1Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
2Flexible high energy density zinc-ion batteries enabled by binder-free MnO_(2)/reduced graphene oxide electrode显示文摘We demonstrate a rechargeable zinc-ion battery with high energy density and cyclability using MnO_(2)and reduced graphene oxide(MnO_(2)/rGO)electrode.The flexible and binder free electrode,with high MnO_(2)mass ratio(80 wt%of MnO_(2)),is fabricated using vacuum filtration without any additional additives other than rGO.Compared to batteries with conventional MnO_(2)electrodes,the Zn-MnO_(2)/rGO battery shows a significant enhanced capacity(332.2 mAh g^(-1)at 0.3 A g^(-1)),improved rate capability(172.3 mAh g^(-1)at 6 A g^(-1))and cyclability.The capacity retention remains 96%after 500 charge/discharge cycles at 6 A g^(-1).The high MnO_(2)mass ratio makes MnO_(2)/rGO electrode advantageous when the capacity is normalized to the whole electrode,particularly at high rates.The calculated gravimetric energy density of Zn-MnO_(2)/rGO battery is 33.17Wh kg^(-1),which is comparable to the existing commercial lead-acid batteries(30-40Wh kg^(-1)).Furthermore,the discharge profile and capacity of our Zn-MnO_(2)/rGO battery shows no deterioration during bending test,indicating good flexibility.As a result,zinc-ion battery is believed to be a promising technology for powering next generation flexible electronics.Yuan Huang Jiuwei Liu Qiyao Huang Zijian Zheng Pritesh Hiralal Fulin Zheng Dilek Ozgit Sikai Su Shuming Chen Ping-Heng Tan Shengdong Zhang Hang Zhou 2018npj Flexible Electronics2018,2,1:4
3Overview to the Hard X-ray Modulation Telescope (Insight-HXMT) Satellite显示文摘As China’s first X-ray astronomical satellite, the Hard X-ray Modulation Telescope (HXMT), which was dubbed as Insight-HXMT after the launch on June 15, 2017, is a wide-band(1-250 ke V) slat-collimator-based X-ray astronomy satellite with the capability of all-sky monitoring in 0.2-3 Me V. It was designed to perform pointing, scanning and gamma-ray burst(GRB)observations and, based on the Direct Demodulation Method (DDM), the image of the scanned sky region can be reconstructed.Here we give an overview of the mission and its progresses, including payload, core sciences, ground calibration/facility, ground segment, data archive, software, in-orbit performance, calibration, background model, observations and some preliminary results.Shuang-Nan Zhang TiPei Li FangJun Lu LiMing Song YuPeng X u CongZhan Liu Yong Chen XueLei Cao QingCui Bu Zhi Chang Gang Chen Li Chen TianXiang Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong Yuan Yuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan Can Gungor ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge Ou JinLu Qu Na Sai RenCheng Shang GuoHong Shen Liang Sun Ying Tan Lian Tao YouLi Tuo Chen Wang ChunQin Wang GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BaiYang Wu BoBing Wu Mei Wu GuangCheng Xiao ShaoLin Xiong LinLi Yan JiaWei Yang Sheng Yang YanJi Yang QiBin Yi Bin Yuan AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang ShenYi Zhangs Shu Zhang Tong Zhang WanChang Zhang Wei Zhang WenZhao Zhang Yi Zhang YiFei Zhang YongJie Zhang Yue Zhang Zhao Zhang Zhi Zhang ZiLiang Zhang HaiSheng Zhao XiaoFan Zhao ShiJie Zheng JianFeng Zhou YuXuan Zhu Yue Zhu RenLin Zhuang 2020Science China(Physics,Mechanics & Astronomy)2020,63,4:2
4Interfacial engineering of printable bottom back metal electrodes for full-solution processed flexible organic solar cells显示文摘Printing of metal bottom back electrodes of flexible organic solar cells(FOSCs) at low temperature is of great significance to realize the full-solution fabrication technology. However, this has been difficult to achieve because often the interfacial properties of those printed electrodes, including conductivity, roughness, work function,optical and mechanical flexibility, cannot meet the device requirement at the same time. In this work, we fabricate printed Ag and Cu bottom back cathodes by a low-temperature solution technique named polymer-assisted metal deposition(PAMD) on flexible PET substrates. Branched polyethylenimine(PEI) and ZnO thin films are used as the interface modification layers(IMLs) of these cathodes. Detailed experimental studies on the electrical, mechanical, and morphological properties, and simulation study on the optical properties of these IMLs are carried out to understand and optimize the interface of printed cathodes. We demonstrate that the highest power conversion efficiency over 3.0% can be achieved from a full-solution processed OFSC with the device structure being PAMDAg/PEI/P3 HT:PC_(61)BM/PH1000. This device also acquires remarkable stability upon repeating bending tests.Hongyu Zhen Kan Li Yaokang Zhang Lina Chen Liyong Niu Xiaoling Wei Xu Fang Peng You Zhike Liu Dongrui Wang Feng Yan Zijian Zheng 2018Journal of Semiconductors2018,39,1:2
