Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5-wt% NaCl solution. The inhibitor was synthesized by first reacting chitosan (CS) with glucose (GL) via a Schiff base reaction between the amino group of CS and the aldehyde group of GL, followed by the incorporation of hydroxylated boron nitride (OH-BN). Electrochemical measurements demonstrated an inhibition efficiency of 89.8% at 200 ppm after 72 h immersion, which was markedly higher than those of pure CS (64.3%) and the CS–GL intermediate (75.8%). The water contact angle on the steel substrate increased to 91.1°, indicating enhanced hydrophobicity, while the surface roughness was reduced to 0.694 μm (compared with 5.318 μm for bare steel). These combined surface modifications effectively hindered the penetration of corrosive agents. Molecular modeling studies further revealed that the N/O heteroatoms contributed to strong adsorption, thereby significantly blocking the access of corrosive species. This work presents a synergistic strategy in which CS is functionalized with a long-chain molecule (GL) and integrated with BN to form a hybrid corrosion inhibitor that exhibits high efficiency and improved sustainability.

The core–shell FeNPs@Pt shows excellent catalytic activity and stability. • Selective detection via thiol–Michael addition without enzymes or aptamers. • The color development is rapid and convenient, taking only 150 s to complete. • The suppression–recovery mechanism amplifies the signal and enhances sensitivity. In this study, we propose an innovative Acrylamide (AA) detection platform based on platinum-coated magnetic iron nanoparticles (FeNPs@Pt). The introduction of a platinum shell not only preserves the intrinsic catalytic properties of FeNPs but also significantly enhances their structural stability and catalytic activity. Compared with traditional antibody–aptamer-based detection methods, this platform employs a thiol–Michael addition reaction combined with a nanocatalyst-mediated cascade colorimetric process. This approach overcomes key limitations of antibody–aptamer technologies, such as high cost and operational complexity, enabling rapid and low-cost detection of AA. The mechanism involves a specific Michael addition reaction between AA and 2,2′-(ethylenedioxy)diethanethiol (EDT), which mitigates the inhibitory effect of EDT on the catalytic activity of FeNPs@Pt. Subsequently, the addition of 3,3′-dimethylbenzidine (TMB) triggers a colorimetric reaction within 150 s, rendering the result visible to the naked eye. This sensing platform exhibits a linear response over the range of 1–200 μM, with a detection limit as low as 0.63 μM. Notably, the FeNPs@Pt–EDT–TMB-based colorimetric detection platform not only provides an efficient and low-cost method for acrylamide detection but also offers an innovative solution for on-site food safety monitoring, demonstrating significant application potential.

Under the catalysis of MnO 2 , TBHQ can react with Cys to generate fluorescent CDs. • A fluorescence turn-on sensor for detection of TBHQ is proposed based on in-situ formation of fluorescent CDs. • This sensor is capable of quantitatively measuring the concentration of TBHQ in edible oils. Excessive intake of the food additive tert -butylhydroquinone (TBHQ) causes potential hazards to the human body. Designing an easy-to-fabricate and efficient TBHQ sensor is of great research significance. We found that in the presence of MnO 2 , TBHQ can react with cysteine (Cys) to generate fluorescent carbon dots (CDs). Inspired by this simple fluorogenic reaction, a turn-on sensor for TBHQ detection is proposed based on in-situ formation of fluorescent CDs. The sensor offers a linear range of 1–200 μM and a detection limit as low as 0.06 μM. Due to its simple reaction precursors and unambiguous reaction mechanism, this sensor demonstrates good practicability for TBHQ measurement in edible oils. This fluorescence turn-on in-situ sensor, which does not require pre-synthesized materials, offers considerable potential for on-site detection of TBHQ.

