| 1 | Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. | Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan | 2015 | Light(Science & Applications)2015，4，1： | 47 |
| 2 | Monolithic homogeneous integrated miniaturized triboelectric nanogenerator with an inner air cavity for energy harvesting显示文摘To realize the high-efficiency acquisition of environmental mechanical energy,traditional triboelectric nanogenerators(TENGs)based on contact-separation consist of two separate triboelectric layers.Their large contact-separation gap increases the overall volume of the device,making it difficult to realize miniaturization and flexibility.This work,therefore,presents a fully enclosed all-in-one-shaped flexible TENG(FEAST)with an air cavity using rubber mixing and high-temperature vulcanization.The air pressure inside the enclosed air cavity facilitates effective contact-separation of the FEAST.The homogeneous integration between the triboelectric layer and the electrode layer enhances structural firmness without using extra spacer materials.The developed FEAST presents excellent mechanical durability even after 10000 cycles.By increasing the active contact area between the triboelectric materials,a maximum peak-peak output voltage,current,and power density of 130 V,1.1μA,and277 m W/m^(2),respectively,were obtained with an effective stress area of 1 cm2.Moreover,the fully enclosed structure ensures that the output performance is not affected by the external environment.The FEAST was fixed onto the sole of a shoe to demonstrate its applicability in harvesting mechanical energy from human motions.Overall,the developed method provides a simple approach for optimizing the structure of TENGs and is compatible with large-scale manufacturing. | HOU XiaoJuan ZHANG ShengNan YU JunBin YANG ChangJun ZHANG Ning HE Jian CHOU XiuJian | 2021 | Science China(Technological Sciences)2021，64，3： | 3 |
| 3 | The C_(6)D_(6)detector system on the Back-n beam line of CSNS显示文摘Introduction The neutron capture cross sections are very important in the field of nuclear device design and basic physics research.Hydrogen-free liquid scintillator such as C_(6)D_(6)detectors are widely used in the neutron capture cross-sectional measurements for the low neutron sensitivity and fast time response.The Back-n white neutron source at China Spallation Neutron Source is the first spallation white neutron source in China,and it is suitable for neutron capture cross-sectional measurement.Materials and methods A C_(6)D_(6)detector system was built in the Back-n experimental station.The pulse height weighting technique was used to determine the system’s detection efficiency.The response to gamma rays of the C_(6)D_(6)detector was measured,and the energy resolution function was determined.Monte Carlo simulation with Geant4 code was carried out to get the weighting function of this C_(6)D_(6)detector system.Additionally,the systematic uncertainty of the weighting function was also determined.Conclusion According to the experimental and simulation results,this C_(6)D_(6)detector system can be used to measure neutron capture cross section. | Jie Ren Xichao Ruan Jie Bao Guangyuan Luan Wei Jiang Qi An Huaiyong Bai Ping Cao Qiping Chen Yonghao Chen Pinjing Cheng Zengqi Cui Ruirui Fan Changqing Feng Minhao Gu Fengqin Guo Changcai Han Zijie Han Guozhu He Yongcheng He Yuefeng He Hanxiong Huang Weiling Huang Xiru Huang Xiaolu Ji Xuyang Ji Haoyu Jiang Hantao Jing Ling Kang Mingtao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Rong Liu Shubin Liu Xingyan Liu Yinglin Ma Changjun Ning Binbin Qi Zhaohui Song Hong Sun Xiaoyang Sun Zhijia Sun Zhixin Tan Hongqing Tang Jingyu Tang Pengcheng Wang Qi Wang Taofeng Wang Yanfeng Wang Zhaohui Wang Zheng Wang Jie Wen Zhongwei Wen Qingbiao Wu Xiaoguang Wu Xuan Wu Likun Xie Yiwei Yang Han Yi Li Yu Tao Yu Yongji Yu Guohui Zhang Jing Zhang Linhao Zhang Liying Zhang Qingmin Zhang Qiwei Zhang Xianpeng Zhang Yuliang Zhang Zhiyong Zhang Yingtan Zhao Liang Zhou Zuying Zhou Danyang Zhu Kejun Zhu Peng Zhu | 2019 | Radiation Detection Technology and Methods2019，3，3： | 1 |
| 4 | Preliminary analysis of chemical reaction under the radiation of electromagnetic wave显示文摘Microwave can be used to accelerate chemical reaction and improve the rate of production. Does microwave only act as a heating factor? Do there exist any specific effects? These questions are still holding a violent controversy. Here we will choose the Belousov-Zhabotinsky reaction, which is sensitive to surrounding effects, to study the influence of microwave on chemical reactions. Visible changes of periods have been observed. It appeares that there could have been specific effects of microwave. | Kama Huang Ning Liu Changjun Liu Liping Yan | 2000 | Chinese Science Bulletin2000，45，19： | 1 |
| 5 | Development of a psychosocial functioning questionnaire for patients with major depressive disorder显示文摘Background The importance of psychosocial functioning in the assessment,diagnosis and treatment of major depressive disorder(MDD)is widely recognised.However,there is a lack of effective scales to assess psychosocial functioning in patients with MDD.Aims To develop a professional questionnaire to evaluate the psychosocial functioning of patients with MDD.Methods Using a literature review,an open-ended questionnaire survey,and patient interviews,a theoretical model of psychosocial functioning was constructed,and an initial questionnaire was formed which included four dimensions.After two rounds of testing,using items analysis and exploratory factor analysis,a finalized questionnaire was created.There were 460 patients with MDD selected from six psychiatric hospitals for formal testing using a convenience sampling method.Forty patients were randomly selected and retested one week later to evaluate the test-retest reliability of the scale.The Patient Health Questionnaire-9(PHQ-9),Short Form of Quality of Life Enjoyment and Satisfaction Questionnaire(Q-LES Q SF),Sheehan Disability Scale(SDS),and Dysfunctional Attitudes Scale(DAS)provided major standards to check the criterion validity of this questionnaire.Correlation analysis,confirmatory factor analysis,and internal consistency reliability testing were used to examine other psychometric characteristics of the finalized questionnaire.Results The Psychosocial Functioning Questionnaire(PFQ)for patients with MDD included three dimensions:psychological cognitive functioning,subjective well-being,and social functioning,with a total of 18 items.The overall internal consistency reliability of the questionnaire was 0.957,and the test-retest reliability was 0.840.Confirmatory factor analysis showed that the model fitted well:Goodness of Fit Index(GFI)=0.888;Root Mean SquareError of Approximation(RMSEA)=0.085.The total score of PFQ was significantly correlated with the total score of PHQ-9,DAS,SDS and Q-LES Q SF(|r|=0.599-0.870,p<0.001).Conclusions The Psychosocial Functioning Questionnaire has good reliability and validity.It can be used to measure the psychosocial functioning of patients with MDD. | Xiujuan Zhang Hua Yang Hui Ma Changjun Teng Hui Wang Kaili Diao Ning Zhang | 2022 | General Psychiatry2022，35，1： | 1 |
