In this study, a ternary complex was prepared using soybean protein isolate (SPI), (−)-epigallocatechin gallate (EGCG), and exopolysaccharides (EPS) produced by Lacticplantibacillus plantarum A114. It systematically evaluated the stabilization on W 1 /O/W 2 emulsions and protective effects on the encapsulated L. plantarum A114 upon long-term storage, pasteurization, and in vitro simulated gastrointestinal digestion. The physical stability and microstructure of the emulsions were analyzed by particle size, ζ-potential, creaming index, and rheological behaviors. The survival rate of the strain was determined by flow cytometry during 28-day of storage (4 °C), after pasteurization and in vitro simulated gastrointestinal digestion to assess their protective efficacy. The results showed that compared with the emulsions stabilized by native SPI, (EGCG-SPI)-EPS stabilized emulsion was with the smallest particle size and the lowest degree of emulsion separation during 28-day storage period, and the survival rate of L. plantarum A114 increased by 1.23 times during storage, 0.88 times after pasteurization, and 1.45 times after in vitro simulated gastrointestinal digestion. These results suggested that the emulsions stabilized by (EGCG-SPI)-EPS complex exhibited superior physical stability and protective effects on encapsulated strains. In addition, this study further observed the microstructure of the strains encapsulated in the emulsion stabilized by different complex using confocal laser scanning microscopy (CLSM). The results indicated that the introduction of EGCG and EPS could construct a composite interface layer with stronger physical barriers and antioxidant protection through the synergistic effect with SPI, thereby significantly improving the stability of W 1 /O/W 2 emulsion system and the protective effect on L. plantarum A114. To sum up, the (EGCG-SPI)-EPS ternary complex presented the best protective synergistic effect and was an extremely promising targeted delivery system for probiotics. This study has important guiding significance for the development of probiotic functional foods with high survival rates.

Transition metal oxyhydroxides are crucial for the electrochemical oxidation of 5-hydroxymethylfurfural (HMF), though the co-adsorption and activation mechanisms of HMF and hydroxyl species require further clarification. This study designs cerium-doped Co-based layered double hydroxide (LDH) arrays, including 3%Ce-Co 3 Fe 1− x Al x -LDH/NF, to investigate Fe as a secondary active center and the role of Ce–O–TM (Transition metal) bridges in regulating HMF/OH − adsorption. Theoretical calculations indicate that Ce–O–TM bridges induce f – p – d gradient orbital coupling, optimizing HMF/OH − adsorption configurations and facilitating the HMF oxidation reaction (HMFOR). Synchrotron radiation characterization and in situ Raman spectroscopy reveal that Fe enhances electronic interaction between Ce and Co/Fe sites, strengthening the stability of M–O bonds, suppressing metal dissolution, and further optimizing reactant adsorption. Fe doping also modulates charge distribution and accelerates charge transfer. The optimized 3%Ce-Co 3 Fe 1 -LDH/NF delivers industrial current density (0.1 A cm −2 ) at 1.44 V RHE , with 98.1% HMF conversion, 99.6% FDCA yield, and 99.8% Faradaic efficiency. In an anion exchange membrane (AEM) electrolyzer, it achieves 0.5 A cm −2 at 2.1 V while maintaining high stability across 0.1–0.5 A cm −2 . These results provide an effective strategy for designing high-performance HMFOR catalysts through electronic structure modulation.

The rational design of biomass-derived carbon aerogels is crucial for developing high-energy-density supercapacitors. Herein, we report a one-pot synthesis of in situ N/O dual-doped porous carbon aerogels from cotton fibers, utilizing a NaOH/urea aqueous system as a multifunctional solvent, followed by freeze-drying and carbonization. The optimized cotton fiber-derived carbon aerogel (HCFA-600) possesses a high specific surface area (398.4 m 2 g −1 ), a honeycomb-like pore architecture, and significant heteroatom doping. When tested in a three-electrode system, the HCFA-600 electrode achieves a notable specific capacitance of 249 F g −1 at 1 A g −1 . A symmetric coin-type supercapacitor (HCFA-600//HCFA-600) assembled using this material delivers a high energy density of 14.5 Wh kg −1 at a power density of 500 W kg −1 , while retaining 75.58% of its initial capacitance after 5,000 cycles at 5 A g −1 . The proposed synthesis route, which enables in situ heteroatom doping of porous carbon aerogels from renewable cotton fibers, is not only simple, eco-friendly, and cost-effective but also holds promising potential for application in high-performance supercapacitors.

