Chemistry is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes in undergoing chemical reactions. This Encyclopaedia distills the essence of the important topic for graduate students, and for researchers in other fields who are interested in getting a general insight into Solid Chemistry. It describes the chemical and physical properties and behaviour of the complex assemblies that form an applications which arise as a result of these properties. This encyclopaedis is comprehensive package for knowledge sharing on chemistry. The language of the encyclopaedis is simple and self–explanatory; helps the students to grasp the fundamentals of the subject easily. The encyclopaedis follows a to the point approach, it lays stress on the understanding of the core concepts. This encyclopaedis explores the latest advances in the field of inorganic chemistry. It is intended for the students of graduate or postgraduate level inorganic chemistry courses of various universities.
