Deoxynivalenol (DON) is one of the mostly concerned mycotoxins and several microbes showed bioremediation effects on DON toxic effects. In this study, the acute toxicity of a new DON degrading strain Achromobacter spanius P-9 with DON on zebrafish embryos and adults were firstly performed. For zebrafish embryos, bacterial concentrations of 2.5 × 10 7 CFU/mL and 5.0 × 10 7 CFU/mL had no significant effects on growth and development. However, at 7.5 × 10 7 CFU/mL, some effects were observed, and at 10.0 × 10 7 CFU/mL, the embryo survival rate decreased to 70%, with 3.3% teratogenicity. Higher bacterial concentrations correlated with faster heart rates. DON (100 μg/mL) significantly reduced embryo survival to 36.7% in 96 h. Bacterial solutions at 7.5 × 10 7 CFU/mL and 10.0 × 10 7 CFU/mL expanded the zebrafish intestinal tissue wall, while DON at 100 μg/mL negatively impacted intestinal morphology. Liver tissue in zebrafish exposed to Achromobacter spanius P-9 showed no significant differences from the control group. However, exposure to DON solution increased liver fluorescence intensity and caused liver cell changes, including edema, vacuolization, and blurred boundaries. For adult zebrafish, the ROS and 8-OHdG contents in the exposure group increased with the increase of bacterial solution concentration, the SOD enzyme activity, CAT enzyme activity, GST enzyme activity and MDA was not significantly different with the control group. Compared with the control group, the content of ROS, GST enzyme activity, MDA and 8-OHdG after DON treatment showed an upward trend, SOD and CAT enzyme activities showed a decreasing trend. Achromobacter spanius P-9 has no obvious inhibitory effect on the growth and development of zebrafish embryos and has no obvious death and toxicity during the growth of adult fish, providing data support for the future application of this strain in the biodegradation of DON.

In this work, a highly efficient and environmentally friendly chitosan-based graft flocculant, namely, acrylamide- and dimethyl diallyl ammonium chloride-grafted chitosan [CS-g-P(AM-DMDAAC)], was prepared successfully through plasma initiation. FTIR results confirmed the successful polymerization of CS-g-P(AM-DMDAAC) and P(AM-DMDAAC). P(AM-DMDAAC) was the copolymer of acrylamide- and dimethyl diallyl ammonium chloride. SEM results revealed that a densely cross-linked network structure formed on the surface. XRD results verified that the ordered crystal structure of chitosan in CS-g-P(AM-DMDAAC) was changed into an amorphous structure after plasma-induced polymerization. The flocculation results of low-algal-turbidity water further showed the optimal flocculation efficiency of turbidity removal rate, COD removal rate, and Chl-a removal rate were 99.02%, 96.11%, and 92.20%, respectively. The flocculation efficiency of CS-g-P(AM-DMDAAC) were significantly higher than those obtained by cationic polyacrylamide (CPAM) and Polymeric aluminum and iron (PAFC). This work provided a valuable basis for the design of eco-friendly naturally modified polymeric flocculants to enhance the flocculation of low-algal-turbidity water.

Transition metal selenides have the leading position in the field of energy storage and conversion due to their high theoretical capacity, good electrical conductivity, and cycling stability. Nickel is widely used for the construction of positive electrodes in devices due to its good conductivity, variable valence state, and ideal redox activity. NiSe materials have high internal resistance and are prone to volume change during charging and discharging, thus affecting the practical application of this electrode material, and the reported NiSe materials have not achieved a more desirable capacity value. Therefore, in this study, N, P-NiSe nanoelectrode materials were prepared using nickel foam as the nickel source and hexachlorocyclotriphonitrile as the nitrogen and phosphorus dopant using an efficient, energy-saving, and simple microwave method. It was also characterised by XRD and XPS to confirm the successful preparation of N, P-NiSe materials. In addition, the material yielded a high capacitance value (3184 F g−1) and good cycling stability (72% of the initial capacitance value was retained after 4000 cycles) in electrochemical tests. To demonstrate its excellent suitability for practical applications, an asymmetric supercapacitor was assembled using N, P-NiSe as the anode and activated carbon as the cathode. At an operating voltage of 1.6 V, the device achieved an energy density of 289.06 Wh kg−1and a power density of 799.26 W kg−1and retained 80% of its initial capacity after 20,000 cycles.

