Abstract

Carbon Nanotubes were discovered by Iijima in 199. Then they have been recognized as exciting and fascinating novel material which have specific physical and chemical characteristics and lead to playing a vital role in developing tremendous technological applications. Multi-walled carbon nanotubes, ‘MWCNTs’ were obtained by the arc discharge technique in an atmosphere of Ar and H2 mixture The catalyst was prepared from a mixture of Ni, Y, Co and Fe. They allow the realization of a quasi-one-dimensional environment for the materials diffused inside, particularly, the case of water inside such nano-chanels has recently received consequences. Transport of molecules through molecular pores like nanotubes is essential for many biological and technical applications. The water self-diffusion coefficients help to quantify the state of absorbed water in each system. More loosely bound water yields a higher self-diffusion coefficient, while more tightly bound water yields a lower self-diffusion coefficient. As a novel application we can use the flow of water inside carbon nanotubes as snapshot to measure the pressure inside very soft cells of biological systems when the water goes through its shape by capillary behaviour. Other good application of carbon nanotubes composite is the photovoltaic cells, the most important inspiration is to produce a low cost, renewable energy source which will help to solve the world’s frightening energy crisis, electrical energy from the sun (photovoltaics PV) is considered as one of the mainly future and environmental-friendly source of energy.
