Photocatalytic NO oxidation to nitrate (NO 3 − ) is a promising technology for air pollution control. However, these strategies are hindered by slow kinetics as well as unwanted production of toxic NO 2 , which result from the inefficiency in separating charges and poor activation of the reactant molecules. Here, we report on a novel 2D/2D S-scheme heterojunction constructed by coupling CoAl-layered double hydroxide (CoAl-LDH) nanosheets with BiOBr nanoplates. This particular structure enables a S-scheme charge transfer channel that can improve the separation efficiency of photoinduced charge carrier while keeping strong redox ability to generate high-reactive oxygen species (ROS, including hydroxyl radical and superoxide radicals). Furthermore, in situ DRIFTS spectra showed that Co 3+ sites within the LDH framework are key active centers, significantly enhancing NO adsorption and activation. Consequently, the obtained CoAl-LDH/BiOBr composite exhibited excellent NO removal activity, to reach a conversion rate of 97.3% with negligible NO 2 formation (selectivity <3%) under visible light, and maintained excellent stability for 8 h. This study proposes a synergistic strategy of interfacial charge control coupled with surface catalytic site design, providing new perspectives in design of high-performance catalysts for future applications in environmental protection via photo-catalytic processes.

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.

5-Fluorouracil (5-FU) resistance in colorectal cancer (CRC) involves oxidative stress mechanisms, but the role of epitranscriptomic regulation remains unclear. This study investigates how oxidative post-translational modifications of the N6-methyladenosine (m 6 A) methyltransferase METTL16 contribute to 5-FU resistance. Parental (HCT8, HCT15) and 5-FU-resistant CRC cells were compared using redox proteomics, m 6 A-seq, RNA-seq, and functional assays. METTL16 S-glutathionylation was assessed via streptavidin pulldown and mass spectrometry. IGF2BP3’s role was validated through knockdown/overexpression, patient-derived organoids (PDOs), and xenograft models. Clinical relevance was evaluated in 112 CRC patient tissues and data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Drug synergy was tested using isoliquiritigenin (ISO) combined with 5-FU. Resistant cells exhibited elevated global protein S-glutathionylation and reduced m 6 A RNA methylation. METTL16 underwent site-specific S-glutathionylation at Cys548, leading to its degradation and subsequent m 6 A loss. Integrative omics identified IGF2BP3 as a key METTL16 target: reduced m 6 A on IGF2BP3 mRNA enhanced its nuclear export, splicing, and overexpression. IGF2BP3 knockdown sensitized resistant cells to 5-FU in vitro and in vivo, while overexpression conferred resistance. Mechanistically, IGF2BP3 destabilized CFTR mRNA (an ABC transporter), reducing 5-FU uptake. Clinically, high IGF2BP3 correlated with poor survival and 5-FU resistance in CRC patients. Targeting IGF2BP3 with ISO synergized with 5-FU, overcoming resistance in cells and xenografts. Oxidative stress-induced METTL16 S-glutathionylation drives 5-FU resistance by reducing m 6 A modification, enabling IGF2BP3 overexpression and CFTR suppression. IGF2BP3 is a biomarker of clinical resistance, and its targeting with ISO represents a promising combinatorial strategy to restore 5-FU efficacy in CRC.

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.

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.

This work introduces nickel (II) tetraphenylporphyrin (NiTPP) as a multifunctional electrolyte additive to simultaneously address polysulfide shuttle and uncontrolled lithium dendrite growth in lithium–sulfur (Li–S) batteries. Mobile NiTPP species act as homogeneous catalysts with Ni–N 4 centers for rapid polysulfide redox mediation to suppress migration, while planar molecules featuring lithium-affinity capability migrate to the lithium metal surfaces, enabling uniform lithium flux and anode protection. NiTPP-modified electrolytes significantly enhance Li–S battery performance, demonstrated by 634.9 mAh g −1 at 4C, 758.3 mAh g −1 after 100 cycles at 0.2 C (83.4% retention), and 757.5 mAh g −1 under high sulfur loading (2.9 mg cm −2 ) with lean electrolyte ( E / S = 5 μL mg −1 ), all with high Coulombic efficiency. Crucially, NiTPP, acting as a soluble dual-functional mediator enabling homogeneous operation in electrolytes, simplifies Li–S battery fabrication while demonstrating the commercial viability of molecularly engineered mobile active sites for stabilizing both electrodes in high-energy-density Li–S batteries.

Developing porous-structured organic semiconductor photocatalysts with high charge transfer efficiency is crucial for solar energy utilization, yet remains challenging in pollutant remediation. Herein, an S-scheme C-ZnO/B-g-C 3 N 4 photocatalyst with oxygen vacancies was fabricated through modified biomass-derived C doping for methylene blue (MB) degradation. The optimized catalyst achieved 97.8% degradation efficiency within 70 min under visible light. UV-DRS analysis revealed that C doping narrowed the bandgap and enhanced visible-light absorption. XPS results confirmed the S-scheme charge transfer pathway in C-ZnO/B-g-C 3 N 4 . The synergistic effects of C doping and oxygen vacancies significantly improved charge separation and facilitated S-scheme heterojunction formation. The catalyst exhibited superior photocatalytic performance in alkaline conditions and maintained excellent recyclability. Radical trapping experiments identified the primary reactive species as h + > ·O 2 − > ·OH in descending order of contribution. This work provides a promising strategy for solar-driven pollutant remediation by combining biomass-derived carbon modification with S-scheme heterojunction engineering.

Increased safe and environmental awareness in production processes necessitates an ever-growing demand for efficient detection of ethanol/n-butanol/diesel fuel blends (clean energy) in rapid, real time. However, the forces between multiplexed organic molecules in complex environments induce a decrease in the flash point, thus requiring sensors with high selectivity and low-temperature detection capabilities. In this study, an In2O3/WO3 multilevel heterojunction is assembled by utilizing the electrostatic interaction between the hydroxyl group of In(OH)3 and WS2. The material achieves dual detection of ethanol and n-butanol under the excitation of light and temperature fields. It also possesses fast response/recovery times, excellent selectivity, and good long-term stability. The WO3 has a defect-rich (002) exposed surface in the In2O3/WO3 heterojunction, and the special electronic structure of the heterojunction induces carrier migration at the S-scheme heterointerface under photothermal activation, which promotes the generation of more reactive oxygen species (O2–, O–) from the sensing material. The special chemical reaction of the sensor between oxygen anions and the target gas at room temperature (RT) and 120 °C is the basis for the realization of dual-selective detection of ethanol and n-butanol. The sensing mechanism of the WO3/In2O3 heterojunction for ethanol/n-butanol has been systematically investigated based on energy band structure analysis and in situ Raman spectroscopic characterization. This work focuses on the potential of metal oxide-based S-scheme heterojunctions for high-performance gas sensor applications.

We succeed in obtaining Mo 2 C embedded in S-doped carbon (Mo 2 C/SC) nanofibers by electrospinning and sulfuration. The use of S-doped carbon not only provides more additional Na + storage active sites to enhance its sodium storage performance, but also increases electrons migration and ions diffusion. As the anodes for sodium ion batteries (SIBs), the electrode exhibits excellent rate capacities of 242 and 96 mA h g −1 from 0.1 A g −1 to 5 A g −1 . Excitingly, the high-rate performance is superior, achieving 102.7 mA h g −1 at 5 A g −1 over 1000th cycle. This project provides ideas for the development the high-rate and long-term stable of the Mo 2 C in energy storage devices.
