Excess phosphorus in aquaculture wastewater is prone to pose a dual threat to ecological and economic benefits. This study is a simple and low-cost biomolecule-reinforced biochar composite based on three plant extracts with the ability to remove total phosphorus (TP) in real wastewater. Various analyses of the three plant extracts were conducted to understand the differences in TP removal efficiency and identify the differences in the functional groups on their surfaces. The results indicated that plant extracts derived from Excoecaria cochinchinensis Lour (Ec), Green tea (GT), and Pinus massoniana Lamb (PML), were rich in oxygen-containing functional groups, amino and carboxyl groups, and rich in organic acids, respectively. These results revealed differences in adsorption efficiency of the three materials. Among the three biochars obtained by plant modification, P -biochar 3, showed a superior TP removal capacity with a removal efficiency at 70.9 %. The kinetic analysis of its adsorption behavior followed a pseudo-second-order model (R 2 = 0.992), suggesting that the chemisorption mechanism was dominant. Advanced characterization also identified the enhancement of its oxygen-containing functional molecules, facilitating the interaction with phosphate species. Meanwhile, P -biochar 3 maintained a TP removal efficiency above 55.45 % in a real eel aquaculture wastewater column experiment, and it could remove multiple pollutants. This study demonstrates that functionalization of plant extracts is a viable strategy for the development of sustainable adsorbents capable of addressing nutrient pollution in various agricultural wastewater streams.

To explore the effect of sensor structure on anions detection, three new hydrazones P-CN , P-CF 3 and P-NO 2 having different electron-withdraw groups are synthesized. Their anions recognition properties are investigated compared with those of P-OMe , P-H and acylhydrazone B-NO 2 . It shows all non-nitro hydrazones exhibit increasing sensitivity specifically toward CN − in the order of P-OMe < P-H < P-CN < P-CF 3 , indicated by color change from colorless to different shades of blue. Whereas P-NO 2 responds to CN − , F − and H 2 PO 4 − concurrently and its sensitivity to CN − is more than 4 times higher compared with that of the other hydrazones. CN − can be discriminated from F − by P-NO 2 in acetonitrile/water. On the other hand, B-NO 2 has only discernible response to CN − and F − with less sensitivity than P-NO 2 does. Detection details of P-NO 2 to CN − are investigated by titration, anti-interference tests, Job’s plot, HRMS, pH effect assays. The 1 H NMR, IR and reversibility tests demonstrate the deprotonation mechanism. The detection mechanisms of P-NO 2 and B-NO 2 to CN − are compared and demonstrate the reason of their recognition difference. The detection limits of P-NO 2 to CN − , F − and H 2 PO 4 − in acetonitrile are 0.0477 μM, 0.0876 μM and 1.46 μM, respectively. Hence, this work indicates that strong electron-withdraw group in related probes can improve their anion detection ability, meanwhile conjugation effect should be also considered in structure designing.

Photonic synaptic transistors, designed to emulate the multispectral light detection of retinal neurons, play a pivotal role in advancing artificial vision systems capable of full-color image recognition. However, their limited sensitivity to weak and multispectral light significantly hampers their application in full-color image capture and recognition. In this work, a p-i-n structured synaptic transistor is introduced that improves weak light sensitivity and enhances synaptic performance by addressing interface issues. By integrating P3HT/LiF/InZnGdO nanofibers as p-i-n structure, the spectral response is successfully broadened from visible to near-UV region, achieving sensitivity to light intensities as low as 0.05 mW cm −2 . The device exhibits remarkable PPF characteristics across the wavelength range of 395–633 nm, with the PPF index showing a maximum increase of 84% compared to the single InZnGdO nanofiber device. Additionally, multiple neural networks are constructed with data from the synaptic transistor array driven by wavelength-tunable synaptic plasticity to validate the device's feasibility in various application scenarios. The proposed device achieved a recognition accuracy of up to 95.26% for high-precision full-color images based on the public CIFAR-10 dataset. This p-i-n structure offers a novel pathway to enhance the synaptic performance of metal oxide-based synaptic transistors, advancing the development of next-generation artificial vision.

