This award provides funds to assist in the purchase of a modern scanning electron microscope (SEM) for research in systematic biology and paleoecology at the Oklahoma Museum of Natural History (OMNH). In addition, the funds will assist in the purchase of a critical point dryer and a sputter coater, items required for the preparation of some types of materials for study with the SEM. The SEM to be purchased operates with variable pressure in the specimen chamber, and thus can image specimens at low pressure that are large (e.g., dinosaur teeth), too fragile (e.g., block of trilobite-rich shale), or too rare to be studied with conventional SEM preparation techniques. In addition, the SEM is capable of imaging very small, coated specimens (e.g., pollen, flowers) in the conventional high magnification/high pressure mode. Initially the instrument will be used by faculty/curators, research associates, graduate students, and undergraduates for studies of the systematics and evolution of flowering plants and heterosporous ferns, early Cretaceous vertebrates, Lower Paleozoic and Cenozoic bats, and other small mammals. The availability of the microscope will improve the research and educational capabilities of the University, and improve the museum's ability to preserve biological, paleontological, and archeological specimens while insuring their availability for research.

这项奖励提供资金帮助购买现代扫描电子显微镜(SEM)，用于俄克拉荷马自然历史博物馆(OMNH)的系统生物学和古生态学研究。此外，这笔资金将用于购买临界点烘干机和溅射镀膜机，用于准备某些类型的材料以供扫描电子显微镜研究。所购买的扫描电子显微镜是在样本室的可变压力下运行的，因此可以在低压下对大(例如恐龙牙齿)、太脆弱(例如富含三叶虫的页岩)或太稀有而无法用常规扫描电子显微镜制备技术进行研究的样品进行成像。此外，扫描电子显微镜能够在传统的高倍率/高压模式下对非常小的涂层标本(如花粉、花)进行成像。最初，该仪器将被教员/策展人、助理研究员、研究生和本科生用于研究开花植物和异源蕨类、早白垩世脊椎动物、下古生代和新生代蝙蝠以及其他小型哺乳动物的系统学和进化。显微镜的使用将提高大学的研究和教育能力，并提高博物馆保存生物、古生物和考古标本的能力，同时确保它们可用于研究。
