IMR: Acquisition Of Complimentary Equipment To Enhance Student Training In Nanoscale Materials Research

材料研究仪器计划的这一奖项为位于Humacao的波多黎各大学提供资金，用于购买两台仪器，一台具有图像处理能力的高倍光学显微镜和一台半导体分析仪。这些仪器将用于纳米科学相关的研究和培训。第一个项目是使用简单的静电纺丝技术制造导电聚合物纳米纤维并对其进行电学表征。在该方法中，将溶解在适当溶剂中的聚合物置于皮下注射针中。通过向针施加高电压，聚合物溶液以射流的形式从针中挤出，并且随着溶剂蒸发，可以产生聚合物的超细纤维。第二个项目是使用化学气相沉积（CVD）技术制造碳纳米管。纳米纤维和纳米管将以场效应晶体管配置电连接。其目的是能够制造电子设备。光学显微镜将用于选择良好的样品进行表征，并研究聚合物纳米纤维中的电致变色效应，同时有外部电流流过纤维。电致变色效应的散装导电聚合物已经完成了在过去，但没有在纳米纤维。这些仪器也将在高级实验室用于与纳米技术相关的专业实验。这些仪器是多用户型的，将加强与物理和电子系以及生物系的研究合作。此次收购将加强该大学的物理和电子本科课程以及该岛东南部的研究和教育计划。该奖项来自材料研究计划仪器，支持位于Humacao的波多黎各大学，收购具有图像处理能力的高倍光学显微镜和半导体分析仪。这些仪器将用于纳米科学相关的研究和培训。第一个项目是导电聚合物纳米纤维的制造和电特性。 第二个项目是使用化学气相沉积（CVD）技术制造碳纳米管。其目的是能够制造电子设备。光学显微镜将用于选择良好的样品进行表征，并研究电流流过纤维的聚合物纳米纤维中的电致变色效应。电致变色效应的散装导电聚合物已经完成了在过去，但没有在纳米纤维。这些仪器也将在高级实验室用于与纳米技术相关的专业实验。这些仪器将加强与物理和电子系以及生物系的研究合作。此次收购将加强该大学的物理和电子本科课程以及该岛东南部的研究和教育计划

This award from the Instrumentation for Materials Research program provides funds to the University of Puerto Rico at Humacao, to purchase two instruments, a high power optical microscope with image processing capability and a semiconductor analyzer. The instruments will be used in nanoscience related research and training. The first project is the fabrication and electrical characterization of conducting polymer nanofibers using a simple electrospinning technique. In this method, the polymer dissolved in an appropriate solvent is placed in a hypodermic needle. By applying a high voltage to the needle, the polymer solution is forced out from the needle in the form of a jet, and as the solvent evaporates, ultra fine fibers of the polymer can be generated. The second project is the fabrication of carbon nanotubes using chemical vapor deposition (CVD) techniques. The nanofibers and nanotubes will be electrically connected in a field effect transistor configuration. The purpose is to be able to fabricate electronic devices. The optical microscope will be used in selecting good samples for characterization and to study electro chromic effects in the polymer nanofibers in-situ while there is an external current flowing through the fiber. Electro chromic effects on bulk conducting polymers have been done in the past but not in nanofibers. The instruments will also be used in Senior Lab for specialized experiments related to nanotechnology. The instruments are of the multi-user type and will enhance research collaboration with the Department of Physics and Electronics and the Biology Department. The acquisition will strengthen the undergraduate program in Physics and Electronics at the University and the research and education program in the Southeast part of the island This award from the Instrumentation for Materials Research program supports the University of Puerto Rico at Humacao, with the acquisition a high power optical microscope with image processing capability and a semiconductor analyzer.
