The superior photoreduction of U(VI) under visible light irradiation is one of most attractive way for the sustainable development of nuclear energy, whereas the development of long-term stable, highly photocatalytic performance and low cost photocatalyst remains a challenge owing to the lack of accessible adsorption intensity in the visible light range. Herein, a boron-incorporated triazine-linked 2D covalent organic frameworks with amidoximeylation (B/AO-COF) was fabricated via solvent modulation method. In comparison with COF (0.0049 /min) and AO-COF(0.0102 /min), the large removal rate of B/AO-COF (0.0145 /min) showed the introduction of AO groups accelerated U(VI) removal. The high photocatalytic efficiency (~ 95 % within 1 h) and good stability (< 5 % after 5 recycles) of B/AO-COF under visible light irradiation was attributed to low recombination of photogenerated electron-hole pairs. According to quenching experiments and ESR analysis, photogenerated electrons and superoxide radials played an important role in U(VI) photoreduction. These findings are crucial for the application of B/AO-COF on the highly efficient removal of U(VI) from aqueous solution in actual environmental remediation.

The widespread use of antibiotics, particularly ofloxacin (OFL), has led to their persistent presence in aquatic environments. The acclimation of Tetradesmus obliquus ( T. obliquus ) using OFL was found to enhance both its tolerance and degradation capability. After 14 d of exposure to 1 mg/L OFL, the degradation rate of the acclimated T. obliquus was 25.81% higher than the non-acclimated, mainly due to enhanced bioaccumulation and biodegradation. Physiological and biochemical analyses showed that acclimated T. obliquus experienced significantly less growth inhibition and oxidative stress under OFL exposure than non-acclimated. Transcriptome results show that OFL exposure impacts DNA replication and repair, photosynthesis, membranes, oxidoreductases, and energy metabolism in both non-acclimated and acclimated T. obliquus . Acclimated T. obliquus by adjusting carbon metabolism to boost energy, enhancing antioxidant enzymes, upregulating ABC transporters to expel antibiotics, increasing carotenoid synthesis for photosynthetic protection, and using amino acid synthesis to offset reduced protein production. These adaptations greatly improve the survival and degradation abilities of algae that were acclimated through repeated OFL exposure. Molecular docking and dynamics simulations suggested the possible formation of new complexes between SOD and GST during acclimation. Overall, this study provides valuable insights into the adaptation of algae to antibiotic pollution and highlights the potential of acclimated microalgae for advanced bioremediation strategies.

Magnetoelectrical textiles, as self-power device to generate energy from motions, are promising building blocks for wearable electronic fields, but these traditional strategies towards magnetoelectrical textiles still suffer from insufficient stability and reliability, and the large-scale fabrication of magnetoelectrical textiles still remains challenging. Herein, soft magnetic fiber and its knitted fabric based NdFeB@ZIF-8 composite particles were proposed, and their electro-magnetic response performances were comprehensively characterized. NdFeB@ZIF-8 composite particles were synthesized, and they exhibited excellent magnetic property with the remnant magnetization (Mr) and coercivity (Hc) at 80 emg/g and 8604 Oe, respectively, the Ms. of NdFeB@ZIF-8 particles was 113.5 emu/g. The magnetoelectrical fibers prepared by micro-controlled flow spinning technology exhibited a breaking elongation of 575%. Driven by an external magnetic field, the magnetoelectrical fibers could bend up to 43°, and moved easily in tiny tube and lift a weight of 20 g. Similarly, the magnetoelectrical fabrics can undergo various deformations. Moreover, the magnetoelectric power generation system delivered a continuous and stable output voltage, allowing the generation of a stable electrical signal of 15 mV under various external forces. The maximum output peak power density was 551.25 mW/m2 when the resistance of the external load was 1 Ω. The presence of a magnetic field endowed magnetic fabrics with a certain degree of electromagnetic shielding effectiveness. In sum, this study employed an efficient and environmentally friendly fabricating strategy for magnetoelectrical textiles with self-power ability, showing great potential for the wearable electronics application.

Electronic modulation in quantum-size catalysts plays a critical yet underexplored role in governing the hydrogen evolution reaction (HER) in anion-exchange membrane water electrolyzers (AEMWEs). Here, cobalt nanoparticles with tunable diameters (5–15 nm) encapsulated in nitrogen-doped carbon nanotubes (Co@NCNTs) were engineered to elucidate how size-dependent orbital evolution dictates HER activity in alkaline media. We found that a smaller particle diameter results in a better charge transfer capability. Besides, the in-situ Raman spectroscopy shows that Co@NCNTs with an optimized diameter preserve a stable Co–N–C vibration at 690 cm −1 throughout HER, while transiently forming surface C–OH species—key intermediates that promote water dissociation. Inverse and ultraviolet photoelectron spectroscopy (IPES/UPS) further reveal that the quantum-size-effect splits the d -band and gives rise to a stronger Co 3 d –O 2 p hybridization. This enhanced hybridization facilitates electronic delocalization across Co–N–C/O interfaces, enabling dynamic charge transfer that favors the formation and subsequent reduction of C–OH intermediates during HER. As a result, the optimized Co@NCNTs catalyst achieves an overpotential of only 33 mV at 10 mA cm −2 and delivers 550 h operational stability in a full AEMWE. These findings provide direct experimental evidence that quantum-size-tailored orbital coupling governs interfacial OH/H 2 , thereby linking spectroscopic insight with catalytic function and establishing a rational design principle for high-performance non-noble-metal catalysts.

