In the field of food colloid systems, elucidating the synergistic stabilization mechanism of composite emulsifiers at the interface in Pickering emulsions is crucial for designing high-performance emulsions. This study investigates the synergistic stabilization mechanism of β-cyclodextrin (β-CD) and Tween 60 in Pickering emulsions using experiments and dissipative particle dynamics (DPD) simulations. The optimal mixing ratio (β-CD: Tween 60 = 1:3) achieves the lowest oil–water interfacial tension (5.38 ± 0.06 mN/m) and the smallest rearrangement rate constant (K r ). All systems exhibit contact angles below 90°, forming oil-in-water emulsions. DPD simulations reveal that at the 1:3 ratio, β-CD and Tween 60 form a uniform, dense interfacial film on oil droplets. Radial distribution function analysis indicates strong short-range interactions between the two emulsifiers. The relative concentration profiles show that at this ratio, the peaks of the β-CD and Tween 60 curves are highly consistent, and the interfacial arrangement is the most ordered, confirming the mechanism of dense film formation through synergistic adsorption. Excess β-CD promotes self-aggregation, disrupting the synergistic structure. This work provides a theoretical foundation for designing high-performance Pickering emulsions.

Gallic acid (GA) chelates with exposed metal active sites of Ni/Co-DABD MOF, effectively protecting metal ions and elevating MOF coordination stability. • The GA-modified Ni/Co-DABD MOF@NH₂-MXene composite electrode delivers a high specific capacitance of 2044 F g -1 at 1 A g -1 with superior rate capability and cycling durability. • GA modification strengthens the interfacial synergy between MOF and NH₂-MXene, significantly boosting charge transfer efficiency and structural stability of the composite. The limited active sites and poor electrochemical structural stability of metal-organic frameworks (MOF) severely limit their application in electrochemical energy storage. In this study, we used the acid properties of gallic acid (GA) as an etching agent to etch MOF surface active sites. Subsequently, the protonated GA is further chelated with the exposed metal active site, which can effectively protect the metal ions. At the same time, GA provides a large number of phenolic hydroxyl groups, which greatly improves the coordination stability of MOF. A new MOF@MXene composite electrode material was obtained by solvothermal synthesis of GA-modified MOF and aminated MXene. The electrochemical test results show that the new MOF@MXene composite electrode material synthesized by this scheme has high specific capacitance and high rate stability. The functional modification of MOF by GA greatly improves the synergistic binding performance between MOF and MXene, and thus significantly improves the electrochemical stability of composite electrode materials. The mechanism of the electrochemical reaction was investigated by in-situ X-ray diffraction and theoretical calculation. In this paper, the functional mechanism of polyphenols on MOF is described, which provides a new idea for the electrochemical application of MOF. The GA-modified Ni/Co-DABD MOF@NH₂-MXene composite electrode delivers a high specific capacitance of 2044 F g -1 at 1 A g -1 with superior rate capability and cycling durability.

Developing high-efficiency and stable catalysts for NaBH 4 hydrolysis is critical for safe, high-density and on-demand hydrogen generation. Herein, a core-shell structured Co@SiO 2 @C composite was fabricated as support to immobilize Ru nanoparticles, which precisely regulates electron-metal-support interactions (EMSI). The SiO 2 layer inhibits Ru aggregation and carbon layer accelerates electron transfer, synergistically optimizing Ru electron density and boosting Co–Ru dual active sites. The composite catalyst Co@SiO 2 @C–Ru exhibits significantly enhanced catalytic performance, achieving a hydrogen production rate of 7783.2 mL min −1 g −1 at 25 °C, substantially surpassing most previously reported catalysts. Furthermore, the catalyst retains excellent catalytic activity after five cycles, demonstrating favorable structural and performance stability. Mechanism studies confirm that EMSI drives electron transfer from Co to Ru, optimizing BH 4 – adsorption and activation via Michaelis–Menten kinetics. This work offers a facile strategy for constructing high-performance dual-metal core-shell hydrolysis catalysts.

Silver is an extensively investigated electrode material for electrochemical CO 2 reduction owing to its high electrical conductivity and structural stability. However, a key limitation of silver catalysts is their weak adsorption of the *CO intermediate. This intrinsic constraint restricts the reaction primarily to two-electron pathways, hindering the formation of multi-electron products. Here we demonstrate that surface molecular modification can address this limitation. By anchoring bromothymol blue molecules onto the silver surface, we engineer a localized hydrogen-bonding network that stabilizes *CO intermediates via O···H–O interactions, prolonging their surface residence time. In situ spectroscopy and theoretical simulations reveal that this local microenvironment thermodynamically stabilizes *CO against desorption while kinetically facilitating its subsequent hydrogenation and C-C coupling. Consequently, the retained *CO undergoes deeper reduction pathways, generating CH 4 , C 2 H 4 , C 2 H 5 OH, and CH 3 COOH. At a current density of 400 mA cm −2 , the Faradaic efficiency for multi-electron products reaches 24.2%. This work shifts the design paradigm from metal-centric electronic tuning to local microenvironment engineering, offering an alternative strategy for enabling multi-electron transfer on non-copper catalysts.

