Electric field-assisted composting (EC) is a novel technology for enhancing compost humification. Elucidating the role of electric field application in promoting humification and identifying enhancement strategies remains a key challenge. This study investigated the role of conductive and redox pathways in enhancing the humification efficiency of EC systems through the incorporation of conductive graphite and sodium lignosulfonate. Compared with EC, the conductive graphite treatment (EGPC) and sodium lignosulfonate treatment (ESLC) increased current intensity by 2.5- and 1.8-fold, respectively. Additionally, humic acid (HA) content increased by 62.34 % in EGPC and 60.86 % in ESLC. EGPC treatment increased the abundance of Bacillus and enhanced synergistic interactions among core bacteria. Conversely, ESLC treatment significantly altered β-diversity and increased the abundance of Flavobacterium during composting. Correlation analysis and partial least squares path modeling indicated that EGPC treatment promoted direct electron transfer and bacterial interactions, thereby enhancing organic matter humification. ESLC treatment improved bacterial community diversity and facilitated the conversion of furanic acid into HA. These findings provide a theoretical basis for optimizing EC and highlight its potential for large-scale application.

This study investigated the effects of gamma irradiation (GI) at a dose of 0.6 kGy on the dynamic changes of volatile and non-volatile compounds in Cara Cara oranges during postharvest storage. Sixty-one volatile components were identified, with total relative concentrations ranging from 2465.89 to 5785.54 μg/L. Limonene, linalool, ethyl butyrate, ethyl 2-methylbutyrate and nerolidol were identified as key aroma-active compounds in fresh Cara Cara oranges. The application of GI treatment reduced limonene content and enhanced esterification, promoting ethyl butyrate and ethyl 2-methylbutyrate as dominant aroma contributors in stored fruit. The GI treatment significantly reduced the fruit damage rate and MDA content while enhancing antioxidant capacity in Cara Cara fruit during prolonged storage. Through a widely targeted analysis, 134 differential non-volatile metabolites were annotated in the KEGG pathway. Elevated levels of key metabolites and the increased activity of rate-limiting enzymes (PFK, PAL, 4CL, ACC, SDH, and MDH), suggested GI might potentially accelerate metabolic flux in postharvest Cara Cara oranges. Overall, this study indicated that GI treatment could effectively reduce postharvest damage in Cara Cara oranges while modulating flavor profiles and metabolic responses.

Icing or frosting on transparent surfaces pose significant challenges for the reliability of optical devices. Although various transparent photothermal coatings have been proposed to alleviate ice accumulation via solar-induced surface heating, their limited fabrication strategy and mechanical stability greatly constrain practical implementation. In this study, we present a facile and effective in situ polymerization method to fabricate a transparent, photothermal, and mechanically durable anti-icing coating. The coating is fabricated through in situ polymerization of polydopamine (PDA) onto transparent substrate, which is then followed by the surface grafting of polydimethylsiloxane (PDMS) brushes. In this coating system, PDA not only serves as a proficient solar-thermal converter and but also supplies an abundance of catechol groups for subsequent PDMS grafting. By tuning the PDA deposition time, the light transmittance and photothermal performance of the coating was precisely controlled. Under 1 sun irradiation, the PDA 24 @PDMS coating increases the surface temperature of 26.2 °C in −20 °C surroundings, while retaining a high transmittance of 64.8 % at 550 nm. Furthermore, after grafting PDMS brushes, the coating presents excellent oleophobic, self-cleaning and icephobic properties. More importantly, the incorporation of PDMS brushes reduces the PDA@PDMS surface friction coefficient (∼ 0.1) and improves the surface abrasive resistance that can endure over 9000 abrasion cycles. This study highlights a facile fabrication approach for the practical application of multifunctional transparent photothermal anti-icing coating in harsh environments.

