As emerging environmental contaminants with suspected human health impacts, benzotriazole ultraviolet stabilizers (BUVSs) lack empirical evidence regarding pulmonary carcinogenicity in exposed populations, highlighting the need to investigate their potential association with lung cancer. This study aimed to analyze the relationship between urinary BUVSs concentrations and lung cancer risk within the general population of Hangzhou, China. This case-control study included 397 newly diagnosed lung cancer patients and an equivalent cohort of age- and sex-matched healthy controls. Urine samples were analyzed for five different types of BUVSs, with total concentrations ranging from 0.46 to 36.40 μg/g creatinine. 2-(2’-Hydroxy-3’,5’-di-tert-butylphenyl)-5-chloro-benzotriazole (UV-327) was the most prevalent, with a mean concentration of 5.09 μg/g creatinine. Logistic regression models were employed to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for assessing lung cancer risk in relation to urinary BUVSs concentrations. Following adjustment for covariates including sex, smoking status, alcohol intake, and dietary habits, urinary 2-(2H-benzotriazol-2-yl)- p -cresol (UV-P) was the only BUVS demonstrating a significant correlation with lung cancer risk. Participants in the highest urinary UV-P concentration group exhibited a 4.5-fold higher risk of lung cancer relative to those in the lowest group (adjusted OR=4.55, 95% CI:2.84–7.28, p for trend < 0.01). The link between elevated UV-P exposure and a higher risk of lung cancer was affected by factors such as smoking status and dietary habits. These findings provide novel evidence of a potential association between BUVSs exposure—particularly UV-P—and lung cancer in the general Chinese population, and highlight the need for future longitudinal and mechanistic studies to confirm these associations and elucidate the underlying biological pathways.

The low water-to-cement ratio cement-based materials represented by high-performance or ultra-high-performance concrete exhibit excellent mechanical and durability properties but suffer from poor flowability and insufficient and nonuniform hydration. Polyethylene glycol-grafted cellulose nanocrystal (PCNC) was synthesized by grafting polyethylene glycol (PEG) onto cellulose nanocrystal (CNC) and then was incorporated into cement paste to improve its flowability and hydration performance. A series of tests were conducted to analyze the flowability, compressive strength, and hydration behavior of cement paste with PCNC, with the hydration mechanism revealed. The results show that PCNC promotes more complete and uniform cement hydration through mechanisms including short-circuit diffusion, nucleation, and steric hindrance, resulting in improved flowability and compressive strength compared to pure and CNC-modified cement paste. The optimal PCNC dosage is 0.1 %, where the flowability and 28-day compressive strength increased by 10.73 % and 30.63 %, respectively. Finally, a mechanism model by which PCNC improves cement hydration was proposed.

During their 120-day circulatory lifespan, red blood cells (RBCs) undergo repeated mechanical deformation as they traverse microcapillaries and splenic inter-endothelial slits (IES). This cyclic mechanical loading gradually impairs RBC deformability, ultimately leading to their clearance by the spleen. However, current platforms for investigating RBC fatigue often couple mechanical loading with real-time observation, which obscures the cumulative impact of cyclic strain. To address this limitation, we developed an integrated microfluidic chip equipped with a dedicated "S"-shaped fatigue zone-each RBC experiences hundreds of extrusion events during a single continuous pass through this zone-followed by a physically decoupled observation zone. This design enables clear separation of fatigue induction from biomechanical evaluation. Our findings show that cyclic extrusion drives a progressive morphological transition in the RBC population from discocytes to echinocytes and spherocytes, along with reduced cell volume and surface area, increased membrane shear modulus, and elevated sphericity. Combined experiments and simulations reveal that the passage of spherocytes depends not only on their deformability but also critically on the relative size of the cells versus the channel dimensions. Furthermore, simulations of splenic filtration identify the sphericity index-not membrane stiffness-as the primary geometric factor governing RBC retention in IES. This work presents a high-throughput, label-free platform that disentangles RBC fatigue induction from post-fatigue analysis. It provides mechanistic insights into how repetitive mechanical stress regulates RBC aging and clearance, offering a valuable tool for advancing our understanding of RBC physiology in health and disease.

