| 1 | NbN superconducting nanowire single photon detector with efficiency over 90% at 1550 nm wavelength operational at compact cryocooler temperature显示文摘The rapid development of superconducting nanowire single-photon detectors over the past decade has led to numerous advances in quantum information technology. The record for the best system detection efficiency at an incident photon wavelength of 1550 nm is 93%. This performance was attained from a superconducting nanowire single-photon detector made of amorphous WSi; such detectors are usually operated at sub-Kelvin temperatures. In this study, we first demonstrate superconducting nanowire single-photon detectors made of polycrystalline NbN with system detection efficiency of 90.2% for 1550-nm-wavelength photons at2.1 K, accessible with a compact cryocooler. The system detection efficiency saturated at 92.1% when the temperature was lowered to 1.8 K. We expect the results lighten the practical and high performance superconducting nanowire single-photon detectors to quantum information and other high-end applications. | WeiJun Zhang LiXing You Hao Li Jia Huang ChaoLin Lv Lu Zhang XiaoYu Liu JunJie Wu Zhen Wang XiaoMing Xie | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，12： | 9 |
| 2 | Post-mortem tissue proteomics reveals the pathogenesis of multi-organ injuries of COVID-19显示文摘Multi-organ injuries are a major complication of severe Coronavirus Disease 2019(COVID-19).However,its pathogenesis is barely understood.Herein;we profile host responses to fatal SARS-CoV-2 infection by performing quantitative proteomics of 19 post-mortem samples of 8 different organs or tissues,including lungs,liver,intestine,kidney;spleen,brain,heart and muscle,from 3 deceased COVID-19 victims during the first wave of the pandemic(Supplementary Fig.S1A and B,Tables SI-S3). | Yang Qiu Di Wu Wanshan Ning Jiqian Xu Ting Shu Muhan Huang Rong Chen Jiancheng Zhang Yang Han Qingyu Yang Ruiting Li Xiaobo Yang Yaxin Wang Xiaojing Zou Shangwen Pan Chaolin Huang Yu Xue You Shang Xi Zhou | 2021 | National Science Review2021，8，11： | 1 |
| 3 | Recent advances in modification strategies of silicon-based lithiumion batteries显示文摘As potential alternatives to graphite,silicon(Si)and silicon oxides(SiO_(x))received a lot of attention as anode materials for lithiumion batteries owing to their relatively low working potentials,high theoretical specific capacities,and abundant resources.However,the commercialization of Si-based anodes is greatly hindered by their massive volume expansion,low conductivity,unstable solid electrolyte interface(SEI),and low initial Coulombic efficiency(ICE).Continuous endeavors have been devoted to overcoming these challenges to achieve practical usage.This review is centered on the major challenges and latest developments in the modification strategies of Si-based anodes,including structure optimization,surface/interface regulation,novel binders,and innovative design of electrolyte.Finally,outlooks and perspectives of Si-based anodes for future development are presented. | Wenlei Wang Yu Wang Lixuan Yuan Chaolin You Junwei Wu Lili Liu Jilei Ye Yunling Wu Lijun Fu | 2023 | Nano Research2023，16，3： | 1 |
| 4 | Patients with Prolonged Positivity of SARS-CoV-2 RNA Benefit from Convalescent Plasma Therapy:A Retrospective Study显示文摘Convalescent plasma therapy has been implemented in a few cases of severe coronavirus disease 2019.No report about convalescent plasma therapy in treating patients with prolonged positivity of SARS-CoV-2 RNA has been published.In this study,we conducted a retrospective observational study in 27 patients with prolonged positivity of SARS-CoV-2 RNA,the clinical benefit of convalescent plasma therapy were analyzed.q RT-PCR test of SARS-CoV-2 RNA turned negative(B 7 days)in a part of patients(early negative group,n=15)after therapy,others(late negative group,n=12)turned negative in more than 7 days.Pulmonary imaging improvement was confirmed in 7 patients in early negative group and 8 in late negative group after CP therapy.Viral load decreased in early negative group compared with late negative group at day 3,5,7 after implementing convalescent plasma therapy.Patients in early negative group had a shorter median length of hospital stay.In conclusion,convalescent plasma therapy might help eliminate virus and shorten length of hospital stay in patients with prolonged positivity of SARS-CoV-2 RNA. | Yongran Wu Ke Hong Lianguo Ruan Xiaobo Yang Jiancheng Zhang Jiqian Xu Shangwen Pan Lehao Ren Lu Chen Chaolin Huang You Shang | 2020 | Virologica Sinica2020，35，6： | 1 |
| 5 | Longitudinal Characteristics of T Cell Responses in Asymptomatic SARS-CoV-2 Infection显示文摘Dear Editor,SARS-Co V-2 causes a spectrum of illness,ranging from an asymptomatic state to life-threatening multi-organ failure,and imposes a high socioeconomic burden on its sufferers and on society(Chen et al.2020;Pan et al.2020). | Jingyi Yang Ejuan Zhang Maohua Zhong Qingyu Yang Ke Hong Ting Shu Dihan Zhou Jie Xiang Jianbo Xia Xi Zhou Dingyu Zhang Chaolin Huang You Shang Huimin Yan | 2020 | Virologica Sinica2020，35，6： | 1 |
| 6 | Broad phenotypic alterations and potential dysfunction of lymphocytes in individuals clinically recovered from COVID-19显示文摘Although millions of patients have clinically recovered from COVID-19,little is known about the immune status of lymphocytes in these individuals.In this study,the peripheral blood mononuclear cells of a clinically recovered(CR)cohort were comparatively analyzed with those of an age-and sex-matched healthy donor cohort.We found that CD8^(+)T cells in the CR cohort had higher numbers of effector T cells and effector memory T cells but lower Tc1(IFN-γ^(+)),Tc2(IL-4^(+)),and Tc17(IL-17A^(+))cell frequencies.The CD4^(+)T cells of the CR cohort were decreased in frequency,especially the central memory T cell subset.Moreover,CD4^(+)T cells in the CR cohort showed lower programmed cell death protein 1(PD-1)expression and had lower frequencies of Th1(IFN-γ^(+)),Th2(IL-4^(+)),Th17(IL-17A^(+)),and circulating follicular helper T(CXCR5^(+)PD-1^(+))cells.Accordingly,the proportion of isotype-switched memory B cells(IgM−CD20^(hi))among B cells in the CR cohort showed a significantly lower proportion,although the level of the activation marker CD71 was elevated.For CD3−HLA-DR−lymphocytes in the CR cohort,in addition to lower levels of IFN-γ,granzyme B and T-bet,the correlation between T-bet and IFN-γ was not observed.Additionally,by taking into account the number of days after discharge,all the phenotypes associated with reduced function did not show a tendency toward recovery within 4-11 weeks.The remarkable phenotypic alterations in lymphocytes in the CR cohort suggest that severe acute respiratory syndrome coronavirus 2 infection profoundly affects lymphocytes and potentially results in dysfunction even after clinical recovery. | Jingyi Yang Maohua Zhong Ejuan Zhang Ke Hong Qingyu Yang Dihan Zhou Jianbo Xia Yao-Qing Chen Mingbo Sun Bali Zhao Jie Xiang Ying Liu Yang Han Mengxin Xu Xi Zhou Chaolin Huang You Shang Huimin Yan | 2021 | Journal of Molecular Cell Biology2021，13，3： | 0 |