5Vacuum-free fabrication of high-performance semitransparent perovskite solar cells via e-glue assisted lamination process显示文摘From a base material of conductive polymer(poly-(3,4-ethylenedioxythiophene):poly(styrenesulfonate),PEDOT:PSS),a flexible and high-conductivity(as low as 45Ω/sq)transparent electrode was fabricated on polydimethylsiloxane elastomer by an acid treatment and transfer process.Combined with the D-sorbitol-doped PEDOT:PSS electric glue,we successfully demonstrated a vacuum-free and ambient lamination fabrication process for semi-transparent perovskite solar cells using triple cation Cs0.05(MA0.17FA0.83)0.95Pb(I0.83Br0.17)3perovskite.By this manufacturing-friendly lamination process,we fabricated semitransparent perovskite solar cell devices with power conversion efficiencies up to 16.4%and variable transparencies.Hengkai Zhang Yaokang Zhang Guang Yang Zhiwei Ren Wei Yu Dong Shen Chun-Shing Lee Zijian Zheng Gang Li 2019Science China Chemistry2019,62,7:2

7Functionalized Fiber-Based Strain Sensors:Pathway to Next-Generation Wearable Electronics显示文摘Wearable strain sensors are arousing increasing research interests in recent years on account of their potentials in motion detection,personal and public healthcare,future entertainment,man-machine interaction,artificial intelligence,and so forth.Much research has focused on fiber-based sensors due to the appealing performance of fibers,including processing flexibility,wearing comfortability,outstanding lifetime and serviceability,low-cost and large-scale capacity.Herein,we review the latest advances in functionalization and device fabrication of fiber materials toward applications in fiber-based wearable strain sensors.We describe the approaches for preparing conductive fibers such as spinning,surface modification,and structural transformation.We also introduce the fabrication and sensing mechanisms of state-of-the-art sensors and analyze their merits and demerits.The applications toward motion detection,healthcare,man-machine interaction,future entertainment,and multifunctional sensing are summarized with typical examples.We finally critically analyze tough challenges and future remarks of fiber-based strain sensors,aiming to implement them in real applications.Zekun Liu Tianxue Zhu Junru Wang Zijian Zheng Yi Li Jiashen Li Yuekun Lai 2022Nano-Micro Letters2022,14,4:2
8HY5-HDA9 orchestrates the transcription of HsfA2 to modulate salt stress response in Arabidopsis显示文摘Integration of light signaling and diverse abiotic stress responses contribute to plant survival in a changing environment.Some reports have indicated that light signals contribute a plant’s ability to deal with heat,cold,and stress.However,the molecular link between light signaling and the saltresponse pathways remains unclear.We demonstrate here that increasing light intensity elevates the salt stress tolerance of plants.Depletion of HY5,a key component of light signaling,causes Arabidopsis thaliana to become salinity sensitive.Interestingly,the small heat shock protein(sHsp)family genes are upregulated in hy5-215 mutant plants,and HsfA 2 is commonly involved in the regulation of these sH sps.We found that HY5directly binds to the G-box motifs in the HsfA2promoter,with the cooperation of HISTONE DEACETYLASE 9(HDA9),to repress its expression.Furthermore,the accumulation of HDA9 and the interaction between HY5 and HDA9 are significantly enhanced by salt stress.On the contrary,high temperature triggers HY5 and HDA9 degradation,which leads to dissociation of HY5-HDA9from the HsfA2 promoter,thereby reducing salt tolerance.Under salt and heat stress conditions,fine tuning of protein accumulation and an interaction between HY5 and HDA9 regulate HsfA2 expression.This implies that HY5,HDA9,and HsfA2play important roles in the integration of light signaling with salt stress and heat shock response.Jiaheng Yang Xiao Qu Tao Li Yixiang Gao Haonan Du Lanjie Zheng Manchun Ji Paifeng Zhang Yan Zhang Jinxin Hu Liangyu Liu Zefu Lu Zijian Yang Huiyong Zhang Jianping Yang Yongqing Jiao Xu Zheng 2023Journal of Integrative Plant Biology2023,65,1:1

