MRI: Acquisition of Transmission Electron Microscope Digital Camera

该奖项由主要研究仪器和化学研究仪器计划以及刺激竞争性研究的既定计划（EPSCoR）支持。南达科他州大学正在购买一台用于透射电子显微镜（TEM）的数码相机，以支持James Hoefelmeyer教授及其同事Ranjit Koodali，Chaoyang Jiang，Grigoriy Sereda和Aravind Baride。一般来说，TEM发送电子束穿过一层薄材料。电子束与物质相互作用产生视觉图像，类似于显微镜。这些图像由相机记录，对于研究材料的化学性质非常重要。这些图像揭示了结构的细节，例如纳米颗粒或蛋白质的大小和形状。这些信息有助于研究人员了解材料的特性并加以改进。这一收购加强了本科生在研究方面的培训。该仪器是该机构和附近大学（如南达科他州州立大学、内布拉斯加州印第安社区学院（NICC，位于南苏城、梅西和桑蒂，NE）和红云印第安学校）的本科生和研究生的教学、研究和研究培训的一个组成部分。该奖项显著提高了功能，并赋予了大量使用的透射电子显微镜新的生命。该奖项旨在加强各级的研究和教育。它特别影响研究控制和表征等离子体纳米材料的表面增强拉曼散射和防伪应用。该仪器还用于研究使用纳米多孔碳材料的水污染物的光催化降解，并研究用于防伪应用的镧系元素掺杂的NaYF4（四氟化钇钠）上转换纳米晶体。此外，它还为探索太阳能燃料催化、燃料电池和锂离子电池的使用提供了信息。该仪器还用于鉴定由石墨烯功能化多层微粒制备的抗菌涂层。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs as well as the Established Program to Stimulate Competitive Research (EPSCoR). The University of South Dakota is acquiring a digital camera for a transmission electron microscope (TEM) to support Professor James Hoefelmeyer and colleagues Ranjit Koodali, Chaoyang Jiang, Grigoriy Sereda and Aravind Baride. In general, a TEM sends a beam of electrons through a thin layer of material. The electron beam interacts with the substance to produce a visual image, similar to a microscope. The images are recorded by a camera and they are important for research on the chemical properties of materials. The images reveal details of the structure, such as size and shape of a nanoparticle or a protein. This information helps researchers understand the material's properties and improve them. The acquisition enhances the training of undergraduates in research. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students at this institution and nearby universities such as South Dakota State University, Nebraska Indian Community College (NICC, in South Sioux City, Macy and Santee, NE) and Red Cloud Indian School.The award significantly increases the capabilities and gives a new life to a heavily used transmission electron microscope. The award is aimed at enhancing research and education at all levels. It especially impacts studies controlling and characterizing plasmonic nanomaterials for surface enhanced Raman scattering and anti-counterfeiting applications. The instrumentation is also used for studying photocatalytic degradation of aqueous pollutants using nanoporous carbon materials and investigating lanthanide-doped NaYF4 (sodium ytrium tetrafluoride) upconversion nanocrystals for anti-counterfeiting applications. In addition, it provides information for exploring the use of solar fuels catalysis, fuel cells, and lithium ion batteries. The instrumentation is also used to identify antimicrobial coatings prepared by functionalized multilayered microparticles of graphene.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