In the face of increasingly complex electromagnetic (EM) pollution, heterogeneous interface engineering is an effective strategy to promote EM response. The enrichment of heterogeneous interfaces can be achieved by constructing hierarchical hollow structures. In this study, waxberry-like hierarchical hollow carbon nanospheres (HHMC) embedded with ultrafine Mo 2 C nanoparticles (NPs) are synthesized by carbonization of phenolic resin microspheres using ammonium molybdate as a molybdenum source and SiO 2 as a pore-forming agent. Among them, the good dispersion of Mo 2 C NPs forms a large number of nanoscale heterogeneous interfaces, which strengthens the polarization relaxation process. Concurrently, the hierarchical hollow structure optimizes the impedance matching with the air medium. Thanks to these properties, the prepared HHMCs exhibit remarkable EM attenuation capacity with a minimum reflection loss (RL) of -59.6 dB and an effective absorption bandwidth (EAB) up to 4.8 GHz. Furthermore, macroscopic three-dimensional (3D) metasurface simulations reveal its ultra-broadband absorption characteristics, which extend from 10.4 GHz (7.6-18 GHz) to 14.1 GHz (3.9-18 GHz) as the thickness increases from 1.4 mm to 3 mm. This result provides fundamental guidance for efficient EM energy attenuation through heterogeneous interface engineering.

Metal nanoclusters (NCs) are attracting increasing attention for their molecule-like photoluminescence (PL) properties, while achieving emission tuning remains a challenge. Here, we report the solvation-triggered isomerization of surface terminations and modulation of electron transfer dynamics in the 6-mercaptopurine-9-β-D-ribofuranoside (6-MPR)-protected gold NCs, to attain a controllable emission spanning widely from 495 nm sky-blue to 800 nm near-infrared light. Specifically, the isomerization of 6-MPR gives Au(I)-thione isomer terminals (i.e., R 1 domain) and Au(I)-thiol isomer terminals (i.e., R 2 domain), confers the gold NCs with two prominent emission bands at 590 nm (i.e., PL I from the electron transfer emission state) and 770 nm (i.e., PL II from the triplet state), respectively. The further solvation of gold NCs is rationally designed by mapping out fourteen different organic solvents into four categories referring to their inherent properties of viscosity, polarity, coordination ability, and the strength of proton-giving capacity. This allows for rational conversion between R 1 and R 2 domains, and is concurrent with modulation of the proton-coupled electron transfer dynamics and thus customizable emission tuning.

Reliable detection of volatile organic compounds (VOCs), such as acetone, is essential for environmental monitoring and non-invasive disease diagnosis. However, conventional In 2 O 3 -based gas sensors suffer from high operating temperatures, humidity interference, and limited selectivity. Herein, we report one-dimensional (1D) hollow In 2 O 3 @Fe 2 O 3 core-shell heterojunction tubes fabricated via a tannic acid (TA)-assisted transformation of MIL-68(In). TA plays dual roles in etching the MIL-68(In) template and coordinating with Fe 3 + ions to form a mesoporous tubular structure with an enhanced specific surface area of 89.57 m 2 g −1 for In 2 O 3 @Fe 2 O 3 -0.75. Benefiting from the synergistic n-n heterojunction effect and abundant active sites, the optimized In 2 O 3 @Fe 2 O 3 -0.75 sensor exhibits a markedly improved response of 263.6 towards 100 ppm acetone at 200 °C, approximately 3.6 times that of pristine In 2 O 3 , and enables detection down to 100 ppb with a response of 1.87. Furthermore, the sensor demonstrates rapid response/recovery (8/9 s), excellent long-term stability over 30 days, and remarkable humidity tolerance across 29–82% RH at 25 °C. This work provides an effective MOF-derived strategy for constructing hollow metal-oxide core-shell heterojunctions toward high-performance and humidity-tolerant gas sensing applications.

