Preparation of organic thin-film field effect transistor

The organic thin-film field effect transistor was prepared through vacuum deposition by using teflon as di-electric material. Indium-tin-oxide acted as the source and drain electrodes. Copper phthalocyanine and teflon were used as the semiconductor layer and dielectric layer, respectively. The gate electrode was made of Ag. The channel length between the source and drain was 50 μm. After preparing the source and drain electrodes by lithography, the copper phthalocyanine layer, teflon layer and Ag layerwere prepared by vacuum deposition sequentially. The field effect electron mobility of the device reached 1.1×10ˉ6 cm2/(V@s), and the on/off current ratio reached 500.

水稻花粉悬浮培养及其在育种上的应用

评估了２０个水稻品种离体花粉悬浮培养产生愈伤组织和再分化植株的能力，并进行了花粉悬浮培养试验，结果表明；品种之间反应差异很大。来源于日本的“黎明”（粳稻）最敏感。“黎明”植株再分化的频率达８４．１％。在愈伤组织的形成和植株再分化过程中，除其它一些因子外，基因型的差异有一定制约作用。通过水稻花粉悬浮培养诱导出的新品系“Ｎ１０”，其特征有：早熟，穗大，株高（９０～１００ｃｍ），产量高和抗稻瘟病等。

管流与环缝入流的管内合流特性──等温浓度场与紊流特性实验研究

在对管流与环缝入流的管内合流特性完成等温速度场实验研究的基础上，以对应一致的实验条件，实测了时均浓度分布，紊流正应力和紊流切应力分布．结果证明：浓度分布有与速度分布相一致的变化趋势和规律，但合流后截面上浓度均匀化比速度均匀化慢；合流动量相交产生附加雷诺应力，并决定合流后速度分布和浓度分布的均匀化进程．为建立系统的化学反应流动规律提供基础．

Earthshaker: A mobile rescue robot for emergencies and disasters through teleoperation and autonomous navigation

To deal with emergencies and disasters without rescue workers being exposed to dangerous environments, this paper presents a mobile rescue robot, Earthshaker. As a combination of a tracked chassis and a six-degree-of-freedom robotic arm, as well as miscellaneous sensors and controllers, Earthshaker is capable of traversing diverse terrains and fulfilling dexterous manipulation. Specifically, Earthshaker has a unique swing arm—dozer blade structure that can help clear up cumbersome obstacles and stabilize the robot on stairs, a multimodal teleoperation system that can adapt to different transmission conditions, a depth camera-aided robotic arm and gripper that can realize semiautonomous manipulation and a LiDAR aided base that can achieve autonomous navigation in unknown areas. It was these special systems that supported Earthshaker to win the first Advanced Technology & Engineering Challenge (A-TEC) championships, standing out of 40 robots from the world and showing the efficacy of system integration and the advanced control philosophy behind it.
