A critical review of nanotechnology in various fields of engineering.

In recent years, nanotechnology has been explored with great interest due to its usage in various fields like physics, chemistry, material science, medical and engineering. The nanotechnology is emerged as major research area for researchers. The nanotechnology fabricates, characterizes and handles the materials at nanoscale. Nanotechnology applications commonly include industrial, medical and energy applications. Reducing the particle size to a nano-scale enhances several properties of the materials for example, durability, strength, ductility, density of the construction materials, buoyancy, ruggedness, storage efficiency of Li batteries etc. [ABSTRACT FROM AUTHOR]
