In this article we will discuss about:- 1. Principle of Transmission Electron Microscopy 2. Components of Transmission Electron Microscopy 3. Applications. Principle of Transmission Electron Microscopy: The transmission electron microscope can be compared with a slide projector. In a slide projector, light from a light source is made into a parallel beam by the condenser lens; this passes through the [...]
In this article we will discuss about:- 1. Principle of Scanning Electron Microscopy 2. SEM Equipment 3. Working Mechanism 4. Specimen Preparation 5. Image Treatment and Analysis 6. Advantages and Applications. Principle of Scanning Electron Microscopy: SEM equipment is similar to a television. The principle of SEM is to use a focused beam of high-energy electrons to generate a variety of [...]
Clay minerals in soils can be identified using one or more of the following methods: 1. X-ray diffraction (XRD) 2. Differential thermal analysis (DTA) 3. Transmission electron microscopy 4. Scanning electron microscopy 5. Infrared spectroscopy. Method # 1. X-Ray Diffraction: X-ray diffraction (XRD) technique is one of the most commonly used methods to identify the minerals present in a soil, [...]
