| 1 | Exploitation of Bi2O2Se/graphene van der Waals heterojunction for creating efficient photodetectors and short-channel field-effect transistors显示文摘The formation of heterojunction within solid-state devices enables them with eventually high performances,but provides a challenge for material synthesis and device fabrication because strict conditions such as lattice match are needed.Herein,we show a facile method to fabricate a van der Waals(vdW)heterojunction between two-dimensional(2D)bismuth oxyselenide(Bi2O2Se)and graphene,during which the graphene is directly transferred to the Bi2O2Se and served as a lowcontract-resistant electrode with small work function mismatch(~50 meV).As an optoelectronic device,the Bi2O2Se/graphene vdW heterojunction allows for the efficient sensing toward 1200-nm incident laser.Regarding the application of fieldeffect transistors(FETs),the short-channel(50 nm)sample can be synthesized by utilizing these two 2D materials(ie,channel:Bi2O2Se;drain/source terminal:graphene)and the n-type characteristic can be observed with the accordant field modulation.It is confirmed that we show a simple way to prepare the vdW heterojunction which is aiming to the high-performance applications among optoelectronics and FETs. | Congwei Tan Shipu Xu Zhenjun Tan Luzhao Sun Jinxiong Wu Tianran Li Hailin Peng | 2019 | InfoMat2019，1，3： | 8 |
| 2 | A Scenario-Based Evaluation of COVID-19-Related Essential Clinical Resource Demands in China显示文摘The coronavirus disease 2019(COVID-19)pandemic is a global crisis,and medical systems in many countries are overwhelmed with supply shortages and increasing demands to treat patients due to the surge in cases and severe illnesses.This study aimed to assess COVID-19-related essential clinical resource demands in China,based on different scenarios involving COVID-19 spreads and interventions.We used a susceptible–exposed–infectious–hospitalized/isolated–removed(SEIHR)transmission dynamics model to estimate the number of COVID-19 infections and hospitalizations with corresponding essential healthcare resources needed.We found that,under strict non-pharmaceutical interventions(NPIs)or mass vaccination of the population,China would be able to contain community transmission and local outbreaks rapidly.However,under scenarios involving a low intensity of implemented NPIs and a small proportion of the population vaccinated,the use of a peacetime–wartime transition model would be needed for medical source stockpiles and preparations to ensure a normal functioning healthcare system.The implementation of COVID-19 vaccines and NPIs in different periods can influence the transmission of COVID-19 and subsequently affect the demand for clinical diagnosis and treatment.An increased proportion of asymptomatic infections in simulations will not reduce the demand for medical resources;however,attention must be paid to the increasing difficulty in containing COVID-19 transmission due to asymptomatic cases.This study provides evidence for emergency preparations and the adjustment of prevention and control strategies during the COVID-19 pandemic.It also provides guidance for essential healthcare investment and resource allocation. | Ting Zhang Qing Wang Zhiwei Leng Yuan Yang Jin Yang Fangyuan Chen Mengmeng Jia Xingxing Zhang Weiran Qi Yunshao Xu Siya Chen Peixi Dai Libing Ma Luzhao Feng Weizhong Yang | 2021 | Engineering2021，7，7： | 7 |
| 3 | Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process. | Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

| 4 | The Incoming Influenza Season—China,the United Kingdom,and the United States,2021–2022显示文摘Introduction:Seasonal influenza activity has declined globally since the widespread of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)transmission.There has been scarce information to understand the future dynamics of influenza—and under different hypothesis on relaxation of nonpharmaceutical interventions(NPIs)in particular—after the disruptions to seasonal patterns.Methods:We collected data from public sources in China,the United Kingdom,and the United States,and forecasted the influenza dynamics in the incoming 2021–2022 season under different NPIs.We considered Northern China and Southern China separately,due to the sharp difference in the patterns of seasonal influenza.For the United Kingdom,data were collected for England only.Results:Compared to the epidemics in 2017–2019,longer and blunter influenza outbreaks could occur should NPIs be fully lifted,with percent positivity varying from 10.5 to 18.6 in the studying regions.The rebounds would be smaller if the maskwearing intervention continued or the international mobility stayed low,but sharper if the mask-wearing intervention was lifted in the middle of influenza season.Further,influenza activity could stay low under a much less stringent mask-wearing intervention coordinated with influenza vaccination.Conclusions:The