The rational integration of support structures and alloying strategies is crucial for developing highly active and durable catalysts to advance fuel cell technology. This study presents a polyaniline-supported palladium-nickel alloy catalyst (Pd 7 Ni 3 -PANI) with an electronic structure modulated by synergistic metal-support interaction and lattice strain and shows significantly enhanced electrocatalytic performance for ethylene glycol and ethanol oxidation (EGOR/EOR). For EGOR/EOR, the Pd 7 Ni 3 -PANI catalyst shows mass/specific activities (5396/2541 mA mg Pd -1 , 33/15 mA cm −2 ), surpassing those of commercial Pd/C (724/565 mA mg Pd -1 , 12/9 mA cm −2 ). Moreover, Pd 7 Ni 3 -PANI also demonstrates superior CO tolerance and electrochemical stability. These improvements are attributed to the oxyphilic Ni facilitates the generation of hydroxyl (OH – ) to accelerate CO oxidation, while simultaneously optimizing the electronic state of Pd to regulate the adsorption of reaction intermediates. This work provides a new strategy for designing cost-effective and efficient anode electrocatalysts.

To address the challenge of fruit spoilage, this study developed an eco-friendly composite film (CGTZ-P) with dual functionality for gas regulation and ethylene adsorption. The film incorporates biodegradable PBAT microspheres to form porous gas-permeable channels and mesoporous nano-zeolites modified with tannic acid as ethylene scavengers. The optimized CGTZ-P1 formulation demonstrated remarkable mechanical enhancement, with tensile strength and elongation at break increasing by 455.84% and 49.45%, respectively, compared to the control film. The composite film exhibited improved CO₂/O₂ selectivity, strong antioxidant activity (DPPH radical scavenging: 72.10%; ABTS radical scavenging: 81.22%, and effective antibacterial effects against both Staphylococcus aureus and Escherichia coli . In the strawberry storage trial, the CGTZ-P1 film extended the shelf life by over 7 days at room temperature by maintaining fruit freshness, reducing weight loss, and delaying pH changes. This work provides a sustainable approach for developing multifunctional biodegradable packaging materials for fruit preservation.

It is challenging to develop well-designed photocatalysts with high activity. In this work, TiO 2 nanotubes (TiO 2 -NTs，TNT) with well-morphology and high {001} facets exposure ratio were directly synthesized by H 3 PO 4 /HF-assisted two-step anodic oxidation. The results show that the addition of 3 wt% H 3 PO 4 and 0.5 wt% HF into the electrolyte facilitates the preparation of TiO 2 -NTs with an average crack density of 0 % and {001} facets exposure ratios up to 80.00 %. Moreover, the PO 4 3- and HPO 4 2- in the anode effectively hinder the generation of electron current and release of oxygen bubbles on the surface of Ti substrate, which reduces the surface cracks of TiO 2 -NTs. The F - in the electrolyte is adsorbed on the {001} facets of the TiO 2 -NTs, which decreases the energy of the O-Ti-O, thus achieving the purpose of high {001} facets exposure ratio. Ultimately, the excellent optical properties, in conjunction with the synergistic effect of {001} facets-selective orientation and O V , significantly enhanced the photocatalytic activity of TiO 2 -NTs, resulting in the removal of 90.32 % Rhodamine B in 120 min under visible light illumination. This work could shed light on the new approach to the rational design of high-efficiency TiO 2 -NTs-based photocatalysts.

Alkaline water electrolysis (ALK) faces technological challenges including low electrolysis efficiency, high energy consumption, and limitation of membrane technology. Herein, we report a nickel-polyethersulfone (Ni-PES) composite membrane modified by platinum (Pt) to function simultaneously as a highly active hydrogen evolution reaction (HER) electrode and a hydrogen-selective membrane. The Ni-PES membrane was prepared by phase inversion tape casting and atmospheric sintering, in which PES polymer provides the structural skeleton and metallic nickel serves as the electronic conductor and HER catalyst. Moreover, proper heat-treatment changes the microstructure and hydrophobicity of Ni-PES membrane, and Pt electrodeposition significantly boosts HER activity. The optimized Pt@Ni-PES-400 membrane electrode achieves a low overpotential of 104.9 mV@100 mA cm −2 and a Tafel slope of 125.8 mV dec −1 in concentrated alkaline electrolyte (30 wt% KOH). Furthermore, we design and fabricate a H-type, diaphragm-free, and two-chamber electrolytic cell, which is separated by Ni-PES-based membrane. Such membrane-based H cell realizes the combination of hydrogen production and separation processes: the in-situ generated hydrogen via water electrolysis is transported through the Pt@Ni-PES-400 membrane to the gas collection chamber, with a hydrogen purity of up to 99.95 % and a hydrogen permeation rate of 0.18 mL min −1 cm −2 at an overpotential of −500 mV, and the cell performance remains stable during 100 h of operation.

