An Amplification Strategy to Label Free Opiate Drug Detection using Liquid-Gated Carbon Nanotubes Transistor

Tey J.N., Wijaya I.P.M., Wei J., Rodriguez I., Maisalkar S.G., Singapore Institute of Manufacturing Technology, SG

A label free, real time detection of opiate drug using the CNT liquid gated transistor is reported in this study. The device was fabricated using a facile method consists of two-step stamping and lamination process, [...]

Gels of Carbon Nanotubes and Nonionic Surfactant and High-quality Carbon Nanotube Films Prepared by Gel Coating

Ouyang J., National University of Singapore, SG

Processing of large-scale carbon nanotubes (CNTs) are very important for the application of CNTs in various aspects. Here, we report CNT gels by dispersing CNTs in various nonionic surfactants. High-quality CNT films were prepared by [...]

Carbon Nanotube Field Effect Transistors using Printed Semiconducting Tubes

Rouhi N., Jain D., Zand K., Burke P.J., Univ. of California-Irvine, US

Purified, all-semiconducting nanotubes offer great promise for a variety of applications in RF and microwave electronics. It has been showed theoretically that carbon nanotube electronic devices have the potential of going into THz regime since [...]

Carbon-based nanocomposite EDLC supercapacitors

Lei C., Lekakou C., University of Surrey, UK

Supercapacitors are electric devices with power and energy densities between those of a traditional capacitor and battery. As the demand for energy storage devices with high power and long durability increases, the supercapacitor becomes more [...]

Review of Double Wall Carbon Nanotubes, Synthesis and Applications (overview presentation)

Bacsa W., University of Toulouse, FR

We find that the Raman G band for individual double wall carbon nanotubes is split when the two walls are closely spaced or strongly coupled. We show that agglomeration of tubes into bundles leads to [...]

Interfacial Effect in Fe/ InGaAs Magnetism

Berrouachedi N., Rioual S., Lescop B., Rouvellou B., Langlois J., Bouslama M., Lounis Z., Abdellaoui A., ENSET d’Oran, DZ

The characterization of Ferromagnet / Semiconductor interfaces Fe/In0.5Ga0.5As system has been a topic of great interest because of the possible future development of spintronics, e.g., spin injection through the ferromagnetic thin film to the semiconductor. [...]

Nano Crystalline Cellulosic Nematic monocrystals optical properties

Picard G., Kadiri Y., Simon D., Ghozayel F., Lebreux J.-D., Ahuntsic College, CA

Magnificent opalescent effects are observed from the interaction between light and Nano Crystalline Cellulose (NCC). Leaving a thin liquid NCC suspension to slowly evaporate, a dry polycrystalline nematic cholesteric wafer was obtained. It was observed [...]
