摘要：
Revegetation is effective in improving soil quality in ecologically fragile areas. However, little is known about the impact of diverse phytomanagement strategies of tailings on soil quality and ecological security in erosion-prone areas. We investigated the water stability, soil aggregate nutrients, and the risk of heavy metal contamination of abandoned tailings under phytomanagement and in adjacent bare land on the Loess Plateau. The results showed that phytomanagement significantly enhanced soil aggregate stability, as demonstrated by higher contents of soil organic carbon (SOC), glomalin-related soil protein (GRSP), aromatic-C, and alkene-C in macro-aggregates. The pollution load index (PLI) and ecological risk index (RI) of soil heavy metals were lower in shrub/herbaceous mixed forests than in natural grasslands and planted forests. The risk of heavy metal contamination was higher in macro-aggregates (>0.25mm) than in micro-aggregates (<0.25mm) and was significantly and positively correlated with the SOC and GRSP contents of the aggregates. Our study demonstrates that soil aggregate quality is closely related to the fate of heavy metals. Diversified tailing revegetation measures can improve soil quality and ensure ecological security.

摘要：
Pesticides are indispensable to maintain crop quality and food production worldwide, but their use also poses environmental risks. Pesticide risk assessment involves a series of complex, expensive and time-consuming toxicity tests. To improve the efficiency and accuracy for assessing the environmental impact of pesticides, numerous computational tools have been developed. However, there is a notable deficiency in critical analysis or a systematic summary of environmental risk assessment tools and their applicable contexts. Here, many of the current approaches and tools for assessing environmental risks posed by pesticides are reviewed, and the question of whether these tools are fit for use on complex multicomponent scenarios is discussed. We analyze the adaptations of these tools to aquatic and terrestrial ecosystems, followed by the provision of resources for predicting pesticide concentrations in environmental medias, including air, soil and water. The successful application of computational tools for risk assessment and interpretation of predicted results will also be discussed. This assessment serves as a valuable resource, enabling scientists to utilize suitable models to enhance the robustness of pesticides risk assessments.

摘要：
Poly(ionic liquid)s (PILs) bearing high ionic densities are promising candidates for carbon dioxide (CO(2)) fixation. However, efficient and metal-free methods for boosting the catalytic efficiencies of PILs are still challenging. In this study, a novel family of poly(ionic liquid)-coated carbon nanotube nanoarchitectures (CNTs@PIL) were facilely prepared via a noncovalent and in-situ polymerization method. The effects of different carbon nanotubes (CNTs) and PILs on the structure, properties, and catalytic performance of the composite catalysts were systematically investigated. Characterizations and experimental results showed that hybridization of PIL with hydroxyl- or carboxyl-functionalized CNTs (CNT-OH, CNT-COOH) endows the composite catalyst with increased porosity, CO(2) capture capacity, swelling ability and diffusion rate with respect to individual PIL, and allows the CNTs@PIL to provide H-bond donors for the synergistic activation of epoxides at the interfacial layer. Benefiting from these merits, the optimal composite catalyst (CNT-OH@PIL) delivered a super catalytic efficiency in the cycloaddition of CO(2) to propylene oxide, which was over 4.5 times that of control PIL under metal- and co-catalyst free conditions. Additionally, CNT-OH@PIL showed high carbon dioxide/nitrogen (CO(2)/N(2)) adsorptive selectivity and could smoothly catalyze the cycloaddition reaction with a simulated flue gas (15% CO(2) and 85% N(2)). Furthermore, the CNT-OH@PIL exhibited broad substrate tolerance and could be readily recycled and efficiently reused at least 12 times. Hybridization of PIL with functionalized CNTs provides a feasible approach for boosting the catalytic performance of PIL-based solid catalysts for CO(2) fixation.

