Description: Chemistry is an interesting and fundamental branch of science because it gives us the chance to explain the secrets of nature. What is water? What do we use in our cars as a fuel? What is aspirin? What are perfumes made of? Many of these kind of questions and their answers are all part of the world of chemistry. There is no industry that does not depend upon chemical substances: petroleum, pharmaceuticals, garment, aircraft, steel, electronics, agricultural, etc. This book helps everyone to understand nature. However, one does not need to be a chemist or scientist to understand the simplicity within the complexity around us.
Since the discovery of the insulating nature of the transition-metal oxides with incompletely filled 3d shells in 1937, the interest in this fascinating class of compounds, in particular in their electronic structure, has never vanished. Presently, research in this field is gaining increasing importance because a detailed knowledge of the oxides' bulk and surface electronic structure is essential for understanding and optimizing the mechanisms relevant to the growing number of technological applications of these materials, which are used in lasers, sensors, and catalysis. In this monograph, the present knowl- edge about the electronic structure of the monoxides NiO, CoO, and MnO is briefly reviewed, particularly with respect to the 3d electrons, which remain localized at the transition-metal ions because a strong Coulomb correlation prevents them from forming a partially filled 3d conduction band, leading to the insulating behavior.
