Protective coatings containing corrosion inhibitors (CIs) are commonly used to address this natural process, particularly severe in immersed structures in seawater. However, high-performance CIs, such as benzotriazole (BTA), often exhibit toxicity towards aquatic organisms and leach prematurely. This study introduces safe and sustainable-by-design engineered nanomaterials, specifically layered double hydroxides loaded with BTA (Mg-Al LDH-BTA and Zn-Al LDH-BTA), as an innovative and eco-friendly approach compared to state-of-the-art CIs. This study aims to characterize both nanomaterials, assess their anti-corrosion performance when incorporated in polyurethane coatings, and evaluate their environmental behavior when dispersed in water, short-term acute and chronic effects on temperate marine species, and the environmental hazard. Key findings include a superior anti-corrosion performance of coatings containing Zn-Al LDH-BTA compared to BTA-coatings. Aqueous dispersions of nanomaterials exhibit instability of particle size and zeta potential over time, while concentrations of metals (Al, Zn) and nitrates reach high levels in the highest tested concentration due to partial dissolution, which may explain the observed toxicity patterns (median effect concentrations in the mg/L range). The tested compounds were not toxic for most tested species, apart from bacteria (<em>Aliivibrio fischeri</em>) and/or echinoderms (<em>Paracentrotus lividus</em>) and, in case of Mg-Al LDH-BTA, also on two microalgae species. The highest statistical PNEC value was observed for Mg-Al LDH-BTA (PNEC=0.326 mg BTA/L), while the highest deterministic PNEC value was found for Zn-Al LDH-BTA (PNEC=0.00041 mg BTA/L). These findings indicate that both nanomaterials are environmentally sound and efficient alternatives for anti-corrosion maritime applications.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"447 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further elucidate the mechanism of curcumin in human CRC treatment, we hypothesized that HPSE plays a pivotal role in human CRC metastasis and that curcumin inhibits this process by downregulating HPSE expression through epigenetic regulation mediated by non-coding RNAs. For further research, human CRC cells were infected with lentivirus to establish overexpression of HPSE cell lines and corresponding negative control cell lines. In vitro and in vivo experiments showed that curcumin inhibited the proliferation, migration, and metastasis of CRC cancer by inhibiting HPSE expression. In the tumor microenvironment, HPSE played an important role in activating the IL-6/STAT5 axis signaling pathway by destructing the extracellular matrix and releasing large number of cytokines, while changing the tumor microenvironment and EMT process, thus promoting tumor metastasis. RNA-seq analysis combined with qRT-PCR results showed that curcumin's inhibition of HPSE expression involved the regulation of non-coding RNAs. Taken together, our results suggested that HPSE promotes CRC metastasis by activating the IL-6/STAT5 signaling axis, disrupting the ECM, releasing cytokines, and altering the tumor microenvironment to facilitate EMT. Curcumin significantly inhibits CRC cell proliferation, migration, and metastasis by downregulating HPSE expression via non-coding RNAs, which related to IL-6/STAT5 axis signal pathways. This research provides a comprehensive understanding of the molecular mechanisms underlying curcumin's anti-CRC effects, emphasizing the role of HPSE and non-coding RNAs in tumor metastasis.

RH biochar (RHB) is generally used for soil amelioration; however, its functionality can be further enhanced by tailoring its properties to meet the specific requirement of crops. Herein, we report that the conversion of RHB to its nanoform (hereafter termed as NRB) and employing surface engineering could enable its use as a slow-release carrier for the delivery of micronutrients to plants. We used Zn , a key plant micronutrient, to study its effect in rice seedling growth. The results showed that the Zn loaded functionalized biochar (Zn-FRB) contributed to the enhanced root and shoot growth of rice compared to that of NRB. Zn-FRB at a high concentration (100 µg mL-1) showed ~11% increase in the soluble protein content. Zn-FRB (30 and 200 µg mL-1) also showed reduction in antioxidative enzyme activity (CAT and APX) compared to that of NRB suggesting an imperative role of Zn in protecting against oxidative damage of membrane lipids. Zn-FRB application caused a change in expression of Zn homeostasis genes and phloem transporter gene and increased their transcript levels as revealed by qPCR studies. According to these results, Zn-FRB was found to be more effective than NRB in enhancing the plant growth, reducing the oxidative damage and transportation of Zn. These results suggest the potential of this approach as new slow delivery system of micronutrients to plants.