Lithium-ion batteries (LIBs) attract widespread attention as promising energy storage devices owing to their superior energy density, excellent cycle life, and absence of memory effect. However, they still encounter challenges in high-rate performance and structural stability, necessitating further optimization. This study focuses on a composite anode material constructed from black phosphorus (BP), tungsten disulfide (WS 2 ), and ultra-high-purity whisker carbon nanotubes (UWCNTs) (BP-WS 2 -UWCNTs). The research investigates the regulatory effects of phosphorus–carbon (P–C) and phosphorus–sulfur (P–S) bonds at the material interface on electrochemical performance. Characterization indicates the establishment of P–C and P–S bonds at the composite interface, which enhance structural integrity and improve electron/ion transport capabilities. Electrochemical performance evaluations validate the combined effect of these interfacial bonds: at 2.0 A g −1 , the BP-WS 2 -UWCNTs anode delivers 605.8 mAh g −1 for 2000 cycles, and retains 252.2 mAh g −1 after 3000 cycles even at 15.0 A g −1 , exhibiting remarkable rate performance and prolonged cycling durability. In practical applications of LIBs, the composite anode maintains robust structural integrity and outstanding electrochemical performance. This work highlights that the combined effect of interfacial P–C and P–S chemical linkages effectively facilitates lithium-ion diffusion and stabilizes the electrode structure, offering valuable insights and viable strategies for advancing high-capacity anode design in LIBs.

Perovskite solar cells (PSCs) suffer from a high density of defects at the buried bottom interface, which negatively impacts the efficiency in the PSCs and interface recombination. This is primarily due to carrier recombination losses occurring at the perovskite/SnO 2 . In this study, a two-dimensional lamellar V 2 CT x MXene materials, synthesized by hydrofluoric acid (HF) etching, was incorporated at the buried interface between the SnO 2 electron transport layer and the perovskite layer. The introduction of a V 2 CT x MXene modified layer at the perovskite/SnO 2 buried interface simultaneously modulates the crystallization and defect passivation within the perovskite material, leading to enhanced grain size and crystallinity. Consequently, highly efficient and stable PSCs were achieved. The presence of terminal group T x (OH − , F − ) in V 2 CT x facilitates the transfer of electrons to the 6p vacant orbitals of Pb 2+ ions, promoting the formation of Pb-F complexes. These complexes effectively suppress uncoordinated Pb ions at the perovskite interfaces, thereby significantly reducing defect density. As a result, the V 2 CT x -modified PSCs achieve an average power conversion efficiency (PCE) of 14.6 %, a notable improvement over the 12.8 % of the control devices, while also enhancing operational stability. This research provides a convenient and effective approach for enhancing crystallization and passivation defects in perovskite films, thereby improving device efficiency and stability.

Modifying nanoparticle assembly can alter the electric field strength within “hot spots,” offering promise for enhancing surface-enhanced Raman scattering (SERS) performance. In this work, by modifying the surface of Ag nanoparticles (AgNPs) with glutathione (GSH), a pH-responsive substrate, Ag-GSH nanoparticles (AGGNPs), was prepared. Under acidic conditions, hydrogen bonds form between protonated GSH molecules, inducing aggregation of AGGNPs and causing a red shift in the absorption peak. The SERS enhancement factor (EF) increased from 5.6 × 10 5 to 1.36 × 10⁶ and exhibited a good linear relationship with pH. In practical apple sample detection, the natural acidic environment of the fruit pulp enabled SERS self-optimization. Without external acid addition, the signal for thiram at 1383 cm −1 was significantly enhanced, achieving a minimum detection concentration of 10 −11 M. This approach effectively provides a novel pathway for developing highly efficient SERS sensing strategies and offers fresh insights for expanding SERS applications in agricultural detection.

Green mold, caused by Penicillium digitatum , is one of the most destructive postharvest diseases of citrus fruits, leading to significant rot and economic losses. In this study, the antifungal activity and underlying mechanism of the novel antimicrobial peptide (AMP) N1–6L7A against P. digitatum were investigated. Additionally, the potential application of N1–6L7A for controlling postharvest green mold in Citrus sinensis (L.) Osbeck was examined. N1–6L7A exhibited potential antifungal efficacy by inhibiting both mycelial growth and spore germination of P. digitatum . Furthermore, it demonstrated excellent thermal stability, pH tolerance, and biosafety. The results of fluorescence microscopy assay, cell component leakage, and microscopic observations revealed that N1–6L7A severely damaged the fungal membrane of P. digitatum , leading to the release of intracellular nucleic acids and proteins. N1–6L7A treatment also induced excessive intracellular reactive oxygen species (ROS) production, collapse of mitochondrial membrane potential, and decreased activities of malate dehydrogenase (MDH) and ATPase. Gel retardation assay indicated that P. digitatum -DNA was a target of N1–6L7A. Furthermore, transcriptomic analysis suggested that N1–6L7A might inhibit the growth of P. digitatum by blocking the expression of genes related to the ribosome, amino acid metabolism, and pyrimidine metabolism. Meanwhile, the peptide potentially promoted the expression of genes involved in steroid biosynthesis. Notably, in vivo assays confirmed that N1–6L7A effectively controlled P. digitatum infection in citrus fruits and enhanced host resistance by activating defense-related enzymes. Collectively, our results suggested that N1–6L7A could be used as an alternative fungicide to prevent green mold in citrus fruits.

