Foodborne Escherichia coli is one of the health-threatening pathogens existing on the surface of vegetables and fruits. Although antibiotics are the first line of defence against bacteria, increasing concerns are awake about the multidrug resistance caused by overuse and misuse of antibiotics. Therefore, alternative antibacterials are urgently necessary. In this context, we identified, cloned and expressed a novel endolysin LysD6E derived from marine phage D6E for its potential antibacterial action against E. coli . LysD6E consists of an Amidase_3 domain belonging to the N-acetylmuramoyl-L-alanine amidase family. LysD6E was stabile between 4 and 70 °C, and pH between 6 and 10. It had strong lysogenic activity against E. coli and Salmonella typhi . Furthermore, when applying 0.5 μM of LysD6E together with 5 mM EDTA on lettuce for 2 h, viable counts of E. coli ATCC 25922 reduced by 2.05 Log CFU/mL. Our findings suggest that phage-derived LysD6E has the potential against foodborne E. coli in raw vegetables.

In lignin depolymerization, we use a lot of organic solvent which is still an environment problem in large scale industrialization. Therefore, we propose the photocatalytic biorefining green closed-loop (PBGC) to realize green and sustainable development. Different from organic solvents, we find that supramolecular solvents can synergistically interact with photocatalysts to influence the final products. The solubility of Alkali lignin (AL) in supramolecular solvent was 150 % higher than in ChCl/1,4 BDO (1:3) due to the AL and solvent have the similar supramolecular structure. Additionally, supramolecular solvent was used at low temperature (60 °C) which overcame the bottleneck of high viscosity provided huge possibility on industrial application. AL was photocatalytic-assisted oxidized by WO 3 /g-C 3 N 4 /h-BN (WCB). The conversion of AL achieves 38.61 wt%, and the yield of vanillic acid is 22.87 % in product. In this process, the β-O-4 bonds within the lignin structure were activated by hydroxyl radicals originating from the supramolecular solvent. The hydroxyl radical was produced from 1,4 BDO in supramolecular solvent. In dark environment, AL interacted with supramolecular solvent aroused the generation of C α aryloxy radical (ArO•). The superoxide radical was produced on the WCB from O 2 which could stabilize the C α ArO• quickly to final products.

Despite significant advancements in tumor immunotherapy, challenges including insufficient immunogenicity and immunosuppressive microenvironment continue to hinder therapeutic effect. The immunogenic cell death (ICD) enhances the tumor immune microenvironment and potentiate immunotherapy response. Certain chemotherapeutic agents can induce ICD; however, their limited immunogenicity, poor tumor-site targeting, and low tumor permeability restrict their efficacy. Herein, bacteria-driven liposomes were designed. Liposomes co-loaded with mitoxantrone (MTO) and iron ions (Fe 3+ ) were engineered to leverage the hypoxia-responsive properties of Escherichia coli Nissle 1917 (EcN) for precise tumor-site targeting. In the acidic tumor environment, mitoxantrone/ferric ions liposomes (LFM) released Fe 3+ and MTO. Intracellular Fe 3+ is reduced to Fe 2+ , catalyzing the Fenton reaction to generate reactive oxygen species (ROS) and induce ferroptosis. Concurrently, mitoxantrone (MTO) exerts direct cytotoxic effects on tumor cells. The synergistic interplay of these mechanisms significantly enhances the immunogenicity of tumor cells, triggering ICD and subsequently activating systemic antitumor immune responses. The drug delivery system constructed in this study integrated chemotherapy, ferroptosis, and immune activation, providing an innovative and effective strategy for tumor therapy. This approach paves the way for advanced combination therapies in cancer treatment.

Conventional oil-based microcapsules face critical limitations such as lubricant leakage and instability in humid environments, leading to diminished durability and performance. To overcome these challenges, this study develops a novel epoxy (EP) composite coating incorporating xylem fiber-wrapped polyacrylamide (XFP) organogel particles. The XFP organogel, synthesized via solvent co-absorption and physical isolation, encapsulates glycerol within a polyacrylamide matrix stabilized by xylem fibers. This design effectively retains glycerol within the matrix, enabling it to function as an internal lubricant that contributes to the formation of a stable lubricating film while minimizing premature dissolution in aqueous conditions. Tribological tests under dry friction revealed that the EP-XFP 25 coating (25 wt% XFP) reduced the friction coefficient (COF) by 77.3 % and wear rate by 77.5 % compared to pure EP, driven by glycerol lubrication and enhanced fiber flexibility. In simulated seawater, the EP-XFP 10 coating (10 wt% XFP) achieved a 53.4 % lower COF and 87.3 % reduced wear rate, benefiting from synergistic hydration lubrication and glycerol-seawater interactions. The XFP organogel exhibited robust thermal stability (< 120 °C) and anti-freezing properties (−40 °C), ensuring reliability in extreme environments. This work pioneers a sustainable, leakage-resistant self-lubricating coating, offering transformative potential for mechanical, marine, and aerospace applications requiring adaptive wear resistance.