results added to our understandings of future influenza dynamics after the global decline during the coronavirus disease 2019(COVID-19)pandemic.In light of the uncertainty on the incoming circulation strains and the relatively low negative impacts of mask wearing on society,our findings suggested that wearing mask could be considered as an accompanying mitigation measure in influenza prevention and control,especially for seasons after long periods of low-exposure to influenza viruses.Seasonal influenza activity declines globally during the coronavirus disease 2019(COVID-19)pandemic(1–4).For instance,in China,influenza activity,as measured by percentage of submitted specimens testing positive,dropped from 11.8%to 2.0%in 2020–2021 influenza season,compared to the past 5 years(5).The long-period of low-exposure to influenza viruses adds great uncertainty on preparedness for the incoming 2021–2022 influenza season.Influenza vaccination is one of the most effective measures in seasonal influenza prevention and control,but with only a few influenza viruses circulating,it could be difficult to determine the targeted strains for vaccination.In this context,it is of primary importance to identify alternative mitigation measures for the incoming 2021–2022 influenza season,the first season after long periods of virtually no influenza outbreaks worldwide.Using data from China,the United Kingdom,and the United States,we forecasted the influenza activity in the incoming 2021–2022 influenza season under hypothetical scenarios without non-pharmaceutical interventions(NPIs)and with different assumptions on mask-wearing and mobility levels. | Shasha Han Ting Zhang Yan Lyu Shengjie Lai Peixi Dai Jiandong Zheng Weizhong Yang Xiaohua Zhou Luzhao Feng | 2021 | China CDC weekly2021，3，49： | 3 |
| 5 | One Hundred Years of Influenza Since the 1918 Pandemic—Is China Prepared Today?显示文摘Almost 100 years after the 1918 influenza pandemic,China experienced its largest,most widespread epidemic of human infections with avian influenza A(H7N9),the influenza virus with the greatest pandemic potential of all influenza viruses assessed to date by the United States Centers for Disease Control and Prevention’s Influenza Risk Assessment Tool.This historical review describes how China was affected by the 1918,1958,1968,and 2009 influenza pandemics,records milestones in China’s capacity to detect and respond to influenza threats,and identifies remaining challenges for pandemic preparedness.This review suggests that past influenza pandemics have improved China’s national capabilities such that China has become a global leader in influenza detection and response.Further enhancing China’s pandemic preparedness to address remaining challenges requires government commitment and increased investment in China’s public health and healthcare systems. | Ran Zhang Xiaoping Dong Dayan Wang Luzhao Feng Lei Zhou Ruiqi Ren Carolyn Greene Ying Song Alexander J.Millman Eduardo Azziz-Baumgartner Zijian Feng | 2019 | China CDC weekly2019，1，4： | 2 |

| 8 | Association between influenza vaccination and SARS-CoV-2 infection and its outcomes: systematic review and meta-analysis显示文摘Background:World Health Organization recommends that influenza vaccines should benefit as much of the population as possible,especially where resources are limited.Corona virus disease 2019(COVID-19)has become one of the greatest threats to health systems worldwide.The present study aimed to extend the evidence of the association between influenza vaccination and COVID-19 to promote the former.Methods:In this systematic review,four electronic databases,including the Cochrane Library,PubMed,Embase,and Web of Science,were searched for related studies published up to May 2022.All odds ratios(ORs)with 95%confidence intervals(CIs)were pooled by meta-analysis.Results:A total of 36 studies,encompassing 55,996,841 subjects,were included in this study.The meta-analysis for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection provided an OR of 0.80(95%CI:0.73–0.87).The statistically significant estimates for clinical outcomes were 0.83(95%CI:0.72–0.96)for intensive care unit admission,0.69(95%CI:0.57–0.84)for ventilator support,and 0.69(95%CI:0.52–0.93)for fatal infection,while no effect seen in hospitalization with an OR of 0.87(95%CI:0.68–1.10).Conclusion:Influenza vaccination helps limit SARS-CoV-2 infection and severe outcomes,but further studies are needed.Registration:PROSPERO,CRD42022333747. | Binshan Jiang Qiangru Huang Mengmeng Jia Xinai Xue Qing Wang Weizhong Yang Luzhao Feng | 2022 | Chinese Medical Journal2022，135，19： | 1 |