Due to restrictive linear relationship between intermediates in adsorption evolution mechanism (AEM) of oxygen evolution reaction (OER), a higher overpotential must be overcome for conversion of *O to *OOH. Activating lattice oxygen mechanism (LOM) can address the AEM’s challenges by facilitating O-O coupling. However, via LOM pathway, extracting electrons from metal-oxygen (M−O) bonds usually results in structural instability. Herein, we propose an effective method to stabilize LOM-catalysts by combining cerium dioxide with cobalt phosphide (CeO 2 /CoP heterostructure). CeO 2 acts as an electron buffer to retain/provide electrons at different stages, while CoP with strong Co-P covalency enhances structural/catalytic stability in strongly-alkaline conditions. CeO 2 /CoP exhibits an OER overpotential of only 225 mV at 10 mA cm −2 . Initially, CeO 2 acquires electrons from CoP to accelerate surface reconstruction and form high-valence Co δ+ (CoOOH). Then, CoOOH acquires electrons from the 4 f -orbital of Ce through the Ce-O-Co interface, rather than from the M−O bond, thus ensuring OER stability. For water splitting, bifunctional CeO 2 /CoP-assembled electrolyzer requires a cell-voltage of only 1.54 V to achieve 10 mA cm −2 and retains 89.5 % of its activity after 72 h of cycling. It highlights that leveraging electron-buffering metal species can enhance the LOM stability, thereby enabling its application in bifunctional electrocatalysis.

Carbon nitride (g-C 3 N 4 ) photocatalysts face significant challenges in environmental water remediation, including limited visible light absorption, severe charge recombination, and slow charge transfer. To address these limitations, we developed a Z-scheme Ni-C 3 N 4 /P-C 3 N 4 heterojunction using an efficient and environmentally friendly ball milling method. Compared to g-C 3 N 4 , P-C 3 N 4 , and Ni-C 3 N 4 , the Ni-C 3 N 4 /P-C 3 N 4 heterojunction demonstrated significantly enhanced photocatalytic activity, achieving 99.1% and 86.8% degradation of tetracycline (TC) and rhodamine B (RhB) within 60 minutes, respectively. The total organic carbon (TOC) removal efficiencies were 78.2% for TC and 71.8% for RhB. This enhanced activity is attributed to the optimized heterojunction components and the tightly coupled heterojunction interface, which improve charge transfer and promote efficient separation of photogenerated carriers. Radical scavenging experiments and electron spin resonance (ESR) analysis revealed that holes (h⁺), hydroxyl radicals (·OH), and superoxide radicals (·O 2 − ) all synergistically contribute to the degradation process, with ·O 2 − being the dominant active species. Additionally, toxicity assessment of the degradation products confirmed the environmental safety of the photocatalytic process. This study provides a promising strategy for photocatalytic water purification and offers valuable insights into the design of heterojunction materials.

The combination of radiotherapy and immune checkpoint blockade (ICB) therapy has demonstrated considerable efficacy in oncological treatment. However, the clinical PD-L1 antibody (anti-PD-L1) for glioblastoma (GBM) imprecisely accumulated in intracranial radiotherapy target and is often compromised by the formidable blood-brain barrier (BBB). To address these challenges, the study innovatively engineers a hierarchical precision delivery nanoplatform (FB-aPD-L1). This nanoplatform leverages sulfated fucoidan, which exhibited targeted affinity for P-selectin, an adhesion molecule expressed with spatiotemporally restricted specificity in response to radiotherapy. Following precise capture FB-aPD-L1 and crossing BBB, there is ultrasensitive release of BPA 4 -aPD-L1 and fucoidan in the tumor microenvironment. The targeted conjugation of 5-borono-2-pyridinecarboxylic acid (BPA) and sialic acid (SA) augmented tumor-specific targeting and retention of anti-PD-L1, while fucoidan reprogrammed the immune microenvironment, thereby synergizing with the anti-PD-L1 to increase CD8 + T cell infiltration and enhance radio-immunotherapy efficacy. This work exemplifies a novel paradigm for brain-targeted precise drug delivery.

