An evaporator/sputter-coating apparatus will be purchased for use with a high resolution scanning electron microscope to support research in membrane science, biotechnology, combustion and coal gasification research at the University of Colorado at Boulder. The high energy electron beam used in SEM analysis can cause charging as well as thermal degradation in nonconducting, thermally sensitive materials such as polymeric membranes and microbial cells. This problem is minimized by applying a coating of conductive metal or a carbon coating to the materials. Small scale structures, however, such as nodules on polymeric membranes and pili on microbial cells can be masked by conventional techniques. The equipment to be purchased features electron beam evaporative coating capability to achieve ultrathin, fine-grained conductive films required for ultrahigh resolution SEM analysis.

将购买蒸发器/溅射涂层设备，与高分辨率扫描电子显微镜一起使用，以支持科罗拉多大学博尔德分校的膜科学、生物技术、燃烧和煤气化研究。 SEM 分析中使用的高能电子束可能会导致聚合物膜和微生物细胞等非导电热敏材料带电和热降解。 通过在材料上涂覆导电金属涂层或碳涂层可以最大限度地减少这个问题。 然而，小规模结构，例如聚合物膜上的结节和微生物细胞上的菌毛，可以通过常规技术掩盖。 待购买的设备具有电子束蒸发镀膜能力，可实现超高分辨率 SEM 分析所需的超薄、细晶粒导电薄膜。
