This study presents a novel green approach for the preparation of zeolite material from fly ash using a combination of mechanochemical methods. The physicochemical properties of the synthesized zeolite, including crystal structure and porosity, were systematically investigated. The synthesized zeolite was employed for the adsorption of ammonia nitrogen from aqueous solutions, and their adsorption kinetics and thermodynamics were comprehensively studied. The results revealed that the adsorption of ammonia nitrogen onto the zeolite follows the Langmuir adsorption model. Additionally, the zeolite exhibited strong selective adsorption and remarkable resistance to interference from coexisting cations in the aqueous solution. Finally, regeneration experiments were conducted using NaCl, NaClO, and their mixtures to desorb ammonia nitrogen from the spent zeolite. A total of 17 regeneration cycles were performed until the adsorption capacity of the zeolites was exhausted. The adsorption performance of the regenerated zeolite was evaluated to assess the impact of different reagents and regeneration cycles on adsorption efficiency. The optimal regeneration method was identified, leading to the successful valorization of fly ash into zeolite for ammonia adsorption and the development of effective regeneration strategies for spent zeolite. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

Experimental Study of Erosion of Defective Pipeline under Variable Water Level

SPE Journal 2025年第4期30卷 1956-1969页

作者： Guo, Jixiang Zhang, Yanjun Cheng, Yuxiang Shi, Haoxin Zhang, Xin Zheng, Jianqiao College of Construction Engineering Jilin University China Key Laboratory of Groundwater Resources and Environment Ministry of Education Jilin University China Engineering Research Center of Geothermal Resources Development Technology and Equipment Ministry of Education Jilin University China

Driven by groundwater, defective pipelines can cause soil erosion and pose significant risks to the surrounding infrastructure. In this study, the evolution and collapse characteristics of formation stress caused by defective pipelines were considered not only under the constant groundwater level condition that previous studies have focused on but also under rainfall or flood scenarios (the groundwater level rises briefly and then quickly returns to its original height). This study developed a large-scale 3×2×2 m 3D physical model experimental setup to simulate the process of seepage erosion and collapse within the strata induced by groundwater. The results showed that groundwater seepage provided power for the migration of soil in the stratum, and the defects of pipelines offered migration space for the soil. When soil migration induced by groundwater into the defective pipeline caused the overlying strata to lose bearing capacity, surface subsidence occurred. Compared with the condition of constant groundwater level, the collapse volume under variable groundwater level decreased by 3.48%, but more irregular sinkholes appeared on the surface, which posed a greater threat to regional infrastructure and human activities. The increase in the height of the constant groundwater level not only prolonged the erosion process but also induced a larger erosion cavity and expanded the collapse volume. The increase in overburden thickness intensified the stress change in the stratum, resulting in a larger reduction in in-situ stress and enlarging the scale of erosion and collapse. This study uncovers the critical mechanisms by which rainfall and flooding trigger surface collapse around defective pipelines, offering valuable insights for pipeline design, maintenance, and risk assessment in the petroleum industry.

Micromachined High Gain Diagonal Horn Array Antenna With Suppressed Grating Lobes for 190 GHz-250 GHz

引用

IEEE Transactions on Terahertz Science and technology 2025年第3期15卷 464-472页

作者： Zhao, Yun Zhang, Shao-Min Ye, Fan Li, Sheng Yang, Shi-Cheng Wang, Cai-Xia Ding, Jiang-Qiao Nanjing University of Information Science and Technology School of Electronic and Information Engineering Jiangsu Collaborative Innovation Center of Atmospheric Environment and Equipment Technology Nanjing210044 China China Academy of Space Technology National Key Laboratory of Science and Technology on Space Microwave Xi'an710100 China

This article presents a high gain, broadband silicon micromachined diagonal horn array antenna for the 190 to 250 GHz frequency band. The antenna array is configured to be built from 34 silicon layers. The upper 25 layers of silicon wafers create an 8 × 8 diagonal horn array antenna and the lower 9 layers form the feed network. The diagonal horn is selected as a radiation element for its 45° polarization direction, which suppresses side and grating lobes in the E-plane and H-plane after array formation. Polarization converters are innovatively employed in the feed network to resolve the issue of opposite polarization from waveguide T-junctions. In order to meet the silicon micromachining criteria, all diagonal horns and the feed network are step-profiled designed based on silicon wafer thickness. The 34 silicon layers are aligned and fixed by computer numerical control-milling metal tooling. Monte Carlo analysis is utilized to quantify the interlayer offset errors introduced during the assembly of the wafers. The measurement results are within the error allowance. The antenna achieves a peak gain of 30.9 dBi and a working frequency bandwidth of 27%. Characterized by highly directive radiation patterns with low side lobe levels in the E-plane and H-plane, the antenna is well-suited for next-generation THz point-to-point communication systems. © 2011-2012 IEEE.
