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.

洪堡州立大学的自然资源与科学学院核心设施是一个最近建立的供学生和教师研究的共享实验室。该合同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射线光谱仪（EDS）的现代环境扫描电子显微镜（ESEM）以及支持样品制备设备，从而大大增加了可以进行的研究范围。计划在生物科学方面开展的研究活动包括：两栖动物的嗅上皮、植物向地性、苔藓虫的生殖器发生、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、世界的气孔特征？的最高的树木，发育缺陷与精子蛋白敲低在C。以及拉森火山国家公园酸性湖泊中细菌与矿物颗粒的相互作用。 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分析、活动断层带形成的显微结构和岩石结构、矿物的风化特性和土壤的形成以及化石植物的显微结构。 在物理科学中，对测试质量的表面性质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环境扫描电镜或EDS能力，位于北方加州的农村地区，远离其他大学和可比仪器。环境扫描电镜的增加将使研究人员和学生有兴趣检查新鲜（水合）生物标本，先进的元素，纹理和材料分析进行尖端研究。新的CNRS核心设施代表了HSU校园的第一个重大奋进，创造一个真正的跨学科，共享使用的设施在科学。 ESEM将作为该设施的基石，将学院各部门的研究人员聚集在一起。该仪器将增强学生在电子显微镜课程，以及矿物学，岩石学和结构地质学课程的经验。 由于新仪器可以远程操作，它还将促进目前不可能开展的面向当地社区的外联活动。 特别是，将在HSU自然历史博物馆建立一个关于微观自然历史的永久展览，并在年度活动中进行现场远程操作。 夏季的中学科学教师培训机构将在秋季为教师提供远程操作仪器检查学生收集的标本的机会，为整个北方加州农村的高中提供独特的机会。
