At the nanoscale, with dimensions ranging between 1 and 100 nanometers, nanotechnology is the study and management of matter at the atomic and molecular level, where novel phenomena permit novel applications.
When compared to other forms or sizes of the same material, some nanostructured materials are stronger or have different magnetic properties than the other forms or sizes of the same material. Others are better at transferring heat or electricity than others. When their size or structure is changed, they may become more chemically reactive, reflect light better, or change colour due to the alteration.
Applications of Nano-Technology
After more than two decades of fundamental nanoscience research and more than fifteen years of dedicated R&D under the National Nanotechnology Initiative, nanotechnology applications are delivering on the promise of nanotechnology to improve society in both expected and unforeseen ways.
Many technologies and industry areas, including information technology, homeland security, medicine, transportation, energy, food safety, and environmental research, are benefiting from nanotechnology, which is helping to improve, if not completely revolutionize them significantly.
Materials and procedures using Nanotechnology
Several advantages of nanotechnology are based on the fact that it is feasible to change the structures of materials at extremely small scales to attain specific features, hence significantly expanding the materials science toolkit.
Textiles treated with nanoscale compounds or surface treatments can be used in personal body armour to provide lightweight ballistic energy deflection while also helping them resist wrinkling, staining, and bacteria growth.
With the development of nanoscale materials, washable, durable “smart fabrics” outfitted with flexible nanoscale sensors and electronics are becoming increasingly possible. These fabrics will have health monitoring, solar energy capture, and energy harvesting through movement.
The reduction in the weight of automobiles, trucks, aeroplanes, boats, and spacecraft could result in significant fuel savings.
Invisible particles that fight cancer cells, quicker microprocessors that require less energy, batteries that last ten times longer, and solar panels that produce twice as much energy are all possibilities. These are only a few of the uses of nanotechnology, a subject that has all of the components to become the next industrial revolution in the coming years.