摘要：
Over the past decade, China has experienced a decline in atmospheric reactive nitrogen (Nr) emissions. Given that China's subtropical region is a significant nitrogen (N) deposition hotspot, it is essential to accurately quantify the ten-year variations in dry and wet N depositions in the context of reductions in atmospheric Nr emissions. Here, we evaluated the spatiotemporal variation in N deposition on forest, paddy field and tea field ecosystems in a typical subtropical agricultural catchment from 2011 to 2020. Our findings indicated a significant decrease in total N deposition in both the tea field ecosystem (41.5-30.5kgNha(-1)) and the forest ecosystem (40.8-25.7kgNha(-1)) (P<0.05), but no significant change in the paddy field ecosystem (29.3-32.9kgNha(-1)). Specifically, dry N deposition exhibited significant declines except in the paddy field ecosystem, whereas wet N deposition had no significant change. The reduction in total oxidized and reduced N depositions in forest and tea field ecosystems is attributed to the decrease in NO(x) and NH(3) emissions. Additionally, The ratio of NH(x) deposition to total N deposition all exceeded 0.5 in three ecosystems and the NH(x)/NO(y) ratio had an increasing trend (P<0.05) in the paddy field, indicating that reactive N emissions from agricultural sources were the primary contributor to overall N deposition. Our study emphasizes that despite the decreasing trend in N deposition, it still exceeds the critical loads of natural ecosystems and requires stringent N emissions control, particularly from agricultural sources, in the future.

摘要：
As recently developed two-dimensional (2D) materials, MXenes have attracted great attention in the fields of sensing, catalysis, energy, and electromagnetism due to their good electrical, mechanical, and optical properties and their biocompatibility. Their rich elemental composition, diverse surface functional groups and flexible bandgaps enable them to exhibit ideal physicochemical properties that are superior to those of traditional 2D materials. Therefore, MXenes not only serve as ideal biosensing materials but also show great potential in biomedical-related applications. In this review, we summarize the latest research on MXenes in the fields of biosensing and biomedicine. First, we introduce the different synthe-sis strategies and unique properties of MXenes. Then, according to the sensing mechanism, we divide the biosensing applications of MXenes into three subcategories: electrochemical, photochemical, and opto-electrochemical biosensors. Moreover, we systematically evaluate the biomedical applications of MXenes from four aspects: antibacterial activity, bioimaging, therapeutics and theranostics. How the specific chemical and physical properties of MXenes that can influence the efficiency of biosensing and biomedicine are highlighted, as well as the structure-performance relationships determining detection sensitivity and the toxicity of materials. Finally, we discuss the recent challenges and future prospects and opportunities for MXenes. It is expected that the review could promote the development of related fields.(c) 2022 Elsevier B.V.

摘要：
A bioinspired soft elastic metamaterial with a size equivalent to the current cochlear implant that can be seen as a prototype of passive artificial cochlea with a frequency resolution of 30 Hz is proposed. This work will inspire future work in the fabrication of totally implantable passive artificial cochlea that enables the users to hear naturally. Abstract Natural hearing which means hearing naturally like normal people is critical for patients with hearing loss to participate in life. Cochlear implants have enabled numerous severe hearing loss patients to hear voice functionally, while cochlear implant users can hardly distinguish different tones or appreciate music subject to the absence of rate coding and insufficient frequency channels. Here a bioinspired soft elastic metamaterial that reproduces the shape and key functions of the human cochlea is reported. Inspired by human cochlea, the metamaterials are designed to possess graded microstructures with high effective refractive index distributed on a spiral shape to implement position‐related frequency demultiplexing, passive sound enhancements of 10 times, and high‐speed parallel processing of 168‐channel sound/piezoelectric signals. Besides, it is demonstrated that natural hearing artificial cochlea has fine frequency resolution up to 30 Hz, a wide audible range from 150–12 000 Hz, and a considerable output voltage that can activate the auditory pathway in mice. This work blazes a promising trail for reconstruction of natural hearing in patients with severe hearing loss.