The separation of hexane isomers from light naphtha is critical to advancing energy-efficient refining and supporting environmental sustainability. However, this application requires membranes capable of precise molecular discrimination. In this work, we focus on hard acid–hard base coordinated Al-/Zr-MOFs due to their exceptional stability and tunable pore environments. Through combined thermodynamic and kinetic evaluations, four Al-MOFs (KMF-1, CAU-23, MIL-160, Al-bttotb) and Zr-MOF(UiO-66) emerged as promising candidates. UiO-66 was ultimately identified as the optimal platform due to its excellent membrane compactness and techno-economic potential. We subsequently employed a mixed-linker strategy to achieve Ångstrom-level pore size engineering in UiO-66, the resulting UiO-66-NH 2 membrane exhibited superior discrimination between linear/mono-branched (n-hexane, 3-methylpentane) and di-branched (2,2-dimethylbutane) isomers, achieving an ideal selectivity of 4.8—a performance that exceeds most current state-of-the-art MOF membranes. Pervaporation experiments with a simulated C 5 –C 6 naphtha mixture further confirmed the ability of the membrane to efficiently enrich ethylene cracking precursors, while the retentate effectively concentrated high-octane gasoline additives. These results underscore the strong industrial potential of Ångstrom-precision engineered MOF membranes for simultaneous production of high-value chemical feedstocks and premium fuel components from light naphtha.

Carbon fabric (CF)-reinforced polymer composites show great potential in wet friction applications, but their performance is severely limited by poor interfacial adhesion and susceptibility to abrasive wear. Herein, we propose a “rigid-flexible” hierarchical interface strategy utilizing a conformal defect-filling carboxymethyl cellulose (CMC) layer and an in-situ grown rigid UiO66-NH 2 octahedral array to enhance the mechanical and tribological properties of CF/phenolic composites. The CMC/UiO66-NH2 hierarchical modification reduced surface defects and increased the apparent single-fiber tensile strength by 89.3%. Meanwhile, the UiO66-NH 2 array increased the surface roughness and promoted mechanical interlocking with the resin matrix. The combined CMC/UiO66-NH 2 interface improved interfacial load transfer and reduced premature debonding, leading to a 75.1% increase in tensile strength. Furthermore, under alternating friction shear, the hierarchical interface promotes the formation of a protective tribofilm, promoting the in-situ formation of a continuous solid tribofilm. This transitions the wear mechanism from severe abrasive wear to mild sliding wear, resulting in an 81.1% reduction in the specific wear rate. This study provides an interfacial design strategy for designing high-load-bearing and highly durable fabric composites for demanding tribological applications.

In this study, Sm-doped HfO 2 (Hf 1- x Sm x O 2 ) thin films on Pt/TiN/SiO 2 /Si substrates were fabricated using chemical solution deposition (CSD) method. The effects of Sm doping concentration on the microstructure and ferroelectric properties of Hf 1- x Sm x O 2 films were systematically investigated. Grazing-incidence X-ray diffraction (GIXRD) analysis and ferroelectric property measurements of the polycrystalline Sm:HfO 2 films with thicknesses ranging from 60 to 88 nm, revealed that samples doped with 2.50% Sm exhibited optimal ferroelectric characteristics with a residual polarization ( P r ) of 15.96 µC/cm 2 and a coercive field ( E c ) of 1.13 MV/cm after annealing at 800℃. Interestingly, the 2.50% Sm-doped sample also demonstrates excellent endurance and retention properties, sustaining over 10 8 switching cycles without breakdown. Furthermore, density functional theory (DFT) calculations were conducted to elucidate the regulation mechanism of doping samarium on the ferroelectric properties of HfO 2 films. The well consistency of the computational results and experimental observations, indicating that samarium doping is a feasible strategy for enhancing the ferroelectric properties of hafnium oxide films.