The objective of this present study is to evaluate the effect of different drying methods (spray drying, freeze drying and hot-air drying) on physicochemical properties and antioxidant ability of G. lucidum extracts (GLEs) using various techniques. Meanwhile, combined with free amino acids (FAA) analysis, taste activity values (TAV) analysis and electronic tongue to investigate the relationship between the drying method and the sensory quality of GLEs. The study demonstrates that spray drying GLEs (SDE) has a high water solubility of 96.04% ± 0.10% due to its low crystallinity and hollow spherical microstructure. SDE and freeze drying GLEs (FDE) contain high levels of polysaccharides and proteins, which facilitates the formation of polysaccharide-protein chelates, thereby improving antioxidant capacity. However, SDE has higher antioxidant activity when its polysaccharide content is the same. SDE has higher thermal stability to maintain the molecular structure of GLEs. Meanwhile, FDE has a bitter FAAs content up to 65.84 ± 1.12 mg/g and TAV of Histidine is 178.70. Overall, the results suggest that spray drying is an appropriate and preferred drying method to maintain the bioactivity and bioavailability of GLEs. These findings may enhance the understanding of the GLEs flavor property and bioavailability associated with drying methods and provide a theoretical basis for G. lucidum processing.

Background Acetaminophen, a widely used analgesic and antipyretic drug, has become a significant aquatic micro-pollutant due to its extensive global production and increased consumption, particularly during the COVID-19 pandemic. Its high-water solubility leads to its pervasive presence in wastewater treatment plants (WWTPs), posing substantial risks to the environment and human health. Biological treatment is one of the promising approaches to remove such pollutants. Although previous studies have isolated acetaminophen-degrading pure cultures and proposed catabolic pathways, the interactions between microbiotas and acetaminophen, the distribution feature of acetaminophen degradation genes, and the gene-driven fate of acetaminophen in the real-world environment remain largely unexplored. Results Among the water samples from 20 WWTPs across China, acetaminophen was detected from 19 samples at concentrations ranging from 0.06 to 29.20 nM. However, p -aminophenol, a more toxic metabolite, was detected in all samples at significantly higher concentrations (23.93 to 108.68 nM), indicating the presence of a catabolic bottleneck in WWTPs. Metagenomic analysis from both the above 20 samples and global datasets revealed a consistently higher abundance of initial acetaminophen amidases compared to downstream enzymes, potentially having explained the reason for the bottleneck. Meanwhile, a close correlation between initial amidases and Actinomycetota revealed by genome-based taxonomy suggests a species-dependent degradation pattern. Additionally, a distinct amidase ApaA was characterized by newly isolated Rhodococcus sp. NyZ502 (Actinomycetota), represents a predominant category of amidase in WWTPs. Significant phylogenetic and structural diversity observed among putative amidases suggest versatile acetaminophen hydrolysis potential in WWTPs. Conclusions This study enhances our understanding of acetaminophen’s environmental fate and highlights the possible occurrence of ecological risks driven by imbalanced genes in the process of acetaminophen degradation in global WWTPs.

In the quest to bolster the electrochemical efficiency of metal oxide electrodes for high-performance hybrid supercapacitors, the integration of phosphorus doping emerges as a pivotal method. This study delves into the fabrication process of a specialized P-CNT on Cu–ZnO/NPC composite through a meticulous in-situ synthesis followed by phosphating. The strategic incorporation of phosphorus heteroatoms orchestrates a profound alteration in the electronic structure of the Cu–ZnO/NPC matrix, effectively augmenting its storage capabilites. The electrode showcases a commendable specific capacitance of 1619C/g. Making this innovation into a hybrid supercapacitor configuration (P-CNT@Cu–ZnO/NPC //activated carbon) yields an impressive energy density of 56.13 Wh/kg at 1250 W/kg. Even after enduring 10,000 exhaustive testing cycles, the device remarkably retains 98.0 % of its initial capacitance, affirming the resilience and enduring performance of this tailored design. In oxygen evolution reaction (OER) application, the P-CNT@Cu–ZnO/NPC electrode demonstrated 43.26 mV/dec tafel slope. These groundbreaking findings underscore the transformative potential of the P-CNT@Cu–ZnO/NPC composite in shaping the landscape of future energy storage electrode materials.

