We present Ni-SiC nanocomposite coatings as potential substitutes and conduct a comprehensive investigation into the impact of impregnated SiC particles on coating properties. Specifically, we examined the aging of Ni-watt type and Ni Watt-SiC nanocomposite coatings in various environmental and biological media. Our release and transformation data indicate an enhanced release and transformation of Ni in the simulated media (e.g., up to 200 μg/mL in cell culture media) and the formation of NiO and Ni (OH)₂ species as confirmed by XPS analysis. Transmission electron microscopy data reveals the release of SiC NPs in the respective simulated aging medium. The Ni ion release from Ni-watt type and Ni-SiC nanocomposite coating was also investigated in silico to support safe-by-design (SbD) approaches in the development of nanoalloys for electroplating. An invitro cytotoxicity assay, according to ISO shows a significant reduction in cell viability for Ni-SiC nanocomposite coated samples (up to 80% after 72 hours) compared to standalone Ni-Watt type electroplated coatings (up to 20% after 72 hours). Our findings suggest that the co-deposition of Ni with SiC NPs enhances Ni release, which is a major factor in causing toxicity. These results could be pivotal in the adoption of Safe and Sustainable by Design principles within the electroplating industry. This paper contributes to the fields of nanotoxicology and surface coatings, providing a foundation for designing and optimising environmentally friendly, high-performance coatings with broad industrial applications","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"72 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599955","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}

This review focuses on the toxic and nutritional effects of nZnO at both cellular and physiological levels, as well as the corresponding molecular mechanisms involved. Understanding the cellular transport and dissolution characteristics of nZnO is essential to elucidate its potential toxicity mechanisms. Excess nZnO is absorbed into tissues and accumulates in cells, ultimately resulting in physiological inhibition, nutritional imbalances, and oxidative stress. Conversely, an appropriate amount of nZnO may enhance homeostasis at the organ level, induce moderate production of reactive oxygen species (ROS), and activate changes in antioxidant genes and KEGG pathways, thereby improving the anti-stress capacity of organisms. We also examine the fate of nZnO in marine fishes at the physiological and molecular levels. The effects of nZnO exposure are complex, exhibiting both potential mitigation and toxicity. While excessive use of nZnO poses ecological risks, a judiciously designed application of nZnO holds promise for various fields, including marine fish farming. The regulatory role of nZnO in fish organs, such as viscera and liver, provides new insights into the mechanisms underlying its benefits at the individual level, informing strategies to minimize risks while maximizing benefits.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"9 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599956","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 physical structures of Ni/Fe-NPs with Ni loading ranged from 0.5wt% to 20wt% and the structure dependent reactivity variation towards to trichloroethene (TCE) and carbon tetrachloride (CT) have been fully investigated. A Ni-accumulated surface can be observed for the Ni/Fe-NPs with high Ni loading (20 wt.%), and the structure of other Ni/Fe NPs were identified as a Ni/Fe alloy-like structure with 5wt% Ni/Fe NPs owning the highest surface area and Fe0 content. While the best CT dechlorination rate was 2.5-fold of B-nZVI at 5wt% Ni loading, the best TCE reduction was 12-fold of B-nZVI at medium Ni loading (3wt%-5wt%). Since the primary TCE degradation mechanism is via atomic hydrogen (H*) whereas degradation of CT proceeds via direct electron transfer, the more efficient reduction mechanism for the Ni/Fe NP system was preferably H* reduction. The reduction-rate and the by-products yield variation between medium loading((3wt%-5wt%) and low/high (0.5wt%,20wt%) loading was more significant for TCE than CT. It has been found that Medium Ni loading (3wt%- 5wt%) obviously boosted the β-elimination of TCE to VC due to good storage of H* in Ni catalyst. The production of H* and enhanced electron migration rate were well demonstrated by CV curve and Tafel curve, respectively. The occurrence location of direct electron transfer and H* catalyst in bimetallic Ni/Fe system was further discussed.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"24 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599952","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 EO process with β−PbO2 electrode and Na2SO4 electrolyte could completely remove tetracycline (TC) and achieve an impressive kinetic rate constant of 0.239 min−1. Quantum chemical calculations confirmed that hydrogen bonding was the primary binding force between TC and Na2SO4.

