The detailed reaction pathway for the aluminothermic reduction of TiO 2 has remained elusive due to its characteristically ultra-fast, combustion-like nature. This study systematically elucidates the reaction pathway of the CaO- and CaCl 2 -assisted aluminothermic reduction of TiO 2 for the precise fabrication of Ti 2 O, employing TG-DSC, high-temperature in-situ XRD, and SEM-EDS. The process involves multiple titanium-bearing intermediates, such as Ti 2 O 3 , TiO, CaTiO 3 , CaTi 2 O 4 , and TiAl 3 . The transient formation of TiAl 3 during the initial rapid-reaction stage deviates from the thermodynamically predicted pathway, attributed to localized over-reduction caused by non-uniform Al distribution and intense exothermic heat. The overall process evolves through three distinct temperature-dependent stages (< 660 °C, 660 °C to 772 °C, > 772 °C). The synergistic roles of CaO and CaCl 2 are essential. CaO acts as a thermodynamic coupling agent to enhance the driving force, while CaCl 2 serves as a kinetic accelerator to facilitate mass transfer, collectively enabling the precise fabrication of Ti 2 O.

Silicon-based materials have garnered significant attention as promising anode candidates for next-generation lithium-ion batteries due to their high theoretical specific capacity, low operating voltage, and abundant natural resources. However, the practical application of silicon anodes is severely hindered by their excessive volume expansion (> 300%) during charge/discharge cycles, leading to electrode pulverization. In recent years, the volume expansion of silicon anodes can be effectively alleviated through nanostructured design and carbon-based composite methods. In this work, silicon nanotubes synthesized via low-temperature aluminothermic reduction of natural halloysite served as the substrate. Core–shell structured silicon/carbon composites were successfully fabricated through liquid-phase coating and thermal treatment using sucrose, glucose, phenolic resin, soluble starch, and pitch as carbon sources. Experiments confirm that amorphous pyrolytic carbon derived from sucrose pyrolysis uniformly coats the silicon nanotubes, enhancing both structural stability and electrical conductivity of the composite material. The existence of the carbon layer effectively buffers the volume expansion of silicon during the charge and discharge process and prevents the structural rupture and pulverization of silicon nanotubes, thereby improving cycle stability and rate performance. When used as an anode for lithium-ion batteries, the sucrose-derived carbon-coated silicon nanotubes composite exhibited the optimal electrochemical performance. It delivered a high initial discharge capacity of 2321.4 mAh g −1 and an initial coulombic efficiency of 82.3% at a current density of 0.2 A g −1 . Furthermore, it retained a reversible capacity of 1488.4 mAh g −1 after 500 cycles, corresponding to a capacity retention rate of 64.1%. This work provides valuable insights into the selection of carbon sources for preparing high-performance silicon/carbon composites, offering a promising pathway to accelerate the commercialization of silicon-based anode materials.

Di(2-ethylhexyl) phthalate (DEHP) is a widespread organic pollutant in aquatic environments, which possesses reproductive toxicity and endocrine-disrupting effects. Conventional detection methods often rely on bulky instrumentation, incur high costs, and require complex sample preparation, limiting their suitability for rapid or on-site analysis. Therefore, we developed a molecularly imprinted electrochemical electrode sensor using a hybrid platform of gold nanoparticles (AuNPs) and multi-walled carbon nanotubes (MWCNTs) for the sensitive and convenient detection of DEHP. The sensor was constructed by co-modifying a boron-doped diamond (BDD) electrode with MWCNTs and AuNPs, followed by the in situ electrochemical polymerization of a DEHP-specific molecularly imprinted polymer layer. The resulting electrode exhibited excellent electrochemical activity and selective molecular recognition. Electrochemical impedance spectroscopy and frequency response analysis were used to characterize charge transfer resistance and interfacial capacitance over a DEHP concentration range of 1–50 ppm. In addition, principal component analysis was applied to explore the relationship between interfacial electrical parameters and sensing behaviors. Validation with real samples confirmed the sensor’s capability to detect DEHP across varying concentrations. Therefore, the molecularly imprinted AuNPs/MWCNTs/BDD electrode sensor demonstrates high sensitivity, excellent selectivity, and operational simplicity, offering a promising strategy for the on-site monitoring of small-molecule environmental contaminants.

