With this award from the Chemistry Major Research Instrumentation (MRI) Program that is cofunded by the Chemistry Research Instrumentation Program, Professor Chaoyang Jiang from University of South Dakota and colleagues Dongming Mei, Paul May and Ranjit Koodali will acquire a high-resolution field emission scanning electron microscope (FE-SEM) with an energy-dispersive X-ray spectroscopy (EDS) attachment for elemental analysis and mapping. The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) plasmonic enhancement of near-infrared-to-visible luminescence; (b) thin films by laser assisted chemical vapor deposition; (c) cubic mesoporous materials with varied morphologies; (d) cuprous oxide nanoparticles; (e) fluorinated polymeric materials for air-stable and moisture-resistant flexible optoelectronics; (f) metal-semiconductor hybrid nanocrystals for solar fuels catalysis; (g) dissociation density characterization and wafer processing of ultrapure germanium single crystals; (h) research on the pigments in paintings on historical music instruments; and (i) materials characterization for earth science research.A scanning electron microscope (SEM) is one of the basic tools available for the characterization of materials. A beam of electrons scans the surface of a sample resulting in a microimage of the sample composition. The electron microscope can provide higher resolution and magnification than a microscope using light to probe the material. Characteristic X-rays are produced from interaction with atoms in the sample that when dispersed provide information on the elemental composition (EDS). This instrumentation will provide microscopy training and research opportunities to graduate and undergraduate students across many fields including chemistry, earth sciences and environmental science fields preparing them for the demands of the 21st century workforce in science and technology. The instrumentation will impact research and research training of researchers and students not only at the University of South Dakota but also at neighboring institutions and tribal colleges such as Barrett Eichler, Augustana College; Carl Fictorie, Dordt College (Sioux City, Iowa); and Subodh Singh and Sinte Gleska University.

通过化学研究仪器（MRI）计划的奖项，该计划由化学研究仪器计划获得了奖励，南达科他大学的Chaoyang Jiang教授和同事Dongming Mei，Paul May和Ranjit Koodali将获得高分辨率扫描电子显微镜（Fe-ed-Eds）的高分辨率（Fe-Semist）（Fe-Semants）和映射。该提案旨在增强各个级别的研究和教育，尤其是在（a）等离子体增强近红外发光的领域； （b）激光辅助化学蒸气沉积的薄膜； （c）具有多种形态的立方介孔材料； （d）氧化物纳米颗粒； （e）氟化的聚合物材料，用于空气稳定和耐水性柔性光电子； （f）用于太阳能燃料催化的金属 - 气门杂交纳米晶体； （g）超纯锗单晶的解离密度表征和晶圆处理； （h）研究历史乐器绘画中的颜料； （i）地球科学研究的材料表征。扫描电子显微镜（SEM）是可用于表征材料的基本工具之一。一束电子扫描样品表面，导致样品组成的显微图像。与使用光探测材料的显微镜相比，电子显微镜可以提供更高的分辨率和放大倍数。特征性X射线是由与样品中与原子的相互作用产生的，当分散时提供有关元素组成的信息（EDS）。该仪器将提供显微镜培训和研究机会，为许多领域的研究生毕业和本科生，包括化学，地球科学和环境科学领域，为21世纪劳动力在科学技术方面的需求做准备。该仪器将不仅会影响南达科他大学的研究人员和学生的研究培训，还会影响邻近的机构和部落学院，例如奥古斯塔纳学院（Augustana College），例如Barrett Eichler；多德学院（爱荷华州苏城）的卡尔·菲克里（Carl Fictorie）；以及Subodh Singh和Sinte Gleska大学。
