FERROELECTRIC CHARACTERISTICS OF SrBi2Ta2O9 THIN FILMS ANNEALED IN FORMING GAS A.D.Li1,N.B.Ming1,D.S.Wang2,Z.G.Liu1,D.Wu1,T.Yu2,A.Hu2 (1.Department of Material Science and Engineering & National..., China) Abstract:The degradation behavior of SrBi2 Ta2O9 (SBT) thin filras annealed in forming gas (5%H2+95%N2) was investigated. The ferroelectric remnant polarization Pr of SBT had a severe decrease......
130012, China) Abstract: To solve the trajectory tracking problem of reconfigurable manipulator with sensor faults and actuator faults,a decentralized active fault-tolerant control method based on sliding mode observer was investigated.The sensor faults were equated to the actuator faults by introducing a new state.Based on these works, a sliding mode observer aiming at the new system which nonlinear......
is shown in Fig. 1. Fig. 1 Structure illustration of side-heating gas sensor Fig. 2 SEM images of ZnO nanorods annealed at different temperatures Afterwards, the gained sensor was dried at 100 °C..., the gas sensing of ZnO nanomaterials sensor to different gases was carried out and the data of gas sensitivity were recorded by a Labview recording system. The relative response sensitivity (S......
sensing analysis system. The fabrication and testing procedure of gas sensor are similar to that described in Ref. [21]. Firstly, the as-prepared samples were dispersed in deionized water to form... Co., Ltd., China). The gas sensitivity (S) was defined as S=Ra/Rg, where Raand Rg are sensor resistances in the air and target gas, respectively. 3 Results and discussion The XRD patterns of the Ce......
