A novel ferroelastic domain reconfiguration mechanism delivers giant thermo-optic response in sol–gel barium titanate (BTO) thin films. • 750 °C-annealed BTO achieves record thermo-optic coefficient of 9.69×10⁻⁴ °C⁻¹, multiple times higher than silicon. • Fully reversible a-c domain switching is realized within the practical 25 °C-100 °C working window for on-chip photonic devices. • Prototype Fabry-Pérot modulator reaches 40% modulation depth for photonic integrated circuits and wavelength selective switching. • The domain engineering strategy is potentially extendable to CMOS-compatible ferroelectric perovskites. Thermo-optic tuning in ferroelectric perovskites has emerged as a promising strategy for achieving broadband, energy-efficient optical modulation. Nevertheless, the physical origins governing the near-room-temperature thermo-optic response of ferroelectrics are still not clearly defined. In this work, we report a previously unexplored thermo-optic mechanism in sol-gel-processed (001)-oriented BaTiO₃ films. This mechanism is driven by thermally induced, reversible a-c ferroelastic domain switching, activated through the synergistic control of interfacial screening, domain, and defect engineering, resulting in a large change in refractive index in the 25°C-100 °C temperature range. Films crystallized at 750 °C exhibit high tetragonal phase purity, strong c-axis alignment, and an exceptional thermo-optic coefficient of 9.69×10 -4 °C⁻¹—over several times larger than that of crystalline silicon—together with reversible domain evolution upon thermal cycling. A Fabry-Pérot thermo-optic modulator incorporating this film delivers 40% intensity modulation in the C-band. These findings establish a ferroelastic-domain-driven route to thermo-optic enhancement in ferroelectric perovskites and lay the groundwork for scalable.

A multifunctional composite, designated as ZIF-8@LY/ZIF-8@CDs-Eu 3+ , was rationally designed as a fluorescence probe and high-performance photocatalyst for simultaneous detection and degradation of oxytetracycline (OTC). To address the critical challenge of co-encapsulating fluorescein (LY) and Eu 3+ -functionalized carbon dots (CDs-Eu 3+ ) within a single porous particle without functional incompatibility, we proposed a core-shell ZIF-8 architecture, where the etched ZIF-8 core served as the host for LY loading, and the in situ grown ZIF-8 shell was introduced to immobilize CDs-Eu 3+ . The acetic acid etching of the ZIF-8 core created abundant sites to absorb more LY molecules, which further enhanced the OTC removal efficiency. On this basis, a fluorescence “turn-on” ratiometric quantitative detection platform for OTC was established, with a low limit of detection (LOD) of 1.8 nM. Meanwhile, the ZIF-8@LY/ZIF-8@CDs-Eu 3+ composite achieved 99% OTC removal within 300 min under light irradiation, driven by the generated reactive species including superoxide radicals (·O 2 − ), hydroxyl radicals (·OH), and photogenerated holes (h + ). Notably, three parallel degradation pathways of OTC were identified via high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS). This work not only provides an innovative strategy for the design of multifunctional MOF-based composites, but also opens a new avenue for the efficient monitoring and elimination of antibiotic residues in complex environmental matrices.

A novel ternary UiO-66- g -P4VP/CsPbBr₃ composite is rationally designed. • It achieves a high CO₂ reduction rate of 85.2 μmol g −1 h −1 under visible light. • The P4VP interlayer acts as a CO₂ adsorber and charge-transfer bridge. • A direct Z -scheme mechanism ensures efficient charge separation. Polymer interfacial engineering is developed to overcome the intrinsic charge-transfer barriers and instability caused by insulating ligands in MOF/perovskite composites. By covalently grafting poly(4-vinylpyridine) (P4VP) brushes onto UiO-66-NH₂, followed by in-situ confined growth of CsPbBr₃ quantum dots (QDs), we construct a ternary UiO-66- g -P4VP/CsPbBr₃ (UPC) photocatalyst. The P4VP interlayer serves triple synergistic functions including coordinating Pb 2+ to anchor ultrasmall monodisperse QDs, providing a charge transfer bridge for interfacial charge transfer, and enriching local CO₂ concentration. The optimized UPC-2 achieves an electron consumption rate of 85.2 μmol·g −1 ·h −1 for CO₂ reduction under visible light, 8.5 times that of pristine UiO-66-NH₂, with outstanding stability. Comprehensive spectroscopic, photoelectrochemical, and transient photovoltage analyses confirm a direct Z -scheme charge transfer mechanism that preserves strong redox potentials while suppressing interfacial recombination. This work establishes a versatile polymer-bridge strategy for designing durable, high-performance MOF/perovskite heterojunctions for solar fuel production.

