摘要：从1950年10月25日至1958年10月26日,中国人民志愿军在朝鲜直接作战近3年、留驻5年,表明了彼时国际秩序的不稳定。相对于抗日战争反侵略、反殖民、反压迫的被动属性,朝鲜战争无疑更具主动性。中国人民通过战争表现出的决心、勇气,以及取得的最后胜利。

摘要：Two-dimensional conductive metal-organic frameworks (2D c-MOFs) with high flexibility in structure design and functionalization have inspired numerous research interests as promising multifunctional materials due to their porous structure, high conductivity, and rich redox active sites. This review offers a concise overview of 2D c-MOF syntheses and their applications in rechargeable batteries. The electron transport mechanism of 2D c-MOFs will be briefly introduced first. Then we discuss the designs and syntheses of 2D c-MOFs, emphasizing the conjugate structure for high conductivity and the redox activity for efficient energy storage. The electrochemical behaviors of the 2D c-MOFs in different rechargeable battery systems are summarized with attention to their structure-performance correlations and storage mechanism. Particular attention is paid to the significant applied potential of 2D c-MOFs in the Na-ion batteries (NIBs) and K-ion batteries (KIBs), which are more sustainable battery chemistries but are plagued by the dissatisfactory battery performances due to the large size of the Na+ and K+. The challenges and opportunities regarding their efficient synthesis and rechargeable battery applications are also discussed. We expect this review will spark new endeavors to promote the further development of 2D c-MOFs for advanced rechargeable batteries.

摘要：【目的】在高速率无源光网络(PON)需求的快速增长下,低成本低噪声突发模式跨阻放大器(BM-TIA)成为其关键的制约因素。文章基于低成本40 nm互补金属氧化物半导体(CMOS)工艺,设计了一种适用于10吉比特对称无源光网络(XGS-PON)的快速建立低噪声BM-TIA,其可兼容12.5、10.0和2.5 Gbit/s 3种信号速率。【方法】为突破CMOS工艺的带宽和噪声瓶颈,TIA通过多级放大、输入电感均衡网络及提高电源电压的方法实现了要求的低噪声。采用前向放大器与反馈电阻共同调节的增益调节方式,实现了3档位的增益变化和速率变化。针对突发模式信号采用快速直流(DC)消除环路(AOC)来精准消除雪崩击穿二极管(APD)输入的DC电流,运用电荷分享技术加速失调消除环路的建立,并通过转换AOC环路时间常数的方法来抑制基线漂移。【结果】芯片采用40 nm CMOS工艺设计制造,裸片尺寸为945μm×945μm。芯片搭配商用10 Gbit/s APD进行同轴罐(TO-CAN)封装测试。测试结果表明,在12.5、10.0以及2.5 Gbit/s速率下,芯片的灵敏度分别为-29.7,-33.0和-37.6 dBm。在不同速率下,饱和输入光电流均可达2.5 mA,实现了24.7、28.2和32.8 dB的大输入动态范围。芯片的静态功耗为82.5 mW,在整个输入光功率范围内,突发模式下AOC的建立时间均小于23 ns。【结论】将文章所提芯片应用于XGS-PON,不但为基于CMOS工艺的低成本低噪声BM-TIA设计提供了借鉴,也对更高速率PON场景下的芯片设计具有指导意义。

摘要：为快速鉴别检测H3、N2和N8亚型禽流感病毒(Avian influenza virus,AIV),建立了一种可同时检测H3、N2、N8亚型AIV的三重RT-LAMP(triplex reverse transcript loop-mediated isothermal amplification,tRT-LAMP)方法。根据NCBI中H3、N2和N8亚型AIV的NA基因保守序列分别设计3套LAMP引物,同时还设计了与FIP的F1c反向互补的荧光探针(FD),并通过退火的方式将FD结合到标记淬灭基团的FIP(FIP)上,形成FIP-FD复合探针后的荧光被淬灭,当FD与FIP分离后,可检测到荧光信号。通过优化反应温度、特异性、敏感性、干扰性和临床样品检测等成功建立了同时检测H3、N2、N8亚型AIV的tRT-LAMP方法。该方法只需要67℃恒温条件就能准确检测和鉴别AIV的3种不同目的基因,且检测其他相关的禽类病原时不产生非特异性扩增;每反应管检测H3、N2和N8亚型AIV最低限度分别为756、735、790 copies/μL,不同浓度模板之间互不干扰;临床样品检测结果显示,tRT-LAMP结果与RT-qPCR及测序结果完全一致。结果表明该方法具有快速、经济、灵敏和特异的优点,扩增结果还可直接肉眼观察,可应用于临床同时检测H3、N2和N8亚型禽流感病毒。
