ISO16700是一套关于微束分析(Microbeamanalysis)的标准化指南,主要涉及到扫描电子显微镜(Scanningelectronmicroscopy,简称SEM)的操作和应用。此标准主要是为科研人员、技术人员以及教育工作者提供了一种对于SEM操作的重要技巧和原理的理解。在微束分析中,通常会用到各种电子显微镜,如SEM,以便于对物质进行高精度的观察和研究...
Our laboratory undertook extensive light, transmission (TEM) and scanning elctron microscope (SEM) studies of rat lenses during the development and reversal phase of galactose-induced cataracts. These studies were undertaken in order to gain insight into the morphological manifestation of known biochemica...

How SEMs work In scanning electron microscopy, the electron beam scans the sample in a raster pattern. First, electrons are generated at the top of the column by theelectron source. These are emitted when their thermal energy overcomes the work function of the source material. They are then ...
