Transient Analysis on Nonlinear Model of Electrostatically Actuated Nanomechanical Switch

Kim I.K., Han D.H., Lee S.I., University of Seoul, KR

This research predicted the transient behaviors of a nano-switch with static and dynamic analysis. The nano-switch consists of a cantilevered MWCNT incorporating the electrostatic forces and intermolecular attractive and repulsive forces between the CNT and [...]

Differentiation of Complex Vapor Mixtures Using Versatile DNA-Carbon Nanotube Chemical Sensor Arrays

Kybert N.J., Lerner M.B., Yodh J.S., Preti G., Johnson A.T.C., University of Pennsylvania, US

Vapor sensors based on functionalized carbon nanotubes (NTs) have shown great promise, with high sensitivity conferred by the reduced dimensionality and exceptional electronic properties of the NT. Critical challenges in the development of NT-based sensor [...]

Decoupled Temperature and Moisture Sensor Made of CNT-Based Nanomaterials on Flexible Plastic Substrates

Diao L., Lamb J., Gibbons S., Shih W-S, Giedd R., Brewer Science, US

The moisture sensor is based on resistance change in the IDE structure. For the prototyped humidity sensors, a resistance change of more than 20% was observed while monitoring a moisture increase of 15% at room [...]

Novel, Flexible and Low-power Driven AC Electroluminescent Lamp from Carbon Nanotube Embedded Phosphor Material

Haranath D., Yadav D., Sahai S., Shanker V., CSIR-National Physical Laboratory, IN

 We present a novel, cost-effective and simple technique operable at room temperature, wherein a non-electroluminescent (non-EL) material is being converted to exhibit stable and efficient EL using CNTs.  The role of CNT has [...]

Structure and Electrical Properties of Polypropylene-Graphite-Carbon black/ Nanotubes Hybrid Conducting Composites

Ramanujam B.T.S., Mehta H., Khare A., Radhakrishnan S., Maharashtra Institute of Technology, IN

Low cost conducting composites are required for bipolar plates of fel cells and battery electrodes. Polypropylene filled with graphite has been tried in the past but acceptable level of conductivity is reached only at high [...]

Asphalt bitumen modified with carbon nanotubes

Boyer L., Barrera E.V., Rice University, US

We have introduced carbon nanotubes into asphalt bitumen (paving asphalt with no stone or sand aggregate) to investigate the effect on (1) strength, (2) viscoelasticity, and (3) exposure to microwave radiation.

New Electromagnetic Shielding Sheets Using Carbon-Nanotube-Composite Papers

Li B.J., Ito W., Hiwatashi H., Oya T., Yokohama National University, JP

We propose new electromagnetic shielding(EMS) sheets using carbon-nanotube(CNT)-composite papers. The paper has good electrical conductivity in spite of a paper, the weight is light, and there is no deterioration problem because of both the CNT [...]

Multifunctional Nanocomposites: Modeling and Characterization

Wernik J.M., Meguid S.A., University of Toronto, CA

Unlike traditional adhesive bonds, where only one material property is enhanced, multifunctional systems are capable of fulfilling several design requirements (e.g., strength/toughness, sensing, actuation, and condition monitoring). In this research, we intend to introduce this [...]
