Extraction and utilization of hot carriers are considered viable approaches to surpass the Shockley–Queisser limit of perovskite solar cells (PSCs). Here, we introduce N,N′-bis(4-trifluoromethoxybenzyl) naphthalene-1,4,5,8-tetracarboxylic acid diimide (denoted as NDI-BOCF3) to modify the buried SnO2/perovskite interface, simultaneously accelerating hot-electron extraction and passivating interfacial defects. The NDI-BOCF3-modified SnO2 (denoted as SnO2–NDI-BOCF3) exhibits improved surface uniformity and optimized energy-level alignment and passivates oxygen vacancies (VO), thereby providing ∼22% enhancement in hot-electron extraction. Nonadiabatic molecular dynamics simulations confirmed that NDI-BOCF3 enhances hot-electron extraction via higher-frequency lattice vibrations and more ordered nonadiabatic couplings at the interface. In addition, NDI-BOCF3 passivates multisite defects across various perovskite terminations. As a result, SnO2–NDI-BOCF3 devices achieve a power conversion efficiency (PCE) of 25.06%, compared to 23.96% for a device with pristine SnO2. An increase of PCE from 8.81 to 17.50% for SnO2-free devices is also achieved. Furthermore, due to passivation, the activation barrier for positively charged iodine vacancies (VI+) increases from 0.80 to 0.87 eV, resulting in an enhancement in the thermal and photostability of the perovskite thin films.

Deltamethrin (DEL) is a highly potent and persistent pyrethroid insecticide, and its widespread accumulation poses significant ecological risks. While microbial biodegradation targeting ester bond cleavage offers a promising green remediation strategy, free bacterial cells often exhibit poor operational stability and are vulnerable to environmental stresses under realistic conditions. To address this challenge and develop robust biocatalysts, we initially screened for a strain possessing high esterolytic potential using a rapid p -nitrophenyl acetate (p-NPA) hydrolysis assay, identifying Stenotrophomonas sp. Klm2. To enhance its physiological resilience for practical application, whole Klm2 cells were encapsulated within a sodium alginate/chitosan (SA/CTS) dual-network hydrogel composite. Characterization revealed that structural synergy between the biopolymers improved network integrity, providing a protective microenvironment that significantly bolstered the biocatalyst's tolerance to thermal fluctuations, pH shifts, and chemical toxicity compared to free counterparts. The encapsulated Klm2@SA/CTS exhibited remarkable stability, retaining 90.2% of its initial catalytic activity after 7 days of storage at 25 °C and maintaining performance over 8 reuse cycles, with only a 25.9% total activity loss. Crucially, under high DEL loading conditions (200 mg/L), the encapsulated cells outperformed free cells by a wide margin. This enhanced performance was driven by a demonstrated synergistic mechanism coupling rapid physical adsorption onto the hydrogel matrix with sustained intracellular biochemical degradation. This study highlights how rationally engineering the biopolymer microenvironment modulates mass transfer and microbial stability, establishing a reusable, physiologically robust whole-cell platform for efficient pesticide detoxification.