| 9 | Increased Incidence of Scarlet Fever--China,1999−2018显示文摘What is already known about this topic?Scarlet fever had high incidence between the 1950s and 1980s,but during the 1980s and 1990s,the incidence of scarlet fever dropped to a relatively low and stable levels in China.What is added by this report?Starting in 2011,scarlet fever incidence significantly increased in China.In the eight years between 2011 and 2018,479,555 cases were reported,which exceeded the total number of 241,365 cases reported in the previous twelve years 1999–2010.What are the implications for public health practice?Both patient and pathogen epidemiological surveillance need to be heightened to monitor serious cases of scarlet fever and to implement timely control measures. | Yuanhai You Ying Qin Mark J.Walker Luzhao Feng Jianzhong Zhang | 2019 | China CDC weekly2019，1，5： | 1 |
| 10 | Decreased influenza vaccination coverage among Chinese healthcare workers during the COVID-19 pandemic显示文摘Background:Healthcare workers(HCWs)were the priority group for influenza vaccination,in China during the 2020/2021 and 2021/2022 influenza seasons.However,vaccination rates in HCWs have always been low.This study investigated influenza vaccination status among Chinese HCWs and analyzed the factors driving vaccination.Methods:We provided electronic questionnaires to HCWs from January 27,2022 to February 21,2022,using the WeChat platform'Breath Circles'.HCWs who received the link could also forward it to their colleagues.Binary logistic regression models were used to analyze vaccination-associated factors among HCWs.Results:Among the 1697 HCWs surveyed,vaccination coverage was 43.7%(741/1697)during the 2020/2021 influenza season,and 35.4%(600/1697)during the 2021/2022 influenza season,as of February 21,2022.Additionally,22.7%(385/1697)and 22.1%(358/1697)of HCWs reported that their workplaces implemented a free vaccination policy for all employees during the 2020/2021 and 2021/2022 influenza seasons.HCWs who were required to be vaccinated according to hospital regulations,and whose hospitals implemented the free influenza vaccine policy were more likely to be vaccinated(2020/2021 and 2021/2022;P<0.05).In addition,the economic level of the HCWs'province(2021/2022,P<0.05)and the HCWs’knowledge about vaccination and willingness to get vaccinated,such as active learning about vaccines(2020/2021,P<0.05),supportive attitude toward vaccination for all HCWs(2020/2021 and 2021/2022;P<0.05),also had an impact on vaccine coverage.Conclusions:A free influenza vaccination policy and workplace required vaccination are effective in improving influenza vaccination coverage among HCWs.Influenza vaccination coverage of Chinese HCWs remained low and showed a downward trend after the COVID-19 outbreak.Further effective measures,such as advocacy campaigns,free vaccine policies,and on-site vaccination could be implemented to improve influenza vaccination coverage. | Libing Ma Xuan Han Yuan Ma Yuan Yang Yunshao Xu Di Liu Weizhong Yang Luzhao Feng | 2022 | Infectious Diseases of Poverty2022，11，5： | 1 |

| 12 | 应急状态下新冠流行曲线预测的方法学研究——基于北京市百度搜索和传统流感样病例监测显示文摘Surveillance is an essential work on infectious diseases prevention and control.When the pandemic occurred,the inadequacy of traditional surveillance was exposed,but it also provided a valuable opportunity to explore new surveillance methods.This study aimed to estimate the transmission dynamics and epidemic curve of severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)Omicron BF.7 in Beijing under the emergent situation using Baidu index and influenza-like illness(ILI)surveillance.A novel hybrid model(multiattention bidirectional gated recurrent unit(MABG)-susceptible-exposed-infected-removed(SEIR))was developed,which leveraged a deep learning algorithm(MABG)to scrutinize the past records of ILI occurrences and the Baidu index of diverse symptoms such as fever,pyrexia,cough,sore throat,anti-fever medicine,and runny nose.By considering the current Baidu index and the correlation between ILI cases and coronavirus disease 2019(COVID-19)cases,a transmission dynamics model(SEIR)was formulated to estimate the transmission dynamics and epidemic curve of SARS-Co V-2.During the COVID-19 pandemic,when conventional surveillance measures have been suspended temporarily,cases of ILI can serve as a useful indicator for estimating the epidemiological trends of COVID-19.In the specific case of Beijing,it has been ascertained that cumulative infection attack rate surpass 80.25%(95%confidence interval(95%CI):77.51%-82.99%)since December 17,2022,with the apex of the outbreak projected to transpire on December 12.The culmination of existing patients is expected to occur three days subsequent to this peak.Effective reproduction number(Rt)represents the average number of secondary infections generated from a single infected individual at a specific point in time during an epidemic,remained below 1 since December 17,2022.The traditional disease surveillance systems should be complemented with information from modern surveillance data such as online data sources with advanced technical support.Modern surveillance channels should be used primarily in emerging infectious and disease outbreaks.Syndrome surveillance on COVID-19 should be established to following on the epidemic,clinical severity,and medical resource demand. | Ting Zhang Liuyang Yang Xuan Han Guohui Fan Jie Qian Xuancheng Hu Shengjie Lai Zhongjie Li Zhimin Liu Luzhao Feng Weizhong Yang | 2023 | Engineering2023，31，12： | 0 |