A collection of oxyapatite-structured Ba 2 La 3 (SiO 4 ) 2 (PO 4 )O doped with varying amounts of Tb 3+ ions (denoted as BLSPO: x Tb 3+ ) was prepared via the high-temperature solid-state reaction. The study comprehensively explored the crystalline characteristics, photoluminescence behaviors, and potential applications in LED devices. The XRD results confirmed its phase purity. Photoluminescence and excitation spectra analyses revealed that the optimal excitation wavelength for BLSPO: x Tb 3+ phosphors is 378 nm. Under this excitation, four sharp emission peaks were observed at 491 nm ( 5 D 4 → 7 F 6 ), 546 nm ( 5 D 4 → 7 F 5 ), 591 nm ( 5 D 4 → 7 F 4 ), and 626 nm ( 5 D 4 → 7 F 3 ). The best luminescent performance was achieved when the Tb 3+ ion doping concentration was 10 mol%. The concentration quenching mechanism can be effectively explained by dipole–dipole interactions. Additionally, the thermal stability of two samples, BLSPO:10 mol%Tb 3+ and BLSPO:20 mol%Tb 3+ , was tested. The results indicated an anomalous thermal quenching behavior, where the luminescence intensity increased with temperature rather than decreased. Specifically, the luminescence intensity of the BLSPO:10 mol%Tb 3+ sample increased to 112% of its initial value at 480 K, while that of the BLSPO:20 mol%Tb 3+ sample reached 111% at the same temperature, demonstrating exceptional thermal stability. When BLSPO:10 mol% Tb 3+ samples were used to fabricate green and white LEDs, their CIE chromaticity coordinates were (0.369, 0.512) and (0.323, 0.342), respectively, falling within the green and white regions of the chromaticity diagram. This demonstrates the material’s broad application prospects in LED lighting and display technologies.

The development of high-capacity and easily separable adsorbents is crucial for efficient dye wastewater treatment. Herein, a magnetic Fe 3 O 4 @ZIF-67 nanocomposite was synthesized via a facile in situ method to enhance its separation and recovery capabilities. The characterization results confirmed the successful synthesis of this nanocomposite. The batch adsorption experiments demonstrated that its adsorption capacity reached as high as 949.5 mg·g −1 . This process can be well described by the Langmuir and pseudo-second-order models, indicating it is a single-layer chemical adsorption. The thermodynamic studies revealed the adsorption to be spontaneous and endothermic. This work not only presents Fe 3 O 4 @ZIF-67 as a highly efficient and recyclable adsorbent for malachite green (MG) but also validates the strategy of constructing magnetic MOF-based composites for practical environmental remediation.

S100A10 protein, a member of S100 protein family, has been extensively studied in mammalian models. In fish species, evolution of S100 proteins including S100A10 has been clarified, revealing that two paralogous genes, S100A10a and S100A10b , arose in teleosts through the fish-specific whole-genome duplication event. However, the functional roles of fish S100A10 genes remain largely uncharacterized. In the present study, we identified two S100A10 homologs in grass carp, designated gcS100A10a and gcS100A10b, and demonstrated that their mRNA is highly expressed in grass carp skin and strongly upregulated after skin trauma by real-time quantitative PCR. Using the fish epithelial cell line, Epithelioma papulosum cyprini (EPC) cells, as a model, we showed that overexpression of gcS100A10a or gcS100A10b enhances cell viability, increases expression of proliferating cell nuclear antigen (PCNA), and promotes DNA synthesis, thereby demonstrating their capacity to stimulate cell proliferation. Flow cytometric analysis further uncovered that both proteins accelerate EPC cell cycle progression by promoting transition into the S and G2/M phases. Additionally, gcS100A10a and gcS100A10b significantly elevate EPC cell migration and this elevation is attenuated by a broad-spectrum matrix metalloproteinase (MMP) inhibitor, GM6001, suggesting involvement of MMP activity in this process. This suggestion is strongly supported by findings that overexpression of gcS100A10a or gcS100A10b increases extracellular MMP activity and decreases intracellular MMP accumulation although MMP-2 / MMP-9 mRNA levels remain unchanged. Collectively, these results demonstrate the positive regulation of gcS100A10a and gcS100A10b on fish epithelial cell proliferation and migration, together with their high and injury-inducible expression in grass carp skin, indicating their possible involvement in fish skin wound healing.