Halide methyltransferases (HMTs) can efficiently catalyze the biosynthesis of S -adenosyl methionine (SAM) using natural substrates like methyl iodide or environmentally friendly alternatives such as methyl p-toluene sulfonate (MeOTs). Leveraging their broad substrate promiscuity, HMTs can also accommodate long-chain alkyl iodides and sulfonate esters, thereby facilitating the enzymatic production of structurally diverse SAM analogues. To address the limitations of existing S -adenosyl-ethionine (SAE) synthesis routes that depend on toxic alkyl halides like ethyl iodide, we developed a sustainable enzymatic strategy using ethyl p-toluene sulfonate (EtOTs) as the ethyl donor. Through a proximal-to-distal molecular engineering strategy, we systematically engineered wild-type Aspergillus clavatus halide methyltransferase ( Ac HMT) to enhance its catalytic properties. Following multiple rounds of semi-rational design, the mutant Ac HMT M4 exhibited a 6.0-fold increase in specific activity toward EtOTs compare to the wild-type, reaching 0.30 mU mg −1 , which represents the highest catalytic efficiency reported to date for this substrate. Molecular dynamics simulations subsequently revealed the structural mechanism of the improved catalytic activity. Biosynthesis of ethyl vanillin was achieved through a designed dual-enzyme cascade reaction. This work provides a universal strategy for engineering HMT to utilize sulfonate ester substrates, and an efficient biocatalyst for green synthesis of SAE for further ethyl modification of functional molecules.

In this study, novel Z-scheme AgI@PbBiO 2 Br heterojunctions were prepared using a simple in situ precipitation approach to effectively degrade organic pollutants and inactivate gram-negative Escherichia coli (E. coli) and gram-positive Staphylococcus aureus (S. aureus) bacteria when exposed to visible light. The prepared materials were comprehensively evaluated using several analytical procedures. The 20 %-AgI@PbBiO 2 Br presented the best photocatalytic performance of all the catalysts prepared. The rhodamine B (RhB) molecules were significantly reduced within 70 min (98.72 %), showing a much higher degradation efficiency than bare AgI (73.58 %) and PbBiO 2 Br (46.77 %) under the same conditions. The degradation of methyl orange (MO), neutral red (NR), and tetracycline (TC) by 20 %-AgI@PbBiO 2 Br was also examined, resulting in nearly total elimination of MO, NR, and TC pollutants, respectively. In addition, the antibacterial efficacy of 20 %-AgI@PbBiO 2 Br against E. coli and S. aureus reaches about 99.99 %. The improved photodegradation efficacy of AgI@PbBiO 2 Br is owing to the construction of a heterojunction between AgI and PbBiO 2 Br, which increases effective charge separation and visible light absorption, thus enabling the decomposition of pollutants. Cycling experiments confirmed the stability and reusability of the material, demonstrating exceptional photocatalytic durability. The photocatalytic mechanism was thoroughly examined by reactive species capture assays and ESR analysis, confirming that holes and superoxide radicals are crucial in the photodegradation system. Additionally, the density functional theory (DFT) simulations and liquid chromatography-mass spectrometry (LC-MS) helped to clarify the susceptible active sites and possible degradation pathways of RhB. Overall, this work underlines the considerable ability of AgI@PbBiO 2 Br heterojunctions to effectively remove persistent pollutants from wastewater.