| 13 | Invisible vapor catalysis in graphene growth by chemical vapor deposition显示文摘Vapor catalysis was recently found to play a crucial role in superclean graphene growth via chemical vapor decomposition(CVD).However,knowledge of vapor-phase catalysis is scarce,and several fundamental issues,including vapor compositions and their impact on graphene growth,are ambiguous.Here,by combining density functional theory(DFT)calculations,an ideal gas model,and a designed experiment,we found that the vapor was mainly composed of Cui clusters with tens of atoms.The vapor pressure was estimated to be~10^(-12)-10^(-1)1 bar under normal low-pressure CVD system(LPCVD)conditions for graphene growth,and the exposed surface area of Cui clusters in the vapor was 22-269 times that of the Cu substrate surface,highlighting the importance of vapor catalysis.DFT calculations show Cu clusters,represented by Cu17,have strong capabilities for adsorption,dehydrogenation,and decomposition of hydrocarbons.They exhibit an adsorption lifetime and reaction flux six orders of magnitude higher than those on the Cu surface,thus providing a sufficient supply of active C atoms for rapid graphene growth and improving the surface cleanliness of the synthesized graphene.Further experimental validation showed that increasing the amount of Cu vapor improved the as-synthesized graphene growth rate and surface cleanliness.This study provides a comprehensive understanding of vapor catalysis and the fundamental basis of vapor control for superclean graphene rapid growth. | Xiucai Sun Xiaoting Liu Zhongti Sun Xintong Zhang Yuzhu Wu Yeshu Zhu Yuqing Song Kaicheng Jia Jincan Zhang Luzhao Sun Wan-Jian Yin Zhongfan Liu | 2024 | Nano Research2024，17，5： | 0 |

| 15 | City-Specific Effects of Lifting Mobility Restrictions—China, February–March 2020显示文摘Summary What is already known about this topic?Government used mobility restrictions to help contain the first wave of coronavirus disease 2019(COVID-19)across cities in China.The restrictions were lifted during times of non-zero incidence in response to a return to work order that went into effect on February 10,2020.What is added by this report?The effect of lifting mobility restrictions on COVID-19 death rate and incidence varied by city,with smaller increases or even reductions in cities with low community connectivity and small floating volume,and larger increases in cities with high community connectivity and large floating volume.Effects on recovery rates were similar across cities.What are the implications for public health practice?City-specific mobility restriction lifting is likely to be beneficial.Two indexes,community connectivity and floating volume,can inform the design of city-specific mobility restriction lifting policies. | Shasha Han Libing Ma Ting Zhang Luzhao Feng Weizhong Yang Xiaoying Zheng | 2022 | China CDC weekly2022，4，31： | 0 |
| 16 | Toward batch synthesis of high-quality graphene by cold-wall chemical vapor deposition approach显示文摘Chemical vapor deposition(CVD)has emerged as a promising approach for the controlled growth of graphene films with appealing scalability,controllability,and uniformity.However,the synthesis of high-quality graphene films still suffers from low production capacity and high energy consumption in the conventional hot-wall CVD system.In contrast,owing to the different heating mode,cold-wall CVD(CW-CVD)system exhibits promising potential for the industrial-scale production,but the quality of as-received graphene remains inferior with limited domain size and high defect density.Herein,we demonstrated an efficient method for the batch synthesis of high-quality graphene films with millimeter-sized domains based on CW-CVD system.With reduced defect density and improved properties,the as-received graphene was proven to be promising candidate material for electronics and anti-corrosion application.This study provides a new insight into the quality improvement of graphene derived from CW-CVD system,and paves a new avenue for the industrial production of high-quality graphene films for potential commercial applications. | Kaicheng Jia Ziteng Ma Wendong Wang Yongliang Wen Huanxin Li Yeshu Zhu Jiawei Yang Yuqing Song Jiaxin Shao Xiaoting Liu Qi Lu Yixuan Zhao Jianbo Yin Luzhao Sun Hailin Peng Jincan Zhang Li Lin Zhongfan Liu | 2022 | Nano Research2022，15，11： | 0 |
