| 1 | Polyvinylpyrrolidone/graphene oxide thin films coated on quartz crystal microbalance electrode for NH_3 detection at room temperature显示文摘In this paper, composite film based on polyvinylpyrrolidone(PVP)/graphene oxide(GO) was fabricated by spray method on AT-cut 9.986 MHz quartz crystal microbalance(QCM) for NH_3 sensing. The thin films were characterized by scanning electron microscope(SEM), Fourier transform infrared spectroscopy(FTIR) and ultraviolet-visible spectroscopy(UV-VIS) to investigate the morphologies and the composition contents, respectively. The experimental results reveal that PVP/GO based sensor holds higher sensitivity, larger responsiveness and smaller baseline drift than those based on pure PVP at room temperature. Besides, the prepared sensor exhibits greater response to NH_3 than other gases such as CO, CO_2 and NO_2 at the same concentration. The good linearity, reproducibility and stability demonstrate the practicability of PVP/GO hybrid film in detecting NH_3. | MA XingFang XIE GuangZhong SU YuanJie DU HongFei XIE Tao JIANG YaDong | 2016 | Science China(Technological Sciences)2016，59，9： | 1 |
| 2 | Multi-Joint Active Collision Avoidance for Robot Based on Depth Visual Perception显示文摘Dear editor,Human-robot collaboration is a research topic that has numerous potential applications, such as in smart cities. An important safety consideration in human-robot collaboration is collision avoidance[1]. Many studies have prioritized collision avoidance of the robot end-effector. However, multi-joint(whole-body) collision avoidance is also very important in complex working scenarios. Several studies have achieved multi-joint collision avoidance by estimating the distance between obstacles and control points placed on the robot body. | Hui Li Xingfang Wang Xiao Huang Yifan Ma Zhihong Jiang | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，12： | 0 |