The development of hydrogel dressings that exhibit excellent moisturizing, antibacterial, and pro-healing properties is an urgent need in the field of wound healing. This study designs a multifunctional hydrogel dressing (QCPVA-ZnO) to address this challenge by incorporating a quaternized nanocellulose‑zinc oxide hybrid (QCNC-ZnO) into a polyvinyl alcohol/chitosan matrix. QCPVA-ZnO exhibited excellent moisture retention and breathability, with a water vapor transmission rate of 2440 g·m −2 ·day −1 and an oxygen permeability rate of 111 g·mm/m 2 ·day·kPa, which could be attributed to the synergistic effect of its porous structure and hydrophilic cross-linked network. The experiment of the full-thickness skin defect model in mice showed that QCPVA-ZnO had significant healing promoting ability, with a wound healing rate of 97.6% by day 11. This can be attributed to QCNC-ZnO endowing QCPVA-ZnO with a good bactericidal rate of 99%, which thereby enabled the latter to effectively control infections, reduce inflammatory reactions, and further promote angiogenesis and epidermal regeneration. In addition, biosafety evaluations indicated that QCPVA-ZnO had a cell survival rate of over 90% and hemolysis of less than 2%, demonstrating good biocompatibility. This study improves the moisturizing, air permeability, antibacterial and healing promoting functions of the hydrogel, providing a new idea for the development of multi-functional wound dressings.

A three-channel sensor array based on Au@Pt NPs was constructed. • Au@Pt NPs with dual-function characteristics was designed. • Discrimination of light aroma-type Baijiu (LAB) was achieved. • Different years, production processes, price gradients, and adulterated were analyzed. • This method highlighted simple to operate, rapid in detection. The development of light aroma-type Baijiu (LAB) industry proposes a growing need for developing rapid and accurate discrimination method for the quality control of LAB. This study innovatively constructed a dual-mode three-channel sensor array based on the gold/platinum nanoparticles (Au@Pt NPs) with surface engineering. In this case, two colorimetric sensor channels based on ascorbic acid/para-aminophenol-chloroauric acid-nanozyme (AA/ pAP-HAuCl₄-Au@Pt NPs) and one fluorescent sensor channel based on nanozyme‑hydrogen peroxide- o -phenylenediamine (Au@Pt NPs-H₂O₂-OPD) were established. Experimental results demonstrate the colorimetric and fluorescence mode can accurately quantify four organic acids and three aldehydes in Baijiu, respectively. Samples including 17 different years and 9 different production processes of basic liquors of LAB, 48 different price gradients of commercial LAB, and adulterated LAB were analyzed. Discrimination with an accuracy exceeding 96% by Linear Discriminant Analysis, Hierarchical Cluster Analysis, and leave-one-out cross-validation was achieved. The dual-mode three-channel sensor array is characterized by simplicity, rapidity and accuracy, providing a new idea for the quality discrimination and market regulation of Baijiu.

Butylated hydroxyanisole (BHA) is a synthetic phenolic antioxidant widely used in edible oils and fat-containing foods. Excessive BHA poses significant risks to human health, thus making rapid and sensitive detection of BHA crucial for health protection. Herein, the Ag 2 CO 3 nanozyme was prepared by the simple precipitation method, which exhibits both laccase-mimic and oxidase-mimic activities. It was found that the oxidase-mimic activity of Ag 2 CO 3 facilitated the conversion of TMB to its blue oxidized form (oxTMB), and subsequent addition of BHA resulted in the formation of a characteristic purple adduct. Additionally, BHA effectively suppressed the laccase-mimic activity of the Ag 2 CO 3 nanozymes. Therefore, a novel colorimetric sensor was constructed using the dual-enzyme-mimic activities as a sensing signal for rapidly detecting BHA in edible oil. The colorimetric sensor achieves limits of detection (LOD) for BHA as low as 1.1 μM in the laccase-mimic channel and 0.08 mM in the oxidase-mimic channel, both of which are substantially lower than the maximum permissible BHA level in edible oils stipulated in Chinese National Food Safety Standard GB 2760. The sensor developed in this work shows great promise for application in the field of edible oil detection.

