ABSTRACT
Nanotechnology is pervasive in contemporary life. With applications in food, electronics, medicine, cosmetics, catalysis, construction, defense etc. Many of natural materials around us have a nanostructure that determines their behavior. Nanoscience and nanotechnology generally deal with objects that have one or more dimensions in the range of 1-100 nm. This range is arbitrarily fixed by convention and sometimes must be expanded. Modern nanoscience and nanotechnology really started about three decades ago when it was demonstrated that it is possible to observe and manipulate nano-objects. Before that, most manufactured nanomaterials were films or coatings with thicknesses in the range of 1-100 nm.
