9977391AjayanUsing Major Research Instrumentation funds, a state-of-the-art complete analytical high resolution transmission electron microscope (HRTEM) with nano-analytical capabilities will be acquired. The instrument will include a basic 200 keV TEM machine, energy dispersive X-ray analyzer (EDS), Gatan Imaging Filter (GIF) for electron energy loss spectroscopy (EELS) and chemical mapping and a heating stage. The new instrument will modernize the electron microscopy facility on campus and will have a large impact on the research capabilities. It will be housed in the Materials Research Center of Rensselaer Polytechnic Institute. There are new strategic research and academic initiatives, for example on nanostructured materials and electronic interconnects, that suffer from the lack of such modern instrumentation on campus. The impact of this HRTEM will be tremendous as it will allow the atomic scale observation of material structures, qualitative and quantitative analysis using EDS, and the bonding state and chemical analysis using EELS. Faculty from the Departments of Materials Science and Engineering, Chemical Engineering, Bio-medical Engineering, Electrical and Computer Science Engineering, Chemistry, Physics and Earth and Environmental Sciences will use this instrument in their research projects to examine a wide range of materials and structures that include carbon nanotubes, nanocomposites, metal and ceramic nanostructures, semiconductor materials and thin films, electrodeposited coatings, fiber-matrix composite interfaces, tissue-biomaterial interfaces, protein structures, glasses and complex minerals. In addition, this instrument will have a significant impact on graduate and undergraduate training and course development. Hands on training, real-time demonstrations on the new microscope, on-line broadcasting of some of the experiments to class-rooms, and HRTEM projects for graduate students will take place. Undergraduate students who are part of the university undergraduate research program and the Research Experiences for Undergraduates site at RPI will benefit from this modern facility. Acquisition of a high resolution transmission electron microscope with funds from the Major Research Instrumentation program will have a large impact on the research and training infrastructure at Rensselaer Polytechnic Institute. This instrument will be used by investigators in seven departments that are working on advanced materials. Students, ranging from post doctoral to undergraduates, will be trained in its use.

9977391Ajayan 利用主要研究仪器资金，将购买一台具有纳米分析能力的最先进的完整分析高分辨率透射电子显微镜（HRTEM）。 该仪器将包括基本的 200 keV TEM 机器、能量色散 X 射线分析仪 (EDS)、用于电子能量损失光谱 (EELS) 和化学测绘的 Gatan 成像滤波器 (GIF) 以及加热台。 新仪器将使校园的电子显微镜设施现代化，并对研究能力产生重大影响。它将坐落在伦斯勒理工学院材料研究中心。 有一些新的战略研究和学术举措，例如纳米结构材料和电子互连方面的研究和学术举措，由于校园内缺乏此类现代仪器而受到影响。 HRTEM 的影响将是巨大的，因为它将允许对材料结构进行原子尺度观察，使用 EDS 进行定性和定量分析，以及使用 EELS 进行键合状态和化学分析。 材料科学与工程、化学工程、生物医学工程、电气与计算机科学工程、化学、物理以及地球与环境科学系的教师将在他们的研究项目中使用该仪器来检查各种材料和结构，包括碳纳米管、纳米复合材料、金属和陶瓷纳米结构、半导体材料和薄膜、电沉积涂层、纤维基体 复合材料界面、组织-生物材料界面、蛋白质结构、玻璃和复杂矿物质。 此外，该工具将对研究生和本科生的培训和课程开发产生重大影响。 实践培训、新型显微镜的实时演示、一些实验的在线广播以及研究生的 HRTEM 项目都将进行。 参与大学本科研究项目和 RPI 本科生研究体验网站的本科生将受益于这一现代化设施。利用重大研究仪器计划的资金购买高分辨率透射电子显微镜将对伦斯勒理工学院的研究和培训基础设施产生重大影响。 该仪器将供七个研究先进材料的部门的研究人员使用。 从博士后到本科生的学生都将接受其使用培训。