Inspired by bionic surface design principles, this study developed a one-step method to deposit thiol-isocyanate polymer microspheres on dopamine-treated carbon fiber surfaces, creating a raspberry-like surface architecture. The bioinspired structure serves as both physical and chemical “bridges” between carbon fibers and epoxy resin, while simultaneously enhancing the chemical activity, mechanical interlocking effect, and wettability of the fiber surfaces. Compared to untreated samples, the modified composites exhibited 63.11% improvement in interlaminar fracture toughness, with impact strength and tensile strength increasing remarkably by 167.55% and 73.59%, respectively. Furthermore, systematic investigation of the interfacial reinforcement mechanisms and energy dissipation modes was conducted through comprehensive fracture morphology analysis.

This study addresses antibiotic water pollution by synthesizing Zr-doped Bi₂₄O₃₁Cl₁₀ (Bi₂₄(₁₋ₓ)Zr₁₈ₓO₃₁Cl₁₀) photocatalysts via hydrothermal method for tetracycline hydrochloride (TC-HCl) removal. Zr doping ratios (6–14%) were systematically investigated, with the optimal BZOC4 (12% Zr) degrading 91.24% of 20 mg/L TC-HCl within 120 min under 500 W xenon lamp irradiation (pH = 9). Its reaction rate constant (0.0239 min −1 ) is triple that of pristine Bi₂₄O₃₁Cl₁₀. Zr doping reduces the band gap from 3.12 eV to 2.8 eV, improves visible light utilization (absorption edge red-shifted to 525 nm), accelerates electron transfer, and reduces e − /h + recombination—supported by UV –Vis DRS, PL, and electrochemical tests. Superoxide radicals (O₂ − ·) and holes (h + ) are primary active species, confirmed by radical trapping and ESR. TOC analysis confirms 32.4% mineralization of TC-HCl to CO₂ and H₂O.This work offers new design strategies for bismuth halide-based photocatalysts in antibiotic remediation by integrating structural regulation and electronic modulation via Zr doping.

Enrichment and leaching of aluminum (Al), lithium (Li) and gallium (Ga) from coal fly ash is an important step in the recovery of critical elements, which determines the dissolution of critical elements in the aqueous phase and influences subsequent extraction efficiency. In this work, synergistic recovery of Al, Li and Ga was investigated by a combination of physical enrichment and Na 2 CO 3 fusion-citric acid leaching processes. The results show that fly ash from different regions of Pingwei Power Plant in China, designated as FA-PA and FA-PB respectively, exhibits high consistency in chemical composition and mineralogy. Both batches exhibited enrichment of Al, Li, and Ga in particles < 45 μm in diameter. Calcination at 870 °C for 90 min with Na 2 CO 3 effectively activated Al, Li, and Ga in both samples. However, the optimal leaching conditions for Al, Li, and Ga differed slightly between the two batches. FA-PA achieved maximum leaching rates of 97.1%, 98.9%, and 80.4% for Al, Li, and Ga respectively, while FA-PB exhibited leaching rates exceeding 90% for all three elements under optimal conditions. The sodium carbonate fusion combined with citric acid leaching employed in this study effectively disrupted the silicate-aluminate glass of fly ash and activated the reactive substances within the minerals, enabling the release of Al, Li, and Ga into solution. This study provides theoretical support for the synergistic recovery of Al, Li and Ga from coal fly ash.

Bis(2-ethylhexyl) phosphate (HDEHP) was introduced as a novel collector for the flotation separation of cassiterite from quartz. Under the optimized flotation conditions (pH 8.0±0.2, HDEHP concentration of 15.0×10 -5 mol/L), a cassiterite concentrate assaying 74.01% SnO 2 was obtained with a recovery of 94.63%, demonstrating excellent separation performance. Compared with benzohydroxamic acid (BHA), HDEHP exhibited superior selectivity over a broader pH range. The adsorption mechanism was systematically investigated through contact angle measurements, zeta potential analysis, FTIR, XPS, ToF‑SIMS, AFM, and DFT calculations. The results indicate that HDEHP chemisorbs onto the cassiterite surface primarily via its PO(OH) groups, which coordinate with surface Sn sites to form a stable hydrophobic layer. In contrast, its interaction with quartz remained weak. DFT simulations further revealed that electron transfer and orbital hybridization occur between the oxygen atoms of HDEHP and surface Sn atoms, leading to stable chemical bonding and enhanced adsorption. Consequently, due to its strong and selective adsorption on cassiterite, HDEHP serves as an effective collector for the flotation separation of cassiterite from quartz.

