| 1 | Preparation of Gd_2O_3:Eu^(3+) downconversion luminescent material and its application in dye-sensitized solar cells显示文摘Gd_2O_3 :Eu^(3+) downconversion luminescent powder was prepared using the homogeneous precipitation method. Its optical properties were analyzed and it was introduced into a dye-sensitized solar cell (DSSC). As a luminescence medium, Gd_2O_3 :Eu^(3+) improved light harvesting via conversion luminescence and increased the photocurrent of the DSSC. As a p-type dopant insulating rare earth oxides form an energy barrier, and the Gd_2O_3 :Eu^(3+) elevated the energy level of the oxide film and increased the photovoltage. The photoelectric conversion efficiency for a DSSC with Gd_2O_3 :Eu^(3+) doping (6 : 100) reached 7.01%, which was 17.4% higher than the photoelectrical conversion efficiency of a DSSC without Gd 2 O 3 :Eu 3+ doping. | LI QingBei LIN JianMing WU JiHuai LAN Zhang WANG JiangLi WANG Yue PENG FuGuo HUANG MiaoLiang XIAO YaoMing | 2011 | Chinese Science Bulletin2011，56，28： | 5 |
| 2 | Epidemiological Investigation of an Inhalational Anthrax Patient Traveling for Medical Treatment in Beijing Municipality,China,August 2021显示文摘Summary What is already known about this topic?Inhalational anthrax,also known as pulmonary anthrax,is an infectious disease caused by Bacillus anthracis.The patients are usually infected by inhaling aerosolized B.anthracis spores from dead animals or animal products.Compared to cutaneous anthrax,inhalational anthrax is rare and deadly and few cases in China were reported.What is added by this report?This report covers all information of clinical features,laboratory testing,and epidemiological characteristics as well as exposure history of a recent primary inhalational anthrax patient who was seeking medical treatment in Beijing Municipality in August 2021.New laboratory techniques,including second-generation sequencing,polymerase chain reaction,and rapid test for serum antibody,played an important role in the process.What are the implications for public health practice?The information provided in this report,including the correct sample type,epidemiological investigation details,and application of the new diagnostic criteria of anthrax,could assist public health professionals in dealing with anthrax epidemics. | Changying Lin Xiangfeng Dou Daitao Zhang Yinqi Sun Huiqiang Han Chunzhi Chen Xiaojun Zhang Shuang Li Yanwei Chen Hongbin Zhang Bin Wang Zhichao Liang Xin Zhang Feng Wei Jiangli Wang Feng Liu Quanyi Wang Jian Shi Peng Yang | 2022 | China CDC weekly2022，4，1： | 3 |
| 3 | FILTERING OF MEDICAL ULTRASONIC IMAGES BASED ON A MODIFIED ANISTROPIC DIFFUSION EQUATION显示文摘Speckle noise reduction is a key problem of the image analysis of medical UltraSound images. In this paper, two important improvements have been developed to a fast anisotropic diffusion algorithm for speckle noise reduction. The Gaussian filter is firstly used before gradient calculation, and then the adaptive algorithm of the factor k is proposed. Numerous experimental results show that the proposed model is superior to other methods in noise removal, fidelity and edge preservation. It is suitable for the preprocessing of a great number of medical UltraSound images, such as three dimen- sional reconstruction. | Wang Ling Li Deyu Wang Tianfu Lin Jiangli Peng Yun Rao Li Zheng Yi | 2007 | Journal of Electronics(China)2007，24，2： | 3 |
| 4 | Application of a novel redox-active electrolyte in MnO_2-based supercapacitors显示文摘This paper reports a novel strategy for preparing redox-active electrolyte through introducing a redox-mediator(p-phenylenediamine,PPD) into KOH electrolyte for the application of ball-milled MnO 2-based supercapacitors.The morphology and compositions of ball-milled MnO 2 were characterized using scanning electron microscopy(SEM) and X-ray diffraction(XRD).The electrochemical properties of the supercapacitor were evaluated by cyclic voltammetry(CV),galvanostatic charge-discharge(GCD),and electrochemical impedance spectroscopy(EIS) techniques.The introduction of p-phenylenediamine significantly improves the performance of the supercapacitor.The electrode specific capacitance of the supercapacitor is 325.24 F g-1,increased by 6.25 folds compared with that of the unmodified system(44.87 F g-1) at the same current density,and the energy density has nearly a 10-fold increase,reaching 10.12 Wh Kg-1.In addition,the supercapacitor exhibits good cycle-life stability. | YU HaiJun WU JiHuai FAN LeQing LIN YouZhen CHEN ShuHong CHEN Yuan WANG JiangLi HUANG MiaoLiang LIN JianMing LAN Zhang HUANG YunFang | 2012 | Science China Chemistry2012，55，7： | 3 |

| 6 | Enhancement of morphological and emission stability of deep-blue small molecular emitter via a universal side-chain coupling strategy for optoelectronic device显示文摘Film morphology of emissive layers is crucial to the performance and stability of solution-processable organic light-emitting diodes(OLEDs). Compared to the interpenetration of conjugated polymer chain,small molecular emitter with a flexible side chain always presents easily aggregation upon external treatment, and caused π-electronic coupling, which is undesirable for the efficiency and stability of deep-blue OLEDs. Herein, we proposed a side-chain coupling strategy to enhance the film morphological an emission stability of solution-processable small molecular deep-blue emitter. In contrary to “parent” MC8 TPA,the crosslinkable styryl and vinyl units were introduced as ended unit at the side-chain of Cm TPA and OEYTPA. Interestingly, Cm TPA and OEYTPA films present a relatively stable morphology and uniform deep-blue emission after thermal annealing(160 ℃) in the atmosphere, different to the discontinuous MC8 TPA annealed film. Besides, compared to the Cm TPA and OEYTPA ones, serious polaron formation in the MC8 TPA annealed film also negative to the deep-blue emission, according to transient absorption analysis. Therefore, both Cm TPA and OEYTPA annealed film obtained at 140 ℃ present an excellent deep-blue ASE behavior with a 445 nm, but absence for MC8 TPA ones, associated with the disruption of annealed films. Finally, enhancement of device performance based on Cm TPA and OEYTPA film(~40%)after thermal annealing with a similar performance curves also confirmed the assumption above. Therefore, these results also supported the effectiveness of our side-chain coupling strategy for optoelectronic applications. | Ning Sun Han Gao Lili Sun Jingxi An Man Xu Chen Sun Yamin Han Jinyi Lin Jiangli Cai Mingjian Ni Liangliang He Jinghao Yang Zhoulu Wang Lubing Bai Xinwen Zhang Qi Wei Xuehua Ding Chengrong Yin Linghai Xie Wei Huang | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
