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. Composition of Clay Minerals 2. Isomorphous Substitution 3. Properties of Clay Minerals. Composition of Clay Minerals: Clay minerals in soils belong to phyllosilicates group of minerals, which in turn belong to silicate minerals. Silicate minerals make up about 90% of the rock-forming minerals of the earth's crust. The word Phyllon in the [...]