| 17 | Porous-structure engineered spacer for high-throughput and rapidgrowth of high-quality graphene films显示文摘Chemical vapor deposition(CVD)in conjunction with batch-to-batch manufacturing process is considered as the most promising technical route for mass-production of high-quality graphene films.To improve the space utilization of the CVD chamber and increase the throughput per batch,stacking of the Cu foil substrates is efficient,but suffers from the problems of adjacent fusion and the poor mass-transfer.Here,we demonstrate an efficient strategy for high-throughput and rapid growth of high-quality graphene by alternate stacking of Cu foils and porous carbon fiber paper(CFP).Relying on the unhindered mass-transfer through the pores of CFPs,full-covered high-quality graphene films on compact-stacked Cu foils were achieved within 2 min.Computational fluid dynamics(CFD)simulation and isotope labeling technique were performed to explore the gas diffusion and graphene growth process in the confined space of the Cu-CFP stacks.This work provides a feasible method for industrial production of graphene films,which may also be used for batch production of other two-dimensional materials. | Ziteng Ma Heng Chen Xiaofeng Song Buhang Chen Qin Li Yanglizhi Li Haiyang Liu Kaicheng Jia Shenghong Huang Luzhao Sun Zhongfan Liu | 2022 | Nano Research2022，15，11： | 0 |
| 18 | Long-term outcomes in COVID-19 patients who recovered from the first wave of the pandemic显示文摘This cross-sectional study evaluated the long-term health effects of coronavirus disease 2019(COVID-19)in Jianghan District(Wuhan,China).The results showed that 61.4%of COVID-19 patients reported at least one symptom and 8.8%had depressive symptoms at the 17-month follow-up.The proportion of patients with chest radiographic abnormalities in Fangcang shelter hospitals and designated COVID-19hospitals was 31.6%and 41.1%,respectively,and the proportion of patients with impaired pulmonary diffusion capacity in these hospitals was 52.8%and 60.9%,respectively.Female sex(odds ratio[OR]=1.48,95%confidence interval[CI]:1.16–1.88),severe disease(OR=1.46,95%CI:1.01–2.10)and a higher number of initial symptoms(OR=1.31,95%CI:1.23–1.40)were associated with the development of sequelae symptoms at 17 months.This study involving community-dwelling COVID-19adults may help determine the long-term effects of COVID-19 during the first pandemic wave.Nonetheless,larger follow-up studies are needed to characterize the post-COVID-19 condition. | Dan Cui Simiao Chen Luzhao Feng Mengmeng Jia Yeming Wang Weijun Xiao Yanxia Sun Qiangru Huang Libing Ma Zhiwei Leng Hao Wang Bin Cao Weizhong Yang Juntao Yang Chen Wang | 2022 | National Science Review2022，9，11： | 0 |
| 19 | Willingness of Caregivers to Have Their Children Vaccinated with Pneumococcal Vaccines in the Context of an Innovative Immunization Strategy—Weifang City,Shandong Province,2021显示文摘Summary What is already known about this topic?Pneumococcal diseases(PDs)pose a serious health threat to children.Vaccination is the most costeffective intervention to prevent PDs,but pneumococcal vaccines coverage among children is low in China.What is added by this report?This study investigated the willingness of children’s caregivers to have their children vaccinated with pneumococcal vaccines under an innovative policy to offer 1-dose of the 13-valent pneumococcal conjugate vaccines at no charge to families.The research found that 70.51%of caregivers were willing to have their infants receive pneumococcal vaccines and that reducing the cost of vaccines may increase caregivers’willingness.What are the implications for public health practice?This is the first evaluation in China of acceptance of pneumococcal vaccines among children under a 1-dose,cost-free policy.The results provide scientific evidence for updating local and national pneumococcal immunization strategies to promote the use of the pneumococcal vaccine. | Yuan Yang Ting Zhang Yan Wang Libing Ma Shuyun Xie Jian Zhou Weiran Qi Qing Wang Peixi Dai Yuanze Du Luzhao Feng Chunping Wang Weizhong Yang | 2022 | China CDC weekly2022，4，20： | 0 |
| 20 | Application of the E-commerce Platform in the International Trade显示文摘E-commerce is a new consumption mode, which develops rapidly and is welcomed by consumers. It also plays an important role in promoting the international trade. Through this analysis, we can understand that the influence of the e-commerce on the international market has both positive and negative aspects. We need to be aware of our shortcomings, understand the gap between them and the developed countries, and formulate the relevant policies. Let China's e-commerce continue to improve and innovate in the international trade, and find a suitable strategy for its own development. Relevant Chinese departments should actively and effectively participate in the construction of e-commerce. On the one hand, they can stabilize the status of e-commerce in the international trade, and on the other hand, they can expand the consumer groups and make the electronic goods better. | ZHOU Luzhao | 2019 | International English Education Research2019，，3： | 0 |
