This book includes the synthesis, analysis and characterization of nanomaterials that are an important ingredient in nanotechnologies. Nanomaterials contain nanoparticles, smaller than 100 nanometers in at least one dimension. Nanomaterials are coming into use in health care, electronics, cosmetics and other areas. Their physical and chemical properties differ from those of bulk materials. This needs to cover health risks to workers and potent...

The semiconductors have energy gap separates the electron energy levels that are normally filled with electrons from those that are empty of electrons. Si, SiC and GaN have bond strengths suitable for high-temperature applications. Porous Si, SiC and GaN can be formed by photo-electro-chemical etching and those have unique properties and applications as electro-optical devices, fuel cells, sensors and actuators. The book presents for both expe...

The empirical concepts as electronegativity, ionicity and bulk modulus are very important for studying the basic properties of solids. The difficulty in defining the ionicity and bulk modulus lies in transforming a qualitative or verbal concept into a quantitative, mathematical formula. My works concentrated on using empirical pseudopotential method (EPM) to calculate electronic properties (ionicity factor) fi in terms of the difference betwee...
