The Scanning Electron Microscope An SEM is a high essentially magnification microscope, which uses a focused scanned micron and submicron ranges. SEM generates high-energy electrons and focused on the specimen of the electron beam is scanned over the surface of the specimen in a motion similar to a television camera to produce a rasterized digital image. Electrons are speeded up in a vacuum until their wavelength is extremely short, only 100-1000 that of white light. Beams of these fast-moving electrons are focused on a sample and are absorbed or scattered by the specimen and electronically processed into an image. The primary electron beam interacts with the sample in several key ways as- The primary electron generates low-energy secondary electrons, which tend to emphasize the topographic nature of the specimen.  Primary electrons can be backscattered which produces images with a high degree of an atomic number...

The most important factors affecting its wide application are that the method is relatively easy rather than other processes. It provides a good enhancement for metallic biomaterial coating layers on the substrate. The sol-gel process is a versatile solution method for making nanoparticles. In general, the sol-gel process involves the transition of a system from a liquid ‘sol’ which is mostly a colloidal form converted into a solid ‘gel’ phase. The Block diagram of the sol-gel technique is shown in figure 1.4. An organic compound such as metal alkoxide/inorganic metal salts is used as precursors known as ‘sol’. During the process, the acid or base is added to maintain the pH of the solution. After converting the solution to a gel, the solvent is removed by centrifugation. With further drying, the gel is converted int...

Learn To Converge Your Dreams with Durgam Vigyan Sansthana Institute. Concepts of Physics by H.C. Verma. A textbook covering the fundamentals, with an Average language and good practical illustrations.   The author has generated a good flow to the text, which IMO is often overlooked in science/reference books. This makes it even more adorable.
