Engineering Research Equipment Grant: A Cryo Stage and a Digital Image Processor for an SEM

正在购买用于扫描电子显微镜的冷冻级和数字图像处理器。该仪器被用来观察不对称聚合物膜的形态，并研究单细胞巨型孢子囊藻。低温层使扫描电子显微镜的分辨率提高了几倍，并允许观察20nm量级的结构，而不会出现在透射电子显微照片中复制结构时可能出现的畸变。使用该仪器获得的结果将为膜形成模型提供额外的确认，并可能有助于设计用于分离目的的最佳设计的不对称膜。关于单细胞生长的新信息也将从藻菌的研究中获得。

A cryostage and digital image processor for a scanning electron microscope is being purchased. This instrument is being used to view the morphology of asymmetric polymer membranes and to investigate the single-celled giant sporangiophore, Phycomyces. The cryostage increases the resolution of the scanning electron microscope by several-fold and permits the viewing structures of the order of 20nm without the distortion which may take place when structure replicas must be made for transmission electron photo micrographs. Results obtained using this instrument will provide additional confirmation of the membrane formation model and may contribute to the design of optimally designed asymmetric membranes for separation purposes. New information on the growth of single cells also will be forthcoming from the work on Phycomyces.
