This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program Professor Bruce A. Parkinson and colleagues Carrick M. Eggleston, Susan M. Swapp and Jinke Tang from the University of Wyoming will acquire a field emission scanning electron microscope (FESEM) with energy dispersive spectrometry (EDS), e-beam lithography, electron beam induced current (EBIC), scanning transmission electron (STEM), and a low-voltage, high-contrast detector. The award is aimed at enhancing research training and educations at all levels especially research ranging from microbiological interaction with minerals to nanocomposite or nanoparticles alloys, solar energy research involving nanostructured films of photocatalytic oxides and photovoltaic materials, nanoparticle energy storage and conversion materials as well as research on microbial and biofuel cells.Scanning electron microscopy (SEM) is a widely used technique for providing images of surfaces. The FESEM is equipped with a cathode in the electron gun. The images are obtained from scanning the surface with a beam of electrons that are accelerated under the influence of a strong electrical (field) voltage. This important technique enables scientists to see the ultrastructural details of fabricated systems, molecular arrangements of man-made nanostructures and the subtle changes associated with friction and wear in surfaces. The studies described here will impact a number of areas, including chemistry, materials chemistry, geology, biochemistry and the environment. This instrument will be an integral part of teaching as well as research.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。帕金森和他的同事卡里克M.放大图片作者：埃格莱斯顿.来自怀俄明州大学的Swapp和Jinke Tang将获得一台场发射扫描电子显微镜（FESEM），该显微镜具有能量色散谱仪（EDS）、电子束光刻、电子束感应电流（EBIC）、扫描透射电子（STEM）和低压高对比度探测器。该奖项旨在加强各级研究培训和教育，特别是从微生物与矿物的相互作用到纳米复合材料或纳米颗粒合金，涉及光催化氧化物和光伏材料纳米结构薄膜的太阳能研究，纳米颗粒储能和转换材料以及微生物和生物燃料电池的研究。扫描电子显微镜（SEM）是用于提供表面图像的广泛使用的技术。FESEM在电子枪中配备有阴极。这些图像是通过用电子束扫描表面获得的，电子束在强电场电压的影响下被加速。这项重要的技术使科学家能够看到制造系统的超微结构细节，人造纳米结构的分子排列以及与表面摩擦和磨损相关的细微变化。这里描述的研究将影响许多领域，包括化学，材料化学，地质学，生物化学和环境。该仪器将成为教学和研究的一个组成部分。