Oxidizing glycerol to produce formate as a substitute for the traditional slow anodic oxygen evolution reaction is an effective strategy to enhance hydrogen production efficiency and reduce associated costs. However, the development of efficient and stable catalysts remains a significant challenge for the glycerol oxidation reaction coupled with water electrolysis. In this study, we synthesized molybdenum-doped Ni 3 Se 2 /NiSe nanomaterials supported on nickel foam using a straightforward one-step hydrothermal method. In a 1 M KOH solution, the Mo 0.2 catalyst exhibited exceptional electrocatalytic oxidation performance. Specifically, during the glycerol oxidation process, it achieved a current density of 10 mA cm −2 at a remarkably low potential of 1.20 V (vs. RHE) and demonstrated good electrochemical stability at a current density of 50 mA cm −2 . Studies indicate that the incorporation of molybdenum atoms modifies the chemical environment of nickel and selenium atoms, which not only enhances the electrocatalytic activity of the catalyst but also improves the stability of the material itself. Additionally, it facilitates the catalytic oxidation of glycerol at the anode while concurrently promoting hydrogen evolution at the cathode, resulting in the efficient simultaneous production of hydrogen and formate.

In our previous study (Electrocatalysis 15: 394–400, 2024), we proposed a method for preparing polymelamine (pMel) by adding a small amount of water to deep eutectic solvents (DES). However, electropolymerization under completely anhydrous conditions has not yet been achieved. This study experimentally identified that the main challenges in electropolymerizing melamine in anhydrous DES solutions are the low concentration of melamine monomer used in current literature and the slow diffusion rate in DES. These factors lead to the rapid depletion of melamine monomer in the electrode-solution interface diffusion layer by electro-generated active chlorine, ultimately preventing the effective deposition of pMel films. By leveraging the high solubility of melamine in DES, we successfully achieved pMel synthesis under anhydrous conditions in Ethaline and Glyceline by appropriately increasing the melamine monomer concentration or applying stirring. The formation process and morphological structure of the pMel deposition layer were confirmed using cyclic voltammetry (CV), quartz crystal microbalance (EQCM), and atomic force microscopy (AFM).

Baijiu plays an essential role in Chinese food culture, but there are still certain limitations in the identification of the aroma type and brand of Baijiu. In this study, based on the Tollen’s reagent, a colorimetric sensor array was constructed for aldehydes and Baijiu discrimination. In the presence of aldehydes or Baijiu, the silver ions (Ag + ) adsorbed by negatively charged nanoparticles can be reduced to elemental silver (Ag 0 ) in situ. Ag 0 deposited on the surface of gold or silver nanopaticle (Au NPs or Ag NPs) leading to the formation of Au@Ag or Ag@Ag core-shell structure which accompanied by a color change. We developed Tollen’s reagent-based sensor array shows the outstanding detection capability in discriminating and quantifying of aldehydes. On this basis, 16 kinds of Baijiu were also identified accurately, the visual results were verified by HCA and LDA models. The colorimetric sensor developed in this study is promising for aroma recognition and brand identification of Baijiu.

Lithium-sulfur batteries (LSBs) are poised to revolutionize next-generation energy storage due to their high energy density. However, the “polysulfide shuttle effect” poses a critical challenge to their cycling stability. Herein, we introduce a cation-deficient TiO 2 /polypyrrole (Ti 1-x O 2 /PPy) nanocomposite-modified polypropylene separator designed to mitigate this issue. This novel separator effectively captures and catalytically transforms polysulfides (LiPSs) during charge/discharge cycles, thereby enhancing LSB cycling stability. Notably, the modified separator enables an LSB to retain 708.8 mAh g −1 after 300 cycles at 0.5C and an impressive 554.1 mAh g −1 after 1000 cycles at 1C. Our findings not only present a promising approach to separator modification for LSBs but also offer critical insights into manipulating electrochemical reactions, potentially driving future improvements in LSB technology.

