可拉伸应变传感器在减隔震领域具有广阔的应用前景,然而,研发低成本和高稳定性可拉伸应变传感器仍然是一个巨大挑战。本文采用开炼法制备出多壁碳纳米管(MWCNT)-导电炭黑(CB)/甲基乙烯基硅橡胶(VMQ)导电纳米复合材料。研究MWCNT与CB之间的协同效应对复合材料分散性能、导电性能、力学性能及电阻-应变响应性能影响。结果表明:添加CB后复合材料力学性能提升,具有较低的渗流阈值(1.24wt%),5000次循环加载-卸载过程中表现出优异的电阻-应变响应稳定性。此外,MWCNT-CB/VMQ复合材料相比于MWCNT/VMQ、CB/VMQ复合材料在电阻-应变响应性能中没有出现肩峰现象,同时解释了肩峰现象机制。通过SEM发现复合材料中MWCNT和CB均匀分布及形成的协同效应是低阈值和稳定电阻-应变响应性能的重要原因。通过隧道效应理论模型解释了电阻-应变响应机制。该复合材料对减隔震结构应变监测具有巨大潜力。

提出一种基于分数阶时域Talbot效应的宽带射频信号实时频谱分析方案。该方案基于采样和色散结构,实现射频信号频率到光脉冲时间间隔的映射。通过预先经过一个满足分数阶时域Talbot距离的色散元件,光脉冲在采样之前的重复频率发生倍增。利用分数阶时域Talbot效应,可以显著提升系统的频率测量带宽。实验结果表明,利用9阶分数阶时域Talbot效应,实现29.7 GHz带宽内单音和双音射频信号的实时频谱分析。数值仿真结果进一步验证了该方案能够有效分析频率快速变化的宽带射频信号。该方案结构简单、带宽大、可实时处理,有望应用于电子对抗、宽带雷达、认知无线电等场景。

Super-Resolution Fluorescence Microscopy for Cilia Investigation and Ciliopathy Diagnosis（特邀）

引用

激光与光电子学进展 2024年第6期 270-281页

作者： Liu Zhen Wu yang The Hong Kong University of Science and Technology Division of Life Science

The last two decades have witnessed the invention and development of super-resolution microscopy(SRM) that breaks the diffraction limit of light and pushes the fluorescence microscopy resolution to several nanometers. While SRM is widely used in biological studies, such as resolving subdiffraction structures, molecular mapping, tracking single molecules, probing protein-protein interactions, and observing organelle dynamics, its direct application in translational medicine, such as disease diagnosis, is still preliminary. Despite their small size, cilia play a crucial role as organelles in cell signaling and motility, with defects in cilia leading to ciliopathy. Similar to other miniature organelles and macromolecular complexes, cilia are ideal for super-resolution imaging. In this review, we will 1) introduce cilia and ciliopathy, 2) show how SRM extends our knowledge of cilia, and 3) focus on how SRM improves the diagnosis of motile ciliopathies.
