This book contains an overview of novel synthesis, characterization, and applications of nanomaterials. Based on an extensive state-of-the-art literature survey and results obtained from researches during the past years, this book presents techniques and special applications of classical and modern nanomaterials. This book reviews different nanomaterials, from the synthesis and characterization of diverse materials to modern applications such as viral detection, hyperthermia, thermoelectric, nano-coatings, electrochromic, pigments, among others. This book is aimed at students, researchers, and engineers who seek general scientific knowledge about nanomaterials with an application-oriented approach.

I am a professor at Universidade Federal do Rio Grande do Sul, working in the Materials Department. My main research focus is nanomaterials, especially applied to environment and energy fields such as photocatalysis, solar cells, hydrogen production. I am also working with materials synthesis and characterization, developing equipment and techniques. I have published more than 80 international papers, 5 books, 11 book chapters and oriented more than 50 master and pHD students.