A family of well-defined poly(3-hexylthiophene)-b-poly(5,8-di-p-tolylquinoxaline-2,3-diyl) rod–rod block copolymers was designed and synthesized in one pot via mechanistically distinct, sequential living polymerization using Ni(dppp)Cl2 as a single catalyst. The block copolymerization was demonstrated to proceed in a living/controlled chain-growth manner, affording the desired block copolymers in high yields with tunable compositions, controlled molecular weight, and narrow molecular weight distributions. The resulting block copolymer was revealed to self-assemble into various well-defined supramolecular structures depending on the solvents used such as nano-fibril and spherical nanoparticles. Very interestingly, such a block copolymer displayed highly selective visual detection for cobalt over most other competing metal ions by changing its orange color to light green and bright orange emission to deep green. The detection limit was estimated to be down to 1.0 × 10−7 M and the interference of the other competing metal ions is negligible. Furthermore, such a block copolymer can be applied using test strips, making it a practical, sensitive, and selective probe for cobalt ions.

Cadmium indium sulfide (CdIn2S4), a widely used n-type semiconductor, has been considered a promising photoanode material for photoelectrochemical (PEC) water splitting due to its excellent light response characteristics and suitable energy levels. However, its application in the PEC field is limited by rapid carrier recombination on the surface and severe photocorrosion phenomena. In this study, a novel strategy is proposed by loading Cu2S onto the surface of CdIn2S4 via an ultrasound-assisted method to modify the CdIn2S4 photoanode. As a p-type semiconductor, Cu2S forms a p–n heterojunction with CdIn2S4, creating an internal electric field that facilitates charge transport. Additionally, the Cu2S overlayer acts as a cocatalyst, enhancing the surface reaction kinetics and improving the charge injection efficiency at the photoelectrode/electrolyte interface. The incorporation of Cu2S also reduces the photocorrosion on the CdIn2S4 surface. Experimental results demonstrate that the optimal Cu2S/CdIn2S4 photoanode exhibits a photocurrent of up to 0.3 mA cm−2 at 1.23 V versus the reversible hydrogen electrode, approximately ten times higher than that of bare CdIn2S4. This work offers an effective approach to modulate carrier dynamics, thereby enhancing the PEC performance of photoanodes.

Oxygen vacancy-enriched N/P co-doped cobalt ferrite (NPCFO) was synthesized using ionic liquid as N and P sources, and then the catalytic performance and mechanism of NPCFO upon peroxymonosulfate (PMS) activation for the degradation of organic pollutants were investigated. The as-synthesized NPCFO-700 exhibited excellent catalytic performance in activating PMS , and the degradation rate constant of 4-chlorophenol (4-CP) increased with the increase of OV concentration in NPCFO-x. EPR analysis confirmed the existence of · OH, SO 4 ·- , and 1 O 2 in the NPCFO-700/PMS system, in which OV could induce the generation of 1 O 2 by PMS adsorption and successive capture, and also served as electronic transfer medium to accelerate the redox cycle of M 2+ /M 3+ (M denotes Co or Fe) for the generation of radical to synergistically degrade organic pollutants. In addition, the contribution of free radical and nonradical to 4-CP degradation was observed to be strongly dependent on solution pH, and SO 4 ·- was the major ROS in 4-CP degradation under acid and alkaline condition, while 1 O 2 was involved in the degradation of 4-CP under neutral condition due its selective oxidation capacity, as evidenced by the fact that such organic pollutants with ionization potential (IP) below 9.0 eV were more easily attacked by 1 O 2 . The present study provided a novel insight into the development of transition metal-based heterogeneous catalyst containing massive OV for high-efficient PMS activation and degradation of organic pollutants.

