1.1 Introduction
The last two decades have witnessed the explosion of nanoscience and nanotechnology.
Particularly, the establishment of the National Nanotechnology Initiative (NNI) at the end
of the last century has greatly stimulated research in this new eld [1–5]. The research
efforts have produced a plethora of methods for the synthesis, characterization, computer
simulating, theoretical modeling, manufacturing, and applications of nanomaterials
that have at least one dimension on the nanoscale (1–100 nm). Nanomaterials with t ...