A MIP/AuNPs/GCE electrode was constructed for simultaneous detection of CAP and MNZ. • The sensor shows a wide linear range (50–1500 μM) and low LODs of 1.70 and 2.09 μM. • Wavelet transform expands the feature dimensions of the DPV signals to enhance model prediction accuracy. • TPE-optimized XGBoost realizes accurate and robust dual-analyte concentration prediction. • The method achieves satisfactory recoveries in milk, fish, and egg real samples. Food safety concerns have increased the demand for reliable simultaneous detection of chloramphenicol (CAP) and metronidazole (MNZ), as these antibiotics are strictly regulated due to their potential health risks. However, the presence of aromatic nitro groups in both compounds poses a challenge for their simultaneous detection. In this study, an electrochemical sensor integrating electrodeposited gold nanoparticles (AuNPs) with a dual-template molecularly imprinted polymer (MIP) film was developed to achieve selective recognition and signal enhancement for both analytes. However, competitive adsorption at active sites in multi-component systems leads to nonlinear signal responses, rendering traditional linear calibration ineffective. To overcome this limitation, differential pulse voltammetry (DPV) signals were transformed into two-dimensional wavelet spectrograms, from which quantitative image features were extracted, and the necessity and robustness of these features were verified using SHAP analysis. An XGBoost regression model optimized via a Tree-structured Parzen Estimator (TPE) was subsequently constructed, yielding significantly improved predictive performance. The sensor exhibited a wide linear range for both CAP and MNZ (50–1500 μM) and low detection limits (1.70 μM and 2.09 μM, respectively). Satisfactory recoveries (89.37–107.31%) were obtained in spiked milk and fish samples. The proposed TPE-XGBoost-assisted dual-template molecular sensor provides a robust and generalizable strategy for rapid and accurate multi-residue detection in complex food matrices.

Fucoidan (GKP) alleviates OVX-induced bone loss by suppressing osteoclastogenesis. • GKP improves systemic metabolism and identifies betaine as a key metabolite effector. • Betaine attenuates osteoclastogenesis by regulating the OPG/RANK/RANKL signaling. Postmenopausal osteoporosis (PMOP), characterized by excessive bone resorption and impaired bone remodeling, remains a significant global health challenge. This study investigated the protective effects of fucoidan from giant kelp (GKP) against PMOP and its underlying mechanisms in ovariectomized mice. GKP supplementation attenuated bone loss by preserving trabecular microarchitecture, normalizing systemic mineral homeostasis, and suppressing osteoclastogenesis, as evidenced by the downregulation of osteoclast-related genes. 16S rRNA gene sequencing revealed that GKP reshaped the gut microbiota by decreasing the Bacteroidota/Firmicutes ratio and enriching beneficial taxa, which promoted short-chain fatty acid production. Targeted metabolomics revealed that GKP induced profound systemic metabolic reprogramming, particularly amino acid metabolism, and identified betaine as a key systemic metabolite effector upregulated following GKP treatment. In vitro assays demonstrated that betaine suppressed receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation and mitigated inflammation. In vivo validation demonstrated that betaine intervention recapitulated the osteoprotective phenotype observed in GKP-treated mice, which was associated with regulation of the osteoprotegerin/RANKL/RANK signaling axis. These results indicate that GKP exerts anti-osteoporotic effects in association with changes in gut microbiota and systemic metabolism, while betaine-mediated regulation of the OPG/RANKL/RANK signaling may contribute to its osteoprotective activity.

Mixed-matrix membranes (MMMs) offer a promising route to efficient gas separation by synergizing the superior transport properties and stability of porous fillers with the scalability of polymeric matrix. However, fabricating ultrathin, high-loading MMMs remains a significant challenge, as conventional solution processing inevitably leads to filler agglomeration. Here, we report a decoupled assembly strategy to fabricate ultrathin, highly loaded MMMs by separating membrane formation into two distinct stages: filler monolayer assembly and subsequent matrix electropolymerization. This approach enables the formation of ordered, close-packed nanoparticle monolayers, facilitating the attainment of ultra-high filler loadings (>60 wt%) in the final membrane. Using metal-organic frameworks (MOF-801 and MOF-808) as fillers and a conjugated microporous polymer (CMP) as the matrix, we constructed robust MMMs with thicknesses of 390 nm and 550 nm, respectively. Applied to CO 2 /CH 4 separation, the resulting membranes exhibited a 12-fold increase in CO 2 permeance (from 26 to 313 GPU) and a 120% enhancement in selectivity compared to the pristine polymer matrix.