11Supramolecular-mediated ball-in-ball porous carbon nanospheres for ultrafast energy storage显示文摘Hierarchical porous carbons are the most viable electrode material for supercapacitors because of their balanced capacitive performance and chemical stability.Their pore connectivity plays a pivotal role in electrolyte transport,which is quantified by a new parameter,defined in this work as the longest possible pore separation(LPPS).Herein,we report hierarchical porous carbon nanospheres(HPC-NS)with a unique ball-in-ball structure,which is achieved by the pyrolysis of a supramolecular complex ofγ-cyclodextrin(γ-CD)/PEO-PPO-PEO(F127).This approach differs from the conventional softtemplating method in that,apart from the assembly of the monomicelles that leads to the host nanospheres(approximately 300 nm),theγ-CD-containing monomicelles themselves are converted to small porous carbon nanospheres(<10 nm),which results in an ultralow LPPS of 10 nm,representing the bestknown pore connectivity of the HPC family.The HPC-NS delivers a high specific capacitance(405 F g^(-1)at 1 A g^(-1)and 71%capacitance retention at 200 A g^(-1)),wide voltage window(up to 1.6 V),and simultaneously high energy and power densities(24.3 Wh kg^(-1)at a power density of 151 W kg^(-1)and 9 Wh kg^(-1)at 105 W kg^(-1))in aqueous electrolytes.This new strategy boosts the development of porous carbon electrodes for aqueous supercapacitors with simultaneously high power and energy densities.Lei Yao Junsheng Lin Yuanyuan Chen Xiujuan Li Dongrui Wang Haitao Yang Libo Deng Zijian Zheng 2022InfoMat2022,4,4:1

16Low friction of superslippery and superlubricity:A review显示文摘The issues regarding energy dissipation and component damage caused by the interface friction between a friction pair attract enormous attention to friction reduction.The key-enabling technique to realize friction reduction is the use of lubricants.The lubricants smooth the contact interfaces,achieving an ultralow friction contact,which is called superslippery or superlubricity.At present,superslippery and superlubricity are two isolated research topics.There is a lack of unified definition on superslippery and superlubricity from the viewpoint of tribology.Herein,this review aims at exploring the differences and relations between superslippery and superlubricity from their origin and application scenarios.Meanwhile,the challenges for developing superslippery surface and superlubricity surface are discussed.In addition,perspectives on the interactive development of these two surfaces are presented.We hope that our discussion can provide guidance for designing superslippery or superlubricity surfaces by using varies drag-reduction technologies.Zijian ZHENG Zhiguang GUO Weimin LIU Jianbin LUO 2023Friction2023,11,7:1
17Crumpled,high-power,and safe wearable Lithium-Ion Battery enabled by nanostructured metallic textiles显示文摘Textile-based flexible Lithium-Ion Batteries(LIBs)show promising mechanical flexibility that is appealing for a wide variety of wearable and flexible electronic applications.The flexibility of flexible LIBs nowadays is still limited.In addition,their power performance is too low to enable high-speed charging,due to the low conductivity of the textiles.Here,we develop highly electrically conductive metallic fabrics,which are fabricated by coating nanostructured Ni or Cu(nano-reliefs)on woven cotton fabrics,as current collectors to enable crumpled,high-power,and safe wearable LIBs.The nanostructured metal coating not only effectively increases the contact area between current collectors and active materials,but also shortens the charge carrier transport paths,so that LIBs constructed on these nanostructured metallic cotton fabrics exhibit a high power density of 439 W/L and superior electrochemical stability under various mechanical deformations including folding,twisting,squeezing,and impacting.This type of nanostructured metallic textile is highly desirable for portable and wearable electronic applications.Dongrui Wang Jian Chang Qiyao Huang Dongdong Chen Peng Li Yau-Wai Denis Yu Zijian Zheng 2021Fundamental Research2021,1,4:1

20Interpretation of the Protocol for Prevention and Control of COVID-19 in China (Edition 7)显示文摘After coronavirus disease 2019(COVID-19),previously known as pneumonia of unknown etiology(PUE)and 2019 novel coronavirus(2019-nCoV),was first discovered in Wuhan City,Hubei Province,the Chinese government took measures to stop the spread of the epidemic nationwide and interrupted local transmission in China(1–2).Although there have been several localized outbreaks that were caused by overseas importation of the virus—including Heilongjiang,Jilin,Beijing,Liaoning,and other provincial-level administrative divisions(PLADs)—these outbreaks have been stopped within two to four weeks and were limited in scope to less than ten cases or a few hundred cases for each event.With the COVID-19 pandemic still uncontrolled globally,the threat of importing the virus continues unabated and still threatens China’s population,virtually all of which is susceptible.Canjun Zheng Zhaorui Chang Fengfeng Liu Mengjie Geng Hui Chen Jingwei Jiang Sheng Zhou Lu Ran Zhongjie Li Zijian Feng George F.Gao Liping Wang 2020China CDC weekly2020,2,47:1
