Intrinsic carrier transport properties of single-walled carbon nanotubes have been probed by two parallel methods on the same individual tubes： The contactless dielectric force microscopy （DFM） technique and the conventional field-effect transistor （FET） method. The dielectric responses of SWNTs are strongly correlated with electronic transport of the corresponding FETs. The DC bias voltage in DFM plays a role analogous to the gate voltage in FET. A microscopic model based on the general continuity equation and numerical simulation is built to reveal the link between intrinsic properties such as carrier concentration and mobility and the macroscopic observable, i.e. dielectric responses, in DFM experiments. Local transport barriers in nanotubes, which influence the device transport behaviors, are also detected with nanometer scale resolution.

Introduction. A series Of Mo-Fe-S complexes with doublecubane structure has been synthesized and identified. Because of the similarity of its extended X-ray absorption fine structure (EXAFS) to that of FeMo cofactor and nitrogenase, suggestion has been made that the doublecubane complexes may serve as models for the Mo site of nitrogenase. Therefore, the investigation of this type of complexes has attracted much attention. By using the similar method of spontaeous self-assembly reaction, and starting from certain kinds of Mo-Fe-S compounds, we have been able to obtain several kinds of compounds, one of which

从本质上看,数字教材是纸质教材的创新与优化,和纸质教材同样承载着课程标准与教学内容传递的功能,但同时促进了教学资源的延伸和教学模式的转变。教育行政部门应当在数字教材建设中发挥主导作用,履行审查教材内容、确保教材内容与教学数据安全以及保障利益主体合作共赢的职责。当前,数字教材建设存在教育行政部门缺位、市场主体合力缺乏、安全机制不健全等问题,制约了数字教材建设及教学应用的深入开展。未来应当加强政策顶层设计,强化政府在数字教材建设的主导作用;建立分级审查机制,确保数字教材资源的开放与共享;建立统一管理平台,优化数字教材建设与应用流程;优化教育治理体系,保障利益相关主体合作共赢。