Metal-deficient Zr nodes are constructed in UiO-66-NH 2 by vacuum treatment. • Zr-node microenvironment regulation enhances charge separation and O 2 activation. • UN 200/28 achieves 272.9 μmol g −1 h −1 H 2 O 2 production in pure water. • UN 200/28 delivers a 20-fold activity increase and 6.36% AQY at 420 nm. • H 2 O 2 formation follows an ORR-dominated pathway with secondary WOR contribution. Photocatalytic H 2 O 2 production from pure water and O 2 offers a sustainable route for green oxidant synthesis, yet its efficiency is limited by insufficient O 2 activation, sluggish charge separation, and poorly defined active sites. Herein, a metal-defect-engineered UiO-66-NH 2 photocatalyst is constructed through high-temperature vacuum treatment to regulate the Zr-node coordination microenvironment. The optimized UN 200/28 preserves the UiO-66-NH 2 crystalline framework and octahedral morphology, while a 7.8% decrease in Zr content is confirmed by ICP, STEM, FTIR, XPS and EPR, thereby indicating the formation of metal-deficient Zr nodes and the reconstruction of the local Zr O coordination microenvironment. These defect-induced structural modifications broaden visible-light absorption, narrow the band gap from 2.88 to 2.57 eV, and promote photogenerated charge separation and transfer. UN 200/28 exhibits markedly enhanced photocatalytic H 2 O 2 production in pure water under O 2 , achieving an H 2 O 2 formation rate of 272.9 μmol g −1 h −1 , a 20-fold improvement over pristine UiO-66-NH 2 , and an apparent quantum yield of 6.36% at 420 nm. The O 2 reduction and water oxidation processes account for approximately 63.2% and 36.8% of the total H 2 O 2 formation, respectively. This work demonstrates that cluster-level regulation of the Zr-node coordination microenvironment is an effective strategy for enhancing photocatalytic H 2 O 2 production in pure water.

A novel imidazole-functionalized COF (TPT-DB-COF) was constructed. • TPT-DB-COF showed good adsorption performance for neonicotinoid insecticides. • The adsorption mechanisms involve hydrogen bond, π-π interaction, and pore filling. • This method effectively detected neonicotinoid insecticides in four real samples. Developing an effective method for reliable monitoring of insecticide residues is desirable for public health. This study developed a rapid and sensitive method to determine neonicotinoid insecticides (NEONICs) in water, lemon beverage, wax gourd, and tomato samples. An imidazole-functionalized COF (TPT-DB-COF) featuring a spherical core-shell structure was developed and used as a solid-phase extraction (SPE) adsorbent. The TPT-DB-COF exhibited superior adsorption ability for NEONICs. The TPT-DB-COF-SPE/HPLC-DAD approach for trace analysis of NEONICs had low detection limits (0.02–0.03 ng mL −1 for water samples, 0.07–0.08 ng mL −1 for lemon beverage, 0.6–0.8 ng g −1 for wax gourd samples, and 0.9–1.3 ng g −1 for tomato samples), high trueness (method recoveries of 87.0% - 114%), and acceptable precision (relative standard deviations below 7.9%). Such good performance parameters pave the way for the application of TPT-DB-COF in the analysis of NEONICs. Download: Download high-res image (197KB) Download: Download full-size image

This work focuses on the development of a paraffin-based shape stabilization phase change composite containing chitosan@polypyrrole aerogel as a skeleton carrier for low temperature thermal energy storage and efficient photothermal conversion. Such a composite is fabricated by incorporating the three-dimensional network aerogel, that synthesized through the deposition of polypyrrole on the pores of chitosan using the in situ oxidation and polymerization processes. Characterization results indicate that polypyrrole and chitosan are bonded via hydrogen bridges, forming a rigid and open-celled network structure that is able to accommodate the liquid paraffin with a mass ratio as high as 93.25%. At such a composition, the composite achieves a melting temperature of 36.86 °C and a latent heat of 194.95 J/g. The doping of polypyrrole largely improves the composite thermal stability and thermal conductivity. In comparison with the pure paraffin, the thermal decomposition temperature and thermal conductivity of the composite containing 9.66 wt% chitosan@polypyrrole aerogel are respectively enhanced by 33.7% and 3.26 times. Splendid thermal cycling performance is also achieved in the composite. After 300 repeated heat-cold cycles, the paraffin concentration is only decreased by 4.35%, and no apparent leakage or deformation is observed in the composite. Photothermal conversion tests reveal that polypyrrole endows the composite with highly efficient broadband light absorption capabilities. Under simulated sunlight irradiation of 100 mW/cm 2 , the heating rate of the composite can reach 33.74 °C/h, and the photothermal conversion efficiency is up to 73.22%.