Introduction N -acetylglucosamine (GlcNAc) serves as a signaling molecule that triggers a variety of physiological responses in microorganisms. However, its regulatory roles in metabolite biosynthesis and siderophore production in Lysobacter sp. 3655 remain unclear, especially regarding the quorum sensing (QS) signal 4-hydroxybenzoic acid (4-HBA) and the siderophore lysochelin under iron-deficient conditions. This study aimed to explore the regulatory effects of GlcNAc on metabolite profiles and lysochelin biosynthesis in Lysobacter sp. 3655. Methods Lysobacter sp. 3655 was cultured in oligotrophic medium with GlcNAc induction. The induced differential metabolite was isolated and structurally identified by nuclear magnetic resonance and liquid chromatography-mass spectrometry. Gene deletion mutants of GlcNAc catabolic genes ( nagA , nagE2 ), and L-phenylalanine biosynthesis gene (pheA) were constructed, as well as multiple deletion mutants in the lenB2 (4-HBA biosynthetic gene) mutant background. Growth status and lysochelin yield of these mutants were evaluated under iron-deficient conditions. Exogenous complementation assays were performed using 4-HBA, GlcNAc, p -hydroxybenzaldehyde, cinnamic acid, and p-hydroxycinnamic acid to verify their functional effects. Results GlcNAc specifically induced the production of a unique metabolite in Lysobacter sp. 3655, which was identified as p -hydroxybenzaldehyde. Deletion of nagA , nagE2 , or pheA completely abolished GlcNAc-induced p -hydroxybenzaldehyde biosynthesis. The lenB2 mutant showed significant growth defects and remarkably decreased lysochelin production under iron limitation, while exogenous 4-HBA or GlcNAc restored both phenotypes. Further disruption of nagA , nagE2 , or pheA in the lenB2 mutant eliminated the complementation effect of GlcNAc on lysochelin production. p -hydroxybenzaldehyde restored lysochelin biosynthesis by converting to 4-HBA, and the L-phenylalanine catabolic intermediates cinnamic acid and p-hydroxycinnamic acid also rescued the growth and lysochelin production defects of the lenB2 mutant. Discussion Our results reveal that GlcNAc regulates two metabolic pathways in Lysobacter sp. 3655: it promotes p -hydroxybenzaldehyde production through GlcNAc catabolism and L-phenylalanine metabolism, and restores lysochelin biosynthesis in the QS-deficient lenB2 mutant via either 4-HBA converted from p -hydroxybenzaldehyde or alternative pathways mediated by L-phenylalanine catabolites. These findings uncover a novel regulatory network controlling lysochelin biosynthesis in Lysobacter sp. 3655, providing important references for investigating the biocontrol mechanisms of Lysobacter species.

PtCo nanoparticles anchored on P,S,N-doped porous carbon nitride enables strong ORR activity. • Hierarchical porosity and heteroatom doping enhance Pt dispersion and mass transport. • PtCo/P,S-HPCN shows 2.37 mA cm ⁻2 Pt ⁻1 activity and superior ORR durability. • Outperforms commercial Pt/C in both RDE and single-cell PEMFC performance tests. • Robust carbon nitride support resists corrosion in acidic, high-potential environments. Maximize the Pt utilization with high durability and efficient mass transport is crucial on the electrocatalyst design for the practical low-temperature fuel cell applications. In this work, we designed an ultrafine PtCo alloy nanoparticles distributed uniformly on phosphorus and sulfur co-doped hierarchical porous carbon nitride (PtCo/P,S-HPCN), synthesized via hydrothermal treatment, pyrolysis, and chemical reduction. The heteroatom-doped carbon nitride framework exhibits superior chemical stability compared to conventional carbon materials, while its hierarchical porous structure facilitates uniform dispersion of ultrafine PtCo nanoparticles (∼1.8 nm) and accelerates reactant transport. Synergistic effects from graphitic/pyridinic nitrogen species, P/S doping, and Pt–Co alloying modulate the electronic structure of Pt, optimizing *OOH binding and enhancing ORR kinetics. The optimized catalyst delivers excellent performance in acidic media, achieving a high half-wave potential (0.88 V vs. RHE), a mass activity of 0.91 mA µgPt⁻ 1 , and a specific activity of 2.37 mA cmPt⁻ 2 at 0.85 V. Remarkably, it retains 73% of its initial mass activity and loses only 11 mV in half-wave potential after 5000 durability cycles. In practical PEMFC tests, the PtCo/P,S-HPCN cathode achieves a peak power density of 0.42 W cm⁻², surpassing commercial 40 wt% Pt/C. This study demonstrates a promising strategy for designing durable, low-Pt and high activity catalysts for PEMFC applications.

