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

该奖项来自材料研究仪器项目，为波多黎各大学胡马考分校提供资金，用于购买两台仪器，一台具有图像处理能力的高功率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备导电聚合物纳米纤维并进行电学表征。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。通过对针头施加高压，聚合物溶液以射流的形式从针头中挤出，随着溶剂的蒸发，聚合物的超细纤维可以生成。第二个项目是利用化学气相沉积（CVD）技术制造碳纳米管。纳米纤维和纳米管将在场效应晶体管结构中电连接。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，并在有外部电流流过聚合物纳米纤维时原位研究其电致变色效应。电致变色效应在块状导电聚合物上已有研究，但在纳米纤维上还没有。这些仪器还将用于高级实验室进行与纳米技术有关的专门实验。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仪器项目，支持波多黎各大学胡马考分校，获得了具有图像处理能力的高功率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备和电学表征。第二个项目是利用化学气相沉积（CVD）技术制造碳纳米管。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，也将用于研究电流流过聚合物纳米纤维时的电致变色效应。电致变色效应在块状导电聚合物上已有研究，但在纳米纤维上还没有。这些仪器还将用于高级实验室进行与纳米技术有关的专门实验。这些仪器将加强与物理及电子系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课程

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.
