The 5-hydroxymethylfurfural electrooxidation reaction (HMFOR) stands out due to the value-added production and mild conditions. However, its catalytic efficiency is hampered by sluggish kinetics. Herein, with a focus on optimizing the adsorption and activation of reaction molecules, a Co 5.47 N-W 5 N 4 heterostructure catalyst is constructed for efficient HMFOR. The heterogeneous interface formed between Co 5.47 N and W 5 N 4 synergistically enhances the adsorption and activation of substrate molecules through electronic structure modulation and dual-site hydrogen bonding interactions. Meanwhile, the interfacial electron transfer from Co 5.47 N to W 5 N 4 facilitates the formation of high-valent cobalt species (Co 3+ /Co 4+ ), which is critical for activating formyl and hydroxymethyl groups. Furthermore, the hierarchical nanoparticle-nanosheet architecture provides abundant active sites while promoting efficient mass transport. These combined effects render Co 5.47 N-W 5 N 4 with enhanced HMFOR performance, along with a 5.80-fold increase in the rate constant for the rate-determining step. This work puts forward an approach for developing efficient HMFOR catalysts by promoting the adsorption and activation of reaction molecules.

The genusCitrusconsists of Tangerines (Citrus × reticulata), Mandarins (Citrus × reticulata), Oranges (Citrus × sinensis), Grapefruits (Citrus maxima), Lemons (Citrus × limon), and other citrus fruits. This study investigated the effects of 74 different citrus species and harvesting time on the quality of citrus dark tea using Hubei green brick tea as the raw material. Oranges (Citrus × sinensis) were found to outperform other species in improving the quality of citrus dark tea. Additionally, the impact of orange harvesting time (August to December) on the quality of orange dark tea was investigated by using the Peach leaf orange with the highest sensory score as the subject of the study. Results revealed that harvesting time can considerably impact the flavor quality of orange dark tea, but not its infusion color or scent. Specifically, the orange dark tea processed with September-harvested Peach leaf orange exhibited a strong fruity scent, a sweet and smooth flavor, and a harmonious tea and fruit aroma. With the delay of harvesting time, a downtrend was observed in the content of soluble proteins, flavonoids, hesperidin, synephrine, and limonin, as well as total volatile components, with the largest decrease in synephrine and flavonoids. However, the polysaccharide content increased in the peel of Peach leaf orange. Functional analysis revealed that the delay of harvesting time can diminish the inhibitory capacity of orange-dark tea on α-glucosidase and α-amylase. Organoleptic quality and physiological activity analysis demonstrated September as the optimal time for harvesting Peach leaf oranges for processing orange dark tea.

This study developed antimicrobial composite coatings from gelatin (GL) and carboxymethyl chitosan (CMCS) functionalized with carvacrol (CA) as a natural alternative for the preservation of strawberries. Films incorporated with 0%, 1.5%, and 3% CA were characterized by their physical, mechanical, and structural properties. The addition of CA significantly improved opacity, tensile strength, elongation-at-break, and thickness, while reducing water vapor permeability, moisture content, and solubility (p< 0.05). Spectroscopy and microscopy also confirmed CA’s uniform dispersion within the matrix. During 14 days of storage at 4 °C, strawberries coated with GL/CMCS/CA-3% significantly reduced weight loss (50.91%) and fungal contamination, improved firmness (79.31%), and maintained color and pH. Conversely, uncoated strawberries showed rapid declines in soluble solids, acidity, phenolics, anthocyanins, vitamin C, and antioxidant activity (p< 0.05). Microbial growth was effectively suppressed in coated fruits, while sensory profiles were drastically impaired in uncoated samples at the end of storage (p< 0.05). These results demonstrate that GL/CMCS/CA coatings can effectively preserve strawberry quality and extend shelf life without synthetic preservatives.

The hydrogen evolution performances of electrocatalysts are greatly restricted by their unfavorable hydrogen evolution kinetics and the undesirable accumulation of as-evolved gas bubbles on the electrocatalysts surface. Herein, we present the fabrication of self-supporting multi-heterointerfacial nanoarrays electrode toward addressing these challenges simultaneously. A monolith Ni 3 N/Ni@W 2 N 3 electrode is prepared, which exhibits a multi-heterojunction interface between the different components. The construction of this multi-heterojunction interface allows for the redistribution of the electrons, thus alleviating the strong Ni-H bond and optimizing the hydrogen adsorption free energy toward more efficient HER catalysis. Moreover, by virtue of the distinct nanoarray structure, the Ni 3 N/Ni@W 2 N 3 nanoarrays exhibit improved hydrophilicity and superaerophobicity compared with Ni/Ni 3 N, facilitating water contact and enabling more efficient detachment of the as-evolved H 2 bubbles from the surface. Benefiting from these attractive features, the Ni 3 N/Ni@W 2 N 3 nanoarrays deliver an attractive alkaline HER catalytic activity with a low overpotential of 66 mV to achieve a current density of 10 mA cm −2 , which is comparable with that of the benchmark Pt/C electrode. Moreover, the electrode exhibits remarkable stability during long-term electrolysis. The simultaneous interface and nanostructure engineering provide a feasible pathway for obtaining high-performance electrodes and beyond for various electrochemical reactions.