Phenol and p -nitrophenol (PNP) are often co-detected in high-saline phenolic wastewater and combined toxicity caused by phenolic compounds poses potential risks to higher organisms, which have aroused serious concern for phenolic wastewater treatment. In this study, a halophilic bacterium Halomonas cupida J9 was engineered by genomic integration of phenol and PNP biodegradation pathways and the gfp gene (coding for green fluorescent protein), resulting in a fluorescently-labeled and halotolerant degrader (named J9U-PP). The transcription of all nine exogenous genes was achieved in strain J9U-PP. Strain J9U-PP was able to degrade 25 mg/L phenol in high-salt media containing 6% NaCl, and it also had the ability to degrade 25 to 100 mg/L PNP in high-salt media containing 6 to 10% NaCl. Moreover, strain J9U-PP was capable of mineralizing phenol and PNP to CO 2 in high-salt media. More importantly, co-mineralization of phenol and PNP by strain J9U-PP was verified in laboratory-amended wastewater samples. We demonstrate for the first time co-mineralization of phenol and PNP by an engineered halotolerant chassis. Strain J9U-PP can be easily tracked by green fluorescence in natural environments. Strain J9U-PP displayed superior growth kinetics and excellent genetic stability during passage culture. These merits make strain J9U-PP an ideal candidate for the remediation of hypersaline environments co-contaminated with phenol and PNP. This study suggests that constructing composite degradation circuits in an extremophile chassis may serve as a promising strategy for the remediation of extreme environments co-contaminated with multiple pollutants.

As emerging contaminants of concern, p -phenylenediamines (PPDs) and their quinone transformation products (PPD-Qs) serve as critical indicators of pollutant inputs from urban runoff and tire wear to coastal ecosystems. However, their occurrence, distribution, and pollution sources in Zhejiang's estuarine-coastal sediments remain uncharacterized. This study investigated the pollution levels and ecological risks of PPDs and PPD-Qs in estuarine and coastal sediments in Zhejiang Province. The results revealed the widespread occurrence of eight PPDs and seven PPD-Qs. The concentrations of Σ 8 PPDs in estuarine and coastal sediments were 3.13–9.03 ng/g dry weight (dw) and 2.30–23 ng/g dw, with N -Isopropyl- N′ -phenyl- p -phenylenediamine (IPPD) being the predominant congener. Concentrations of Σ 7 PPD-Qs ranged from 1.64 to 4.35 ng/g dw in estuarine sediments and from 0.80 to 6.87 ng/g dw in coastal sediments, and were dominated by N , N′ -Bis(methylphenyl)-1,4-benzenediamine quinone (DTPD-Q) and 6PPD-Q. Notably, a significant ( P < 0.05) positive correlation was observed between the concentrations of PPDs and PPD-Qs in estuarine sediments. Priority assessment identified that N, N′ -Bis(2-naphthyl)- p -phenylenediamine (DNPD), N, N′ -Bis(methylphenyl)-1,4-benzenediamine (DTPD), DTPD-Q, and 6PPD-Q were of highest priority. Moreover, 6PPD-Q was identified as a medium or high ecological risk at all sites. This study provides critical baseline data and risk insights for emerging rubber-derived contaminants (PPDs/PPD-Qs), enabling targeted conservation strategies for ecologically vulnerable estuarine-coastal systems.

