This award provides support for purchase an environmental scanning electron microscope (ESEM) to be used for examining fully hydrated specimens, a use not possible with a conventional scanning electron microscope (SEM). The ESEM is fully capable of handling observation of wet, dirty, uncoated, even living specimens, as well as observation of dynamic biological processes. The ability of the ESEM to maintain the hydration of a sample indefinitely allows the examination of biological and other wet samples in their natural state. Initial uses for the instrument include studies in botanical and fungal sytematics, tracking of neural crest cell migration and other developmental processes, including imaginal disk folding, and examination of unprocessed or immunolabelled tissue samples. In addition to its use in research, the instrument will be used in training of undergraduate and graduate students and as part of training activities involving high school teachers.

该合同为购买环境扫描电子显微镜(ESEM)提供支持，用于检查完全水合的样品，这是传统扫描电子显微镜(SEM)不可能实现的用途。环境扫描电子显微镜完全有能力观察湿的、脏的、没有涂层的、甚至是活的标本，以及动态生物过程的观察。环境扫描电子显微镜能够无限期地保持样品的水合状态，从而可以检查处于自然状态的生物样品和其他潮湿样品。该仪器最初的用途包括研究植物学和真菌系统学，跟踪神经脊细胞迁移和其他发育过程，包括想象中的盘折叠，以及检查未经处理或免疫标记的组织样本。除了在研究中使用外，该仪器还将用于本科生和研究生的培训，并作为高中教师培训活动的一部分。
