2-Methoxy-4-methylphenol (MMP), a biofuel and flavor, can be produced from lignin-derived vanillin via hydrodeoxygenation (HDO). Herein, CuPd nanoalloys were confined within SBA-15 for vanillin HDO. By tuning Cu/Pd mass ratio, a volcano-like trend in MMP yield and apparent turnover frequency (TOF) was observed. The optimized CuPd nanoalloy catalyst (Cu/Pd = 1) occupied the top position, achieving 96.3% MMP yield within 3 h, with the TOF of 323.5 h −1 , 3 times than that of monometallic Cu catalyst, while other CuPd nanoalloy catalysts, positioned either side, exhibited lower activities. Moreover, it maintained HDO activity over 20 runs, far beyond typical Cu catalysts (~5 runs). Fabricated via microwave-assisted strategy, the catalysts were confirmed by X-ray absorption fine structure and density functional theory calculations to form CuPd nanoalloys with Pd δ- and Cu δ+ pairs, enabling H 2 dissociation and C=O bond activation. This work demonstrates an efficient approach to robust and stable nanoalloy catalysts for biomass upgrading.

The catalytic oxidation of aromatic sulfides under mild, ambient conditions facilitates the high-value utilization of diesel fuel, free from external heating sources. Herein, a high-performance confined catalyst through a simple one-pot method is developed, denoted as HPW@ZIF-8. The phosphotungstic acid is encapsulated and confined within the pores of the ZIF-8 framework, achieving ambient temperature catalytic oxidation of aromatic sulfides to high-value sulfones. The induced charge shift in the confined catalysis is observed, as the weak interaction force between the phosphorus-tungsten structure and Zn center, strengthening the catalytic oxidation performance. Under unheated conditions, the hydrogen peroxide utilization rate and activity of the catalyst at ambient temperature are both greater than 97.0%. In addition, the confined catalysts exhibit good cycling performance after 10 cycles, attributed to the highly matched host and guest, with only 0.2% HPW loss. Above all, this work offers new insights for the green, low-energy consumption, and high-value utilization of diesel fuel. Graphical Constructing confined catalytic materials by encapsulating active centers in the cavities of ZIF-8 metal-organic frameworks. This strategy enables the efficient catalytic oxidation of sulfur-containing compounds in diesel to high-value sulfone products at ambient temperatures. This produces ultra-low diesel with a sulfur content of less than 10 mg/L.

Polyacrylamide (PAM) hydrogels are promising candidates for flexible wearable sensors but suffer from limitations including toxic cross-linkers(N,N′-methylenebis(acrylamide), BIS), prolonged gelation times, high-temperature requirements, and inadequate mechanical properties. Herein, a quadruple-functional MXene was employed to fabricate high-performance PAM hydrogels within 5 min at ambient temperature. MXenes served simultaneously as an initiating accelerator (replacing toxic BIS), physical cross-linker, conductive agent, and reinforcing nanofiller. Reductive MXene nanosheets catalyzed ultrafast polymerization of acrylamide monomers via redox reactions with ammonium persulfate(APS), facilitating a green, low-energy fabrication process and preventing MXene nanosheets reaggregation within the hydrogel network. By adjusting the MXene content, the optimized hydrogel (6 mg/mL MXene) demonstrated exceptional mechanical performance, with 1558% elongation at break and 119 kPa tensile strength, exceeding traditional BIS/PAM hydrogels (1081% elongation, 74 kPa strength). This enhancement is attributed to the uniform honeycomb-like porous structure and dual-network architecture comprising covalent PAM backbone and physical hydrogen-bonded MXene cross-links. Additionally, the MXene incorporation confers electrical conductivity (0.3 S/m) and photothermal performance, with temperature increase up to 21.8 °C under near-infrared (NIR) irradiation and good photothermal stability. As a strain sensor, the hydrogel exhibits two-stage sensing response with gauge factor (GF) of 1.1 (0–235%) and 2.4 (235–400%), rapid response time (35 ms), recovery time (98 ms), and excellent cyclic stability. In L929 cytotoxicity assays, MXene/PAM hydrogels demonstrate improved biocompatibility compared to BIS/PAM hydrogels. The sensor accurately monitors both large human movements (finger, wrist, bending, handwriting) and subtle physiological activities (pulse and throat vibrations). This study introduces a rapid, eco-friendly method for fabricating multifunctional PAM hydrogels with enhanced mechanical, conductive, photothermal, and biocompatible properties for flexible electronic skin and biomedical devices.