The integration of multiple photonic stopbands into a single microparticle is a coveted goal for advancing multiplexed sensing and high-capacity information encryption. However, conventional fabrication methods typically rely on the complex integration of different colloidal building blocks in terms of sizes or compositions, which increases cost and limits scalability. Herein, we report a facile and scalable strategy for fabricating cylindrical photonic microparticles with tunable dual stopbands from a single photonic composition, thereby eliminating the reliance on different colloidal building blocks. Our approach synergistically combines micromolding with a magnetic field-assisted selective etching process. The incorporation of ferromagnetic barium ferrite nanoparticles (BaFe 12 O 19 NPs) enables precise orientation control of the microparticles, which is pivotal for the site-specific protection and etching that integrates both opal and inverse opal structures into a single microparticle. The ratio between these two distinct photonic regions can be readily tuned, allowing for customizable photonic properties and structural colors. Furthermore, we demonstrate the extensibility of this method by creating multi-segment photonic microparticles with more than two stopbands. Due to the different wettability between the opal and inverse opal regions, the microparticle array exhibits adjustable hydrophilicity and hydrophobicity and potentially possesses antifouling capability. These programmable microparticles, with their anisotropic and tunable optical characteristics, together with tunable hydrophobicity, offer significant potential for developing next-generation information encoding platforms, anti-counterfeiting technologies and displays, and even antifouling pigments.

Ni-based catalysts have been extensively investigated for lignin hydrogenation; however, they often exhibit limited phenol selectivity and poor catalytic stability. To address these challenges, we introduced Cu as a promoter, resulting in the development of NiCu/ZSM-5 catalysts with significantly enhanced phenol selectivity and durability. Characterization studies revealed that Cu species form an alloy structure with Ni, which effectively suppresses the sintering of Ni nanoparticles during the catalytic process, thereby maintaining consistent performance over multiple reaction cycles. Furthermore, the Cu-Ni alloy demonstrated improved hydrogen activation capability while reducing overall H2uptake, leading to a marked increase in phenol selectivity compared to the Cu-free Ni/ZSM-5 catalyst. As a result, the Ni1Cu1/ZSM-5 (Ni/Cu molar ratio = 1:1) catalyst achieved a lignin conversion of 69.8% and a phenol selectivity of 84.4%, with negligible performance degradation over 8 cycles. The strategy presented in this work may offer an effective approach for enhancing the performance of industrial catalysts in lignin upgrading processes.

Gallic acid (GA) exhibits excellent antioxidant properties but suffers from chemical instability due to its carboxyl group, which limits practical application. To address this, we designed and investigated 14 distinct ester derivatives of GA, which were categorized into two major groups based on their substituents: chain alkyl and hydroxyl-substituted alkyl groups. Systematic evaluation revealed a striking decline in the DPPH radical scavenging activity of alkyl esters with increasing carbon chain length, from 91.9% for GA-C3 to 55.6% for GA-C30. The hydroxyl-functionalized GA esters GA-EG, GA-GL, and GA-PT maintain high antioxidant activity (>90%) while improving applicability through carboxyl substitution. In the oil system, all derivatives significantly prolong the oxidation induction time, with GA-C3 exhibiting the highest performance by extending the induction time by 2.15 h. Hydroxyl-functionalized esters such as GA-EG, GA-GL, and GA-PT also demonstrated significant efficacy, prolonging oxidation induction by 1.92 to 2.03 h. The results suggest how the structure of GA esters affects their antioxidant behavior, providing a direction for designing antioxidants suitable for specific systems.

Background/Objectives: The novel wave electric toothbrush is considered potentially helpful in removing subgingival plaque to prevent the occurrence of periodontal diseases. This study aimed to assess the cleaning efficacy of a novel wave electric toothbrush on subgingival plaque and its safety profile for oral soft tissues.Methods: In vitro cleaning efficacy evaluations were conducted using oral dental models. The wave electric toothbrushes were divided into low-, medium-, and high-swing parameter groups, with manual brushing (Bass technique) as the control. Simulated plaque was applied to the buccal and gingival sulcus sites of the four first molars, and the plaque removal area and sulcus cleaning depth were measured. For safety evaluation, Sprague Dawley (SD) rats were brushed on their molars daily for 30 days, with bleeding incidents recorded. Oral soft tissues were analyzed through H&E staining and immunohistochemical analysis. Statistical analysis included ANOVA and Kruskal–Wallis (p< 0.05).Results: Medium- and high-swing groups demonstrated superior gingival sulcus cleaning efficacy, showing significant differences compared with the low-swing and control groups (p< 0.05). All swing parameters achieved complete plaque removal on buccal surfaces. No significant differences were observed between the low-swing and manual groups, or between the medium- and high-swing groups, regarding sulcus cleaning efficacy and maximum sulcus depth. During the 30-day in vivo experiment, medium- and high-swing groups showed low bleeding frequencies, primarily at the palatal gingiva and vestibule. Histological analyses indicated that higher swing parameters increased the likelihood of soft tissue injury.Conclusions: Wave electric toothbrushes enhance subgingival plaque removal, with higher swing parameters improving gingival sulcus cleaning. However, stronger parameters may increase the risk of soft tissue damage. Further clinical studies are required to establish optimal guidelines.

