Building Nanostructures Atom by Atom. This book provides an introduction to computational materials science in the design of novel nanomaterials. The author draws upon his first-hand experiences designing nanoscale materials with atomic scale controls using mainly quantum and atomistic modeling methods. The purpose is to introduce multiscale materials modeling in a materials design framework, outlining pathways from design to industrial applications. This book shows how to connect fundamental modeling methods with practical design principles when developing a commercial product.
