While many fields of our current life and technology make use of the involvement of chemistry, even in a subtle way as quantum-, mathematical-, physical-, nano-, bio-, or eco-, and chemical disciplines, the chemistry itself drives almost all nature cycles through the atomic and molecular structure and reactivity universal principles. This book presents an interdisciplinary-internationally picture of chemical information embedded in various micro- and macro- systems in order to show how fertile the field of research and knowledge is thanks to chemistry.