Graphitic carbon nitride (g-C 3 N 4 ) is widely recognized as the most promising photocatalysts for photocatalytic hydrogen evolution. However, the high charge recombination, low crystallinity, and low number of reactive sites limit its photocatalytic H 2 performance. To address above issues, we report that the modification of g-C 3 N 4 was realized through crystallinity-improving and element-doping, enhancing the photocatalytic performance of g-C 3 N 4 . Specifically, the ordered/disordered polymer crystalline carbon nitride was prepared by the molten salt method, which fragmentizes g-C 3 N 4 into order/disorder crystalline carbon nitride(CN-NH 4 -NaK). Then, crystalline carbon nitride was modified with Ru nanoclusters (Ru/CN-NH 4 -NaK). As a result, 0.38 %Ru/CN-NH 4 -NaK features extending visible light absorption and suppressing charge recombination, showing an excellent photocatalytic turnover frequency (14962.240 μmol . g −1 . h −1 ). This TOF value is approximately 7 times compared to the g-C 3 N 4 loaded with Ru (2147.075 μmol . g −1 . h −1 ). The phenomenon could be attributed to the metal-supported interaction between Ru nanoclusters and modified g-C 3 N 4 , which can control the local charge distribution, facilitating the effective charge transfer and enhancing the catalytic activity. This strategy provides a green and clean method to the preparation of ordered/disordered polymer crystalline carbon nitride with metal doping, aiming to improve charge separation efficiency and enhance photocatalytic performance.

Tin selenide (SnSe), as a direct bandgap (1.1–1.3 eV) photovoltaic absorber material, has a theoretical power conversion efficiency comparable to commercial thin-film solar technologies. However, the efficiency of experimentally fabricated SnSe solar cells is significantly lower than the theoretical value, mainly constrained by two major bottlenecks: (1) the bulk defects leading to carrier recombination and (2) the bandgap mismatch at the interface. Additionally, the environmental toxicity of the CdS and its parasitic absorption of short-wavelength light also limit the sustainable development. This study proposes and systematically investigates the all-inorganic structure of FTO/Zn(O,S)/SnSe/Carbon. Replacing traditional CdS with Zn(O,S) can achieve tunable bandgaps and eliminate Cd toxicity. Through SCAPS-1D simulation, the thickness and carrier concentration of each functional layer are optimized, and the influences of bulk defect density, interface defect density, and resistance on device performance are analyzed. Meanwhile, the S content in Zn(O,S) is adjusted, and the sulfur enrichment (S content of 70%) induces the best conduction band offset (ΔEc = 0.05 eV). The resulting optimal device exhibits an efficiency of 22.46%, Voc = 0.90 V, Jsc = 30.06 mA/cm2, and FF = 83.39%. This work establishes a universal paradigm combining nontoxic material selection (Zn(O,S)/carbon), interface thermodynamic control, and defect passivation strategies, paving the way for the commercialization of sustainable thin-film solar cells.

The shrinkage rate of Ni0.6Zn0.4Fe1.8O4 (NZF) ferrite was controlled to enable cofiring with BaTiO3 (BTO) at 1250 °C, forming BTO-NZF laminated structures. Postcofiring microstructural analysis revealed a well-bonded interface with minimal elemental interdiffusion. Notably, Ti4+ exhibited the highest diffusion coefficient (1.60 ± 0.05 × 10–12 cm2/s). Unidentified phases on the NZF side effectively restricted Ba2+ and Ti4+ diffusion. The BTO-NZF heterojunction consisted primarily of nanoscale amorphous layers containing Ba2+ and coherent crystalline regions. The dense amorphous barrier layer not only ensured strong interfacial bonding but also significantly suppressed interdiffusion. High-quality heterojunction formation was influenced by four primary factors, including the presence of similar ionic radii and interplanar spacings, amorphous barrier layers, and a certain concentration of large-radius ions. Magnetic characterization showed that NZF had a saturation magnetization (Ms) of 70.29 ± 0.50 emu/g, a coercivity (Hc) of 8.89 ± 0.50 Oe, and a remanent magnetization (Mr) of 1.01 emu/g. The relative dielectric constant (εr) of BTO ranged from 1490 to 2500 (at 1 MHz), while the dielectric loss tangent (tanδ) varied between 4 × 10–3 and 1.25 × 10–2. These findings offer valuable guidance for selecting cofired laminated substrates and designing high-performance heterojunctions. Moreover, the resulting cofired laminates exhibit excellent electromagnetic properties, demonstrating strong potential for magnetoelectric coupling applications.
