Funds from this Major Research Instrumentation (MRI) Program grant will support the purchase of a new field emission scanning electron microscope (FE-SEM) for the Imaging and Histology Core Facility (IHCF) at Northern Arizona University (NAU). This instrument will include a thermal field emission (FE) electron source, secondary electron imaging (SEI), backscatter electron imaging (BSE), electron backscattered diffraction (EBSD), wavelength disperse detector (WDS), scanning transmission electron microscopy (STEM), variable vacuum (VP), an interactive software system for live export of information to other locations (including across campus and to collaborators at other institutions), image archiving with database management, and collaborative software. This FE-SEM will support research and training across a number of departments at NAU including Chemistry & Biochemistry, Forestry, Mechanical Engineering, Biological Sciences, Environmental Sciences, and Physics & Astronomy. Ongoing research that will be supported by this instrument includes (1) properties of uranium oxide particulates and their uptake and localization in living cells; (2) changes occurring in pinyon pine (Pinus edulis) during severe drought; (3) accumulation of uranium is tissues of mice exposed to environmentally contaminated drinking water; (4) investigation of the role of giant titin protein in active muscle of mice; (5) symbiotic interactions among plant roots, fungi, and bacteria; (6) characterization of existing and novel biomaterials used for vascular grafts with human elastin; and (7) characterization of nanoparticle thin films used for energy storage. Acquisition of a new FE-SEM will strengthen NAU's ongoing efforts in basic research, training of underrepresented students, business development, and collaborative work with academic institutions in Arizona and beyond. This instrument will improve the quality of research at NAU in the four areas of research targeted by our current Strategic Plan for Enhancing Research and Scholarship at NAU, namely life sciences/biosciences, renewable energy, landscape conservation/geospatial technologies, and climate-ecosystem interactions. It will significantly enhance the hands-on training of our undergraduate and graduate students in STEM fields, including women, Native American and Hispanic students. It will strengthen the many community outreach programs currently conducted or facilitated by the IHCF, and will foster connections between NAU and regional businesses.

这项主要研究工具（MRI）计划赠款的资金将支持购买北亚利桑那大学（NAU）的成像和组织学核心设施（IHCF）的新现场排放扫描电子显微镜（FE-SEM）。该仪器将包括热场发射（FE）电子源，次级电子成像（SEI），反向散射电子成像（BSE），电子反向散射衍射（EBSD），波长分散检测器（WDS），扫描透射式电子显微镜（STEM），与其他可变真空（vp）相互作用（vp）的启动（VP）（vp）（vp）（vp）（vp）（VP机构），具有数据库管理的图像归档和协作软件。 该FE-SEM将支持NAU多个部门的研究和培训，包括化学和生物化学，林业，机械工程，生物科学，环境科学以及物理与天文学。 该仪器将支持的正在进行的研究包括（1）氧化铀颗粒的特性及其在活细胞中的摄取和定位； （2）在严重干旱期间菠萝松树（Pinus edulis）发生变化； （3）铀的积累是暴露于受环境污染的饮用水的小鼠的组织； （4）研究巨型钛蛋白在小鼠活性肌肉中的作用； （5）植物根，真菌和细菌之间的共生相互作用； （6）用于具有人类弹性蛋白的血管移植物的现有和新型生物材料的表征； （7）用于储能的纳米颗粒薄膜的表征。 收购新的FE-SEM将加强NAU在基础研究，对代表性不足的学生，业务发展培训，业务发展以及与亚利桑那州及其他地区学术机构的合作工作的培训。 该工具将在我们当前的战略计划针对NAU的四个研究领域中提高NAU的研究质量，即增强NAU的研究和奖学金，即生命科学/生物科学，可再生能源，景观保护/地理空间技术以及气候生态系统的相互作用。 它将显着增强我们在STEM领域的本科和研究生的动手培训，包括女性，美洲原住民和西班牙裔学生。 它将加强IHCF目前执行或促进的许多社区外展计划，并将建立NAU与区域企业之间的联系。