Transition-metal-based catalysts with asymmetric coordination structures are promising candidates for industrial oxygen evolution reactions. However, the large-scale synthesis of catalysts with precisely constructed asymmetric coordination structures is still challenging. Herein, we developed an industry-compatible roll-to-roll combustion technology to synthesize NiFc–MOFs with reasonably constructed asymmetric Fe–O–Ni coordination. Owing to the modulated electronic spin states, regulated adsorption configurations of oxygen-containing intermediates, and charge redistribution, the as-prepared NiFc–MOF achieved ultralow overpotentials of 196 mV and 257 mV at η10 and η1000, respectively. The long-term stability evaluation of catalysts in a three-electrode system demonstrates excellent durability of 2000 h at 2 A cm–2. Further, the assembled anion exchange membrane water electrolyzer (AEMWE, NiFc–MOF||R–Ni) operated at a current density of 1 A cm–2 achieved high overall water splitting with a low cell voltage of merely 2 V and maintained outstanding durability for over 500 h under ambient atmosphere. More importantly, the NiFc–MOF maintained high stability for over 250 h at 1 A cm–2 in simulated seawater. This study offers a reliable pathway to the large-scale synthesis of low-cost NiFe-based catalysts for ampere-level oxygen evolution in both pure and seawater.

This work regulates electronic structure and oxygen vacancies of Fe 2 O 3 via Nd-O-Fe 4f-2p-3d orbital coupling, promoting OER mechanism from AEM to LOM and clarifying the intrinsic catalytic origin. • The as-prepared Nd-Fe 2 O 3 @C shows low overpotential and favorable OER activity, with stable operation over 300 h at 10 mA cm -2 , presenting remarkably improved stability. • In-situ IR, in-situ Raman combined with DFT calculations demonstrate that Nd doping upshifts the Fe d-band center and reduces the Fe spin state, significantly lowing the adsorption energy of Fe 2 O 3 toward *OH and *O species. The development of highly active and stable non-precious metal-based catalysts for the oxygen evolution reaction (OER) is crucial for achieving efficient and low-cost hydrogen production through electrolysis. Herein, the temperature-programmed calcination approach is employed to synthesize the target catalyst of Nd-doped Fe 2 O 3 on graphitic carbon (Nd-Fe 2 O 3 @C). This Nd-Fe 2 O 3 @C presents excellent OER performance with a low overpotential of 359 mV at 10 mA cm −2 , a small Tafel slope of 70.31 mV/dec, and long-term stability (over 300 h). Tetramethylammonium hydroxide (TMAOH) measurements coupled with in-situ characterizations capture the dynamic evolution of key oxygen intermediates, verifying that Nd doping creates oxygen vacancies and thereby triggers the lattice oxygen oxidation mechanism (LOM). Density functional theory (DFT) calculations revealed that Nd doping increases antibonding orbital occupancy, which leading to weaker adsorption of oxygen intermediates and facilitate *OH and *O desorption during the OER. This work establishes oxygen vacancy engineering as effective strategy for robust water oxidation through LOM pathway. The Nd-Fe 2 O 3 @C with 4f–2p–3d gradient orbital coupling catalyst exhibits a low overpotential (η 10 = 359 mV), a small Tafel slope (70.31 mV dec -1 ) and outstanding long-term catalytic stability (300 h). DFT calculations demonstrate that Nd doping upshifts the Fe d-band center and reduces the Fe spin state, significantly lowing the adsorption energy of Fe 2 O 3 toward *OH and *O species.