The esterase-mediated esterolysis is the key for specific butyrate production. • Carboxylesterase assay verified the involvement of esterases during the fermentation. • The classical metabolic pathway for nonspecific butyrate production is altered. Butyrylated starch is a special type-4 resistant starch with butyrate-carrying attribute. In this study, the unique butyrate-producing capability of butyrylated starch was deeply investigated by focusing on its specific and nonspecific butyrate-producing pathways, respectively, using specially designed substrates as controls. In vitro fermentation studies revealed that butyrylated and isobutyrylated starches generated high levels of butyrate and isobutyrate, respectively, highlighting the role of butyryl group metabolism in the specificity of butyrate production. Carboxylesterase assays have demonstrated that butyryl group metabolism is primarily facilitated by carbohydrate esterases expressed in the gut microbiota. Combined with 16S rRNA sequencing and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, it was found that butyrylated starch fermentation did not significantly enhance traditional butyrate synthesis pathways but modified the balance between the butyryl-CoA:acetyl-CoA transferase and butyrate kinase pathways by altering the gut microbiota composition, specifically by upregulating the relative abundance of indicator species such as Bacteroides , the Lachnospiraceae_NK4A136_group , and Parabacteroides . These insights offer theoretical guidance for designing butyrylated starch structures and regulating intestinal health. Download: Download high-res image (169KB) Download: Download full-size image

Collagen is an ideal raw material for biological fibers, yet achieving long-range structural order and the resultant high-strength fibers without toxic crosslinkers remains a major challenge. This work integrates ultrasonic fragmentation with dialysis concentration to induce a stable lyotropic liquid crystalline (LC) collagen dope at a concentration as low as 3.3%, which is significantly lower than previously reported. Ultrasonic treatment reduced collagen fragment length to 10–30 nm, lowering steric hindrance and enhancing molecular mobility, thereby promoting nematic LC formation. Rheological analysis revealed that at 3.7%, the spinning dope exhibited a characteristic viscosity plateau in the low shear rate range of 1–5 s −1 , indicating shear-induced alignment of nematic LC domains, which defines the optimal spinning window. Using 4.0% LC dope and an optimized ethanol flow rate of 0.30 mL/min in microfluidic spinning process, the resultant collagen fibers achieved a high tensile strength of 2.21 cN/dtex and a thermal denaturation temperature of 120.8 °C. Increasing the spinning dope concentration progressively reduced lateral molecular packing distance, transformed the fiber surface from grooved to smooth, and enhanced thermal stability. This study establishes a rational, crosslinker-free strategy to fabricate high-performance pure collagen fibers with superior mechanical and thermal properties, providing critical theoretical and technical support for their application in absorbable surgical sutures and regenerative medicine.

The trade-off between permeability and selectivity is a longstanding challenge in nanofiltration membranes that critically limits their practical performance in dye/salt separation. In this work, we present the rational design and fabrication of a series of alkoxy side chain–functionalized covalent organic polymer (COP) thin-film composite membranes (Bth-PEOx) on polyacrylonitrile (PAN) ultrafiltration supports via interfacial polymerization. The resulting membranes enable precise modulation of the nanoscale transport microenvironment—specifically, pore size distribution and surface hydrophilicity—through controlled incorporation of alkoxy side chains of varying length. The optimized Bth-PEO2 membrane achieves highly efficient dye/salt separation in Congo red (CR)/NaCl mixtures, delivering a high water permeance of 45.6 L m −2 h −1 bar −1 , >99% CR rejection, minimal NaCl rejection (6.23%), and an exceptional CR/NaCl separation factor of 117. In addition, the Bth-PEOx membranes exhibit outstanding chemical robustness across extreme pH conditions, superior mechanical resistance to hydraulic compaction, and stable performance during continuous filtration processes. This side chain engineering strategy overcomes the classic permeability–selectivity trade-off by enabling simultaneous improvement of both permeability and selectivity, thereby establishing a scalable, structure–property–guided design paradigm for energy-efficient dye/salt separation and advancing the practical treatment and resource recovery from high-salinity textile wastewater.

