| 1 | Atomistic Surface Passivation of CH_(3)NH_(3)PbI_(3) Perovskite Single Crystals for Highly Sensitive Coplanar-Structure X-Ray Detectors显示文摘Organic-inorganic halide perovskites(OIHPs)are recognized as the promising next-generation X-ray detection materials.However,the device performance is largely limited by the ion migration issue of OIHPs.Here,we reported a simple atomistic surface passivation strategy with methylammonium iodide(MAI)to remarkably increase the ion migration activation energy of CH_(3)NH_(3)PbI_(3)single crystals.The amount of MAI deposited on the crystal surface is finely regulated by a self-assemble process to effectively suppress the metallic lead defects,while not introducing extra mobile ions,which results in significantly improved dark current stability of the coplanar-structure devices under a large electric field of 100Vmm^(-1).The X-ray detectors hence exhibit a record-high sensitivity above 700,000μC Gy^(-1)_(air) cm^(-2)under continuum X-ray irradiation with energy up to 50 keV,which enables an ultralow X-ray detection limit down to 1.5 nGy_(air)s^(-1).Our findings will allow for the dramatically reduced X-ray exposure of human bodies in medical imaging applications. | Yilong Song Liqi Li Weihui Bi Mingwei Hao Yifei Kang Anran Wang Zisheng Wang Hanming Li Xiaohui Li Yanjun Fang Deren Yang Qingfeng Dong | 2020 | Research2020，，1： | 5 |

| 6 | Selected aptamer specially combing 5-8F cells based on automatic screening instrument显示文摘Since the concept of aptamer emerged,many scientists have launched a rich field of research around it.However,few nucleic acids aptamer which use cell as target can be put into practical applications.We believe that a great deal of this lies in the complexity and irreproducibility of aptamer screening experiments themselves.The complexity is due to the cumbersome processes and the technical requirements for laboratory personnel,whereas irreproducibility arises from the fact that the starting point of such screens is nucleic acid libraries with random fragments,and that different libraries directly determine the differences or even the success or failure of screening results.The complexity and irreproducibility mentioned above,in turn,lead to the inability of this experiment to unfold on a large scale,which naturally cannot lead to excellent results for practical applications.In response to this problem,our group has developed an instrument for automated screening of tumor cell nucleic acid aptamers and characterized the properties of nucleic acid aptamers obtained using this instrument in a comprehensive manner. | Zhukang Guo Baijiang Jin Yile Fang Yan Deng Zhu Chen Hui Chen Song Li Franklin Wang-Ngan Chow Polly H.M.Leung Hanming Wang Lei Cai Nongyue He | 2022 | Chinese Chemical Letters2022，33，9： | 0 |
