Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide. However, unlikethat in female infertility, the role of CT infection in male infertility remains controversial. The objective of this retrospective studywas to explore the impacts of CT infection in the genital tract on sperm quality, sperm acrosin activity, antisperm antibody levels,and inflammation in a large cohort of infertile males in China. A total of 7154 semen samples were collected from infertile malesubjects, 416 of whom were CT positive (CT+ group) and 6738 of whom were CT negative (CT− group), in our hospital betweenJanuary 2016 and December 2018. Routine semen parameters (semen volume, pH, sperm concentration, viability, motility,morphology, etc.), granulocyte elastase levels, antisperm antibody levels, and sperm acrosin activity were compared between theCT+ and CT− groups. Our results showed that CT infection was significantly correlated with an abnormally low semen volume, aswell as an increased white blood cell count and granulocyte elastase level (all P < 0.05) in the semen of infertile males;otherroutine semen parameters were not negatively impacted. The antisperm antibody level and sperm acrosin activity were not affectedby CT infection. These findings suggested that CT infection might contribute to inflammation and hypospermia but does not impairsperm viability, motility morphology, and acrosin activity or generate antisperm antibodies in the infertile males of China.

Non-fullerene acceptor(NFA) based organic solar cells(OSCs) are of high efficiency and low energy loss and low recombination features, which is owing to the advantage of non-fullerene acceptors. The photophysics investigation of non-fullerene solar cells, in comparing to fullerene based analogue as well as mixed acceptor ternary blends could help to understand the working mechanism of NFA functioning mechanism. We choose PBDB-T donor, the fullerene derivative PC71 BM acceptor, and the non-fullerene acceptor ITIC as the model system, to construct binary and ternary solar cells, which then subject to ultrafast spectroscopy investigation. The charge transfer pathway in binary and ternary blends is *** it is seen that ITIC leads to a faster exciton separation and exciton diffusion. ITIC in blends suppresses the geminate recombination and shows smaller amount of charge transfer states, which is beneficial for the device performance. And the addition of ITIC enhances the crystallinity for both donor and acceptor leads to a morphology change of forming bicontinuous crystalline networks and phase separation. In a consequence, fill factor and JSC, increase dramatically for the related OSC.

中点电位平衡问题始终是中点钳位型(NPC)三电平逆变器研究的热点问题。文中首先介绍了NPC逆变器的拓扑结构,并分析了传统虚拟空间矢量调制的工作原理及不足之处。在此基础上,为提高中点电位平衡效果,提出一种改进的变虚拟空间矢量调制方法。该方法首先通过引入变虚拟中矢量平衡因子来重新定义虚拟中矢量,然后分析其在单位开关周期内所能产生的电荷量并据此确立矢量顺序,从而在保持中点电位稳态精度的基础上,提高其动态平衡速度。此外,在确立矢量顺序的过程中,分析了系统的输出状态并引入相占空比法进行优化,以减小系统在动态平衡过程中的输出状态切换次数。仿真和实验结果验证了所提调制算法的有效性。

将PC_(71)BM引入J51∶N2200和PM6∶Y6两个典型的有机光伏系统中,研究了共混相的性质.研究结果表明,共混相中的激子离解和载流子传输过程是影响器件光电转换效率的关键.在J51∶N2200∶PC_(71)BM共混薄膜中,PC_(71)BM在共混相内的聚集会引入能量势垒抑制空穴转移过程.同时,双纤维网络之间间隙的扩大限制了解离后的电子和空穴在共混区内的有效扩散,从而导致较为严重的复合和能量损失.而在PM6∶Y6∶PC_(71)BM共混薄膜中,引入的PC_(71)BM分子均匀分布在共混相中,并能与PM6和Y6分子较好地混合.同时,PC_(71)BM的加入不会干扰Y6到PM6的空穴转移,并增强了共混相的双极性传输特性.这种形貌非常有优势,其中存在大量的给受体界面,且产生的电子和空穴可以迅速扩散,并在晶相中高速传输至电极.该结果揭示了在多尺度形貌调控中共混相结构的重要性,是下一阶段有机太阳能电池效率超过20%需要重点考虑的问题.
