Although MOF-derived materials are promising candidates for microwave absorption, precisely regulating their electromagnetic behavior through microstructure engineering remains a considerable challenge. Herein, a synergistic strategy integrating hollow hierarchical architectures with heteroatom doping is implemented to overcome this limitation. Hollow NiCo-BTC microspheres were employed as the precursor and subjected to calcination in the presence of melamine, which induced the in-situ growth of carbon nanotubes on the surface to form hierarchical hollow NiCo@NCNTs architectures. Subsequent sulfur doping via chemical vapor deposition (CVD) yielded NiCo@NCNTs/S composites with tunable sulfur contents. The hollow architecture significantly enhanced impedance matching and facilitated multiple scattering of microwave within the structure. The hierarchical nanostructures constructed abundant heterogeneous interfaces, effectively augmenting interfacial polarization. Crucially, the coexistence of surface sulfoxides, thiophenic sulfur, and structural defects synergistically modulates the electronic structure. This multi-faceted regulation elevates free electron density while introducing additional dipole and defect-induced polarization centers, thereby establishing an optimal equilibrium between conduction loss and polarization loss. Consequently, the optimized NiCo@NCNTs/S-5 composite exhibited exceptional microwave absorption performance, achieving a maximum reflection loss of −39.73 dB and an effective absorption bandwidth of 4.56 GHz with a thin thickness. This work elucidates a rational design paradigm for MOF-derived absorbers through hollow-hierarchical morphology control and heteroatom doping regulation, offering a viable pathway toward high-performance microwave absorption for practical applications. The integration of hollow hierarchical structure construction and sulfur doping enables precise modulation of the electromagnetic properties of the material. The hollow architecture optimizes impedance matching and triggers multiple microwave scattering, while the hierarchical nanostructures afford abundant heterogeneous interfaces to strengthen interfacial polarization. Sulfoxide groups, thiophene-type sulfur species and structural defects coexist on the material surface, synergistically tuning the electronic structure. This multidimensional regulation strategy elevates the free electron concentration and simultaneously introduces dipole and defect polarization centers, balancing conductive loss and polarization loss. The optimized NiCo@NCNTs/S-5 absorber achieves a minimum reflection loss (RL max ) of −39.73 dB and an effective absorption bandwidth (EAB) of 4.56 GHz at a thickness of 2 mm.

Post-equilibrium displacement induced secondary release of pre-adsorbed dye. • Congo Red remobilized pre-adsorbed Alizarin Red S in binary systems. • A clear CR > ARS competitive retention hierarchy drove asymmetric displacement. • DFT/IGMH supported stronger multi-site interfacial interactions of Congo Red. • Competitive displacement tests improve adsorbent risk evaluation. Competitive adsorption in multicomponent wastewater can induce post-equilibrium displacement and remobilization of previously adsorbed pollutants. Here, CCS@NH 2 -MWCNTs was used as a model composite interface to investigate the competitive adsorption and displacement of Congo Red (CR) and Alizarin Red S (ARS). CR exhibited stronger competitive retention than ARS: CR displaced 59.90% and 64.87% of pre-adsorbed ARS at 30 and 40 °C, respectively, whereas reverse displacement remained below 1% at 30 °C and no measurable CR release was detected at 40 °C. Preferential CR retention was maintained over an initial pH range of 4–10. Spectroscopic characterization and DFT/IGMH analyses suggest that charge distribution, extended π-conjugation, multi-site interactions, and interfacial accessibility collectively contribute to the observed retention hierarchy. These findings show that apparent adsorption equilibrium does not necessarily ensure persistent contaminant immobilization and highlight post-equilibrium displacement as a potential secondary-release mechanism relevant to multicomponent wastewater treatment.