The gelling properties of pectin depend on its structure. In this work, low methoxy potato pectin (PP) was enzymatically extracted. PP was modified using polygalacturonase (PG) and pectin lyase (PL) to elucidate the relationship between structural characteristics and gelation properties. PG-modified potato pectin (PG-PP) had the lowest molecular weight ( M w ) and homogalacturonan (HG) domain proportion, followed by PL-modified potato pectin (PL-PP) and PP. The gelation behaviors of PP, PG-PP, and PL-PP induced by glucono-δ-lactone (C 6 H 10 O 6 ) and calcium chloride (CaCl 2 ) were evaluated through a multidimensional characterization. The results revealed that the ranking of gel strength and creep recovery properties (C 6 H 10 O 6 -/CaCl 2 -induced PP > PG-PP > PL-PP) mirrored the order of their binding strength with C 6 H 10 O 6 /CaCl 2 in thermodynamic analysis, with CaCl 2 -induced gels exhibiting higher strength than those induced by C 6 H 10 O 6 . In conclusion, while reduced HG content and M w weaken gel strength, the saturation state of pectin's molecular structure exerts a greater impact on gelling properties.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are ubiquitous pharmaceutical contaminants frequently detected in aquatic environments and medicinal products, raising increasing concerns regarding their chronic ecological toxicity and potential human health risks through long-term exposure. However, accurate exposure assessment of NSAIDs is often hindered by their trace-level occurrence and strong matrix interferences in complex samples. To address these analytical challenges, this study created a new polypyrrole-modified cotton fiber via a controlled oxidative polymerization process, leading to the construction of a fiber-supported stick microextraction (FS-SME) device. Owing to the synergistic contribution of π–π interactions, hydrogen bonding, and pseudo‑hydrogen bonding, the sorbent materials exhibited exceptional mechanical stability and a high adsorption capacity toward NSAIDs (up to 45.25 mg/g). Adsorption kinetics and isotherm analyses revealed that the enrichment process was dominated by rapid monolayer chemisorption, ensuring efficient and reproducible extraction. Under optimized conditions, the FS-SME-HPLC method provided satisfactory recoveries (62.6%–75.4%), low detection limits (0.2–2.5 ng/mL), and excellent linearity (R 2 ≥ 0.992) within a 5 mL sample system, while also exhibiting good reusability and batch-to-batch consistency. Overall, this work introduced a new cotton fiber functional material and delivered a reliable device for risk-informed environmental monitoring of NSAIDs in complex matrices, thereby supporting risk management and regulatory decision-making for pharmaceutical contaminants.