Magnesium phosphate cement (MPC) has attracted attention as a green coating material owing to its excellent adhesion and dense structure. However, MPC's natural hydrophilicity and poor water stability make it susceptible to infiltration by water containing harmful ions, limiting its application as a coating material. This study investigates the effect of polydimethylsiloxane (PDMS) on the wettability of MPC coatings with hierarchical structures. The chemical functional groups and surface morphologies of PDMS-modified MPC coatings were analyzed. The surface free energy of MPC surface was evaluated to understand the physicochemical properties of MPC surface. Static contact angles of MPC coatings with varying PDMS contents were measured using four polar and non-polar liquids. The most important and widely used models were applied to calculate the surface free energy of MPC coatings, assessing the suitability of each model. Wetting envelopes were constructed for the various surfaces to predict the wettability of the MPC with commonly employed liquids. The results indicate that the addition of PDMS successfully transformed MPC from hydrophilic to highly hydrophobic. The improvement in water repellency is due to the cross-linking reaction between PDMS and MPC, which lowers the surface energy through chemical modification. Additionally, the formation of hierarchical structures increases surface roughness, further improving hydrophobicity. Envelope curves were successfully designed to predict the wettability of the coating across a large range of liquids.

The application of gelatin (GEL)-based films in food packaging is limited by poor mechanical strength, high water sensitivity, low gas barrier properties, and lack of antibacterial activity. In this study, dialdehyde starch (DS) and AgNPs-immobilized MXene nanosheets (AgNPs@MXene) were incorporated into GEL to fabricate active packaging films. The strong interfacial interactions and compact structure significantly enhanced the films' physicochemical properties. Compared with pure GEL, the GEL/DS/AgNPs@MXene-5 film showed a 96.33 % increase in tensile strength, a 391.59 % increase in elongation at break, and reductions of 62.33 %, 71.62 %, and 71.13 % in water solubility, water vapor, and oxygen permeability, respectively. Additionally, it exhibited >90 % antibacterial activity against S. aureus and E. coli , attributed to the synergistic effect of AgNPs and photothermal MXene, while maintaining good biosafety and biodegradability. Packaging tests confirmed its effectiveness in preserving the post-harvest quality of Tricholoma matsutake and maintaining pork freshness, demonstrating great potential for active food packaging.

Lamellar liquid crystals (LLCs) exhibit significant potential in lubrication due to their unique layered structure. Introducing ionic liquids (ILs) to enhance the lubrication performance of the LLCs is a feasible approach. However, common ILs often demonstrate substantial corrosivity toward metals. In this study, LLCs were formed using oleic acid (OA) as the anion, alcoholamine solvents with corrosion-resistant properties (including monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA)) as the cation, and glycerol (GL) as the solvent. The results reveal that the synergistic effect between the physical adsorption film and the tribochemical reaction film during friction significantly improves their lubricating performance. Notably, the OA/GL/MEA system outperforms OA/GL/DEA and OA/GL/TEA in lubrication properties, which can be attributed to its tighter intermolecular arrangement and smaller interlayer spacing, thereby providing enhanced mechanical strength. Furthermore, the ionic liquid-based LLCs exhibit negligible corrosiveness to steel, owing to the presence of carboxylic acid groups, unsaturated bonds, and hydroxyl groups in the molecular structure, which strengthen ILs adsorption on metal surfaces. Their combined lubrication efficacy and corrosion resistance render these LLCs highly promising for mechanical lubrication applications.

The physicochemical properties, hydrogen-bonding networks, and freezing and thawing behaviors of betaine-based NADESs were investigated in this study. Results showed that the NADESs with moderate acidity (pH 6.66–8.10) are suitable for meat and aquatic products and their mild antioxidant activities may reduce the oxidative damage of frozen foods during cryopreservation. Moreover, the hydrogen bond networks in NADESs weaken with higher water content but strengthen at lower temperatures. The NADES possesses a more potent antifreeze property compared to water and sucrose, remaining unfrozen even at −80 °C. Furthermore, the presence of NADESs can mitigate the formation and growth of ice nucleation and suppress the recrystallization process. Additionally, the thawing time can be shortened by 2–4 times with the assistance of NADESs when compared with the water. The simultaneous effects of NADESs during freezing, storage and thawing stages can provides extensive cryoprotection. Applications in frozen shrimp surimi further announced the potentials of NADESs as cryoprotectants for the frozen food industry.