Loss of toughness in titanium matrix composites (TMCs) is often inevitable, as strength enhancement typically comes at the expense of ductility, especially for brittle ceramic reinforcements induced by interfacial chemical reaction. To fully exploit the strengthening potential of nanocarbons in TMCs and maintain ductility, it is critical to mitigate the in-situ reactions between nanocarbons and titanium. This study proposes an inspired strategy by reinforcing Ti–6Al–4V (Ti64) matrix with graphene oxide (GO) decorated with Fe 3 O 4 nanocrystals (Fe 3 O 4 @GO/Ti64). This design achieves 41.6% improvement in toughness, with simultaneously enhanced strength and elongation, compared to that of Ti64 alloy. Uniform Fe 3 O 4 coatings ( ∼ 20 nm) were distributed on the GO surface and subsequently consumed during consolidation via reaction with the Ti matrix, thereby preserving GO. Microstructural analysis of plastic deformation revealed that elongation was primarily attributed to the dislocation slip bands, grain boundary sliding and twins, while the in-situ TiC inhibited slip-band motion. The estimated strengthening factors illustrated that solid-solution strengthening dominated the enhanced strength in all composites. Furthermore, the Fe 3 O 4 @GO/Ti64 composites exhibited significantly enhanced load transfer effects compared with GO/Ti64, due to the Fe 3 O 4 modificative coatings. These findings underscore the crucial role of interfacial decoration and solid-solution mechanisms in improving the overall mechanical performance of the TMCs, while also highlighting their economic and environmental potential in lightweight metallic design.

Accurate qualitative and quantitative determination of free radicals during lipid oxidation, which is the core process of edible oil quality deterioration and essentially a free radical chain reaction, is of crucial importance. To overcome this problem, we developed and validated an analytical method for the specific characterization of key radicals in lipid oxidation. These radicals (R•, RO•, and ROO•) were trapped using N-tert -butyl-α-phenylnitrone under iron-mediated conditions, leading to the formation of stable adducts that were subsequently analyzed by LC–MS/MS–IT–TOF. This method offers good sensitivity with low limits of detection (0.06–0.15 µM) and limits of quantification (0.20–0.50 µM). Density functional theory calculations further confirm that the reaction proceeds readily and yields thermodynamically stable products. When applied to the methyl linoleate oxidation system, the method demonstrated that methyl linoleate alkyl radical (L•) predominated during oxidation, with its concentration peaking at 3.74 × 10 −2 mM (accounting for up to 70% of radicals) at 4 h followed by a decline due to chain termination reactions, whereas methyl linoleate peroxyl radicals (LOO•) concentration stabilized as oxidation progressed (1.46 × 10 −2 mM, 27% of radicals), and methyl linoleate alkoxyl radicals (LO•) remained at a consistently low concentration (1.58 × 10 −3 mM) owing to its preferential conversion via the β-scission pathway. These results were consistent with electron spin resonance (ESR) data, thereby validating the method's reliability. Consequently, this method enables the precise monitoring of lipid oxidation processes, serving as a valuable tool for assessing antioxidant efficacy in lipid science. Practical Applications : We present an analytical method integrating N-tert -butyl-α-phenylnitrone (PBN)-based spin trapping with LC–MS/MS–IT–TOF for direct tracking of key lipid radicals (L•, LO•, and LOO•) throughout the lipid oxidation process. This method addresses a long-standing technical gap in lipid oxidation research, providing a robust, practical tool for both high-throughput screening of high-efficacy antioxidants and rational design of stable lipid-containing food formulations. By bridging fundamental analysis and product development, our technique has clear real-world implications for extending the shelf life of lipid-based foods, offering significant value to food chemistry research while delivering substantial economic and sustainability benefits to the global food industry.