With the rise of green chemistry and cleaner production, the carbon-based solid acids as environment-friendly catalysts have received increasing attention worldwide. In this paper, A composite catalyst was obtained by a combination of sulfonated glucose (SG) and p -toluenesulfonic acid (PT), and identified as a catalyst for the esterification reaction between α -pinene and acetic acid (AC). It is demonstrated that the composite catalyst, possessing a high density of active sites (1.59 mmol/g of sulfonic acid and 5.05 mmol/g of total acid, respectively) and mesoporous structure (5.7 nm), demonstrates outstanding catalytic activity with a conversion of α -pinene reaching 100 % and a selectivity of 51.2 % for total ester under optimum reaction conditions. Kinetic analysis shows that the esterification reaction behaves according to pseudo-first-order kinetics, featuring an activation energy of 135.86 kJ/mol. Moreover, the thermodynamic enthalpy (Δ H ) and Gibbs free energy (Δ G ) associated with the esterification reaction are 133.05 kJ/mol and 85.86 kJ/mol, respectively, implying that this reaction is endothermic and not spontaneous. Moreover, the catalyst has been shown to be reusable up to 4 times while retaining high catalytic activity. Overall, the catalyst has demonstrated significant potential as a heterogeneous catalyst for transforming α -pinene into valuable acetates.

In this study, pure V 6 O 13 and nickel ion-doped V 6 O 13 powders were synthesized by a simple hydrothermal-calcination method, and their broad-spectrum antimicrobial properties and mechanisms were investigated. The crystal structure, morphology, and chemical state of the powders were thoroughly analyzed by XRD, SEM, TEM, XPS, and UV–Vis. Their antimicrobial properties and mechanisms were evaluated by the ring of inhibition, bio-SEM, live-dead cell staining, ROS detection, and protein leakage experiments. The results showed that nickel ion doping modulated the oxygen defects of V 6 O 13 , generating more reactive oxygen species and leading to more severe oxidative stress, resulting in a broad-spectrum and highly efficient antimicrobial effect. This study also revealed the antimicrobial mechanism based on oxygen defect -induced ROS production, which caused cellular oxidative stress damage, leading to leakage of intracellular substances and cell death. This study not only demonstrates the potential of V 6 O 13 as an efficient antimicrobial agent but also provides a strong experimental basis and theoretical support for the engineering design and optimization of novel antimicrobial materials by modulating material defects through ion doping.

The presence of hexavalent chromium(Ⅵ) Cr(Ⅵ) and antibiotics in the environment can lead to the formation of combined pollutants that are harmful to ecosystems. To address this problem, we synthesized MoS 2 embedded in the porous super-hydrophilic polyurethane (PU) sponge and used weak water flow to drive the piezoelectric catalytic synergistic degradation of Cr(Ⅵ) and tetracycline (TC). In this study, the piezoelectric properties of MoS 2 /PU were confirmed via piezoresponse force microscopy (PFM) and COMSOL multiphysics calculations. Additionally, dynamics experiments, quenching experiments, electron paramagnetic resonance (EPR) spectroscopy, three-dimensional fluorescence excitation-emission matrix (3D-EEM) spectroscopy, and free radical generation rate analysis were conducted to explore the removal performance and mechanisms of MoS 2 /PU on the TC-Cr(VI) system. The results indicated that the coexistence of the two pollutants promotes the transfer of charge in MoS 2 /PU, further combined with O 2 to produce H 2 O 2 and continued to produce OH. The removal rates of TC and Cr(VI) in the TC-Cr (VI) mixed system at 30 min were 97 % and 94 %, respectively, which were 1.45 and 1.46 times those of the single TC and single Cr(VI) systems, respectively. Finally, potentially vulnerable sites of TC were calculated and analyzed according to density functional theory (DFT). Our results provide a new strategy for improving the degradation efficiency of antibiotics and Cr(VI) metals.

The use of lubricant-infused surfaces (LIS) presents a highly promising approach to mitigating contamination from various sources, including bacteria, ice, and scale. However, these lubricants’ natural liquid characteristics frequently cause them to run out in adverse environments, which results in a failure to prevent fouling. Here, we report the sustainable anti-scaling performance of a phase-change lubricant-infused surface (PCLIS). The increased resistance is ascribed to a high degree of stability in the solid state at temperatures below PCL’s melting point ( T < T m ). Furthermore, the anti-scaling capability comes from its smooth morphology and reduced scale adhesion in liquid state ( T > T m ). As a result, this work offers a viable method to deal with scaling problems in real-world applications, especially those that involve temperature changes.