Processing techniques determine the quality of tea. This study elucidates the impact of refiring process on Fenghuang Dancong Tea (FDT) under controlled experimental conditions by integrating sensory evaluation, non-targeted metabolomics (UPLC-MS/MS), and flavoromics (HS-SPME-GC × GC-TOF-MS). The results indicate that the decrease in polyphenols of the FDT mainly resulted from their transformation through the phenylpropanoid biosynthesis pathway during refiring, thereby reducing the bitterness and astringency of the tea while enhancing its sweetness. Although volatile diversity decreased with higher temperatures, the content of key aroma-contributing hydrocarbons and ketones peaked at 90 °C. Relative odor activity value (ROAV) analysis identified 9 key aroma compounds (ROAV ≥1), with 2-methyl-butanal, (E)-2-nonenal, 2-pentyl-furan, and 2,3-butanedione being the most impactful. This study provided a comprehensive investigation into metabolite changes during the refiring process of FDT, contributing valuable insights for precisely utilizing the refiring technique to improve the quality of tea.

This study investigated the effects of chronic MC-LR exposure (0 μg/L [Control], 1 μg/L [M1], 3 μg/L [M3], 10 μg/L [M10], and 30 μg/L [M30]) on the muscle nutrient composition, meat quality, and muscle proteomic profile of Nile tilapia (Oreochromis niloticus). In the high-dose group (M30), MC-LR exposure compromised the muscle antioxidant status of Nile tilapia, resulting in reduced meat quality, as evidenced by decreased pH value and water-holding capacity, elevated lipid/protein oxidation, and altered texture parameters (shear force and fragmentation index). Proteomic analysis further revealed a downregulation of proteins associated with ribosomes, suggesting an impairment of muscle protein synthesis in the M30 group. Moreover, despite chronic exposure, only low levels of MC-LR accumulated in the muscle tissue, indicating a negligible health risk to consumers. Collectively, these findings offered valuable insights into the impact of environmental MC-LR contamination on fish muscle quality and nutritional value.

In order to reduce the pollution of electronic waste, mixed-acid-doped poly aniline (TSPANI) was prepared via in situ solution polymerization, while poly(butylene succinate) (PBS) was synthesized by direct esterification. TSPANI and PBS were then blended in solution to fabricate a conductive and biodegradable polymer composite film (TSPANI/PBS). TSPANI and PBS are combined through intermolecular interactions. The addition of an appropriate amount of TSPANI improves the mechanical properties of the film while enhancing its electrical conductivity. When the TSPANI content reaches 20%, the semicircular arc diameter is minimized, indicating the lowest charge transfer resistance of 3.16 MΩ and optimal electrical conductivity. The film maintains excellent conductivity even under bending and twisting conditions. Concurrently, the film surface exhibits significant collapse and pores compared to other proportions, resulting in a faster degradation rate─achieving 34.3% after 42 days of enzymatic degradation and 35.75% after 180 days of soil degradation. When tested under various pressures, human motion, joint movement, and other subtle pressures, the sensor based on this electrically conductive film could effectively capture these changes and generate corresponding current responses. Furthermore, compatibility simulations conducted via Materials Studio software systematically evaluated the interfacial interactions in the TSPANI/PBS composite system, elucidating at the molecular level the formation of a hydrogen-bonding network and its role in enabling proton-hopping transport and synergistic electron conduction. The development of this composite material serves as a promising alternative to nondegradable polymers, effectively mitigating electronic waste pollution and contributing significantly to environmental protection.

Purpose In this study, we report the design and evaluation of Anlo@MOF-Lipo (AML), a liposome coated, small sized MIL-101(Fe) metal-organic framework (MOF) for targeted delivery of the multi target tyrosine kinase inhibitor anlotinib in lung cancer treatment.Methods In detail, the biomimetic liposome shell enhances nanoparticle biocompatibility, while the MIL-101(Fe) core enables pH responsive release of Fe3⁺ under acidic tumor conditions, triggering Fenton-like reactions and generating cytotoxic reactive oxygen species. Anlotinib is encapsulated within the MOF pores for sustained, intratumoral release, suppressing the growth of tumors.Results Characterization confirmed uniform liposome coating and sustained anlotinib release of AML. In vitro, AML demonstrated superior cellular uptake and cytotoxicity in lung cancer cells. In a murine subcutaneous tumor model, AML treatment achieved a greater tumor volume reduction than free anlotinib, with no observable systemic toxicity. Furthermore, in the orthotopic lung cancer model, AML achieved the most pronounced therapeutic efficacy among all treatment groups.Conclusion This dual mode therapeutic strategy-combining targeted chemotherapy with oxidative stress induction-highlights the potential of AML as a promising nanomaterial for improving lung cancer treatment.