The design of low-smoke and low-toxicity epoxy resin (EP) composite materials remained a significant challenge. In this study, a multifunctional MOF-based flame retardant (TP-P-Co-MOF) was synthesized using ZIF-67 as the framework via a three-step modification process. TP-P-Co-MOF incorporated Schiff base-conjugated structures, Co P synergistic flame-retardant sites, and a porous architecture, while exhibiting excellent compatibility with EP. At a 4 wt% loading, the EP/TP-P-Co-MOF composite attained a UL-94 V-0 classification and an LOI of 31.3%. Additionally, in comparison with EP, the EP/TP-P-Co-MOF composite exhibited marked reductions in the peak heat release rate (PHRR), total heat release (THR), peak smoke production rate (PSPR), and total smoke production (TSP), which decreased by 43.1%, 14.9%, 64.0%, and 52.6%, respectively, thereby demonstrating outstanding flame-retardant efficiency and toxic-smoke suppression performance. Investigation of the flame-retardant mechanism indicated that TP-P-Co-MOF not only significantly improved the quality of the graphitized carbon layer in EP, but also reduces the concentration of combustible gases, thereby exerting synergistic flame-retardant effects in both the condensed and gas phases. With respect to mechanical properties, the incorporation of TP-P-Co-MOF improved both the toughness and strength of the EP. The tensile strength and impact strength increased by 11.1% and 24.7%, respectively, in comparison with neat EP. This study provided a promising strategy for developing highly efficient MOF flame retardants while offering a novel approach to designing low-smoke, low-toxicity flame-retardant EP.

Constructing vanadium oxide/metal selenide heterostructure is a promising strategy to enhance the reaction kinetics and structural stability for high-performance sodium-ion batteries (SIBs) anode. However, achieving a uniform and robust heterointerface remains challenging due to the multivalent state transformation of the V and the thermodynamic stability difference between V O and V Se bonds. Herein, we design and synthesize the V 2 O 3 /Fe 3 Se 4 @C heterostructure via a facile liquid-phase reaction followed by a seleniziation method. The unique coordination environment in a ferric vanadate and the reduction potentials difference between Fe and V cations promote the formation of a well-defined heterointerface. Density functional theory calculations confirm the formation of a built-in electric field at the heterointerface, thereby accelerating the reaction kinetics. The electric field originates from the orbital hybridization, which promotes the formation of a robust Se V O bonding configuration. Meanwhile, the carbon coating maintains structural integrity by suppressing volume expansion during cycling. These synergistic effects effectively enhance the overall structural stability of the material. Thus, the prepared V 2 O 3 /Fe 3 Se 4 @C anode exhibits exceptional electrochemical performance, delivering a high specific capacity of 378.2 mAh g −1 at 0.5 A g −1 and 308.9 mAh g −1 at 8 A g −1 , and retaining a specific capacity of 313.8 mAh g −1 after 2500 cycles at 5 A g −1 . This work establishes a new electron orbital modulation strategy for exploring high-performance vanadium oxide-based anode materials for SIBs.

With excellent thermal and chemical stability, tin dioxide (SnO2) has emerged as a promising electron transport layers (ETLs) for the high-efficiency n–i–p perovskite solar cells (PSCs). However, for perovskite films deposited on SnO2, the surface hydroxyl groups of SnO2 and lattice mismatch lead to severe nonradiative charge recombination at the buried interface. Moreover, the inherent brittleness of perovskite renders the buried interface mechanically more vulnerable. In this work, a dipolar π-conjugated molecule, 3,5-diaminobenzotrifluoride (CF3-mDA), is employed as a buffer layer to modify the buried interface of PSCs with a relatively wide bandgap (1.60 eV). This buffer layer effectively coarsens the perovskite grains at the buried interface, increasing the grain size from 381.50 nm to 503.47 nm, and further enhances the mechanical toughness of the buried interface and mitigates the risk of interfacial fracture. Furthermore, it passivates the defects of both SnO2 and perovskite through its functional groups, as well as induces a more favorable energy band alignment. With this buried interface modification, the champion device delivers an average power conversion efficiency (PCE) increased from 18.74% to 21.93% (22.12% under reverse scan, RS, and 21.74% under forward scan, FS), with an average open-circuit voltage (VOC) boosted from 1.188 V to 1.232 V and a significantly suppressed hysteresis. The modified devices also show a higher environmental stability than the control counterparts, maintaining an average 85.20% of their initial PCE after 16 days of storage in ambient air (with 25% relative humidity, RH, and at room temperature, RT).

