Nanotechnology never ceases to amaze me. The nano particles have made gadgets and devices so tiny that we could not even have dreamed about such advanced technologies. Researchers have found out how water behaves inside carbon nanotubes and this discovery could help in the realization of ultra small devices and also help in medicine and others. In fact the discovery could have far reaching consequences. The so-called nano-confined water changes its structure in a limited space as that of a hollow carbon nanotube.
Normally Graphene repels water, but researchers found out that in such tiny spaces, water changes its properties and in fact Graphene does not repel water because the size becomes so small. Temperature also played a major role in this. When the temperature was reduced from 22 degrees to 8 degrees, the carbon nanotubes became more water friendly.

I had always heard the stories of the flying carpet and at the same time was sure that it was possible strictly in fairytales. But it seems the scientists at the Imperial College of London are all set to materialize the fairytales. No, they are not inventing a carpet that could fly, but for sure they are tying to conjure up a carpet that can make you appear as if flying as it gets invisible in visible light.
They have almost developed, what is called an invisible carpet, which comes to for as a successful cloaking device that provides complete invisibility unlike others.
Using metamaterials, which channel light in a way that is less than the wavelength of light that creates a mirage of invisibility using nanotechnology. Materials like silicon and silica will be used to make this carpet as they are ideal to create a physical gradient. Though just a concept till now, but it is definitely a move in the right direction to materialize the fantasy of flying in air on an invisible carpet.
