Chemical Engineering Research and Design 2025年 218卷 421-427页

作者： Shao, Qi Xiao, Haoran Gao, Lei Chen, Huiming Long, Chao State Key Laboratory of Pollution Control and Resource Reuse School of the Environment Nanjing University 163 Xianlin Avenue Nanjing210023 China Nanjing University & Yancheng Academy of Environmental Protection Technology and Engineering Yancheng224000 China

As a VOCs elimination method at low temperature, ozone catalytic oxidation technology has received extensive attention recently. However, there is still lack of reports on the pilot-scale application of this technology. Herein, a pilot-scale catalyst (Mn/Y) was prepared by loading MnOx on the commercial Y zeolite using a simple impregnation method, which exhibited effective removal effect of TVOCs in the actual VOCs exhaust gas from a shoe factory. Although Mn/Y was inevitably deactivated during the long-term reaction, the catalytic activity of the catalyst can be restored after in-situ heating in the ozone flow. Through the investigation of the physical and chemical structural properties of the fresh catalyst, deactivated catalyst and regenerated catalysts, it was found that the disappearance of some easily reducible MnOx and ozone decomposition site, as well as the accumulation of some by-products were the reason for the deactivation of the catalyst. This work can provide some theoretical guidance for the ozone catalytic oxidation of VOCs from a pilot-scale view. © 2025 Institution of Chemical Engineers

Structural health monitoring (SHM) of hydraulic pipelines plays a crucial role in preventing catastrophic failures, particularly when measuring large strains with high sensitivity. This study presents a novel high-sensitivity strain sensor utilizing femtosecond fiber Bragg grating (FS-FBG) technology to overcome the limitations of conventional monitoring techniques in extreme conditions. The sensor incorporates two key components: sensing and measuring members, featuring an innovative skeletonized sensitized shaft design. A pre-stressed FS-FBG is suspended axially within the structure. The relationship between fiber Bragg grating (FBG) wavelength displacement and pipe surface strain was validated using Bernoulli-Euler beam theory and finite element analysis. In order to accurately calibrate the performance of the sensor, a precision pipe deformation device was designed. Experimental results demonstrate that the sensor achieves a sensitivity of 4.19 pm/ μϵ, which is 3.4 times higher than that of the FBG sensor, in the range of 0-1650 μϵ of the pipe surface microstrain, and at the same time, it has excellent linearity, creep-resistant performance, and temperature compensation effect. The results provide a reliable solution for large strain monitoring of hydraulic pipelines under severe conditions. © 2001-2012 IEEE.

The solid electrolyte interphase (SEI) is intimately associated with the solvation structure in lithium metal batteries (LMBs), but it is difficult to incorporate the anions into the solvation structure. In this work, bis(trimethylsilyl) sulfate (BTMSS) is introduced as a bifunctional additive to bridge the cation-anion bond to modulate the solvation structure and modify the SEI composition. First, it can simultaneously complex with Li+ and PF6- to form the Li+-BTMSS-PF6- complex, thereby promoting more PF6- to enter the solvation sheath. Moreover, BTMSS has a lower LUMO energy level (−0.58 eV) and thus allows preferential decomposition to generate Li2SO3. The dual function ultimately forms the LiF/Li2SO3-rich SEI. Consequently, the BTMSS-modified electrolyte exhibits stable cycling for more than 600 h in symmetric cells. Furthermore, after 450 cycles at 1 C, the Li//LiFePO4 (7.13 mg cm-2) cell maintains 80% capacity retention. This study presents an effective additive strategy for advancing highly reversible LMBs. © 2025 American Chemical Society.