High-nickel layered material LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) is one of the most promising cathode materials for lithium-ion batteries because of its high specific capacity, low cost, and high working voltage. However, issues such as internal structure collapse and interface side reactions during long-term cycle hinder its practical application. In this study, Al, B, La, Nb, and Zr are selected for high-entropy doping of single-crystal NCM811 (SNCM811). Individual doping elements offer distinct advantages in optimizing the morphology, crystal structure, and lithiation/delithiation performance. A portion of the introduced Nb is uniformly coated on the material surface as LiNbO 3 . The resulting material, modified by high-entropy doping coupled with a LiNbO 3 coating (HE-SNCM811) exhibits a capacity retention of 91.5% after 100 cycles at 1 C in the voltage range of 2.7–4.3 V, which is significantly higher than the 73.6% retention of the pristine sample. At 10 C, HE-SNCM811 delivers a reversible specific capacity of 152.82 mAh‧g −1 which is 17.26 mAh‧g −1 higher than that of the pristine sample. The first-principles calculations are performed on the crystal structures of the pristine sample and the heterojunction structure formed between the high-entropy doped bulk phase and the LiNbO 3 coating. Compared to SNCM811, HE-SNCM811, exhibits a 0.18 eV reduction in the Li + migration energy barrier, along with an enlarged Li layer spacing and a reduced transition metal (TM) layer spacing. This enhanced Li + diffusion kinetics and stabilizes the microstructure of the material. The high-entropy modification widens the Li + transmission channel, strengthens the TM–O bonds, and effectively suppresses the irreversible H2–H3 phase transition. Additionally, the LiNbO 3 coating, as a fast ionic conductor, physically isolates the electrolyte, reduces HF attack, and prevents degradation of the cathode surface. This study offers a research approach for developing high-capacity and long-cycle cathode materials for lithium-ion batteries. Graphical abstract In this work, Al, B, La, Nb and Zr are introduced as high-entropy dopants, while Nb partially forms a LiNbO 3 coating on the surface, yielding the HE-SNCM811 cathode material. The modified sample exhibits high rate capability and stable cycling performance. First-principles calculations reveal a lower Li + migration barrier and a higher Li + diffusion rate in the high-entropy modified sample.

With the growing demand for insulating paper with low dielectric loss, high mechanical strength, and excellent thermal stability in advanced electrical equipment, the development of high-performance fiber-based composite insulation materials has attracted increasing attention. In this study, dopamine modification of Kevlar pulp (KP) was employed to enhance the dielectric, mechanical, and thermal properties of KP/softwood pulp (SWP) composite insulating paper. Composite insulating papers with different blending ratios of dopamine-modified Kevlar pulp (MKP) and SWP were prepared, with conventional Kraft paper used for comparison. The effects of dopamine treatment on interfacial structure and on the electrical, mechanical, and thermal properties of the composite papers were systematically investigated. The results show that dopamine modification significantly improves the interfacial adhesion between KP and SWP, suppresses molecular polarization, and reduces both the dielectric constant and dielectric loss. Among the prepared samples, the paper containing 20 wt% MKP and 80 wt% SWP exhibited the best dielectric performance, with a dielectric constant 18.53% lower than that of Kraft paper. In addition, dopamine modification effectively reduced interfacial defects between the two fiber phases, strengthened the fiber network structure, and increased the tensile strength by 38.4% compared with the unmodified composite paper. The dopamine-modified composite paper also demonstrated superior thermal stability and electrical performance. These results indicate that dopamine modification is an effective strategy for fabricating low-dielectric, high-strength composite insulating paper, providing a promising route for the development of high-performance insulating materials for electrical applications.

Among high-performance, clean, safe, and cost-effective energy storage technologies, supercapacitors have emerged as one of the most promising solutions for harnessing and delivering non-fossil energy. In this work, a sustainable biomass-derived carbon-coconut shell carbon (CSC) was employed as both a conductive scaffold and carbon source to support vanadium nitride (VN) via a hydrothermal synthesis route, yielding a CSC@VN composite. To further enhance electrochemical stability, the composite was subjected to a surface carbon-encapsulation treatment, resulting in a unique sandwich-structured CSC @VN@ amorphous carbon (CSC@VN@AC) material. The as-prepared CSC@VN composite delivered a specific capacitance of 122.3 F g⁻ 1 at a current density of 1 A g⁻ 1 and retained 79% of its initial capacitance after 8,500 charge–discharge cycles, demonstrating respectable cycling stability. Remarkably, the carbon-encapsulated CSC@VN@AC exhibited an improved specific capacitance of 129.81 F g⁻ 1 under the same conditions, along with significantly enhanced long-term cycling performance because of carbon-encapsulated. This enhancement is attributed to the protective amorphous carbon layer, which mitigates structural degradation and improves interfacial charge transfer during repeated electrochemical operation.

