RADARS
The first to use radio waves to detect "the presence of distant metallic objects”
first established principles regarding frequency and power level for the first primitive radar units
RAPID capable of detecting an aircraft within 3 km of a receiver.
The British were the first to fully exploit radar as a defense against aircraft attack.
the US Army and US Navy were working on radars with the same principle
The war precipitated research to find better resolution, more portability and more features for radar.
INTRODUCTION
What is NanoTechnology?
Nanotechnology is regarded as a key technology
It will not only influence technological development in the near future, but will also have economic, social and ecological implications.
will also have economic, social and ecological implications.
Nanotechnology deals with the science and technology at dimensions of roughly 1 to 100 nanometers (1 Billion Nanometers = 1 Meter), although 100 nanometers presently is the practically attainable dimension for textile products and applications
Conventional methods used to impart different properties to Fabrics often do not lead to permanent effects, and will lose their functions after Laundering or wearing.
Nanotechnology can provide high durability for fabrics, because nano-particles have a large surface area-to-volume ratio and high surface energy
DESCRIPTION
The Israel-based YnetNews is Reporting that an Israeli company called Nanoflight
It has successfully run a test on dummy missiles .
that were painted with the nano-enabled coating and have shown that radar could not pick them up as missiles.
The nanocoating achieves its radar trickery by absorbing the radio waves emitted by the radar and scattering them as heat energy enough so that when the radar gets the bounced back signal it is not regular enough to indicate an object.
A spokesman for Nanoflight, Eli Shaldag, is quoted in the article indicating that the company is in the second stage of its development process after which they will be able to produce the coating in larger quantities.
CONSTRUCTION
Nanomaterial use in construction, in coatings, in site remediation, and on invisible planes
Certain nanomaterials can improve the strength of concrete, serve as self-cleaning and self-sanitizing coatings
These paving slabs are coated with titanium dioxide (TiO2)
Titanium dioxide is a photo catalyst; it uses sunlight to accelerate a naturally occurring
An Israeli company has developed a paint for airplanes that can make them invisible to radar.

EXPLANATION
Carbon Nanotubes (CNTs), graphene and their compounds exhibit extraordinary electrical properties for organic materials.
Have a huge potential in electrical and electronic applications such as photovoltaics, sensors, semiconductor devices, displays, conductors, smart textiles and energy conversion devices (e.g., fuel cells, harvesters and batteries).
Applications of Carbon Nanotubes and Graphene for electronics applications
Depending on their chemical structure, carbon nanotubes (CNTs) can be used as an alternative to organic or inorganic semiconductors as well as conductors, but the cost is currently the greatest restraint.
However, that has the ability to rapidly fall as new, cheaper mass production processes are established, which we cover in this report.
In electronics, other than electromagnetic shielding, one of the first large applications for CNTs will be conductors.
In addition to their high conductance, they can be transparent, flexible and even stretchable. Here, applications are for displays, replacing ITO; touch screens, photovoltaics and display bus bars and beyond.
CONCLUSION
Nano paints enabled coating makes aircraft invisible
Radar can’t detect aircraft
In future there is a scope to attack terrorists shelters
Reduced emissions and noise of aircraft
Increased safety and mobility of aircraft in future
