提出一种基于相干光处理的微波信道化接收机,采用自由谱范围（FSR）不同的两套光频率梳（OFC,optical frequency combs）分别作为光载波和光本振,使得各个信道的输出具有相同的中频。本文方法将微波信号调制到载波OFC的每一个频率分量上,并用法布里-珀罗（F-P）光滤波器对多个信道的调制光边带同时进行带通滤波,然后与本振OFC进行相干探测实现频率下转换。若载波OFC比本振OFC的FSR大于1个信道带宽,并使F-P滤波器的FSR与本振OFC相等,可得到等带宽、等中频的微波信道,降低了后续电路的复杂度。对两个相邻信道进行了实验,将9.74-9.86GHz和9.86-9.98GHz波段的信号分别下转换到两个带宽为120MHz的中频信道,两个中频信道的中心频率仅相差4 MHz分别为900 MHz和896 MHz,表明本文方法能够实现等中频的信道输出。

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.

The formation of C–C bonds is a crucial aspect of organic synthesis. Synthesists' long-term objective is to identify novel catalysts to optimize reaction systems based on traditional transition metal catalysis. This study explores the synthesis and catalytic potential of palladium-installed covalent metal-organic frameworks(CMOFs) based on copper cyclic trinuclear units(Cu-CTUs). By incorporating palladium ions into the imine-based framework JNM-7 through a straightforward immersion method, we achieved a notable enhancement in catalytic activity for critical C–C coupling reactions, including C–H arylation and Sonogashira cross-coupling. The resulting JNM-7-Pd demonstrated remarkable stability and recyclability, maintaining its efficiency over at least three cycles without any decline in efficiency.
