7Deciphering the leakage conduction mechanism of BiFeO_(3)–BaTiO_(3)lead-free piezoelectric ceramics显示文摘BiFeO_(3)–BaTiO_(3)(BF–BT)based piezoelectric ceramics are a kind of high-temperature lead-free piezoelectric ceramics with great development prospects due to their high Curie temperature(TC)and excellent electrical properties.However,large leakage current limits their performance improvement and practical applications.In this work,direct current(DC)test,alternating current(AC)impedance,and Hall tests were used to investigate conduction mechanisms of 0.75BiFeO_(3)–0.25BaTiO_(3)ceramics over a wide temperature range.In the range of room temperature(RT)−150℃,ohmic conduction plays a predominant effect,and the main carriers are p-type holes with the activation energy(Ea)of 0.51 eV.When T>200℃,the Ea value calculated from the AC impedance and Hall data is 1.03 eV with oxygen vacancies as a cause of high conductivity.The diffusion behavior of thermally activated oxygen vacancies is affected by crystal symmetry,oxygen vacancy concentration,and distribution,dominating internal conduction mechanism.Deciphering the conduction mechanisms over the three temperature ranges would pave the way for further improving the insulation and electrical properties of BiFeO_(3)–BaTiO_(3)ceramics.Mengping Xue Yucheng Tang Zhihang Shan Yijin Hao Xiaoxiao Zhou Xiaoqi Gao Hezhang Li Jun Pei Boping Zhang 2023Journal of Advanced Ceramics2023,12,10:0
8Enhanced piezoelectric properties and thermal stability of Bi_(0.5)Na_(0.5)TiO_(3)modified BiFeO_(3)-BaTiO_(3)ceramics with morphotropic phase boundary显示文摘Morphotropic phase boundary(MPB)plays a key role in tuning piezoelectric responses of ferroelectric ceramics.Here,Bi_(0.5)Na_(0.5)TiO_(3)modified BiFeO_(3)-BaTiO_(3)ternary solid solutions of 0.7BiFeO_(3)-(0.3-x)BaTiO_(3)-xBi_(0.5)Na_(0.5)TiO_(3)(referred to as BF-BT-xBNT,0.00≤x≤0.04)were prepared for lead-free piezo-electrics.All the ceramics exhibit an MPB with coexisting rhombohedral(R)and tetragonal(T)phases,and the R/T phase ratio decreases upon increasing x.The increment of BNT promotes the grain growth,lowers the leakage current and Curie temperature(TC),and gradually drives the ferroelectric to relaxor transition.Because of the MPB with appropriate R/T phase ratio,increased grain size and density,and decreased leakage current,the well-balanced performance between d_(33)=206 pC/N and TC=488℃is obtained in x=0.01 case.In addition,the further enhanced in-situ d_(33)=286e347 pC/N is obtained in BF-BT-xBNT ceramics along with the improved depolarization temperature T_(d)from 280 to 312℃,showing a potential application for lead-free piezoceramics at high temperature.Shuai Cheng Boping Zhang Shengjie Ai Hongbao Yu Xin Wang Jiahao Yang Changrong Zhou Jingtai Zhao Guanghui Rao 2023Journal of Materiomics2023,9,3:0
9Kinetics of Nitrogen Removal from Molten Steel under Vacuum and Gas-Blowing Conditions显示文摘The kinetics of nitrogen removal from molten steel under vacuum and gas-blowing conditions has beenstudied during the VIM process. The experimental results indicated that vacuum affected the kinetics of nitrogenremoval in the range of 67-5 360 Pa. At 67 Pa, the rate of nitrogen removal is controlled by the liquid phase masstransfer of nitrogen in molten steel. At 2 680Pa, the limited step for nitrogen removal from molten steel is the chemical reaction at the metal/gas interface. Under the present experimental conditions, the type (Ar, CO, CO2) and quantity of gas flowed have no evident influences on the rate of nitrogen removal. The ratio of nitrogen removal of gasbubbles is less than 3 %. Based on the experimental results, the mechanism of nitrogen removal during the VDprocess with argon blowing and the other melting or secondary refining processes with carbon-oxygen reaction havebeen discussed. Some new viewpoints are proposed.Jie Fu Heming Chang Shixiang Zhou Boping Chen (Metallurgy Engineering School, University of Science and Technology Beijing, Beijing 100083, China) 1998International Journal of Minerals,Metallurgy and Materials1998,12,1:0
10Identification of a Novel Universal Potential Epitope on the Cytoplasmic Tail of H7N9 Virus Hemagglutinin显示文摘Dear Editor,H7N9 is a recently identified subtype of influenza A virus that caused a major outbreak in humans in China in 2013.According to the latest data provided by the Chinese Center for Disease Control and Prevention(http://gffzz2e50c3a1f8a741bahbwcbbv66kwop6n5w.ffgz.tsg.suse.edu.cn/zwgk/yqbb3/ejlist.shtml,updated on October 31,2018),the mortality rate of H7N9 infections in China amounts to 39.7%(611/1536).Thus,H7N9 poses a serious public health threat.Xi Liu Li Ding Jing Yuan Jian Liao Lian Duan Wenfei Wang Weiguo Tan Weiye Yu Boping Zhou Xinchun Chen Zheng Yang 2019Virologica Sinica2019,34,3:0