Microplastic-oil co-contaminants have raised high environmental concerns due to their persistence and synergistic toxicity. However, conventional separation membranes, typically designed for single-pollutant removal, are ineffective against such complex systems. Moreover, the strong interfacial interactions between microplastics and oil promote aggregate formation, leading to severe membrane fouling and compromised separation performance. Herein, we present a robust, antifouling, and superhydrophilic membrane fabricated via sodium periodate-assisted co-deposition of caffeic acid and ε-polylysine for simultaneously removing both oil droplets and microplastic particles from contaminated water. The resulting caffeic acid/ε-polylysine composite superhydrophilic membrane achieves an impressive separation efficacy for various oil-in-water emulsions and polystyrene microplastics of different sizes. Notably, it exhibits superior separation performance for challenging microplastic-oil co-contaminants, with rejection of 99.89% for oil and 96.99% for 100-nm polystyrene microplastics over 300-min continuous filtration. It also sustains a high flux recovery, reflecting robust antifouling properties and thus highlighting a great potential for practical application in complex wastewater treatment. Additionally, the membrane shows a remarkable antibacterial activity even after 30 days of immersion. This study demonstrates a scalable and sustainable strategy for fabricating high-performance polyphenol-based antifouling membranes, offering an effective solution to manage these emerging co-contaminants.

Aloe-emodin (AE), a natural photosensitizer, suffers from poor aqueous solubility that limits its photodynamic efficacy. This study developed a novel food-friendly co-amorphous system using ferulic acid (FA) as a co-former to enhance AE’s solubility and photodynamic performance. The AE-FA co-amorphous mixture was characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), and Fourier-transform infrared spectroscopy (FTIR) with molecular dynamics simulations confirming hydrogen bond formation. Results demonstrated that this complexation effectively reduced the lattice energy of AE, leading to significantly improved solubility and physical stability of the CAM system. Furthermore, AE-FA CAM exhibited enhanced antimicrobial photodynamic activity against Staphylococcus aureus compared to pure AE, which was attributed to reduced molecular agglomeration and alleviated fluorescence quenching. This study aims to develop a novel, food-friendly co-amorphous system to simultaneously enhance the solubility and photodynamic efficacy of AE. This work presents the first report of a co-amorphous system between AE and FA specifically designed for photodynamic applications, providing an effective strategy to overcome solubility limitations of natural photosensitizers in food safety applications.

Decoupling electronic and phononic transport requires nanoscale control over scattering landscapes. Here, we show that direct ink writing generates a hierarchical nanoarchitecture in Bi 2 Te 3 , which comprises nanopores (10-150 nm), amorphous-crystalline nanointerfaces, and dense grain boundary networks that suppress lattice thermal conductivity by around 50% from ∼0.6 W m −1 K −1 to ∼0.3 W m −1 K −1 , as quantitatively confirmed by Debye-Callaway modeling. Sb/Te/Se co-enrichment (Sb/Te co-enrichment was applied to the p -type BST system, while Te/Se co-enrichment was applied to the n -type BTS system) refines this nanopore distribution while driving atomic-scale intercalation of Sb/Te enrichment between quintuple layers, as directly visualized by atomic-resolution STEM-EDS, bridging van der Waals gaps to selectively restore electrical conductivity without compromising phonon scattering. The optimized p -type and n -type materials achieve peak ZT values of 0.87 (303 K) and 0.89 (423 K), respectively, which exceed commercial Bi 2 Te 3 performance. Single-leg generators deliver conversion efficiencies of 3.51% and 2.53%, ranking among the highest for additively manufactured thermoelectrics. This work demonstrates that process-generated nanoarchitectures, combined with atomic-scale compositional engineering, enable effective phonon–electron decoupling in printed thermoelectric materials.

A series of La 2 O 3 -Ga 2 O 3 -0.08Eu 2 O 3 - x Dy 2 O 3 amorphous samples ( x = 0–0.14, interval of 0.01) were synthesized via containerless solidification. XRD results demonstrated that the prepared materials possessed an amorphous structure with a broad diffraction hump instead of sharp crystalline peaks. Differential thermal analysis (DTA) revealed that Dy 2 O 3 doping barely altered the glass transition temperature ( T g ) but significantly increased thermal stability and crystallization characteristic temperature ( T x ) and thermal stability parameter Δ T ( T x - T g ), with the maximum Δ T reaching ∼96 °C at x = 0.09. Concentration quenching of Dy 3+ was dominated by multipolar interaction, confirmed by a critical distance ( R c ) of 18.98 Å and Dexter theory analysis. The optical band gap ( E opt ) remained ∼3.72 eV at x ≤ 0.06 and decreased to ∼3.42 eV at x = 0.11. CIE standard 1931 chromaticity coordinate values together with correlated color temperature (CCT) were tunable, with emission color evolving from warm reddish-orange to orange-yellow (CCT: 2250–3240 K). The excellent thermal stability, tunable PL, and tunable CCT render these amorphous materials promising candidates for solid-state luminescent devices.