Ce-doped Bi 7 O 9 I 3 /TiO 2 S-scheme heterojunction was constructed for PNRR. • Ce doping modulates the Fermi level and strengthens the built-in electric field. • The enhanced BIEF promotes directional charge transfer across the heterojunction. • Strengthened charge separation improves photocatalytic N 2 fixation performance. • N 2 reduction proceeds via an associative distal reaction pathway. Photocatalytic nitrogen fixation offers a sustainable route for ammonia synthesis under ambient conditions, but its practical application is severely limited by inefficient charge separation and sluggish interfacial charge-transfer kinetics. Herein, we develop a Ce-doped Bi 7 O 9 I 3 /TiO 2 S-scheme heterojunction through dopant-mediated Fermi level engineering to strengthen the interfacial built-in electric field (BIEF) and enhance photocatalytic nitrogen fixation. The charge transfer behavior and N 2 reduction mechanism was investigated using photoelectrochemical measurements, Kelvin probe force microscopy (KPFM), ultraviolet photoelectron spectroscopy (UPS), theoretical calculations, and in situ FT-IR spectroscopy. Ce doping shifts the Fermi level of Bi 7 O 9 I 3 upward, thereby enlarging the Fermi level difference between Bi 7 O 9 I 3 and TiO 2 and strengthening the interfacial BIEF. The enhanced BIEF promotes directional interfacial charge transfer and suppresses photogenerated carrier recombination, leading to improved charge separation. Consequently, the optimized photocatalyst achieves an NH 3 production rate of 53.70 μmol g −1 h −1 in pure water, which is 8.21- and 3.76-fold higher than those of pristine Bi 7 O 9 I 3 and the undoped Bi 7 O 9 I 3 /TiO 2 heterojunction, respectively. In situ FT-IR spectroscopy and theoretical calculations indicate that the photocatalytic nitrogen reduction proceeds through an associative distal pathway. This work demonstrates that dopant-induced Fermi level engineering can effectively regulate interfacial electric fields and charge transfer behavior in S-scheme heterojunctions, providing a rational strategy for BIEF engineering in efficient photocatalytic nitrogen fixation.

The P/S doped carbon nanosheets (PSCN) were prepared by one-step method. • PSCN exhibits uniform N, S doped, porous structures and abundant defect sites. • The PSCN presents large Zn 2+ ion diffusion coefficient of 1.07 × 10 −6 cm 2 s −1 . • PSCN cathode displays long cycle life with capacity increase of 0.29% after 50,000 cycles. Aqueous zinc-ion hybrid capacitors have become an attractive option in the fields of energy storage on account of their inherent affordability and enhanced safety features. However, there is room for significant improvement in terms of energy density and specific capacity in current state. To solve this problem, we propose a strategy to improve the surface characteristics of carbon nanosheets (CNs) by synergistically incorporating P/S heteroatoms and pore engineering. The doping of P/S heteroatoms not only furnish defect sites, but also facilitates the redox reaction between Zn 2+ and oxygen functionalities. Additionally, the pore engineering enables the formation of multiple ion adsorption sites and transport channels in the CNs. Meanwhile, the KI additive introduces reversible I − /I 3 − redox reactions on the cathode, contributing extra faradaic capacity, and stabilizes the Zn anode by regulating Zn 2+ deposition and suppressing side reactions. Therefore, the PSCN cathode displays interesting zinc ion storage merits, e.g. large discharge capacity of 284.29 mAh g −1 at 0.1 A g −1 , excellent energy density of 240.72 Wh kg −1 and long cycle life with capacity increase of 0.29% after 50,000 cycles. This study affords a route to boost Zn 2+ storage performance by the synergetic effect of heteroatoms, pore engineering and ion additives.

Dual-mode optical probes that are low-cost, sustainable, and stable over long periods are attractive for fieldable chemical and temperature readouts. We report a one-pot hydrothermal synthesis of nitrogen- and sulfur-codoped carbon dots (N, S-CDs) from fennel and garlic. The N, S-CDs exhibit green emission (λex/λem ≈ 459/525 nm) with a quantum yield of 9.98%. As a Fe³⁺ fluorescent probe, the material shows a linear response over 20–100 μM with a limit of detection of 0.37 μM (3σ/k). As a thermometric probe, the fluorescence intensity decreases linearly from 0–100 °C with a relative sensitivity of 0.58% °C⁻¹, accompanied by a progressive blue shift that enables intuitive colorimetric readout. After one year of ambient storage, the thermometric performance remains essentially unchanged (e.g., intensity variation at 0 °C ≤ ~4%), underscoring exceptional long-term stability. The combination of green synthesis, dual-function sensing (Fe³⁺ and temperature), and year-long durability positions these N, S-CDs as a practical platform for environmental monitoring and low-power visual thermometry.

The development of polymeric materials combining high thermal resistance and solution processability is critical for chemical and energy engineering. Herein, dibenzothiophene-bridged bisphthalazinone (T-BDHPZ) units are incorporated into poly(aryl sulfone ketone)s (PTPSKs) to simultaneously achieve extreme heat resistance, solubility, and intrinsic flame retardancy. The resulting PTPSKs exhibit high glass-transition temperatures (388–404 °C), decomposition temperatures above 500 °C, and char yields exceeding 64%. The noncoplanar heteroaromatic backbone generates substantial free volume and efficient chain disorder, enabling solution fabrication of high-performance films and coatings. The PTPSK films show tensile strengths of 90.5–93.2 MPa, storage moduli of 3.41–3.74 GPa, high modulus retention at 300–350 °C, optical transparency (73–76% at 800 nm), and low dielectric constants (2.95–3.09 at 1 MHz). Notably, PTPSK films achieve UL-94 VTM-0 without additives. The PTPSK coatings also display strong adhesion, high hardness, corrosion resistance up to 450 h, and solvent-based recyclability. These features make PTPSKs promising for high-temperature coatings and electronic insulation.