Transport, transformation, and ecological impacts of brominated flame retardants in soils: A comprehensive review

Environmental Chemistry and Ecotoxicology

引用

Environmental Chemistry and Ecotoxicology 2025年 7卷 1142-1157页

作者： Jia Zhang Dan Li Ying Yuan Kunlong Hui Wenbing Tan State Key Laboratory of Environmental Criteria and Risk Assessment State Environmental Protection Key Laboratory of Simulation and Control of Groundwater Pollution Chinese Research Academy of Environmental Sciences Beijing 100012 China

Brominated flame retardants (BFRs) have become significant contaminants of emerging concern (CECs), resulting in detrimental effects on soil health, human health, and ecosystem sustainability. Their environmental impacts have spurred extensive research into environmental chemistry and ecotoxicology. Despite the widespread detection of both BFRs and Novel Brominated Flame Retardants (NBFRs) in soils, there are few assessments of the environmental behavior and fate of the BFRs. Therefore, this review comprehensively identifies the sources, distribution, transport, transformation, ecotoxicological effects, and remediation strategies of BFRs in soils. Principal findings indicate that adsorption-desorption, mostly influenced by soil organic matter, controls the mobility and transformation of BFRs. Photolysis dominates surface soils, while aerobic and anaerobic biodegradation predominate in subsurface layers. The main factors influencing the bioavailability of BFRs are shed light on in this review. These factors such as the physicochemical properties of BFRs, soil characteristics, and combined pollution are specifically discussed. Moreover, the development, physiological, and biochemical responses of soil organisms to exposure to the BFRs are summarized. Single strategies for addressing BFRs have certain limitations. Urgent actions are needed to focus on environmental behavior and remediation strategies under the “One Health” framework to enrich research gap areas of BFRs, NBFRs, and transformation products.

Analysis of the Influencing Factors of Heavy Metal Pollution in the Surrounding Soil of Typical Industrial Enterprises in Sichuan based on Geographical Detectors

引用

Huanjing Kexue/Environmental Science 2025年第5期46卷 3229-3236页

作者： Sun, Dong-Yue Jiang, Xiao-Xu Zhou, Xiao-Bai Yang, Nan Feng, Xue China National Environmental Monitoring Centre Beijing100012 China State Environmental Protection Key Laboratory of Quality Control in Environmental Monitoring Beijing100012 China

The surrounding soils of nine typical industrial enterprises in Sichuan Province were selected as the research objects. The contents of heavy metals Cd，Hg，As，Pb，Cr，Cu，Ni，and Zn in 25 surface soil samples around industrial enterprises were collected and analyzed. The potential ecological risk assessment method was used to evaluate the potential ecological risks of heavy metals in the soil. Based on the geographic detector，ten influencing factors，such as the distance from the enterprise，the relative elevation difference with the location of the enterprise，and the type of industry were selected as independent variables，and the analysis was conducted with the content of heavy metals as the dependent variable，and further verification was conducted using correlation analysis. The results showed that the soils around industrial enterprises in the study area were mainly characterized by "moderate"potential risks，accounting for 40%，whereas the other four risk types each accounted for 8% to 20%. Cd and Hg were the main contributing indicators to the potential ecological risk in the study area. The results of the geographic detector showed that"distance from the enterprise"had the strongest explanatory power for Cd，Pb，and Zn;"industry type"had the strongest explanatory power for As，Cr，Cu，and Ni;and"precipitation"had the strongest explanatory power for Hg. The results of interaction detection showed that after the interaction of each factor，the explanatory power was increased，indicating that the content of heavy metals in soil was affected by a compound of multiple influencing factors. The results of correlation verification showed that there were significant correlations between Cd，As，Pb，and Zn，indicating a certain homogeneity among the four heavy metals，which was basically consistent with the results of the geographic detector and could further validate the results of the geographic detector，making the results more accurate and reliable. © 2025 Science Press.

Existing research has shown the inconsistency between point forecasting and deterministic optimization, yet the consistency between probabilistic forecast indices and uncertain optimization has not been investigated. This letter fills this gap by undertaking scenario-based tests to reveal the mismatch and proposing a new cost-oriented score (COS) to indicate whether a probabilistic forecast can lead to a "better"decision-making performance in unit commitment and economic dispatch. © 1969-2012 IEEE.