Mucus clearance, epithelium mucosal barrier and P-glycoprotein (P-gp) efflux are the main gastrointestinal barriers that limit the oral delivery of nanoparticles. Inspired by tunable particles surface properties-dependent trans -mucus and trans -mucosal abilities, novel bilayer-functionalized mesoporous silica nanoparticles (MSN) containing D- α -tocopheryl polyethylene glycol succinate (TPGS) and sulfobetaine 12 (SB12) were designed by layer-to-layer assembly. The amino-grafted MSN (MSN-NH 2 ) was firstly functionalized with TPGS as hydrophobic layer (MSN-TPGS), and then SB12 was self-assembled on the hydrophobic surface of MSN-TPGS to generate a neutral and hydrophilic MSN (MSN-TPGS@SB12). Compared with MSN-NH 2 , MSN-TPGS, and MSN-TPGS@P123, the MSN-TPGS@SB12 possessed “one stone three birds” functions that enhanced mucus penetration, increased trans -mucosal absorption, as well as suppressed P-gp efflux. The pharmacokinetics study demonstrated that the MSN-TPGS@SB12 loading puerarin (MSN-TPGS@SB12-PUE) exhibited much higher bioavailability compared to other PUE-loaded formulations. Furthermore, the MSN-TPGS@SB12-PUE could significantly enhance the anti-inflammatory efficacy of PUE in vitro and in vivo . In summary, bilayer-functionalized MSN-TPGS@SB12 is a promising vehicle for overcoming the multiple gastrointestinal barriers (mucus clearance, intestinal epithelium barrier and P-gp efflux). Meanwhile, this study also provides a better understanding of the importance of tunable surface property of MSN on oral delivery of drugs.

Fenoxaprop-P-ethyl (FE) can effectively control weeds in rice fields, but it has been found to cause phytotoxicity in rice. In this study, the phytotoxicity of FE was mitigated by perilla leaf essential oil (PEO) in rice seedlings. The injury recovery rates (IRRs) for shoot length and fresh weight treated with 800 mg/L of PEO were 101.51% and 99.05%, respectively. Moreover, the damage ofs-metolachlor and pretilachlor was also alleviated when co-applied with 800 mg/L PEO; the IRR ofs-metolachlor phytotoxicity was 26.07% and 27.34%, respectively, and the IRR of pretilachlor phytotoxicity was 127.27% and 124.39%, respectively. However, PEO had no significant effect on the phytotoxicity of pinoxaden, mesotrione, penoxsulam, mesosulfuron-methyl, and nicosulfuron. The results of GC–MS analysis showed that a total of 23 components were detected in PEO, among which linalool (36.49%), linalyl formate (26.96%), α-terpineol (10.63%), 2-hexanoylfuran (5.81%), geranyl acetate (4.13%), and neryl acetate (2.30%) were the primary components. Among them, 2-hexanoylfuran was the most effective component to alleviate FE damage, for which the IRR of shoot length and fresh weight was 73.17% and 73.02%, respectively, followed by the geranyl acetate, for which the IRR was 72.32% and 60.56%, respectively, and neryl acetate, for which the IRR was 65.28% and 58.11%, respectively. Furthermore, the application of 50 mg/L of 2-hexanofuran significantly improved the tolerance of shoot length and fresh weight to FE stress by factors of 5.32 and 5.35, respectively. This research demonstrates that PEO and 2-hexanoylfuran have the potential to serve as natural safeners to reduce phytotoxicity.

A novel magnetic organic porous polymer (denoted as Fe 3 O 4 @PC-POP) was developed for magnetic solid-phase extraction (MSPE) of two gastric cancer biomarkers (P-cresol and 4-hydroxybenzoic acid) from urine samples prior to high-performance liquid chromatographic analysis. The adsorbent was characterized by scanning electron microscope, transmission electron microscope, FTIR, powder X-ray diffraction, and other techniques. The result of dynamic light scattering shows that the particle size of the adsorbent is mainly distributed around 400 nm. Based on the design concept of the Fe 3 O 4 @PC-POP, the proposed material can effectively capture the target analytes through electrostatic and hydrophobic interaction mechanism. Furthermore, the enrichment conditions were optimized by the response surface method, and the method was utilized for the determination of P-cresol and 4-hydroxybenzoic acid in real urine samples from health and gastric cancer patients with high enrichment factors (34.8 times for P-cresol and 38.7 times for 4-hydroxybenzoic acid), low limit of detection (0.9–5.0 μg L −1 ), wide linear ranges (3.0–1000 μg L −1 ), satisfactory relative standard deviation (2.5%–8.5%), and apparent recoveries (85.3–112% for healthy people’s and 86.0–112% for gastric cancer patients’ urine samples). This study provides a guided principle for design of the versatile polymer with specific capturing of the target compounds from complex biological samples.