To address the prevalent problems of rapid photogenerated carrier recombination and insufficient redox capacity in photocatalytic hydrogen evolution, this work constructs a ZnWO 4 /Mn 0.2 Cd 0.8 S (ZWO/MCS) heterojunction photocatalyst featuring an S-scheme band structure. The addition of ZnWO₄ (ZWO) significantly boosts the photocatalytic activity of Mn 0.2 Cd 0.8 S (MCS). Under irradiation with simulated visible light, the 20ZWO/MCS composite exhibited the highest hydrogen production rate (30.22 mmol·g −1 ·h −1 ), 44.44 times that of pure ZWO and 4.51 times that of pure MCS, respectively. It also demonstrates excellent catalytic stability during continuous cycling tests. Through a systematic investigation of its structure, optoelectronic properties, and photocatalytic hydrogen evolution performance, combined with density functional theory (DFT) theoretical calculations, it was confirmed that a tight heterointerface forms between ZWO and MCS, establishing an S-scheme interfacial charge transfer route driven by the internal electrical field (IEF). Through the pathway, the photogenerated charges are efficiently separated spatially, with electrons enriched in the conduction band of MCS for proton reduction for hydrogen production, while holes gather within the valence band of ZWO. The study deepens the understanding of the behavior of charge carriers in S-scheme heterojunctions regarding their separation and migration, providing theoretical foundations and material design strategies for developing high-performance photocatalytic systems. Combined with in-situ experimental characterization and DFT theoretical calculations, it has been confirmed that the built-in electric field (IEF) formed by the difference in work function drives the migration of photo generated electrons from ZWO to MCS, following an S-shaped charge transfer path, achieving efficient spatial separation of charge carriers.

A bottom-gate-modulated carbon-based FET is developed for room-temperature H 2 S detection. • Complete recovery is achieved by purely electrical activation without external assistance. • The sensor shows favorable selectivity and stability for miniaturized, integrated sensing applications. Increasing attention has been paid to the detection of hazardous gases under room-temperature operating conditions. To address this, this work proposes a novel strategy based on a bottom-gate modulated carbon-based field-effect transistor (FET) for efficient room-temperature H₂S sensing. The FET-type gas sensor was constructed by integrating ZnWO₄/WO₃ composites with the carbon nanotube channel. It was found that applying a −1.5 V bottom-gate bias effectively modulates the surface electronic states of the sensing material, leading to significantly enhanced device performance: a response time of 28 s and a recovery time of 92 s toward 10 ppm H₂S at room temperature, enabling both rapid response and complete recovery. Furthermore, the sensor exhibits a favorable concentration-dependent response within 1–10 ppm, while maintaining high selectivity, consistent reproducibility, and durable long-term stability (maximum response fluctuation <7.1% over 15 days). The performance enhancement is primarily attributed to the gate-bias-facilitated regeneration of adsorbed oxygen species on the material surface. This work not only provides an innovative approach for room-temperature, low-power H₂S detection but also offers a new pathway toward the development of miniaturized and integratable gas sensors.

Structural polymerization is a primary factor driving intrinsic property changes in calcium silicate (aluminate) hydrate (C–(A)–S–H). However, the mechanisms by which erosive media induce structural polymerization of C–(A)–S–H gel during the service life of cement-based materials remain unclear. This study investigates the effects of both alkaline and acidic sulfates on the composition and microstructural evolution of C–(A)–S–H through various physical and microstructural analyses. The findings indicate that dehydration condensation reactions of Si–OH groups, resulting from decalcification and carbonation processes, are the main contributors to the polymerization silicate tetrahedra. As the aluminum phase increases, the leaching of Al[IV] from the C–(A)–S–H gel after sulfate erosion becomes more pronounced, leading to a tendency for the original silicate–aluminate chain structure to undergo polymerization and reconstruction. Furthermore, aluminum can only promote the polymerization of silicate tetrahedra within a specific range. This study provides a theoretical foundation for regulating concrete microstructure and optimizing its durability.

