This book aims to provide an insight into the synthesis and applications of varying materials in their aerogel form. The book covers the recent advances and reviews the state of the art of aerogels prepared from varying nanomaterials including carbon nanomaterials, silica, bioaerogels and hybrid aerogels in applications such as energy storage, electronics, or environmental remediation, in terms of water and air. The book serves as a fundamental information source on the techniques and methodologies applied to obtain the aerogel form of different nanomaterials, their characterization, and their post-synthesis modification or hybridization. The information enclosed in this book will be invaluable for experts to consolidate their knowledge and provide insight for newcomers to the field. Moreover, the book also includes the evolution of student satisfaction regarding a novel teaching approach based on the use of a teaching mobility event (International Week) as a platform to introduce engineering students to nanotechnology and specifically to graphene aerogels which could serve to improve teaching abilities and outcomes.