Developing an effective electrocatalyst to regulate the kinetics of the sulfur redox reaction is essential for inhibiting polysulfide shuttling in Li-S batteries. Here, the electronic structure of CoTe, modulated by cation doping, is systematically investigated to elucidate how orbital hybridization optimizes sulfur redox electrocatalysis. Among the cation-doped CoTe compounds, the introduction of Ni dopants results in the most significant shift of the p-band center of CoTe (Ni-CoTe) towards the Fermi energy level, which facilitates the formation of numerous Te vacancies on the CoTe surface. This structural configuration endows CoTe with a multitude of active sites that bind polysulfide intermediates, lowering the activation energy (Ea) of the sulfur reduction reaction, specifically reducing the Ea for the conversion of lithium polysulfides to Li2S from 0.73 eV to 0.65 eV. As a result, the Li-S battery with Ni-CoTe catalyst delivers exceptional cyclability, with a low-capacity decay of 0.049% per cycle over 1,000 cycles at 2.0 C. Moreover, an initial areal capacity of 13.5 mAh cm-2 at 0.02 C is achieved with a high sulfur loading (10.0 mg cm-2) and a low electrolyte-to-sulfur ratio (5.0 µL mg-1). These findings will provide fundamental insights into orbital-level catalyst design principles for advanced sulfur electrochemistry.

The catalytic conversion of lignin derivatives into specific chemicals represents a key pathway for achieving high-valued utilization of biomass. A new Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst was constructed for the selective demethoxylation of vanillic acid derived from lignin depolymerization to produce p-Hydroxybenzoic acid. Compared to Ag–Co 0 /CoO, Fe doping suppressed Co reduction, endowing the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst with suitable hydrogenation activity and more abundant acidic sites. The hydrogen spillover effect inhibited decarboxylation, dehydroxylation, and benzene ring hydrogenation during the demethoxylation reaction. Oxyphilic Fe species changed the adsorption geometry of vanillic acid from parallel adsorption into twist configuration, avoiding the hydrogenation of benzene ring, and thereby improving the demethoxylation selectivity to p-Hydroxybenzoic acid. By optimizing catalyst preparation and reaction conditions to minimize decarboxylation and over-hydrogenation byproducts, the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst contributed to a 98.52% conversion of vanillic acid and a 89.62% selectivity to p-Hydroxybenzoic acid under 0.4 MPa H 2 , 0.4 MPa CO 2 at 220 °C for 2 h. This research provided a theoretical foundation and practical guidance for the catalytic demethoxylation of phenolic acids, offering new insights into high-valued utilization pathways for biomass.

Sodium metal batteries (SMBs) are regarded as compelling energy storage systems owing to their high theoretical capacity and the abundance of sodium (Na). However, SMBs with cycling stability under extreme climatic conditions remain highly challenging, due to the instability of the solid electrolyte interphase (SEI) and dendrite growth, which is further aggravated when operating under low negative-to-positive capacity ratio (N/P) conditions. Herein, a high-energy-density and wide-temperature SMB is realized using a hetero-salt-regulated electrolyte strategy. Specifically, lithium difluorophosphate (LiDFP) is introduced as a hetero-salt additive into a dual-salt ether electrolyte to stabilize the Na metal anodes. Li + competitively coordinates with solvent molecules, causing the Na + solvation structure to shift toward an anion-rich configuration. The formed anion-dominated solvation shell promotes the formation of a mechanically robust and electronically insulating LiF/NaF-rich SEI, which in turn suppresses interfacial side reactions and effectively mitigates dendrite growth. Consequently, the assembled Na||Na 3 V 2 (PO 4 ) 2 F 3 (NVPF) SMBs (N/ P = 4:1) achieve a high energy density of 335.90 Wh kg −1 (with power density of 26,650.00 W kg −1 ) at 25 °C (based on total mass of the active materials on anode and cathode) and maintain stable operation across a wide temperature range of −40 to 45 °C. This work expedites the development of SMBs for energy-intensive applications in extreme environments. Download: Download high-res image (228KB) Download: Download full-size image
