The ionogel fibers exhibit tailorable tensile strength (from 1.44 to 61.51 MPa), Young's modulus (from 0.64 MPa to 3.08 GPa), extensibility (from 5.13 to 541.20 %) and toughness (from 1.43 to 60.27 MJ m−3), together with 98 % damping capacity, excellent transparency and optimal ionic conductivity of 4.67 × 10−2 S m−1. These fibers can be woven to build an artificial cobweb with the capability for camouflage, capture, and sensing.

These structures facilitate efficient water transport, broad-spectrum light absorption, and rapid vapor escape. More importantly, the hierarchical system enables multistage energy utilization by coupling direct solar absorption with passive environmental energy harvesting and latent heat recycling from upper to lower evaporation stages. As a result, the 9-stage evaporator attains an exceptionally high evaporation rate of 6.12 kg m−2 h−1 for 1 h under 1-sun (1 kW m−2) without external energy input, significantly surpassing the thermodynamic limit of conventional single-stage systems. The system also exhibits excellent long-term stability and salt rejection in continuous desalination tests.