Backgroud Immunosuppressant tacrolimus (TAC) induces glucose metabolism disorder and diabetes mellitus (DM) closely associated with intestinal microbiota dysbiosis and reduced bile acid levels, and this study aimed to explore the ameliorative effect and underlying mechanism of hyodeoxycholic acid (HDCA) on TAC-induced DM in rat models. Methods We first verified the critical role of intestinal microbiota and bile acids in the pathogenesis of TAC-induced DM via antibiotic-induced gut microbiota depletion, then orally administered HDCA (100 mg/kg) to TAC-induced diabetic rats to evaluate its protective efficacy, detecting glycolipid metabolism indices, targeted bile acid omics, FXR/TGR5 protein expression, serum and ileal GLP/FGF15 levels, and mRNA levels of key metabolic genes including Cyp7a1, Cyp27a1, Cyp7b1, Cyp8b1, Fgfr4, Creb1 and Ppargc1a . Results Antibiotic treatment significantly reduced BSH-active gut microbiota such as Bacteroides and Lactobacillus , disrupting the serum bile acid pool and exacerbating diabetic symptoms by altering the gut microbiota-bile acid axis; while HDCA administration markedly improved glucose tolerance and reshaped bile acid profiles in TAC-induced diabetic rats, specifically lowering serum and fecal 12-OH/Non-12-OH BAs ratio via downregulating hepatic Cyp7a1 and upregulating hepatic Cyp8b1 expression. HDCA also suppressed enteroendocrine cell-derived GLP-1 secretion, decreased serum and ileal FGF15 levels, and reduced the expression of ileal FXR as well as hepatic Creb1 and Ppargc1a. Conclusions Collectively, HDCA exerts a significant ameliorative effect on TACinduced DM by regulating metabolic enzymes and altering bile acid profiles, with the core mechanism involving inhibited enterohepatic FXR-FGF15 axis, increased GLP-1 secretion and suppressed hepatic gluconeogenesis, all of which play key regulatory roles in this protective process.

Fresh pork remains susceptible to psychrotrophic spoilage during superchilled storage. Although oregano essential oil (OEO), nisin, and active absorbent pads have each been studied, their effects on spoilage-community proliferation and concurrent quality loss remain poorly resolved. Here, we coupled longitudinal 16S rRNA gene profiling with conventional microbiological and quality measurements to evaluate a poly(vinyl alcohol)/soy protein isolate pad containing OEO-loaded soluble soybean polysaccharide-nisin nanoparticles (PS-NPs). Pork was stored at −1 °C for 24 days without a pad (CK), with a nanoparticle-free pad (PS), or with PS-NPs. Bacterial communities in CK and PS-NPs were profiled alongside total viable count, TVB-N, TBARS, protein carbonyls, color, water-holding capacity, and sensory quality. Compared with CK, PS-NPs slowed the increase in viable counts and delayed physicochemical and sensory deterioration. On day 24,Pseudomonasrelative abundance was 39.48% with PS-NPs and 51.02% in CK. TBARS and protein carbonyl contents were 36.96% and 19.44% lower than CK, respectively, while cooking loss was 28.49% versus 32.18%. Among the evaluated taxon-quality pairs,Pseudomonas psychrophilashowed the strongest positive association with protein carbonyl content. Unlike earlier performance-focused studies, this work links packaging-associated community shifts with concurrent chemical, physical, and sensory changes under superchilling. The findings support PS-NPs as a preservation strategy.

Excessive phosphorus input drives eutrophication, threatening aquatic ecosystems and water security. However, efficient phosphorus removal and facile adsorbent recovery remain key challenges in wastewater treatment. To remove phosphorus from water while efficiently recovering adsorbents, this study proposes an innovative chitosan-based adsorption dynamic membrane (ADM) system, aiming to achieve simultaneous phosphorus removal and adsorbent recovery, thereby integrating environmental protection with resource recovery. In this study, system performance was enhanced through the optimization of key operational parameters. The results showed that a higher Ca-PAC-CTS concentration increased filtration resistance, accelerated dynamic membrane formation, and improved adsorbent recovery efficiency. Increasing the flow rate facilitated the rapid development of transmembrane pressure and reduced effluent turbidity, thereby contributing to more effective pollutant removal. The optimal operating conditions were determined as a flow rate of 4.8 L/h, a Ca-PAC-CTS concentration of 1.0 g/L, and a hydraulic retention time of 5 min, under which phosphorus removal and adsorbent recovery efficiencies both exceeded 80%. Overall, this study highlights the potential of ADM systems for efficient phosphorus capture and adsorbent recovery, providing support for the development of sustainable and low-carbon technologies in wastewater treatment.
