CTS-0520863-MRI Varahramyan Louisiana Tech UniversityField Emission Scanning Electron Microscope for Nano-technology Research, Training, and Education This project provides for acquisition of a Field Emission Scanning Electron Microscope (FESEM) to enhance nano-technology research, training, and education at Louisiana Tech University (LaTech), and to allow neighboring Grambling State University (GSU) and other users in north Louisiana and the region to have access to this instrument for research, educational, and industrial needs. LaTech and GSU (HBCU) have 3 Joint Faculty Appointment Faculty (JFAP) positions associated with the Institute for Micro-manufacturing (IfM). The PI and Co-PIs of this proposal are with IfM. The PI (Varahramyan) is the IfM Director, two Co-PIs (Lvov & McShane) are IfM nano-technology leaders, one Co-PIs (Dobbins), she is a nano-technologist and a JFAP faculty directly linking the IfM and GSU nano-technology research and educational efforts, and another Co-PI (Gunasekaran) heads IfM's Measurements & Characterization Section, and has experience with wide range of instruments (including SEM) for nanoscale measurements. IfM, has existed for over 12 years, and is dedicated to micro-/nano-scale systems research, education, and commercialization. It provides its faculty and external partners/users with micro-/nano-manufacturing resources, for development of micro-/nano-systems for biomedical, chemical, information technology, and other applications. IfM, with over 30 science & engineering faculty & post-docs, and a staff of 15, consists of 65,000 sq. ft. of facilities, including a modern 41,000 sq. ft. R & D building, to house the new FESEM, in the Measurements & Characterization Section.Intellectual Merit: A wide range of research/training efforts will benefit from FESEM, including work sponsored by major NSF projects: Nano-engineered Shells for Encapsulation and Controlled Release NSF NIRT, Multilayer Modification for Micro-cantilever Biosensors NSF-ECS, and Micro/Nano-technologies Advanced Physical, Chemical, and Biological Sensors NSF/EPSCoR RII. As part of these efforts, a major area heavily relying on imaging of nano-structured materials is the development of self-assembled nano-materials for encapsulation and controlled localization of drugs, proteins, nucleic acids, and cells, for drug delivery, tissue engineering, and sensing applications. A second project recently funded by NSF is to develop extremely sensitive and highly selective micro-sensors for chemical warfare agents or simulants, by using multilayer modified micro-cantilevers. In developing these chemical sensors, the beams and nano-coatings need to be inspected with nanometer resolution. Another key focus area is biosensors and tissue engineering, which are in IfM's bioengineering area, where the techniques use a combination of micro and nano-fabrication with a biological interface of molecules that cannot be analyzed or evaluated without metrology equipment with nanometer resolution. Current IfM imaging capabilities are unable to meet the requirements of these efforts. Research needs on these and several other ongoing and new projects, including at GSU, give the basis for the FESEM request, where high resolution SEM is needed to characterize nano-scale materials and structures at 1 nm resolution, with ability to determine chemical information and spatial distributions of elements (existing SEM can not resolve features at less than ~35 nm).Broader Impact: A new FESEM coupled with existing IfM resources makes it possible for LaTech and collaborating institutions to promote nano-technology research, training, and education in a historically disadvantaged region of the nation. Planned educational efforts include teaching FESEM theory and practice in courses at LaTech (e.g. Micro/Nano Scale Materials Measurements & Analysis), attracting students from programs with nano-technology emphasis, ranging from Ph.D. in Engineering and Ph.D. in Biomedical Engineering, to MS in Molecular Science & Nano-technology and MS in Microsystems Engineering. About half of 549 (Fall 04) engineering and science M.S. and Ph.D. students are specializing in research and taking courses associated with IfM. Of 128 Ph.D. students, over half are with IfM, and their research and course work will be highly impacted by the FESEM availability. Same will be for undergraduate students, including in LaTech's new B.S. in Nano-systems Engineering (planned for Fall 05) in College of Engineering & Science, and in GSU's B.S. degrees in Physics and Chemistry, in College of Science & Technology, where Drs. Dobbins (a Co-PI) and Derosa (a Co-Investigator) are in JFAP faculty positions associated with IfM and will be leading some of these efforts. The FESEM will also serve LaTech's NSF-REU funded-project (2003-06), on "Undergraduate Experiences in Micro- & Nano-Engineering," for 10 students (including underrepresented groups) to pursue research during summer. Moreover, the FESEM will noticeably impact economic development and industrial needs of north Louisiana and the region, and will also support IfM's efforts in the NSF PFI grant (2003-06), on "Ventures for Emerging Technologies in Rural North Louisiana."