Keggin-type polyoxometalate (POM) is a new pseudocapacitive material with advanced multi-electron conduction capability, good mechanical and thermal stability. However, owing to the limited specific interfacial area and inferior conductivity of POMs, it is difficult to exert its excellent redox properties as an electrode material alone. In an effort to overcome these limitations, a heterostructured material MnPMo 8 V 6 @MXene/MoS 2 was developed using a combination of hydrothermal method and electrostatic adsorption, leveraging the synergistic self-assembly of multiple substances. The morphology and sufficient structural characterization reveal that Keggin POM and MoS 2 were homogeneously anchored on the accordion-like MXene leading to a triaryl composite. The resulting composites demonstrate improved overall performance and more efficient ion/electron transport capacity as anode materials for LIBs compared to single-component and binary materials. Typically, the compound presented a superior reversible capacity of 1061.3 mA h g −1 at 0.1 A g −1 , a high capacitance retention of 851.1 mA h g −1 after 300 cycles, and a prominent rate capacity of 450.3 mA h g −1 at 2.0 A g −1 , which surpasses the performance of most reported anodes for LIBs. Kinetic calculations also indicate that the charge accumulation functionality of MnPMo 8 V 6 @MXene/MoS 2 involves diffusion and pseudocapacitive behavior. This study combines the outstanding Faraday properties of Keggin POM, the mechanical strength of MoS 2 and the ultra-high conductivity, low impedance and high specific surface area of accordion-like MXene into the ternary composite. Meanwhile, a unique 3-D conductive network is formed among POM with regular channels, MoS 2 nanosheets and accordion-like MXene. The complementary performance and favorable morphology make the three components produce perfect synergistic effect and outstanding comprehensive lithium-ion batteries performance.

Electrolyte additive engineering is a crucial method for enhancing the performance of aqueous zinc—ion batteries (AZIBs). Recently, most research predominantly focuses on the role of functional groups in regulating electrolytes, often overlooking the impact of molecule stereoscopic configuration. Herein, two isomeric sugar alcohols, mannitol and sorbitol, are employed as electrolyte additives to investigate the impact of the stereoscopic configuration of additives on the ZnSO4electrolyte. Experimental analysis and theoretical calculations reveal that the primary factor for improving Zn anode performance is the regulation of the solvation sheath by these additives. Among the isomers, mannitol exhibits stronger binding energies with Zn2+ions and water molecules due to its more suitable stereoscopic configuration. These enhanced bindings allow mannitol to coordinate with Zn2+, contributing to solvation structure formation and reducing the active H2O molecules in the bulk electrolyte, resulting in suppressed parasitic reactions and inhibited dendritic growth. As a result, the zinc electrodes in mannitol—modified electrolyte exhibit excellent cycling stability of 1600 h at 1 mA cm−2and 900 h at 10 mA cm−2, respectively. Hence, this study provides novel insights into the importance of suitable stereoscopic molecule configurations in the design of electrolyte additives for highly reversible and high—rate Zn anodes.

In this study, the theoretical calculations proves that the combination of oxygen vacancy and amorphous carbon films in TiO 2 (V O -CT) can effectively reduce the energy bandgap and work function. The minimum Gibbs free energies required for the CO 2 RR reaction of V O -CT are 0.20 eV, which is lower than pure TiO 2 . The amorphous c@TiO 2 nanomaterials with oxygen vacancy and mesoporous structures (V O -MCT) are prepared with the P123 surfactant as the template and oxalic acid as an inducer. The electron paramagnetic resonance indicates the presence of abundant oxygen vacancy defects in the samples. UV-vis spectra indicate that the mesoporous structure enhances light absorption capacity. The photocatalytic CO 2 reduction tests show that the highest conversion rates for CH 4 and CO of V O -MCT are 14 μmol g −1 h −1 and 10.66 μmol g −1 h −1 , respectively. The electron consumption rate of V O -MCT is 12.43 times higher than that of commercial TiO 2 (P200).

With the escalating market demand for lithium, the development and efficient utilization of lithium resources have become crucial. This study introduced a method for leaching lithium from raw clay-type lithium ores using a composite sulfuric acid oxalic acid system. The experimental results revealed that the optimal conditions for the leaching process included roasting temperature of 600 °C, sulfuric acid concentration of 0.8 mol/L, liquid-solid ratio of 5 mL/g, leaching temperature of 90 °C, leaching duration of 90 min, and oxalic acid dosage of 2 g. Under these conditions, the leaching efficiency of lithium reached 93.45 %. The structural changes during the lithium leaching process and leaching mechanism were analyzed by XRD, SEM, TOF-SIMS. It was found that the minerals after mixed-acid leaching showed a loose morphology, a decrease in the average particle size, and a significant increase in the specific surface area as well as the pore volume, leading to improved lithium leaching efficiency. Furthermore, the mechanism underlying the mixed-acid leaching of lithium from clay-type lithium ores was explored. According to this mechanism, sulfuric acid first dissociated H + , which disrupted the mineral structure, allowing further destruction by oxalic acid. During this process, Li + was continuously replaced by H + and reacted with C 2 O 4 2− dissociated from oxalic acid to form water-soluble Li 2 C 2 O 4 .