C-lignin, a natural biopolymer of caffeyl alcohol subunits linked by benzodioxane motifs, is an ideal feedstock for direct catechol production. However, its hydrogenolysis is hindered by the high bond dissociation energies and steric congestion of vicinal C–O bonds in benzodioxane structures. Here, we report a low-loaded Co–Zn dual single-atom catalyst (Co SA –Zn SA @NC) that enables efficient C-lignin hydrogenolysis, achieving 84.6% catechol yield, 82% selectivity toward 4-propylcatechol, and a turnover number five times higher than precious Ru/C, attributing to the synergistic effect of the dual atomic sites. The major product, 4-propylcatechol, can be readily purified and upgraded into diverse value-added molecules. Mechanistic investigations reveal that the Zn and Co species, acting as the directing and active centers, respectively, synergistically drive the quasi-concerted cleavage of the vicinal C–O bonds. This work presents an atomically dispersed non-precious metal catalyst for C-lignin hydrogenolysis, providing a sustainable route to well-defined aromatics.

Developing low-cost, corrosion-resistant catalytic electrodes for the oxygen evolution reaction (OER) is essential for efficient and durable hydrogen production via anion exchange membrane water electrolysis (AEMWE). Herein, we report a polydopamine (PDA)-coated Fe,Cr codoped NiS2 self-supporting electrode (PDA-Fe,Cr-NiS2@NF). The nitrogen-rich functional groups of PDA establish robust M-N coordination bonds with active metal centers, thereby suppressing metal dissolution during anodic reconstruction. In parallel, the conductive PDA layer regulates interfacial electron redistribution and optimizes the hydrogen-bond network of interfacial water, lowering the OER activation energy. Its conformal protective layer further enhances catalyst stability. The optimized electrode delivers an OER overpotential of only 247 mV at 1 A cm–2. When integrated as the anode with a PtNiC cathode in an AEMWE cell, the system reaches a current density of 1 A cm–2 at only 1.737 V at 70 °C and operates stably for 1000 h, with a voltage decay rate of only 0.1 mV h–1, an electrolysis efficiency of 71.96%, and an energy consumption of 4.157 kWh Nm3– H2. This work establishes a viable coordination-protection strategy for constructing durable, high-performance OER electrodes for industrial-scale water electrolysis.

Arsenic (As) and polycyclic aromatic hydrocarbons (PAHs) frequently co-occur in industrial soils and act as persistent stressors that reshape soil ecological processes. However, it remains unclear how long-term As–PAH co-contamination influences pollutant redistribution, microbial community organization, and microbial functional allocation under chronic stress. In this study, gravity-driven soil column systems were established to simulate PAH contamination (30 mg/kg) with different As levels (0, 300, and 600 mg/kg) and operated continuously for 270 days. Long-term co-contamination altered the soil-profile redistribution of both PAHs and As. Compared with the PAHs-only treatment, co-contaminated treatments showed greater retention of PAHs in deeper soil layers (>30 cm), while As underwent pronounced vertical redistribution and a progressive shift toward As(V)-dominated profiles during prolonged incubation. Microbial community analysis showed that co-contamination reduced microbial abundance, strengthened deterministic community assembly, and increased network size, connectivity, clustering, and robustness. The dominant genus shifted from Micrococcaceae _unclassified in the PAHs-only treatment to Rhodococcus in the co-contaminated treatments, indicating selection toward more stress-tolerant and contaminant-responsive taxa. Metagenomic analysis further showed coordinated enrichment of stress-response genes, As metabolism genes, and PAH degradation genes, especially under high As loading. These results indicate that long-term As–PAH co-contamination acts as a profile-scale ecological filter that reshapes soil microbial communities and redirects microbial functional allocation toward stress tolerance, detoxification, and contaminant-associated metabolism.

Conventional supported Cu catalysts for the reverse water-gas shift (RWGS) reaction suffer from activity-selectivity trade-offs and stability issues. Herein, we report a carrier-free Cu catalyst (bio-Cu) synthesized via a pollen-templated strategy. The template creates a hierarchical porous framework and enables in situ carbon doping (~4 wt%), ensuring homogeneous Cu dispersion and inhibiting agglomeration. In the RWGS reaction, the bio-Cu catalyst exhibits outstanding performance, achieving >99.1% CO selectivity with 25.3% CO 2 conversion at 340°C and 3 MPa, approximately 3.2 times higher than a conventional Cu benchmark. Under ambient pressure at 450°C, it maintains 30.5% conversion with 99.99% CO selectivity and shows exceptional stability over 100 h. Mechanistic studies reveal that carbon doping generates electron-deficient Cu δ+ species and promotes a synergistic carbon cycle that operates alongside the conventional redox pathway, collectively enhancing the catalytic efficiency. This work provides new insights into the rational design of high-performance, carrier-free CO 2 hydrogenation catalysts.
