New Fullerenes Findings from Technical University Discussed

May 26, 2014

By a News Reporter-Staff News Editor at Clinical Trials Week -- Researchers detail new data in Fullerenes. According to news reporting from Kuala Lumpur, Malaysia, by NewsRx journalists, research stated, "Carbon Nanotubes (CNTs) are generally nano-scale tubes comprising a network of carbon atoms in a cylindrical setting that compared with silicon counterparts present outstanding characteristics such as high mechanical strength, high sensing capability and large surface-to-volume ratio. These characteristics, in addition to the fact that CNTs experience changes in their electrical conductance when exposed to different gases, make them appropriate candidates for use in sensing/measuring applications such as gas detection devices."

The news correspondents obtained a quote from the research from Technical University, "In this research, a model for a Field Effect Transistor (FET)-based structure has been developed as a platform for a gas detection sensor in which the CNT conductance change resulting from the chemical reaction between NH3 and CNT has been employed to model the sensing mechanism with proposed sensing parameters. The research implements the same FET-based structure as in the work of Peng et al. on nanotube-based NH3 gas detection. With respect to this conductance change, the I-V characteristic of the CNT is investigated."

According to the news reporters, the research concluded: "Finally, a comparative study shows satisfactory agreement between the proposed model and the experimental data from the mentioned research."