Osmotic energy harvesting from salinity gradients represents a promising and sustainable pathway for renewable energy generation. While reverse electrodialysis (RED) is a viable technology for extracting this energy, conventional ion-selective membranes often suffer from inadequate surface charge density and limited mechanical strength, severely hindering their large-scale application. Herein, we fabricated a mechanically robust aramid nanofibers (ANFs)/sodium alginate (SA) composite membrane. This design synergistically integrates the abundant ionic groups of SA with the robust mechanical framework of ANFs, resulting in simultaneous enhancements in structural stability and charge transport properties. The composite membrane achieves a tensile strength of 131.76 MPa, representing a 52.92% improvement over pure ANFs membranes. Benefiting from its balanced ion selectivity and mechanical integrity, the membrane yields a power density of 13.10 W/m2 under a 50-fold salinity gradient, which increases to 49.65 W/m2 under a 500-fold salinity gradient. Furthermore, under simulated alkaline wastewater conditions (pH 11), the membrane maintains a power output of 15.53 W/m2, confirming its potential for simultaneous wastewater treatment and energy recovery. These findings demonstrate that integrating nanofibers with biopolymers is an effective strategy for constructing durable, high-performance ion-selective membranes for sustainable osmotic energy utilization.

Production of jet fuels from renewable biomass is key to decarbonizing the aviation sector. In this work, valorization of the aromatic macromolecule lignin in plant biomass toward monocyclic and fused bicyclic alkanes was proposed. The lignin was first depolymerized toward prop-1-enyl-substituted monomers with high selectivity (>70%) using ethanol as the solvent in the absence of external H2. Alkylation of these monomers with hemicellulose-derived 2-methylfuran using solid acids such as Amberlyst 35 generated alkylation products (yield >80%) along with a small amount of dimers. The alkylation products can be hydrodeoxygenated toward monocyclic alkanes using Ru/C and zeolites, where the product distribution can be controlled by the microporosity of the zeolite. C14 is the major product using Ru/C and mordenite (MOR). The Friedel–Crafts dealkylation of the alkylation products can occur by using Beta and Y zeolites, leading to the formation of more C9. Using the same acid catalyst (i.e., Amberlyst 35) can almost quantitatively convert these monomers toward dimers, which can be hydrodeoxygenated toward fused bicyclic alkanes in the presence of hydrogenation catalysts and zeolites. However, the product distribution can be determined by the activity of the hydrogenation catalyst. C18 was obtained with high yield (>90%) using Pd/C and zeolites such as MOR and alkaline-treated Beta zeolite (Beta-AT). However, C12 was the dominant product (yield of 77.5%) using Raney Ni and alkaline-treated Beta-AT. This work paves a new way for the production of high-density cycloalkanes from recalcitrant lignin.