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"19 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research focused on evaluating the efficacy of Peroxydisulfate (PDS) activation by CoNiFc-MOF catalyst for the removal of emerging contaminants. The results indicated that the CoNiFc-MOF catalyst achieved a removal efficiency exceeding 98% for 10 mg/L bisphenol A (BPA) within a 5 min timeframe. The activation mechanism of PDS was elucidated through electron paramagnetic resonance (EPR), revealing the involvement of both radical and non-radical oxidation pathways. In this non-radical mechanism, BPA undergoes oxidation via a direct electron transfer pathway facilitated by the metastable reaction complex (CoNiFc-MOF/PDS*). The CoNiFc-MOF catalyst demonstrated a high removal efficiency, consistently maintaining over 90% efficiency across five consecutive cycles, indicative of its remarkable catalytic activity and stability. The intermediates of BPA were further identified using liquid chromatography-mass spectrometry (LC-MS), leading to the proposal of four potential degradation pathways. The catalyst also proved high efficacy in the removal of bisphenol B (BPB), tetracycline (TC), oxytetracycline (OTC), with the reaction rate being closely associated with its structural characteristics and properties. Moreover, the CoNiFc-MOF catalyst is notable for its straightforward synthesis process and low cost, offering a promising design strategy for the development of efficient PDS-activated catalytic materials.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"15 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we assessed the developmental toxicity of ethidium bromide-based covalent organic frameworks (EB-COFs) in rice (<em>Oryza sativa</em>) seedlings in hydroponic culture. Seedlings were exposed to EB-COFs at concentrations ranging from 0.1 to 1000 mg L<small>⁻¹</small> for 14 days. Shoot length, fresh weight, total chlorophyll content, and photosynthetic rate were unaffected at 100 to 1000 mg L<small>⁻¹</small>; however, root length was significantly inhibited, particularly at 1000 mg L<small>⁻¹</small>, where oxidative damage was observed in roots. To elucidate underlying mechanisms, we performed transcriptomic and metabolomic profiling on roots exposed to 1000 mg L<small>⁻¹</small> EB-COFs. Differentially expressed genes (DEGs) involved in development and stress responses, for example, <em>WRKY24</em>, were found to be upregulated. Metabolomic profiling identified 1190 differentially accumulated metabolites (DAMs), including key compounds involved in oxidative stress response and root development such as ferulic acid and <em>p</em>-coumaric acid. Pathway enrichment analysis revealed that EB-COFs primarily affected phenylpropanoid biosynthesis, glutathione metabolism, and tryptophan metabolism, which are critical for root growth and stress defense. Our study provides the first comprehensive demonstration that EB-COFs selectively impair rice root growth by inducing oxidative stress and perturbing key metabolic and signaling pathways. These results suggest that future environmental safety assessments of COF materials should include their potential impact on plant health, particularly focusing on oxidative stress and root development.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"54 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamics of NPs' fate and the interplay between NPs and organisms make it challenging to perform accurate and process-based hazard and risk characterization. It's crucial to use NPs' concentrations after they are transported and transformed for risk assessment (i.e., evaluating the fate of NPs). This will provide more accurate results than using the mass of released NPs. However, experimental limitations make it challenging to directly quantify and track NPs. Hence, using mathematical models to simulate NPs' fate has become a promising alternative, but previous reviews lack systematically evaluated these models' strengths and weaknesses. This review is the first to analyze and evaluate NPs' fate models from a mathematical perspective. It discusses the calculation methods and parameters for quantifying transport processes and transformation reactions of NPs in environmental compartments (including water, soil, sediment, and atmosphere) used by different models, sorts out and compares these processes in each compartment. Besides, this study provides recommendations for the further development of NPs' fate models and proposes an optimal modeling procedure for simulating the fate of NPs. The procedure provides the optimal simulation equations and parameters for each transport and transformation process in each compartment, intending to quantify these processes and NPs' fate considering explicitly knowledge of uncertainties. Furthermore, we provide suggestions for constructing fate models for novel NPs and applying machine learning in fate models, to improve NPs' fate models and environmental risk assessment.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"58 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dimethylformamide significantly influenced the reaction kinetics of Bi<small>₂</small>MoO<small>₆</small> by coordinating with Bi<small>³⁺</small> ions and modulating their release rate during the solvothermal process.

This significant enhancement in photocatalytic performance was caused by the surface plasmon resonance (SPR) effect of Bi metal with the presence of oxygen vacancies, both of which promote charge carrier separation. Additionally, Bi metal functioned as a cocatalyst similar to noble metals, further improving the photocatalytic efficiency. The Z-scheme heterojunction was constructed based on well-matched energy band positions, while the integrated electric field provided the driving force for the reaction. Consequently, the Z-scheme heterojunction enhanced photoinduced charge carrier transfer and suppressed electron–hole recombination. Furthermore, potential CIP degradation pathways were investigated using Fukui function analysis and LC-MS. This study demonstrates the feasibility of enhancing photocatalytic efficiency by employing inexpensive Bi metal as a cocatalyst, offering a cost-effective alternative to precious noble metals.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"21 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