Non-metallic cationic polymerization of low-reactivity styrene (St) derivatives remains challenging due to broad molecular weight distributions and rapid deactivation of active species. Here we show that adding only a minor amount of CH 3 CN ( V/V , 3/97) to the conventional BF 3 ·OEt 2 /COH/CH 2 Cl 2 /St system affords polystyrene with narrow dispersity ( M w / M n , Đ ≈ 1.3). Notably, the M n increases linearly with conversion and closely matches the M n.calcd . 1 H-nuclear magnetic resonance ( 1 H-NMR) analysis and comparative experiments with the BF 3 ·CH 3 CN co-initiation system indicate CH 3 CN does not coordinate strongly with BF 3 compared to diethyl ether (OEt 2 ); however, it stabilizes the propagating carbocation and decreases the the propagation rate constant ( k p ), which leads to a narrower dispersity in the product. Lowering the temperature to −25 °C further extends the active-chain lifetime. This strategy is also effective for other low-reactivity styrene monomers, including p -chlorostyrene ( p ClSt) and p -chloromethylstyrene ( p CMSt), and is even applicable to the relatively more reactive p -methylstyrene ( p MeSt), offering a versatile metal-free route to the synthesis of styrenic polymers with a narrow dispersity.

High-quality black tea is globally prized for its characteristic aromas, notably “floral” and “sweet” notes. The tea cultivar serves as the genetic foundation for the development of these signature scents. Therefore, precise identification of key odorants across different aroma types is scientifically essential to guide the targeted breeding of superior aromatic tea cultivars. In this study, two widely cultivated national tea cultivars—“Jinmudan” (JMD) and “Fuding Dabaicha” (FDDB)—along with a distinctive national cultivar, “Zhongcha 102” (ZC102), derived from the Longjing population, were consistently processed into black tea. Sensory evaluation combined with quantitative descriptive analysis revealed that JMD exhibited pronounced “floral” and “fruity” notes, whereas ZC102 and FDDB displayed a “high and sweet” aroma profile. Systematic sensomics analysis identified 78 odorants across the three black teas and highlighted several key aroma enhancers: linalool and cis -3-hexenyl butyrate were found to intensify the “floral” attribute; 2-phenyl-2-butenal and geraniol contributed significantly to the “sweet” scent; and 2-ethyl-3,5-dimethylpyrazine was a key contributor to the more pronounced “roasted” note of ZC102 black tea. Molecular docking suggested that trans - β -damascenone, 2-phenyl-2-butenal, and trans - β -ionone may exhibit broad affinity for multiple olfactory receptors, with binding energies as low as −8.1 kcal/mol. Furthermore, linalool, cis -3-hexenyl butyrate, and 2-ethyl-3,5-dimethylpyrazine were found to bind most stably with OR1A1, OR8D1, and OR1A1, respectively. The activation of olfactory receptors was primarily predicted to be governed by hydrogen bonds, with hydrophobic interactions (e.g., Pi-Pi stacking, Pi-sulfur) also possibly playing important roles. This study provides a theoretical basis for precise aroma regulation in black tea through targeted cultivar selection and processing.

H 2 O and SO 2 poisoning of cerium-manganese oxide catalysts remains a critical challenge for low-temperature selective catalytic reduction of nitrogen oxides by NH 3 . Here we show that Ti doping of CeO 2 induces lattice contraction and structural distortion, promoting the generation of oxygen vacancies, active oxygen species, and stable Ce-O-Ti interfaces. These strain-engineered structural modifications enhances surface Lewis acidity and triggers a downshift of the d-band center, collectively improving low-temperature catalytic activity and resistance to H 2 O/SO 2 poisoning. The optimized Ce 8 MnTi 2.5 O x catalyst achieves over 90% nitrogen oxides removal across a 150–335 °C temperature range. Under 5 vol.% water and 100 ppm SO 2 , it maintains over 98% efficiency for 12 h at 210 °C. Furthermore, during stepwise heating from 150 °C to 240 °C with 5 vol.% H 2 O and 200 ppm SO 2 , initial activity suppression below 180 °C is fully reversed at or above 210 °C, demonstrating temperature-driven regeneration. This study introduces a strain-engineering strategy for designing robust catalysts for low-temperature nitrogen oxides removal.