Among post ionic liquid electrodeposition metal technology, choline chloride-urea (ChCl-urea) deep eutectic solvent (DES) has received much attention due to its unique physicochemical properties as well as its simple and low-cost synthesis. Herein, ChCl-urea DES is innovatively used towards one-step electrodeposition to obtain aluminium sheet-like nanostructures. The electrochemical reduction behaviour of aluminium in ChCl-urea-AlCl3 DES is investigated using cyclic voltammetry, linear scanning voltammetry, and chronoamperometry. The effect of reaction temperature on the microstructure, chemical composition, and physical phase of the products is considered. The results indicate that the reduction of Al(III) in ChCl-urea-AlCl3 DES is a diffusion-controlled one-step three-electron transfer quasi-reversible process. The increase in temperature greatly enhances the cathodic reaction kinetics and drives the reduction of Al(III) to Al. The electrodeposition of aluminium in ChCl-urea-AlCl3 DES is consistent with the instantaneous nucleation model. High purity aluminium sheet-like nanostructures with a grain size up to 100∼200 nm are obtained by the reaction for 2 h at ambient temperatures. The product aluminium phases are indexed as typical (111), (200), and (220) crystal planes. This finding provides a theoretical guide for the preparation of aluminium sheet-like nanostructures by an environmentally friendly and facile electrodeposition method in ChCl-urea-AlCl3 DES.

Nickel foam filtration layers used in sand control screens for petroleum extraction often suffer from insufficient mechanical strength and poor corrosion resistance and wear resistance. In this work, a two-stage electroplating strategy using the same metal was employed to construct hierarchical nickel coatings on nickel foam substrates. The effects of key process parameters, including electroplating time, temperature, and pretreatment, on the microstructure, mechanical properties, electrochemical corrosion behavior, and tribological performance of the coatings were systematically investigated. Electroplating time was found to directly regulate grain size and coating uniformity, while electroplating temperature significantly influenced nickel deposition behavior and electrolyte stability. In addition, UV pretreatment markedly improved the brightness and homogeneity of the deposited layers. Under optimized conditions (UV pretreatment for 10 min, electroplating at 60 °C for 8 min), a dense and uniform nickel coating with a well-ordered crystalline structure was obtained, leading to significantly enhanced hardness, wear resistance, and corrosion resistance. This study presents a practical and highly reliable approach for fabricating high-performance nickel-based coatings on nickel foam filter layers. Anticipated for application in the oil extraction industry, this method is set to enhance the performance of foam metal sand control layers.

Royal jelly, a nutrient-rich bee product characterized by high water content and active components, is particularly susceptible to quality deterioration during storage. While temperature effects have been extensively documented, the specific role of light exposure in quality degradation remains largely unexplored. despite its relevance during production, handling, transportation, and display. This study systematically investigated the volatile organic compounds (VOCs) of royal jelly under different storage conditions using gas chromatography-ion mobility spectrometry (GC-IMS) combined with fingerprint analysis. Results from dual-column validation demonstrated that even short-term light exposure at 25 °C induced pronounced alterations in VOC profiles, triggering the accumulation of off-flavor aldehydes (e.g., hexanal, nonanal) and ketones, along with 2-furfural generated via Maillard reaction. Concurrently, characteristic fresh-aroma esters and alcohols were significantly depleted. Multivariate statistical analysis confirmed light exposure as the predominant factor driving quality deterioration, with temperature variation under dark conditions producing comparatively minor effects within the same short timeframe. This work provides the first systematic evidence establishing insights into early volatile changes in royal jelly and identifies key VOC markers that offer valuable insights for optimizing storage strategies and developing rapid quality monitoring protocols.

Perovskite quantum dots (PQDs) face significant performance limitations due to surface defects, which are not sufficiently addressed by conventional single-passivation methods. We introduce a dual-passivation strategy that synergistically combines bifunctional ligand 3-(N,N-dimethyloctadecylammonium)-propanesulfonate (SB3-18) treatment with silica coating to simultaneously passivate undercoordinated Pb2+ions and bromine vacancies in red-emitting CsPb(Br/I)3PQDs. This approach nearly triples the photoluminescence quantum yield (PLQY, from 23% to 58%). Systematic structural, morphlogical, binding energy, Fermi level and optical analyses confirm effective defect suppression and enhanced exciton luminescence. The dual-passivated sample QDs:SB3-18@SiO2also exhibit excellent environmental stability, retaining 85% of their initial emission after 30 min in air and exhibiting improved UV resistance. By combining the PQDs with a CGSO:Tb3+mechanoluminescent phosphor, a composite film is fabricated with bimodal optical response—color-selective photoluminescence under UV excitation and stress-activated green emission upon scratching. This work presents a robust route to high-performance PQDs and demonstrates their potential for advanced anticounterfeiting and smart optical applications.

