| 2 | Droplet Manipulation and Crystallization Regulation in Inkjet-Printed Perovskite Film Formation显示文摘Emerging organic–inorganic metal halide perovskite materials have become the focus of the optoelectronics research community owing to their excellent photoelectric properties.Nevertheless,challenges still exist for transferring the lab-made devices to largearea industrial modules.Inkjet printing(IJP)technology provides a promising way to fill the gap because of its precise droplet control and uniform large-scale deposition functions.Hence,an in-depth understanding of inkjet-printed perovskite films in terms of droplet manipulation and crystallization regulation is critical for upscaling the perovskite devices to commercial usage.In this review,we give an overview of inkjet-printed high-quality perovskite films and provide guidelines on inkjet-printing large-scale highperformance perovskite devices.First,we analyze theories of droplet formation and perovskite nucleation/crystallization dynamics and then focus on summarizing the perovskite film-formation strategies via IJP,in the aspects of ink engineering,the printing process,and posttreatment.Furthermore,we review the recent advances of inkjet-printed perovskite films on optoelectronic devices,such as perovskite solar cells,perovskite light-emitting diodes,and perovskite photodetectors.Finally,we highlight the“Trilogy Strategies,”including ink engineering,printing process,and posttreatment for printing high-quality perovskite films. | Yajie Cheng Hangjuan Wu Junjie Ma Pengwei Li Zhenkun Gu Shuangquan Zang Liyuan Han Yiqiang Zhang Yanlin Song | 2022 | CCS Chemistry2022，4，5： | 1 |
| 3 | Legionella pneumophila temporally regulates the activity of ADP/ATP translocases by reversible ADP-ribosylation显示文摘The mitochondrion is an important signaling hub that governs diverse cellular functions,including metabolism,energy production,and immunity.Among the hundreds of effectors translocated into host cells by the Dot/Icm system of Legionella pneumophila,several are targeted to mitochondria but the function of most of them remains elusive.Our recent study found that the effector Ceg3 inhibits the activity of ADP/ATP translocases(ANTs)by ADP-ribosylation(ADPR).Here,we show that the effect of Ceg3 is antagonized by Larg1,an effector encoded by lpg0081,a gene that is situated next to ceg3.Larg1 functions to reverse Ceg3-mediated ADPR of ANTs by cleaving the N-glycosidic bond between the ADPR moiety and the modified arginine residues in ANTs,leading to restoration of their activity in ADP/ATP exchange.Structural analysis of Larg1 and its complex with ADPR reveals that this ADPR glycohydrolase harbors a unique macrodomain that catalyzes the removal of ADPR modification on ANTs.Our results also demonstrate that together with Ceg3,Larg1 imposes temporal regulation of the activity of ANTs by reversible ADPR during L.pneumophila infection. | Jiaqi Fu Pengwei Li Hongxin Guan Dan Huang Lei Song Songying Ouyang Zhao-Qing Luo | 2022 | mLife2022，1，1： | 1 |
| 4 | Multifunctional Perovskite Photodetectors: From Molecular-Scale Crystal Structure Design to Micro/Nano-scale Morphology Manipulation显示文摘Multifunctional photodetectors boost the development of traditional optical communication technology and emerging artificial intelligence fields, such as robotics and autonomous driving. However, the current implementation of multifunctional detectors is based on the physical combination of optical lenses, gratings, and multiple photodetectors, the large size and its complex structure hinder the miniaturization, lightweight, and integration of devices. In contrast, perovskite materials have achieved remarkable progress in the field of multifunctional photodetectors due to their diverse crystal structures, simple morphology manipulation, and excellent optoelectronic properties. In this review, we first overview the crystal structures and morphology manipulation techniques of perovskite materials and then summarize the working mechanism and performance parameters of multifunctional photodetectors. Furthermore, the fabrication strategies of multifunctional perovskite photodetectors and their advancements are highlighted, including polarized light detection, spectral detection, angle-sensing detection, and selfpowered detection. Finally, the existing problems of multifunctional detectors and the perspectives of their future development are presented. | Yingjie Zhao Xing Yin Pengwei Li Ziqiu Ren Zhenkun Gu Yiqiang Zhang Yanlin Song | 2023 | Nano-Micro Letters2023，15，10： | 0 |
| 5 | Enhancement of electrical conductivity and electromagnetic interference shielding performance via supercritical CO_(2) induced phase coarsening for double percolated polymer blends显示文摘The electrical conductivity of conductive polymer composites(CPCs)with a classical double percolated structure is highly connected to the phase morphology.However,lots of conductive fillers,which are added to guarantee CPCs’electrical conductivity,caused increased viscosity and limited phase coarsening in traditional atmosphere annealing.Herein,a novel processing method of supercritical carbon dioxide(scCO_(2)),assisted phase coarsening for polylactide acid(PLA)/polystyrene(PS)/multi-wall carbon nanotube(MWCNT)composites was explored.It was first proved that obviously coarsened conductive network of double percolation after scCO_(2) annealing was achieved,which benefited from CO_(2) plasticized polymer chains and thus decreased viscosity.Therefore,the electrical properties and electromagnetic interference(EMI)shielding performance of the composites were significantly improved.The percolation threshold of PLA/PS/MWCNT composites decreased from 0.31 wt.%to 0.16 wt.%,and EMI shielding effectiveness increased from 32.8 to 37.4 dB at 5 wt.%MWCNT loading.This work provides a simple,green,and effective way of post-processing to tailor the phase structure via varying conditions of annealing medium such as temperature,CO_(2) pressure,and time,and gains CPCs with improved electrical conductivity and EMI shielding performance. | Fangfang Zou Xia Liao Pengwei Song Shaozhe Shi Jia Chen Xiaohan Wang Guangxian Li | 2023 | Nano Research2023，16，1： | 0 |
