Acquisition of a Transmission Electron Microscope for Nano/Biomaterials Research and Education

摘要提案标题：MRI：获得用于纳米/生物材料研究和教育的透射电子显微镜提案编号：cts -0619440-MRI首席研究员：Arijit BoseInstitution：罗德岛大学该奖项将获得罗德岛大学（URI）用于无机，有机和生物纳米材料研究和教育的扫描/透射电子显微镜（S/TEM）。S/TEM系统将用于开展广泛的创新研究项目，包括检查表面活性剂在高度受限域中的微观结构演变，这对药物输送和表面活性剂介导的采油作业都很有用。它将用于表征纳米颗粒/聚合物复合材料在极端或冲击载荷条件下的断裂。该仪器将用于研究海洋浮游植物的生物多样性和进化生态学，并了解纳米颗粒的毒理学影响。来自工业界的同事和来自不同院系以及其他大学的大约六名其他URI教员也将在他们的研究主题中广泛使用这种新仪器，从表面活性剂微观结构的光诱导变化到磁性纳米颗粒表面弛豫的测量。S/TEM仪器，以及改进的冷冻样品制备和成像能力，将对罗德岛大学和地区大学的研究和教育产生重大影响，并将改善与工业界的合作，并为当地高中提供重要的新扩展能力。拟议的工具将大大改善URI的研究和教育基础设施。远程控制显微镜的能力将允许高中生通过互联网操作S/TEM，为他们提供独特的实践经验，在最先进的仪器上。地方和国家工业也将使用显微镜，使合作远远超出大学范围。从URI的LSAMP计划开始，这次收购将通过接触最先进的技术，在鼓励科学和工程领域中代表性不足的群体参与方面发挥重要作用。此外，这次收购将有助于吸引高素质的教师和学生到URI。广泛的研究人员使用它将促进跨学科和机构间研究的协同气氛。

AbstractProposal Title: MRI: Acquisition of a Transmission Electron Microscope for Nano/Biomaterials Research and EducationProposal Number: CTS-0619440-MRIPrincipal Investigator: Arijit BoseInstitution: University of Rhode IslandThis award will acquire a Scanning/Transmission Electron Microscope (S/TEM) for research and education spanning inorganic, organic and biological nanomaterials at the University of Rhode Island (URI). The S/TEM system will be used to carry out a wide range of innovative research projects including the examination of surfactant microstructure evolution in highly constrained domains, which is useful for drug delivery as well as surfactant-mediated oil recovery operations. It will be employed for the characterization of fracture in nanoparticle/polymer composite materials especially under extreme or impact loading conditions. The instrument will be used to study marine phytoplankton biodiversity and evolutionary ecology and to understand the toxicological impact of nanoparticles. Colleagues from industry and about a half-dozen other URI faculty from various departments as well as other universities will also extensively use this new instrument in their research in topics ranging from light-induced changes in surfactant microstructures to measurement of surface relaxation in magnetic nanoparticles. The S/TEM instrument, along with improved cryo- sample preparation and imaging capability, will have a significant impact on research and education at the University of Rhode Island, regional universities and will improve collaborations with industry and provide significant new outreach capabilities to local high schools. The proposed instrument will greatly improve the infrastructure for research and education at URI. The ability to control the microscope remotely will allow high school students to operate the S/TEM through the internet, providing them with unique hands-on experience on a state-of-the-art instrument. Local as well as national industries will also use the microscope, allowing collaborations to extend well beyond the university. Beginning with the LSAMP program at URI, this acquisition will play an important role in encouraging the participation of underrepresented groups in the areas of science and engineering through exposure to state-of-the-art technology. In addition, this acquisition will help to attract high-quality faculty and students to URI. Its use by a wide range of investigators will promote a synergistic climate of cross-disciplinary and inter-institutional research.