CTS-0520863-MRI Varahramyan路易斯安那理工大学用于纳米技术研究、培训和教育的场发射扫描电子显微镜该项目提供了一台场发射扫描电子显微镜，以加强路易斯安那理工大学的纳米技术研究、培训和教育，并允许邻近的格拉姆林州立大学和路易斯安那州北部和该地区的其他用户访问该仪器，以满足研究、教育和工业需求。LaTech和GSU(HBCU)有3个与微型制造研究所(IFM)相关的联合教师聘任学院(JFAP)职位。本提案的PI和Co-PI为IFM。PI(Varahramyan)是IFM主任，两个Co-PI(Lvov和Amp；McShane)是IFM纳米技术领导者，一个Co-PI(Dobbins)，她是纳米技术专家和JFAP教员，直接联系IFM和GSU纳米技术研究和教育工作，另一个Co-Pi(Gunasekaran)领导IFM的测量和放大表征科，并拥有广泛的纳米测量仪器(包括扫描电子显微镜)的经验。IFM已经存在超过12年，致力于微纳尺度系统的研究、教育和商业化。它为其教师和外部合作伙伴/用户提供微/纳米制造资源，用于开发用于生物医学、化学、信息技术和其他应用的微/纳米系统。IFM拥有30多名理工科和博士后，15名员工，占地65,000平方米。英国《金融时报》设施齐全，包括一个现代化的41,000平方米。英国《金融时报》智力优势：广泛的研究/培训工作将从FESEM中受益，包括由NSF主要项目赞助的工作：用于封装和控制释放的纳米工程壳NSF NIRT，用于微悬臂梁生物传感器的多层修饰NSF-ECS，以及微/纳米技术高级物理、化学和生物传感器NSF/EPSCoR RII。作为这些努力的一部分，严重依赖纳米结构材料成像的一个主要领域是开发自组装纳米材料，用于药物、蛋白质、核酸和细胞的封装和受控定位，用于药物输送、组织工程和传感应用。NSF最近资助的第二个项目是通过使用多层改进型微悬臂来开发用于化学战剂或模拟物的极其灵敏和高度选择性的微型传感器。在开发这些化学传感器时，需要对光束和纳米涂层进行纳米分辨率的检测。另一个关键的重点领域是生物传感器和组织工程，它们属于IFM的生物工程领域，这些技术使用微和纳米制造的组合，以及分子的生物界面，如果没有纳米分辨率的计量设备，就无法分析或评估分子。目前的IFM成像能力无法满足这些努力的要求。对这些和其他几个正在进行的和新的项目的研究需求，包括在格拉斯哥州立大学，为FESEM请求提供了基础，其中需要高分辨率的扫描电子显微镜来表征1 nm分辨率的纳米材料和结构，并能够确定化学信息和元素的空间分布(现有的扫描电子显微镜无法分辨小于~35 nm的特征)。广泛的影响：新的FESEM与现有的IFM资源相结合，使LaTech和合作机构有可能在国家历史上处于不利地位的地区促进纳米技术研究、培训和教育。计划的教育工作包括在LaTech教授FESEM理论和实践课程(例如，微/纳米尺度材料测量和分析)，吸引侧重纳米技术的项目的学生，从生物医学工程博士和博士到分子科学和纳米技术硕士以及微系统工程硕士。在549名工程和理科硕士和博士生中，约有一半的学生专门从事研究，并选修与IFM相关的课程。在128名博士生中，超过一半是IfM的学生，他们的研究和课程工作将受到FESEM可用性的高度影响。本科生也是如此，包括LaTech新的纳米系统工程学士学位(计划于2005年秋季)在工程与科学学院，以及格拉斯哥州立大学的物理与化学学士学位，在科学与技术学院，Dobbins博士(联合-PI)和DeRosa博士(联合研究员)在JFAP的教职与IFM相关，并将领导一些工作。FESEM还将为LaTech的NSF-REU资助项目(2003-06)提供服务，该项目旨在为10名学生(包括未被充分代表的群体)在暑期进行研究，主题是“微纳工程的本科生经历”。此外，FESEM将显著影响路易斯安那州北部和该地区的经济发展和工业需求，还将支持IFM在NSF PFI赠款(2003-2006年)中关于“在北路易斯安那州农村地区开展新兴技术的风险投资”的努力。