Simple SummaryOur study investigated the mechanisms by which Icaritin (ICT) suppresses prostate cancer (PCa) progression via modulation of the gut microbiome. Using C57BL/6 and TRAMP mouse models, we found that a high-fat diet (HFD) significantly reduced in-testinal Akkermansiaceae abundance and vitamin K2 levels relative to control di-et-fed mice. ICT supplementation in HFD-fed TRAMP mice restored Akkermansiaceae pop-ulations and elevated vitamin K2 levels, concurrently decreasing serum leptin and in-creasing adiponectin concentrations. Direct gavage with Akkermansiaceae similarly elevated vitamin K2 levels, improved adipokine profiles, and extended survival. These findings demonstrate that ICT exerts anti-tumor effects by modulating gut Akker-man-siaceae, thereby enhancing vitamin K2 production and regulating adipokine se-cretion, which supports its clinical potential for PCa treatment.Background:High-fat diet (HFD) induced inflammation and tumorigenesis by altering gut microenvironment and gut microbiome profiles. Vitamin K2 along withAkkermansiaceae, an intestinal symbiote, is involved in anti-tumors including prostate cancer (PCa). Although there have been clinical studies of Icaritin (ICT) for anti-tumor, its detailed mechanism for anti-PCa remains unclear. Here, we explored the effect of ICT on PCa progression that involved altering the mouse gut microbiome.Methods:We used 20 C57BL/6 mice and 85 transgenic adenocarcinomas of mouse prostate (TRAMP) mice as animal models. Then, 16SrRNA pyrophosphate gene sequencing was used to analyze the intestinal fecal microbiome of mice in each group. At the same time, vitamin K2 in fecal samples was determined by High Performance Liquid Chromatography (HPLC), and the content of adipokines leptin and adiponectin in serum was determined by Elisa.Results:It was observed that the relative abundance ofAkkermansiaceae(9.14 ± 2.75% (C57BL/6J-N) vs. 5.66 ± 1.35% (C57BL/6J-HFD); 1.21 ± 0.61% (TRAMP-N) vs. 0.67 ± 0.45% (TRAMP-HFD) (p< 0.05) and vitamin K2 (C57BL/6J-HFD was 0.41-fold to C57BL/6J-N, TRAMP-HFD was 0.71-fold to TRAMP-N) in the intestinal fecal of HFD C57BL/6 and TRAMP were significantly lower than those of control mice. Both the ratio ofAkkermansiaceaeand vitamin K2 in the gut fecal were significantly increased in HFD-fed TRAMP mice supplemented with ICT compared with HFD-fed TRAMP group (p< 0.01). When HFD TRAMP mice were fed withAkkermansiaceaeby gavage, the content of vitamin K2 in the intestinal fecal of the mice was increased, the adipokines leptin in the serum were decreased, but the adiponectin was significantly increased, and the overall survival time of the TRAMP mice was significantly prolonged. Our study shows that ICT rescued the reduction inAkkermansiaceaein the gut microbiota of HFD TRAMP mice. ICT suppresses PCa by modulatingAkkermansiaceaein the gut, increasing vitamin K2, and regulating adipokines leptin and adiponectin secretion.Conclusions:Our study suggested that ICT might regulate abundance ofAkkermansiaceaeto increase vitamin K2 to suppress PCa. This provides theoretical basis and data support for the clinical application of ICT in the treatment of PCa.

Baloxavir marboxil (BXM), a novel oral antiviral drug, is classified as BCS II and suffers from bioavailability limitations due to its low solubility. To overcome these limitations, a cocrystallization strategy was adopted in the present study. It is noteworthy that no cocrystal form of BXM has been reported in the CSD database. This study reports the synthesis and comprehensive characterization of a novel baloxavir marboxil and probenecid (PRO) pharmaceutical cocrystal (BXM-PRO), which was designed to improve the dissolution performance of BXM for enhanced therapeutic efficacy. The single crystal was successfully prepared via slow evaporation from a mixed solvent of methanol and water and thoroughly characterized using single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric and differential scanning calorimetry, Fourier transform infrared spectra, scanning electron microscopy, Hirshfeld surface analysis, and density functional theory calculations. Structural analysis confirmed the formation of a cocrystal stabilized by strong O–H···O hydrogen bonds. Subsequent evaluations included the powder dissolution rate, accelerated stability, and antiviral activity. The dissolution profiles revealed that the BXM-PRO cocrystal exhibits a significantly enhanced dissolution rate and higher solubility in both water and pH 6.8 buffer compared to pure BXM. Theoretical analysis suggests that strong hydrogen bonding between hydrogens of the O–H···O complexes plays a critical role in facilitating the improved dissolution performance of the cocrystal. Additionally, cytotoxicity assessment via CCK-8 assay indicated that the cocrystal possesses lower cytotoxicity against MDCK cells than BXM. The antiviral activity of the BXM-PRO cocrystals was compared with that of BXM alone as well as with that of physical mixtures of BXM with PRO in adequate stoichiometric ratios. Antiviral assays demonstrated that the cocrystal exhibits superior efficacy against the Yamagata strain, reduced effectiveness against H1N1 PR8 and H3N2 strains, and comparable activity against the Victoria strain relative to BXM alone. These findings indicate that the BXM-PRO cocrystal represents a promising strategy to enhance the solubility and bioavailability of BXM, with potential clinical benefits for the treatment of influenza virus infections.

Thermally rearranged (TR) polymers have emerged as promising candidates for gas separation membranes but often suffer from poor resistance to CO2-induced plasticization. In this study, rigid biphenyl (TMB) units were introduced into the polyimide backbone, and bromine atoms were incorporated into the polymer side chains to enable controlled cross-linking. The polymers underwent in situ debromination during thermal rearrangement, transforming into cross-linked PBO networks to enhance both permeability and selectivity. The optimized 50%-Br-6FTA-PBO(1:1) membrane exceeded the 2008 Robeson upper bounds for CO2/CH4 and H2/CH4 separations, as well as the 2018 upper bound for CO2/CH4 mixed gas separation. Moreover, the cross-linked network structure conferred excellent antiplasticization performance under CO2 pressures up to 600 psi and maintained stable gas separation properties over 1000 h of aging. This work provides a universal strategy for designing TR membranes that possess high permeability, high selectivity, excellent anti-CO2 plasticization performance, and long-term stability.

