pdf Electron Microscopy مجانا للكاتب أحمد زويل
"Electron Microscopy" is a comprehensive guide to the principles and applications of electron microscopy in various fields of science. The book provides an overview of the development of electron microscopy and the different types of electron microscopes, including transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The authors discuss the basic principles of electron optics and imaging, as well as the preparation of specimens for electron microscopy.
The book covers a wide range of topics, from the study of biological specimens, such as cells and tissues, to the investigation of materials and their structures. The authors also discuss the use of electron microscopy in the fields of metallurgy, geology, and nanotechnology, among others.
One of the main strengths of electron microscopy is its ability to provide high-resolution images of specimens, allowing researchers to study the details of their structure and composition at the nanometer scale. The book explains the different imaging modes and techniques used in electron microscopy, including dark-field and bright-field imaging, diffraction and crystallography, and high-resolution imaging.
The authors also provide a comprehensive overview of the various sample preparation techniques used in electron microscopy, including fixation, embedding, sectioning, and staining. They discuss the advantages and disadvantages of different techniques, as well as the challenges involved in preparing specimens for electron microscopy.
Overall, "Electron Microscopy" is an essential reference for researchers and students in a wide range of fields who are interested in the principles and applications of electron microscopy. The book provides a clear and concise overview of the different types of electron microscopes, the basic principles of electron optics and imaging, and the sample preparation techniques used in electron microscopy.
