Surface Coatings [PDF ebook] 

This new book is dedicated to outstanding research in nanotechnology which is a "catch-all" description of activities at the level of atoms and molecules that have applications in the real world. A nanometer is a billionth of a meter, about 1/80, 000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques.