Water-in-oil-in-water (W1/O/W2) emulsions are capable of co-encapsulating hydrophilic and hydrophobic compounds, but their practical application is often limited by poor physicochemical stability. In this study, a W1/O/W2 emulsion was developed by stabilizing the internal and external aqueous phases with chitosan (CS) and whey protein concentrate (WPC), respectively, while incorporating cinnamaldehyde (CA) into the intermediate oil phase for potential dual-interface stabilization through interfacial interactions. Optimization of the phase composition led to an emulsion with significantly improved storage stability (extending its shelf-life from 7 to 60 days) and enhanced tolerance ability against pH and ionic strength variations. The optimized emulsion successfully co-encapsulated tea polyphenols (TPPs) and β-carotene (BC), maintaining high bioactive compound levels and preserving antioxidant activity under varying pH and thermal conditions. In vitro gastrointestinal digestion assays revealed that CA-modified emulsions significantly improved the bioaccessibility of TPPs and BC to 61.72% and 48.72%, respectively, corresponding to approximately 3.1-fold and 2.0-fold increase compared to their free form. Moreover, the co-encapsulation system exhibited higher antioxidant capacity. This study provides a promising strategy for improving the stability and co-delivery performance of hydrophilic and lipophilic bioactive compounds, with potential applications in development of functional and value-added foods.

Sialic acid (Neu5Ac) possesses a wide range of bioactivities; however, its instability under acidic conditions prevents it from effectively reaching the intestine. This underscores the urgent need to develop a stable delivery system capable of protecting Neu5Ac from gastric degradation and achieving its controlled release in the intestine. To enhance the stability and achieve controlled release, Neu5Ac was encapsulated within water-in-oil-in-water (W1/O/W2) emulsion-based microcapsules in this work. S2 emulsions featured a “dual-chamber, tri-phase” structure, comprising a Neu5Ac-chitosan fluid gel (inner aqueous phase), maize oil (oil phase), and an external aqueous phase of 13% sodium starch octenyl succinate, 5% β-cyclodextrin, 1.5% sodium caseinate, and 0.5% carboxymethyl cellulose. Microstructural analyses confirmed spherical morphology with core-shell architecture and bimodal droplet distribution (1-10 μm). In addition, S2 emulsions exhibited an encapsulation efficiency (EE) of 92.44%, a zeta potential of −60.80 mV, a Sauter mean diameter (d 3 , 2 ) of 1.337 μm, shear-thinning behavior and weak gel network stability. S2 emulsions were spray-dried to obtain S2 microcapsules. S2 microcapsules exhibited an EE of 89.43% and a d 3 , 2 of 3.839 μm, while FT-IR and XRD verified physical encapsulation without covalent bonding. In vitro digestion, S2 microcapsules exhibited controlled release behavior during simulated intestinal digestion, with a Neu5Ac release rate of 85.61% after 120 min. In mice, microencapsulated Neu5Ac increased the relative abundance of Akkermansia , Lactobacillus , and Bifidobacterium . This system demonstrates promising potential for the co-delivery and controlled release of Neu5Ac, and shows great promise for expanding its applications in the food industry.

The development of Ru-based electrocatalysts with superior activity and stability for proton exchange membrane water oxidation remains a significant challenge. A key strategy is the precise engineering of the lanthanide–O–Ru structure to tailor surface species and continuously modulate Ru–O covalency, thereby optimizing the adsorption energy of intermediate species for enhanced catalytic performance. In this study, density functional theory (DFT) calculations predict that incorporating the late lanthanides (Tm–O–Ru) into the RuO2 structure significantly enhances the density of states near the Fermi level to a greater extent than the middle lanthanide (Gd–O–Ru). This leads to a lower energy barrier for *OOH as the rate-determining step of the oxygen evolution reaction (OER). Additionally, the strength of *OH adsorption follows the Tm–O–Ru > Gd–O–Ru > RuO2 trend. Experimental results confirm the theoretical predictions: Tm–O–Ru structure enhances the Ru–O covalency, tunes the electronic structure of Ru, and optimizes *OH adsorption. These modifications result in good OER performance with an overpotential of 201 mV and robust stability over 1000 h at 10 mA cm–2. Furthermore, a Tm–RuO2-based PEMWE device stably operates at 100 mA cm–2 for 200 h with a low degradation rate of 0.195 mV h–1, outperforming most Ru-based catalysts reported in the literature.

