Acquisition of a High Resolution TEM Equipped with GIF and EDS

9977391阿贾扬利用重大研究仪器基金，将获得具有纳米分析能力的最先进的全分析高分辨率电子显微镜(HRTEM)。该仪器将包括一台基本的200keV TEM机、能量色散X射线分析仪(EDS)、用于电子能量损失谱(EELS)和化学测绘的Gatan成像滤光器(GIF)和一个加热阶段。新仪器将使校园内的电子显微镜设施现代化，并将对研究能力产生重大影响。它将安置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倡议，例如关于纳米结构材料和电子互连的研究，由于校园缺乏这种现代仪器而受到影响。这种HRTEM的影响将是巨大的，因为它将使原子尺度的材料结构观察，使用EDS进行定性和定量分析，以及使用EELS进行成键状态和化学分析。材料科学与工程系、化学工程系、生物医学工程系、电气与计算机科学工程系、化学系、物理学系、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广泛的材料和结构，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-基质复合材料界面、组织-生物材料界面、蛋白质结构、玻璃和复杂矿物。此外，这一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。将进行动手培训、新显微镜的实时演示、将一些实验在线广播到教室，以及为研究生进行的HRTEM项目。作为大学本科生研究计划和RPI本科生研究体验网站的一部分，本科生将受益于这个现代化的设施。用主要研究仪器计划的资金购买一台高分辨率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。该仪器将由正在研究先进材料的七个部门的调查人员使用。学生，从博士后到本科生，将接受使用它的培训。

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.
