| 1 | Q-switching of waveguide lasers based on graphene/WS_2 van der Waals heterostructure显示文摘We report on the operation of passively Q-switched waveguide lasers at 1 μm wavelength based on a graphene∕WS_2 heterostructure as a saturable absorber(SA). The gain medium is a crystalline Nd:YVO_4 cladding waveguide produced by femtosecond laser writing. The nanosecond waveguide laser operation at 1064 nm has been realized with the maximum average output power of 275 m W and slope efficiency of 37%. In comparison with the systems based on single WS_2 or graphene SA, the lasing Q-switched by a graphene∕WS_2 heterostructure SA possesses advantages of a higher pulse energy and enhanced slope efficiency, indicating the promisingapplications of van der Waals heterostructures for ultrafast photonic devices. | ZIQI LI CHEN CHENG NINGNING DONG CAROLINA ROMERO QINGMING LU JUN WANG JAVIER RODRíGUEZ VáZQUEZ DE ALDANA YANG TAN FENG CHEN | 2017 | Photonics Research2017，5，5： | 7 |
| 2 | Distribution and their pollution assessment of heavy metals in the sediments of the Yalu River Estuary and its adjacent coastal waters显示文摘The present paper deals with the distribution patterns of heavy metals and the associated influencing factors in the Yalu River Estuary and its adjacent coastal waters.Based upon the analysis of the surficial and core sediments measurements,the pollution of heavy metal and potential ecological risk were evaluated.The burial flux and contents of heavy metals(except for copper) have been continuously increasing since the 1920s.Therefore,the gross potential ecological risk for the sedi-ments was high or very high,and the study area was endangered by heavy metals contamination.Heavy metals originated mainly from upstream pollutant input,correlation analysis showed that chromium,nickel,zinc,cadmium,lead,arsenic,and mercury in the sediments of the middle and west channels as well as the sea area of the western Yalu River Estuary concentrations were most probably derived from similar sources.In contrast,the metal of copper most probably originated from sources different from the other metals.Preliminary studies indicate that copper contamination was most likely the result of emission from mining activities situated at the upstream of the river.The contents of heavy metals in the sediments of estuarine turbidity maximum zone of Yalu River were larger than those of any other areas in the middle channel.With large portion of fine sediments,weaker hydrodynamics,and richer sources of heavy metals,the sediments of the west channel,were even more enriched with heavy metals than those of the middle channel. | GAO Jianhua LI Jun Wang Harry V WANG Yaping WANG Zhenyan BAI Fenglong GAO Shu CHENG Yan | 2009 | Acta Oceanologica Sinica2009，28，6： | 4 |
| 3 | SPH-BEM simulation of underwater explosion and bubble dynamics near rigid wall显示文摘A process of underwater explosion of a charge near a rigid wall includes three main stages: charge detonation, bubble pulsation and jet formation. A smoothed particle hydrodynamics(SPH) method has natural advantages in solving problems with large deformations and is suitable for simulation of processes of charge detonation and jet formation. On the other hand, a boundary element method(BEM) is highly efficient for modelling of the bubble pulsation process. In this paper, a hybrid algorithm, fully utilizing advantages of both SPH and BEM, was applied to simulate the entire process of free and near-field underwater explosions. First, a numerical model of the free-field underwater explosion was developed, and the entire explosion process–from the charge detonation to the jet formation–was analysed. Second, the obtained numerical results were compared with the original experimental data in order to verify the validity of the presented method. Third, a SPH model of underwater explosion for a column charge near a rigid wall was developed to simulate the detonation process. The results for propagation of a shock wave are in good accordance with the physical observations. After that, the SPH results were employed as initial conditions for the BEM to simulate the bubble pulsation. The obtained numerical results show that the bubble expanded at first and then shrunk due to a differences of pressure levels inside and outside it. Here, a good agreement between the numerical and experimental results for the shapes, the maximum radius and the movement of the bubble proved the effectiveness of the developed numerical model. Finally, the BEM results for a stage when an initial jet was formed were used as initial conditions for the SPH method to simulate the process of jet formation and its impact on the rigid wall. The numerical results agreed well with the experimental data, verifying the feasibility and suitability of the hybrid algorithm. Besides, the results show that, due to the effect of the Bjerknes force, a jet with a high speed was formed that may cause local damage to underwater structures. | ZHANG ZhiFan WANG Cheng ZHANG A-Man Silberschmidt Vadim V WANG LongKan | 2019 | Science China(Technological Sciences)2019，62，7： | 3 |
| 4 | 2021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://gffzz16e312a87a7141a5hv9x5wqq0k6nf6uuv.ffgz.tsg.suse.edu.cn/A978). | Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun | 2022 | Chinese Medical Journal2022，，8： | 2 |
