17-Estradiol (E2) is a natural steroidal estrogen essential for a variety of physiological functions in organisms. However, external E2, which is renowned for its potent biological effects, is also considered to be an endocrine-disrupting compound (EDC) capable of disturbing the normal operation of the endocrine system, even at nanogram-per-liter (ng/L) concentrations. Studies have revealed that medical and livestock wastewater can be contaminated with E2, which poses potential risks to human health. Currently, the primary method for detecting E2 relies on liquid chromatography-mass spectrometry, which is limited with regard to on-site or large-scale sample testing due to instrumental constraints. Herein, we developed a magnetic graphene oxide (MGO)/aptamer separating material. The MGO was synthesized by creating a water-in-oil microemulsion at 90 ℃, an agarose hydrogel to load the FeO nanoparticles, and layered graphene oxide (GO). In contrast to conventional methods, such as chemical co-precipitation and solvothermal approaches, this method is more time-efficient and does not require high temperature or pressure. Moreover, the use of a physical encapsulation technique for enwrapping the FeO nanoparticles and layered GO eliminates the need for chemical modification. This approach reduces the use of harmful chemicals, ensures complete loading, and results in highly efficient encapsulation. The MGO was characterized using Fourier-transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM), as well as dynamic light scattering (DLS) and Zeta potential analyses, which revealed that the FeO nanoparticles had been successfully loaded onto the GO to produce MGO particles mainly around 5 μm in size. Additionally, this study demonstrated that the aqueous MGO dispersion is highly stable. This substance was used to develop a fluorescent biosensor that uses a "turn-on" mechanism to rapidly and highly sensitively detect E2. MGO is capable of adsorbing a fl

Broadband and perfect terahertz absorber based on multilayer metamaterial with cross-ring patterned structures

引用

Optoelectronics Letters 2025年第1期21卷 1-6页

作者： WEN Jin LIU Zhanzhi WU zhengwei PAN yu ZHANG Ying School of Science Xi'an Shiyou University Shaanxi Key Laboratory of Measurement and Control Technology for Oil and Gas Wells

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.

Chinese Physics B 2021年第6期30卷 106-110页

作者： xin-Feng Jin Li-zhen Jiang Xiao-yu Chen College of Information and Electronic Engineering Zhejiang Gongshang UniversityHangzhou 310018China

We use the generalized Wootters formula, the positive partial transpose(PPT) criterion and the matched entanglement witness, to detect entanglement of three-qubit GHZ and W superposition state and its decayed states. It shows that the results of the generalized Wootters formula in the part near the W state are tight. In the other parts, the PPT criterion is superior to the generalized Wootters formula. Furthermore, we investigate the relationship between entanglement and coherence.

输尿管内窥镜手术是目前针对肾结石的主流治疗方案,其外形细长、镜体柔软,能够灵活穿越人体自然腔道的内径狭窄的尿道和输尿管,检查视野范围更广,使医生能够更好地观察到病变区域.但一般的输尿管内窥镜仅配备单目摄像头进行配合手术操作,无法借助额外设备获取数据导致了其图像信息的匮乏;同时,相比于胃肠、鼻镜等手术场景,本研究的肾内场景在不具备公开数据集的同时,图像质量参差不齐,表面纹理细节不足,孔洞区域褶皱少,受模糊反光等干扰大,都易使深度估计受到影响针对以上问题,提出了一种基于改进风格迁移模型的深度估计方法.该方法首先根据术前CT图像重建肾脏内部腔道模型并提取中心路径,将虚拟内窥镜的摄像头设置在插值后的路径点上,构建了虚拟内窥镜漫游图像与深度估计图像一一对应的数据集,并基于此数据集训练了一个深度估计模型;随后,使用添加高效通道注意力(ECA)模块的改进风格迁移模型,将真实内窥镜图像域迁移至虚拟内窥镜图像域;最后,再将经由风格迁移产生的虚拟内窥镜图像送入上述训练得来的深度估计模型中,最终实现真实内窥镜图像的深度估计.所提方法的可行性及有效性在输尿管钬激光碎石术的图像中得到验证.

Chinese Journal of Chemical Engineering 2022年第4期35卷 369-376页

作者： zhen He yu Zhou yuxin Wang Pingyi Guo Wensen Jiang Caizhen Yao xin Shu School of Materials Science and Engineering Jiangsu University of Science and TechnologyZhenjiang 212100China Cedars-Sinai Medical Center Los AngelesCAUSA Laser Fusion Research Center China Academy of Engineering PhysicsMianyang 621900China Hunan Aerospace TianLu Advanced Materials Testing Co.Ltd Changsha 410299China

Several Ni-W-P-TiO_(2) nanocomposite coatings were developed by the sol-enhanced electroplating method. The phase and elemental compositions of coatings were determined, and the surface and cross-section morphology were characterized. The mechanical and corrosion performance were systematically tested. The results revealed the addition of 5 ml·L^(-1) TiO_(2) sol caused a compact coating surface,while higher concentrations of TiO_(2) reduced the coating thickness and led to the inferior surface microstructure. The comparison in physiochemical properties of prepared coatings confirmed the superior performance of the Ni-W-P-TiO_(2) nanocomposite coating at 5 ml·L^(-1) TiO_(2) sol addition. Under this condition, the best mechanical properties were achieved when abrasive wear was the dominating wearresistance mechanism, and the best corrosion resistance was obtained due to its smooth and compact surface microstructure.

The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.