Probing the spatial separation and transport process of photogenerated charges at nanoscale interfaces is essential for understanding catalytic reaction mechanisms on heterostructure photocatalysts. Here, we developed a p-n junction Na 0.6 CoO 2 /g-C 3 N 4 S-scheme photocatalyst via electrostatic self-assembly technology. A significant hydrogen production rate of ∼ 0.294 mmol g − 1 h −1 was achieved on the optimal Na 0.6 CoO 2 /g-C 3 N 4 , which was ten times higher than that of pure g -C 3 N 4 . In-situ XPS shows that the electrons in Na 0.6 CoO 2 / g -C 3 N 4 had different flow directions without and with illumination, demonstrating a built-in electric field being formed through Na 0.6 CoO 2 and g -C 3 N 4 interaction. DFT calculations and ultraviolet photoelectron spectroscopy verified that g -C 3 N 4 and Na 0.6 CoO 2 possess the energy band structures conforming to the heterostructure of S-scheme. In-situ Kelvin probe microscope studies show that Na 0.6 CoO 2 and g -C 3 N 4 both have a self-induced electric field effect, and their combination significantly strengthens the built-in electric field and improves the space separation of photogenerated electrons. Compared with the change of the surface photovoltage of g -C 3 N 4 (60 mV) and Na 0.6 CoO 2 (−30 mV), the average surface contact potential difference of Na 0.6 CoO 2 / g -C 3 N 4 reached 320 mV, yielding a higher efficiency of photogenerated electron separation. This work also provides direct evidence on the existence of a built-in electric field and an electron flow direction for heterostructure photocatalyst materials.

The persistent contamination of aquatic environments by tetracycline (TC) necessitates advanced remediation strategies. Herein, a ternary Fe–O–P-co-modified graphitic carbon nitride (FOPCNx) was synthesized via structural integration of Fe–N2 configurations with O/P dual doping for efficient TC degradation in a solar-driven photo-Fenton system. This study pioneers the synergistic coupling of Fe–N2 coordination and heteroatomic O/P substitution to optimize charge dynamics. Comprehensive characterization confirmed the formation of Fe–N2 active sites and aromatic structures incorporated with the aromatic group, which collectively enhanced visible-light absorption, suppressed electron–hole recombination, and facilitated charge carrier redistribution. The optimized FOPCN2 demonstrated exceptional photoelectric efficiency (3.7-fold higher photocurrent density than pristine g-C3N4) and achieved 98.9% TC removal within 40 min of irradiation with a kinetic constant of 0.113 min–1, outperforming conventional systems. Mechanistic studies revealed dual enhancement pathways: Fe–N2 sites promoted electron transfer and Fe(III)/Fe(II) cycling, while the O/P dual doping enabled electron delocalization for improved charge mobility. The system exhibited remarkable pH adaptability (3–7), robust resistance to inorganic anions, and universal degradation capability for mixed organic pollutants. Three TC degradation pathways were identified through intermediate analysis, with radical trapping and EPR verification confirming the dominant roles of •OH, e–, and O2•–. This work provides critical insights into structure–activity relationships for carbon nitride modification, establishing a paradigm for designing multifunctional photocatalysts for antibiotic-contaminated wastewater remediation.

An electrolytic Zn–MnO2 battery is highly valued due to its cost-effectiveness, environmental friendliness, and abundant resource availability. However, the battery’s performance is hindered by the slow kinetics at the poorly conductive MnO2 cathode and hydrogen evolution at the Zn anode. Here, a strategy of P–O–M (M = Mn, Zn) d-pπ backbonding design is proposed for phosphorus–oxygen electrolyte additives, which can be realized by tuning the atomic dipole moment-corrected Hirshfeld (ADCH) population charge of the P/O atom. The reversibility of d-pπ backbonding not only leads to the fast kinetics of Mn2+/Zn2+ at electrodes during both charge and discharge processes to suppress the competitive hydrogen evolution reaction but also enhances the electronic conductivity at the electrode–electrolyte interfaces to sustain the high areal capacity of batteries. Hydroxymethyl dimethyl phosphite (HPD) with d-pπ backbonding is a preferred additive with a suitable ADCH charge. The assembled electrolytic Zn–MnO2 (HPD) battery exhibits a high discharge capacity of 14.05 mAh cm–2 at an areal capacity of 15 mAh cm–2 and superior cycling stability over 1500 cycles. The Zn–MnO2 (HPD) soft-pack battery exhibits a discharge capacity of over 1.60 Ah at a discharge rate of 0.5 C and maintains a Coulombic efficiency of ∼80% over 100 cycles. Furthermore, the assembled 50 V 40 Ah commercial Zn–MnO2 (HPD) battery can drive an electric vehicle for 10 km. The ADCH charge regulation provides a feasible and effective method for developing high-performance aqueous batteries by achieving d-pπ backbonding.