Most studies have focused on the effects of individual NP size on environmental risks and the uptake, translocation, and biological progress of NPs in plants. However, there is a lack of research on the effects of NPs of different sizes and their interactions with the nanoscale layers of plant leaves (hereafter, nanosheets), which may affect adhesion ability, anti-leaching properties, release rate, and fertilizer efficiency. In this study, various sizes (10, 20, 50, 100 nm, and 10 μm) of Fe<small>₃</small>O<small>₄</small>-NPs (Fe<small>₃</small>O<small>₄</small>-NPs) were applied to peanut (Fe strategy I, dicotyledon) and maize (Fe strategy II, monocotyledon) leaves to quantitatively compare their fertilization efficiency and anti-leaching effects. The optimal size for different crop leaves differed due to the distinct microstructures of the nanosheets on the leaf surface. In peanut, the optimal size was 50 nm, resulting in superior dry weight (1.32 g per plant), leaf iron concentration (483 μg g<small>⁻¹</small> DW), and adhesion amount (0.039 mg per plant). For maize, the optimal size was found to be 100 nm, leading to increased dry weight (1.98 g per plant), leaf iron concentration (258 μg g<small>⁻¹</small> DW), and adhesion amount (0.061 mg per plant). A model was developed to simulate the force and work exerted by Fe<small>₃</small>O<small>₄</small>-NPs of different sizes on leaf nanosheets, resulting in the optimal size consistent with the experimental findings. These findings will guide the selection of the optimized NP size for different leaves, thereby enhancing the efficiency of nano-fertilizer utilization and facilitating the development of new types of nano-fertilizers.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"17 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594378","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}

However, a comprehensive risk assessment of NPs is currently constrained by the paucity of knowledge on the chemical reactivity of NPs, which were previously thought to be chemically inert. This review identifies the chemical reactivity of NPs that have undergone abiotic and biotic weathering, including the formation of free radicals, the increase in the content of oxygen-containing functional groups, and the release of plastic leachates. Their interaction with legacy contaminants, such as heavy metals (HMs), is then examined, highlighting their critical role in the oxidation and reduction of HMs, through free radical-mediated redox processes and electron shuttling by carbonyl groups. This review offers new insights into the risk of NPs, where their interaction with legacy contaminants determines the long-term exposure scenario for ecosystems. The unexpectedly large pool of reactive NPs in nature will not only affect their risks but also impact the biogeochemistry of HMs and other contaminants that could react with free radicals and carbonyl groups.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"44 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142589202","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}

Synthesized photocatalysts were thoroughly characterized and their performance was evaluated through the visible light driven photocatalytic degradation of both Microcystis aeruginosa (prokaryotic) and Scenedesmus acuminatus (eukaryotic) algal cells sourced directly from ponds. Exceptional photocatalytic efficiency of CBG evidenced through the variation in chlorophyll-a content, malondialdehyde, and electrolytic leakage confirmed the complete rupture of the algal cells after 3 h of light exposure. This was further reconfirmed through fluorescent microscopy analysis and interestingly, both HABs failed to re-grow even after 10 days. Enhanced performance of CBG was attributed to the boosted generation of charge carriers facilitated by its extended visible light absorption, which in-turn produced reactive oxygen species (<small>^•</small>O<small>₂</small><small>^-</small> and <small>^•</small>OH radicals) that caused irreparable oxidative damage to algal cells, while effectively suppressing the exciton pair recombination supported by its double Z-scheme heterojunction. Furthermore, magnetic recyclability feature of CBG facilitated their easy removal from treated water for avoiding secondary pollution. Design of magnetically recyclable photocatalysts for degrading both prokaryotic and eukaryotic HABs demonstrated here is anticipated to inspire the development of efficient photocatalysts and design cost-effective solutions required for treating ponds and lakes infected with HABs.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"18 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142580705","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}

Weed control of Amaranthus retroflexus by the nanoformulations was also evaluated as a measurement of target delivery. Soybean plants did not show any differences in photosynthetic parameters and a slight oxidative stress with nanoherbicide treatment, with biomass reduction occurred at 60 days after application. The root accumulated metribuzin formulations and translocated to the aerial part for both plant species. The polymeric nanomaterials in the soil mitigated alterations in the bacterial community. Metribuzin formulations, mainly nanoformulations even at low dose (48 g a.i. ha-1<small></small>) caused severe photosynthetic damage in the weed species, with reduction of chlorophyll content (up to 2.35 time) and electron flow (up to 9.22 times), leading to eventual mortality. MTZ nanoformulations presented a greater efficacy (even in 10-fold less dose) for weed control compared to conventional formulation. These findings suggest that MTZ nanoformulations improve weed control and attenuate the negative effects on crop and soil health, offering an important nano-enabled strategy for sustainable weed management.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"97 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594380","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}
