This book (part A and partB, the present one) was written by 76 authors, among best specialists of the field, at the intention of academics, researchers, engineers, graduated and undergraduated students wishing to update their knowledge and understanding of the covered class of materials. It presents perovskites but also other Framework Structure crystalline materials (based on units that share their corners with neighbours). Perovskites are among the most famous materials due to their exceptional properties: they present nearly all existing types of interesting properties, in particular as ferroics or multiferroics, they may be insulators, (super)conductors, or semiconductors, magnetoresistant, they are used in numerous devices, they present hundreds of variants and different crystalline phases and phase transitions, and recently appeared as probably the most promising materials for photovoltaics. After part A Fundamental aspects and general properties, we present part B (the present one) Elaborated materials and applied properties, containing 14 chapters. Examples of elaborated materials belonging to the family of Framework Structure materials are presented (with potential applications), and their preparation and/or properties as single crystals, ceramics, thin films, multilayers, nanomaterials, nanofibers, nanorods, etc, are discussed. We focus on new trends and important recent developments by leaving somewhat aside more classical aspects which can be easily found in older textbooks or review articles. Among applications we focus on molecules encapsulation, gas adsorption, photovoltaics, typical applications related to ferroelectricity, and memory devices. In conclusion, this book presents a collection of texts elucidating various aspects of the relation between structural organization (including dynamical aspects) and singular properties of framework crystals. The volume proposes a reasonable balance between fundamental aspects (part A) and applied properties (part B). It can be approached on several levels (each chapter initially assumes that the reader is not a specialist in the subject and is presented in a pedagogical way): it is accessible to master or doctoral students, as well as to researchers who want to have informations on recent developments. It may be used also by undergraduate students who should approach given subjects. This part contains the general index and preface and is completed by numerous figures to illustrate the text.
