This project involves the purchase, installation and use of an Environmental Scanning Electron Microscope to be housed in the Microscopy Suite Facility of the Beckman Institute at the University of Illinois, Champaign. The requested instrument will provide the only access to environmental SEM and the only instrument available for biological research on the UIUC campus. This instrument provides the unique capability for examining specimens with a field emission source electron beam at a residual gas pressure range in the specimen chamber which can exceed the saturated water vapor pressure. Thus, water-containing samples can be viewed without prior drying. The instrument will be used by over 20 research groups involved in a broad range of research including biomaterials, plant lichens, insect antennal tissue and textiles.

该项目涉及购买、安装和使用一台环境扫描电子显微镜，该显微镜将被安置在尚潘伊利诺伊大学贝克曼研究所的显微镜套件设施中。所要求的仪器将提供唯一的环境SEM和唯一的仪器可用于在UIUC校园生物研究。该仪器提供了独特的能力，用于检查样品与场发射源电子束在残余气体压力范围内的样品室，可以超过饱和水蒸汽压力。因此，含水样品可以在没有预先干燥的情况下观察。 该仪器将被20多个研究小组使用，涉及广泛的研究，包括生物材料，植物地衣，昆虫触角组织和纺织品。