High-efficiency electromagnetic interference (EMI) shielding fabrics with strong absorption and low reflection characteristics are urgently demanded to address the increasing electromagnetic radiation pollution, but it is still challenging to integrate these features onto single fabric. Herein, an all-in-one asymmetric conductive structure was constructed on 3D polyester fiber-based spacer fabric through a successive in situ polymerization of polyaniline and followed by localized electroless Ni–P plating process. Thanks to the synergistic effect of microwave absorbing layer of low-conductivity polyaniline coating and shielding reflection layer of highly conductive Ni-P plating, the incident electromagnetic waves undergo a process of “absorption–reflection–reabsorption” and are dissipated as much as possible when they propagate into the composite fabric. The resultant composite fabric shows a superior EMI SE over 60 dB within 18–40 GHz, whereas the EMI SE from reflection is only 1.6 dB, and the average reflectivity is as low as 0.31, which indicates that 69% of electromagnetic waves are absorbed in the fabric. Interestingly, the porous structure of substrate and highly conductive Ni–P plating also endow this fabric with good thermal insulation and low infrared emissivity, resulting in an excellent infrared stealth performance. This study provides a facile and feasible approach for the development of high-efficiency and multifunctional EMI shielding fabric with low-reflection characteristics that holds great promise for application in civil and military fields.

The exploration of high-performance and multifunctional catalysts is a key issue in Zinc-air/iodide hybrid battery (ZAIHB). In this study, iron‑cobalt dual atomic sites (DAS) embedded in a biomass-derived (N, P) heteroatom-codoped carbon nanobelt (NPCB) framework were designed as a multifunctional catalyst for ZAIHB. Theoretical analysis reveals that the structure matching on both dual-atomic-centers and local electronic engineering contribute to the promoted catalytic activities for oxygen and iodide redox reactions. In addition, the nitrogen (N)-, and phosphorus (P)-codoped carbon nanobelts contributed to the highly porous and freestanding substrate, which endowed rapid kinetics. Benefiting from the above advantageous features, FeCo DAS@NPCB exhibits the excellent multifunctional catalytic properties for oxygen/iodide redox reactions. The full ZAIHB battery with the FeCo DAS@NPCB cathode exhibited high energy efficiency (77.4 %) and a long cycle life (over 300 h). Moreover, the solid-state ZAIHB with a hydrogel electrolyte showed good flexibility and stability during charge/discharge cycling. More impressively, the cell shows high reliability during the transition from exposure to air to an oxygen free environment with the replacement of oxygen reduction reaction (ORR) by iodide reduction reaction (IRR). This unique mechanism results in the high adaptability of the fabricated ZAIHB to serve multifarious working environments. Therefore, this study introduces a novel strategy for the design and construction of multifunctional catalysts, and promotes the rapid development of highly efficient ZAIHB for diverse electronics.

Carbon aerogel, as a novel porous adsorbent material, is highly promising for use in adsorption of volatile organic compounds (VOCs) from industrial exhaust emission. In this study, cellulose was used as a carbon precursor. A green, effective biomass carbon aerogel (BCA/Six-F127y) with an ultrahigh specific surface area and high adsorption performance was prepared by a combined soft template–chemical activation method. Results showed that the optimal material BCA/Si0.50-F1270.25 had a layered micro-/mesoporous structure with a specific surface area of up to 1966.03 m2 g–1 and a total pore volume of 1.38 cm3 g–1, which exhibited highly efficient adsorptive removal of gaseous p-xylene. The maximum theoretical adsorption capacity was 540.54 mg g–1. The main adsorption mechanisms are microporous filling, hydrogen bonding, and π–π conjugation. Therefore, this study expands the application prospect of carbon aerogels in the field of adsorption and provides a reference for industrial VOC pollution control.
