Topics: Nanotechnology, Nanomaterials, Water Pages: 2 (513 words) Published: December 6, 2011
Nanotechnology is the manipulation of matter on a near-atomic scale to produce new structures, materials, and devices. This technology has the ability to transform many industries and to be applied in many ways to areas ranging from medicine to manufacturing. Research in nanoscale technologies is growing rapidly worldwide In the case of nanoscale materials, the uncertainties are great because the characteristics of nanoscle materials may be different from those of the larger particles with the same chemical composition.

The development of nanotechnology is very fast in the fields such as electronics,medical, biotechnology etc .The aim of presenting this paper is to understand the nanotechnology ,nanoparticles and its application in the treatment of water and wastewater also related application in the environmental engineering.


Nanotechnology involves the manipulation of matter at nanometer-length scales to produce new materials, structures, and devices Technology development at the atomic, molecular, or macromolecular range of approximately 1-100 nanometers to create and use structures, devices, and systems that have novel properties.There so many definitions are available in world wide which will vary different field of interest and person focused. By using the nanoscale materials pollutants from the water and wastewater is removed . NANOSCALE MATERIALS:

Instead of steel or aluminum being mined from the ground, new materials will be made from carbon atoms in the form of nanotubes and related structures. A single-walled, carbon nanotube is a strawlike structure with a one-atom-thick wall of carbon atoms. Lighter, stronger and more flexible than steel, carbon nanotubes are believed by many to be the most promising of all nanomaterials. Nanoscale titanium dioxide, for instance, is finding uses in cosmetics, sun-block creams, and self-cleaning windows. And nanoscale silica...
