| 3 | Growth of 12-inch uniform monolayer graphene film on molten glass and its application in PbI2-based photodetector显示文摘Direct growth of large area uniform graphene on functional insulating materials is essential for engineering versatile applications of graphene. However, the existing synthesis approaches can hardly avoid the generation of non-uniform multilayer graphene along the gas flow direction, affording huge challenges for further scaling up. Herein, by exploiting the molten state of soda-lime glass, we have accomplished the direct growth of large area uniform (up to 30 cm × 6 cm) graphene via a facile chemical vapor deposition route on low cost soda-lime glass. The use of molten glass eliminates the chemically active sites (surface corrugations, scratches, defects), and improves the mobility of carbon precursors, affording uniform nucleation and growth of monolayer graphene. Intriguingly, thus-obtained graphene acts as an ideal coating layer for the surface crystallographic modification of soda-lime glass, making it epitaxy substrates for synthesizing high-quality PbI2 nanoplates and continues films. Accordingly, a prototype photodetector was fabricated to present excellent photoelectrical properties of high responsivity (~ 600 on/off current ratio) and fast response speed (18 μs). This work hereby paves ways for the batch production and the direct applications of graphene glass as platforms for constructing high performance electronic and optoelectronic devices. | Zhaolong Chen Haina Ci Zhenjun Tan Zhipeng Dou Xu-dong Chen Bingzhi Liu Ruojuan Liu Li Lin Lingzhi Cui Peng Gao Hailin Peng Yanfeng Zhang Zhongfan Liu | 2019 | Nano Research2019，12，8： | 1 |
| 4 | Review and prospect of maintenance technology for traction system of high-speed train显示文摘In the past few decades,high-speed trains have witnessed tremendous and vigorous development with the appearance of the oil crisis and industrialization,which became a significant trend in the transportation industry the world over.With the increase of high-speed railway mileage,the amount of high-speed train has grown sharply,the service life of the trains has increased gradually and the components of the vehicle traction system have become worn and aged as a result.Therefore,advanced maintenance technology and its application are key factors to reduce maintenance cost,human resource input and ensure safe,stable and reliable operation of trains.This paper summarizes and discusses the development,application mode,maintenance management and maintenance technology of high-speed railways of the major countries in the world,especially discusses the condition-based maintenance and the key technology of the traction electrical system,and offers the prospect of research direction and the development of traction maintenance technology. | Shaolong Xu Chunyang Chen Zhenjun Lin Xiao Zhang Jisheng Dai Liangjie Liu | 2021 | Transportation Safety and Environment2021，3，3： | 0 |

| 6 | Characteristics and Geological Significance of Aeromagnetic Data in Taiyuan,Shanxi,China显示文摘The study area is located in the central part of Shanxi Province,between Qinling Tectonic Belt and Yinshan Tectonic Belt,which is an important part of North China Platform;General direction of the structural line is NNE,with clear geological structure outline and developed structural features.The study area has complex regional geological structure,intense tectonic movement and frequent magmatic activities.Based on the latest high-precision aeromagnetic data,integrated interpretation was completed,combining with the existing geological and geophysical research results.According to the block features in different zones of the RTP aeromagnetic data,this article thoroughly studied the characteristics of aeromagnetic anomalies and found the relationship between aeromagnetic anomalies and surface geological information,and the fault distribution,magmatic rock distribution and magnetic characteristics in this area are discussed. | Ming Wang Xiaoxing Lin Zhenjun Liu Fang Li | 2021 | Earthquake Research Advances2021，1，S01： | 0 |
| 7 | Quantitative analysis of the impact of various urban socioeconomic indicators on search-engine-based estimation of COVID-19 prevalence显示文摘Numerous studies have proposed search engine-based estimation of COVID-19 prevalence during the COVID-19 pandemic;however,their estimation models do not consider the impact of various urban socioeconomic indicators(USIs).This study quantitatively analysed the impact of various USIs on search engine-based estimation of COVID-19 prevalence using 15 USIs(including total population,gross regional product(GRP),and population density)from 369 cities in China.The results suggested that 13 USIs affected either the correlation(SC-corr)or time lag(SC-lag)between search engine query volume and new COVID-19 cases(p<0.05).Total population and GRP impacted SC-corr considerably,with their correlation coefficients r for SC-corr being 0.65 and 0.59,respectively.Total population,GRP per capita,and proportion of the population with a high school diploma or higher had simultaneous positive impacts on SC-corr and SC-lag(p<0.05);these three indicators explained 37e50%of the total variation in SC-corr and SC-lag.Estimations for different urban agglomerations revealed that the goodness of fit,R2,for search engine-based estimation was more than 0.6 only when total urban population,GRP per capita,and proportion of the population with a high school diploma or higher exceeded 11.08 million,120,700,and 38.13%,respectively.A greater urban size indicated higher accuracy of search engine-based estimation of COVID-19 prevalence.Therefore,the accuracy and time lag for search engine-based estimation of infectious disease prevalence can be improved only when the total urban population,GRP per capita,and proportion of the population with a high school diploma or higher are greater than the aforementioned thresholds. | Ligui Wang Mengxuan Lin Jiaojiao Wang Hui Chen Mingjuan Yang Shaofu Qiu Tao Zheng Zhenjun Li Hongbin Song | 2022 | Infectious Disease Modelling2022，7，2： | 0 |