The development of biomass-derived fuels presents a promising solution for mitigating the severe carbon emissions associated with fossil fuels. A key strategy involves the direct refining of aqueous-phase bioethanol into higher alcohols, which serves as key precursors for diesel blendstocks and biojet fuel. Herein, to enable the direct upgrading of aqueous ethanol, we developed carbon-encapsulated Ni nanocatalysts (Ni@C) with water resistance by pyrolyzing organic precursors under acid–base regulation. The catalytic coupling yields 46.5 C-mol % of higher alcohols, of which C4–C7 and C8–C16 alcohols constitutes 56.9% and 35.2% in product selectivity, respectively. Excellent miscibility with diesel is exhibited by C4–C7 alcohols across a wide range of blending ratios. Furthermore, hydrodeoxygenation of C8–C16 alcohols provides a direct route to biojet fuel. Results from experiment and characterization demonstrate that acid–base regulation effectively tunes the local electronic structure and carbon defects on the Ni@C nanocatalyst surface. The proposed approach allows for precise modulation of the dehydrogenation, aldol condensation, and hydrogenation steps in the Guerbet reaction pathway, which suppress carbon chain scission and enhance the yield of higher alcohols. Overall, this research offers a novel and feasible strategy to the sustainable synthesis of higher alcohols from bioethanol, producing products directly applicable as blending components and biojet fuel precursors.

Escalating global demand for nuclear energy has made uranium (U(VI)) an indispensable strategic resource. Limited terrestrial uranium reserves and widespread uranium-contaminated wastewater have spurred research into uranium recovery and remediation technologies. Adsorption is the most promising approach, yet conventional amidoxime (AO)-functionalized adsorbents suffer from low AO group utilization, sluggish adsorption kinetics, and poor structural stability in cyclic use. Herein, we report the rational design and synthesis of a novel amphiphilic block copolymer (polystyrene-block-polyamidoxime, PS-b-PAO) via reversible addition–fragmentation chain transfer (RAFT) polymerization and subsequent amidoximation. This copolymer spontaneously self-assembles into core–shell nanomicelles in aqueous media, with a hydrophobic polystyrene (PS) core and a hydrophilic PAO shell, ensuring full exposure of AO groups to enhance coordination with uranyl ions (UO22+). Systematic adsorption tests showed that PS-b-PAO nanomicelles exhibit an ultrahigh uranium adsorption capacity of 916.14 mg·g–1 in uranium-spiked aqueous solutions, 4.27 times higher than that of linear polyamidoxime (PAO) under the same conditions and 4.01 times higher than that of poly(styrene-co-acrylonitrile) under identical conditions. Kinetic and isotherm analyses indicated the adsorption follows the pseudo-second-order kinetic model and Langmuir isotherm model, dominated by chemisorption and monolayer coordination between AO groups and UO22+. The adsorbent also has excellent selectivity for U(VI) over interfering metal ions (V5+, Fe3+, Cu2+, and Co2+), superior recyclability (retaining over 87% uranium removal efficiency after 5 adsorption–desorption cycles), and a satisfactory uranium adsorption capacity of 5.28 mg·g–1 in natural seawater. X-ray photoelectron spectroscopy (XPS) confirmed that the adsorption mechanism involves chelation of UO22+ by nitrogen and oxygen atoms in the AO moieties of PS-b-PAO.

Methacrolein (MAL) as an intermediate of methyl methacrylate is produced from C4 selective oxidation, which faces the challenging problems of selectivity control and petroleum depletion; therefore, the aldol reaction of formaldehyde with propionaldehyde receives great attention. In this work, we developed an effective plug flow reaction process for continuous methacrolein synthesis catalyzed by an efficient sec-amine-based ionic liquid with low dosage at enhanced temperature (100–160 °C) and pressure (1–5 MPa). The effects of the cation and anion structure, as well as reaction conditions, on the catalytic performance were systematically investigated for further optimization. Main side reactions including methylation of sec-amine group in cation, self-condensation of propionaldehyde, and dimerization of MAL were identified by (GC–MS) for the construction of reaction networks. It was found that the combination of N-methylcyclohexylamine and benzoic acid for ionic liquid preparation achieved the highest catalytic performance of 99.8% propionaldehyde conversion and 98.1% MAL selectivity under optimal condition. Reaction orders and activation barriers of both main and side reactions were determined, which enabled the establishment of four-step coupled kinetic model with regression deviation within 5%. Recycling tests revealed that the catalyst deactivation was mainly derived from irreversible N,N-dimethylcyclohexylamine formation; however, it could be economically recovered to partially compensate catalyst loss.
