PREPARATION, DEVELOPMENT AND APPLICATIONS OF NANOMATERIALS-REVIEW
G.S.C. Bose* and I. Hatti
ABSTRACT
The prefix ‘nano’ is derived from the Greek word for dwarf. One
nanometre (nm) is equal to one-billionth of a metre, 10–9m. The
conceptual underpinnings of nanotechnologies were first laid out in
1959 by the physicist Richard Feynman. Nanomaterials research takes
a materials science-based approach to nanotechnology, leveraging
advances in materials metrology and synthesis which have been
developed in support of microfabrication research. The properties of
materials can be different at the nanoscale for two main reasons. First,
nanomaterials have a relatively larger surface area when compared to
the same mass of material produced in a larger form. Metal
nanoparticles are used as various types of catalysts, adsorbents, sensors and ferrofluids.
Nanoparticles have potential applications in many different fields. Engineered nanoparticles
are specifically designed and formed with customized physical properties in order to fulfill
the requirements of specific applications.Nanomaterials are used such as electronics, Energy,
Automobile, Aerospace, Medical, Cosmetics, Food, Sports equipment, Textile industry,
Technology and home appliances.
Keywords: Nano, Nanomaterials, Nanoparticles and Nanoscale.