Antibiotics like doxorubicin hydrochloride (DOX) are widely used in medicine, but their environmental residues pose risks to human health and ecosystems. This study optimized the synthesis of C-Fe₃O₄@ZIF-8 composites using response surface methodology (RSM) to enhance DOX release efficiency, thereby mitigating environmental antibiotic contamination. Under optimized conditions (37 °C, pH 5.0), the C-Fe₃O₄@ZIF-8 composite achieved a significant increase in cumulative DOX release, from 40.8% to 61.1%. The pH-responsive release further validated the optimization strategy. Characterization via scanning electron microscopy (SEM) and X-ray diffraction (XRD) revealed a structural transformation from rhombic dodecahedral crystals to more stable spherical particles with enhanced crystallinity. Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) confirmed an increase in surface-active sites and oxygen-containing functional groups, contributing to improved drug release efficiency. These findings provide valuable insights into optimizing C-Fe₃O₄@ZIF-8 for drug delivery, advancing environmentally friendly antibiotic management strategies.

Section
Background
Pancreatic cancer is highly lethal, and METTL3 plays a crucial role in the regulation of m6A. However, the therapeutic potential of METTL3 in pancreatic cancer is unclear.
Section
Methods
By means of functional gain and loss experiments, the relationship between METTL3 and gemcitabine resistance as well as ferroptosis was explored. The target genes of METTL3 were screened, and the influence of O-GlcNAcylation on the stability and ubiquitination modification of METTL3 was dissected.
Section
Results
We found that METTL3 is highly expressed in pancreatic cancer and regulates ferroptosis and gemcitabine resistance by promoting the degradation of HMGB1 in an m6A-YTHDF2-dependent manner. O-GlcNAcylation modulates the METTL3’s stability. The interaction between the deubiquitinase EIF3H and METTL3 is influenced by O-GlcNAcylation.
Section
Conclusion
METTL3 affects pancreatic cancer progression by promoting degradation of HMGB1. The O-GlcNAcylation of METTL3 not only stabilizes METTL3 but also augments EIF3H-mediated deubiquitination. These findings uncover potential mechanisms underlying gemcitabine resistance in pancreatic cancer and offer potential therapeutic strategies for the treatment of this disease.

High-entropy oxides (HEOs) represent promising anode materials for lithium-ion batteries, yet understanding the intricate relationship between their multi-element composition, crystal structure, and lithium storage mechanism remains a fundamental challenge. This study systematically investigates this relationship in (XCoNiCuZn)O (X = Li, Na, Mg) HEOs by modulating the fifth element. While all compositions form a single rock-salt structure, the cationic radius and valence state of X dictate both the lattice parameters and the electrochemical reaction pathway. It is revealed that (LiCoNiCuZn)O and (MgCoNiCuZn)O undergo a conversion-dominated phase transition mechanism, whereas (NaCoNiCuZn)O follows a solid-solution reaction. This mechanistic divergence, elucidated through in-situ EIS, ex-situ XRD/XPS, and kinetic analysis, directly governs the electrochemical performance. The Li-based HEOs (LiCoNiCuZn)O demonstrates exceptional performance, delivering a high capacity of 549.7 mAh g −1 with 83.4% retention after 300 cycles at 0.5 A g −1 , attributable to its effective charge compensation and superior ion conductivity. This work establishes a clear correlation from cationic modulation to storage performance, offering critical guidance for the rational design of HEOs for energy storage.

Bismuth oxide (Bi 2 O 3 ) is widely used in photocatalytic oxidation degradation of organic pollutants due to its simple composition, green environmental protection and stable structure. However, the limited specific surface area (SSA) and the slow charge kinetics significantly limit its photocatalytic ability. Here, Bi 2 O 3 /MWCNTs heterojunctions were synthesized using hydroxylated multi-walled carbon nanotubes (MWCNTs-OH) as the substrate, explore the crystal growth mechanism and apply it to photocatalytic oxidation reactions. The one-dimensional (1D) structure and excellent electrical conductivity of MWCNTs-OH provide a special transport path for the spatial separation of photogenerated electrons and holes. The stable chemical properties and unique hollow cavity structure of MWCNTs-OH significantly increase the specific surface area of Bi 2 O 3 /CNTs. The optimized Bi 2 O 3 /CNT-3 demonstrated outstanding performance in the photocatalytic oxidation degradation of organic substances such as lignin and RhB. The photocatalytic activity of lignin degradation under visible light has increased by 5.8 times, and the performance of RhB removal has increased by 6.7 times.
