"When we manage to make devices well on the nanoscale, we can then move on to make much smaller and finer structures that will go beyond conventional transistors to open up the possibility for more sophisticated devices that use electrons more like light than particles," he said. "If we can factor quantum mechanical features into electronics, that is going to open up a lot of new possibilities."

This self-cooling effect means that graphene -based electronics could require little or no cooling, begetting an even greater energy efficiency and increasing graphene's attractiveness as a silicon replacement.

Nanotechnology being the most dynamic and rapidly developing areas of interdisciplinary research in applied engineering has revolutionised with a wide range of scientific and technological fields because of its inherent distinguished physical and chemical properties at the nanoscale. The research works reported on material science aims at adopting the advanced state-of-the-art of nanofabrication and its application to the nanoscience and nanotechnology fields. The work reported here focuses on the development of Nano-composites for varied engineering applications.

The latest improvements have resulted in a nanogenerator powerful enough to drive commercial liquid-crystal displays, light-emitting diodes and laser diodes. By storing the generated charges using a capacitor, the output power is capable to periodically drive a sensor and transmit the signal wirelessly.