Molybdenum disulfide (MoS2)-based composite systems are widely used as solid lubricating coatings. However, further optimization towards lower friction and higher wear resistance remains necessary to meet the extreme operating conditions and high reliability requirements of next-generation aerospace equipment. This study investigated the tribological performance of MoS2/epoxy composite coatings by comparing the effects of individual and combined additions of nano nickel (Ni) and magnesium silicate hydroxide (MSH). The coating preparation process adopted in this study is the bonding method. Experimental results showed that, under a load of 2 N and a rotational speed of 500 r/min, the coating containing 0.3 g Ni and 0.1 g MSH (labeled W03Ni01MSH) achieved a 22% reduction in wear scar width compared to the coating with only Ni, demonstrating a distinct synergistic effect. This is attributed to the complementary roles of the two additives: Ni promotes the formation of flaky wear debris, facilitating rapid formation and stabilization of a transfer film, thereby reducing friction; MSH enhances the load carrying capacity of the coating and suppresses wear propagation, thereby improving wear resistance. Furthermore, this composite coating exhibited optimal performance under the conditions of 500 r/min and 2 N. The results of this study significantly improved the friction-reducing and wear-resistant properties of the MoS2/epoxy composite coating. This provides a new strategy for the formulation design of high-performance solid lubricating coatings.

To address pipeline blockages and corrosion caused by moss, this study evaluates the effectiveness of two treatments, Isothiazolinone (IS) and layered double hydroxide–sodium pyrithione (LDH-SPT) modified hydrophobic resin membranes, in preventing moss growth. Furthermore, we closely examined how IS works at a molecular level to stop moss growth. The sequencing results revealed that the predominant algae identified in the pipeline moss community was a norank species ofTrebouxiophyceae, accounting for 75.79%. Tests show that IS has strong moss inhibition. It works at low doses (0.2%) and becomes even more effective as the concentration increases. Furthermore, IS remains highly effective at inhibiting moss within a modified hydrophobic resin membrane, but its corrosion resistance is poor. The LDH-SPT@IS composite modified hydrophobic resin membrane addresses the corrosion problem of using IS alone and still works very well at inhibiting moss. Finally, the mechanism of IS’s inhibition of moss was elucidated based on experiments and existing literature. It functions by disrupting moss cellular DNA structure and interfering with the mitochondrial electron transport chain. This research provides the basis for developing efficient, durable, and eco-friendly solutions to prevent pipeline corrosion and moss growth, paving the way for new technologies and materials.

Hard-healing or non-healing diabetic wounds feature complex pathogenesis, posing significant challenges to clinical treatment. Platelet-rich plasma (PRP) is rich in various growth factors and possesses significant therapeutic potential, while its clinical application is largely limited by the rapid release of these bioactive factors. In this study, a multifunctional hydrogel dressing (GACP@PRP) based on PRP was fabricated for the promotion of type 2 diabetes wound healing via the physical cross-linking of graphene oxide-silver nanoparticles (GO-Ag NPs),chitosan (CS), and poly(N-isopropylacrylamide) (PNIPAM). The wound dressing possesses injectability, self-healing, favorable porosity, water absorption, moisture retention, adhesiveness, antibacterial and hemostatic functionalities. Moreover, the GACP@PRP hydrogel protects PRP to sustain growth factors release, promote cell proliferation and migration, which significantly accelerated wound healing rate in SD rats full-thickness skin defect model. Together with its great biocompatibility and biosafety, GACP@PRP meets the multiple functional requirements of diabetic wound dressing and is promising for clinical diabetic wounds management.
