The College of Natural Resources and Sciences Core Facility at Humboldt State University is a recently established shared-use laboratory for student and faculty research. This award will allow the addition of a modern environmental scanning electron microscope (ESEM) with back-scattered electron (BSE) imaging and energy dispersive x-ray spectrometry (EDS) and supporting sample preparation equipment to the facility, greatly increasing the range of studies that can be undertaken. Planned research activities in the biological sciences include investigations of the olfactory epithelium of amphibians, plant gravitropism, bryozoan phylogeny, bee genitalia, fungal systematics, the neurobiology and ecotoxicology of freshwater worms, the stomatal features of the world?s tallest trees, developmental defects associated with sperm protein knockdown in C. elegans, and bacterial interactions with mineral particles in acid lakes at Lassen Volcanic National Park. In the earth sciences, studies will include analyses of high-temperature, high-pressure mineralogy and petrology experiments, the microstructures and rock textures formed in active fault zones, the weathering properties of minerals and formation of soils, and the microstructure of fossil plants. In the physical sciences, studies on the surface properties of test masses will allow precise testing of the gravitational inverse-square law. Humboldt State currently has no ESEM or EDS capabilities, and is located in a rural area of northern California, far from other universities and comparable instrumentation. The addition of an ESEM will allow researchers and students interested in examination of fresh (hydrated) biological specimens, and advanced elemental, textural, and material analysis to conduct cutting-edge research.The new CNRS Core Facility represents the first major endeavor on the HSU campus to create a true interdisciplinary, shared-use facility in the sciences. The ESEM will serve as a keystone addition to the facility by bringing together researchers from departments across the college. The instrument will enhance the experience of students in the Electron Microscopy course, as well as in mineralogy, petrology, and structural geology courses. Because the new instrument can be operated remotely, it will also facilitate outreach activities to the local community that are not currently possible. In particular, a permanent exhibit on microscopic natural history will be established at the HSU Natural History Museum, and live remote operations will be conducted there at yearly events. Training institutes for secondary science teachers over the summer will be followed in the fall by the opportunity for the teachers to remotely operate the instrument to examine specimens that their students have collected, providing a unique opportunity to high schools throughout rural northern California.

洪堡州立大学自然资源与科学学院核心设施是最近成立的一个供学生和教师研究的共享实验室。该奖项将允许在该设施中增加一台具有背散射电子 (BSE) 成像和能量色散 X 射线光谱 (EDS) 功能的现代环境扫描电子显微镜 (ESEM) 以及配套的样品制备设备，从而极大地扩大了可进行的研究范围。生物科学方面计划的研究活动包括研究两栖动物的嗅觉上皮、植物向地性、苔藓虫系统发育、蜜蜂生殖器、真菌系统学、淡水蠕虫的神经生物学和生态毒理学、世界上最高的树木的气孔特征、与秀丽隐杆线虫精子蛋白敲低相关的发育缺陷以及与细菌的相互作用。 拉森火山国家公园酸性湖中的矿物质颗粒。 在地球科学方面，研究将包括高温高压矿物学和岩石学实验的分析，活动断裂带形成的微观结构和岩石结构，矿物的风化特性和土壤的形成，以及化石植物的微观结构。 在物理科学中，对测试质量的表面特性的研究将允许精确测试引力平方反比定律。洪堡州立大学目前没有 ESEM 或 EDS 能力，并且位于加利福尼亚州北部的农村地区，远离其他大学和类似的仪器。 ESEM 的增加将使对新鲜（水合）生物样本检查以及先进的元素、结构和材料分析感兴趣的研究人员和学生能够进行前沿研究。新的 CNRS 核心设施代表了 HSU 校园为创建真正的跨学科、共享的科学设施而做出的第一项重大努力。 ESEM 将汇集学院各部门的研究人员，作为该设施的重要补充。该仪器将增强学生在电子显微镜课程以及矿物学、岩石学和构造地质学课程中的体验。 由于新仪器可以远程操作，因此它还将促进目前无法进行的当地社区外展活动。 特别是，恒生州立大学自然历史博物馆将设立一个关于微观自然历史的永久展览，并在每年的活动中进行现场远程操作。 夏季为中学科学教师提供培训的机构将于秋季推出，教师将有机会远程操作仪器来检查学生收集的标本，这为整个北加州农村地区的高中提供了独特的机会。