Construct TiO 2 @MIL-101-Fe S-scheme via impregnation in situ hydrolysis. • Hierarchically distributed TiO 2 maximizes interfacial contact. • Achieves 13.91% cyclohexane conversion and retains high activity after five cycles. • Interfacial fields drive spatial charge separation and preserve redox potentials. • Hierarchical confinement and pore-mouth anchoring enable selective C H activation. The selective photocatalytic oxidation of cyclohexane is a sustainable and environmentally friendly route for KA-oil production, yet it remains limited by low conversion, moderate selectivity, and inefficient charge utilization. This study employed an in-situ TBOT hydrolysis strategy to synthesize a TiO 2 @MIL-101-Fe S-scheme heterojunction with hierarchically distributed TiO 2 nanodomains within the MOF pores, at pore mouths, and on the external surface. This spatially engineered heterostructure enhances photogenerated carrier separation, stabilizes the interface, and improves cyclohexane oxidation efficiency and KA-oil selectivity. The optimized 50 wt% composite material achieved a cyclohexane conversion rate of 14.3%, which was 2.17 times that of the original MIL-101-Fe material. Meanwhile, it still maintained a cyclohexane conversion rate of up to 13.9% and excellent catalytic activity after five cycles. Steady-state and time-resolved photoluminescence, electrochemical impedance, and transient photocurrent measurements reveal accelerated charge separation and prolonged carrier lifetime, enabled by an S-scheme heterojunction with a built-in interfacial electric field. Radical trapping and ESR studies indicate that photogenerated holes and electrons dominate C H activation, with reactive oxygen species contributing synergistically. DFT calculations confirm directional electron transfer and preserved high redox potentials. This work highlights spatially confined S-scheme heterojunctions as a general strategy to enhance photocatalytic efficiency, selectivity, and stability, offering a promising avenue for solar-driven hydrocarbon oxidation.

Rhabdomyolysis-induced acute kidney injury (RM-AKI) is a life-threatening clinical condition characterized by excessive myoglobin release, leading to kidney tubular obstruction, oxidative stress, and iron-mediated lipid peroxidation. However, current therapies fail to effectively suppress oxidative stress cascades and lack kidney targeting. Herein, we developed a kidney-targeted nanodrug delivery system with multimodal antioxidant functionality (DFO@SOC) for RM-AKI therapy. Using antioxidant capacity as the decisive screening criterion, Se/S co -doped onion-derived carbon dots (SOC) were identified as the optimal nanocarrier through systematic natural polyphenol precursor selection and heteroatom-doping optimization. SOC exhibited pronounced superoxide dismutase-like and catalase-like activities. The iron chelator deferoxamine (DFO) was subsequently loaded onto SOC, yielding uniformly sized, negatively charged DFO@SOC nanoparticles. In vitro studies demonstrated efficient cellular uptake, robust intracellular scavenging of reactive oxygen species (ROS) and iron ions, and negligible cytotoxicity. In an RM-AKI mouse model, DFO@SOC selectively accumulated in injured kidneys. Notably, Sound Touch Visco-elastography (STVi) and Quantitative Tissue Scattering Coefficient (QTSC) enabled noninvasive and real-time evaluation of therapeutic efficacy with kidney stiffness decreasing significantly from ~14 to 7 kPa. Combined biochemical and histopathological analyses, DFO@SOC treatment significantly reduced Scr from ~193.31 to ~93.82 μmol/L and blood urea nitrogen (BUN) from ~52.99 to ~30.68 mmol/L compared to the model group. In summary, the synergistic antioxidant and iron-chelation effects of DFO and SOC, establishing DFO@SOC as a promising nanotherapeutic strategy for RM-AKI.

Interfacial engineering in heterostructure photocatalysts is crucial for efficient charge migration, yet achieving rational and controllable interface design remains a major challenge. In this work, SnIn 4 S 8 nanosheets were in situ grown on the octahedral surface of MIL-101(Cr) to leverage the Lewis acid-base properties of Cr and S, thereby enabling the controlled construction of an ion-coordinated interface. The resulting MIL-101(Cr)@SnIn 4 S 8 heterojunction enabled efficient capture and conversion of CO 2 and H 2 O. Furthermore, the Lewis acid-base coordination induces interfacial electron density redistribution, generating a built-in electric field that drives the formation of an S-scheme heterojunction between MIL-101(Cr) and SnIn 4 S 8 , while simultaneously preserving high‑energy photogenerated electron-hole pairs. Consequently, MIL-101(Cr)@SnIn 4 S 8 exhibited superior CO 2 photoreduction performance with H 2 O in the gas-solid phase, delivering a CO evolution rate of 26.9 μmol·g −1 ·h −1 . This work provides a viable strategy for interfacial engineering and demonstrates the application potential of S-scheme heterojunctions in photocatalytic reactions.
