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 [...]

Carbon nanotube/fused silica composite with gradient structure and carbon fiber/ fused silica back reflection layers for microwave absorbing application

Zhu Y., Pan Y.B., Guo J.K., Chinese Academy of Sciences, CN

Many investigations have been made to the carbon nanotube (CNT)/pure silica (SiO2) composites for their attractive properties. Our primary work demonstrates the decrease of reflection at interface and the improvement of microwave absorbing efficiency in [...]

From Electrical to Fuel Powered Artificial Muscles

Kozlov M.E., Oh J., Mirfakhrai T., Zhang M., Fang S., Ferraris J.P., Madden J.D.W., Baughman R.H., University of Texas at Dallas, US

A number of materials ranging from carbon nanotube yarns and sheets to shape memory alloys (SMA) have been explored for the application in the area of artificial muscles (actuators). It was found that if powered [...]

Nanotube Grafting in Porous Solids for High Surface Devices

Mukhopadhyay S.M., Karumuri A., Barney I.T., Wright State University, US

Biological systems make use of hair and capillary type hierarchical structures to create more surface area in limited space, but very few synthetic materials use this concept. Geometrical calculations show that if hierarchical substrates are [...]

Preparation and Electrochemical Characterization of Porous SWNT-PPy Nanocomposite Sheets for Supercapacitor Applications

Oh J., Kozlov M.E., Baughman R.H., University of Texas at Dallas, US

Highly porous sheets comprised of Single Walled Carbon Nanotubes and doped polypyrrole (SWNT-PPy) were prepared by vacuum filtration of SWNT-PPy methanol dispersions. The employed preparation procedure is an extension of conventional bucky-paper fabrication method for [...]

Influence of MWNT on the physical properties of polyethylene nanocomposites

Ciambelli P., Sarno M., Neitzert H.C., Nobile M.R., Somma E., Valentino O., University of Salerno, IT

Physical properties of a series of multi-walled carbon nanotube-high density polyethylene (MWNT-HDPE) composites, prepared by melt mixing in a micro-twin screw extruder, were investigated. The effect of MWNT concentration (0.5-7 wt%) and nanotube surface treatment [...]

Tribological properties of carbon nanotubes as lubricant additives

Abate F., Senatore A., D’Agostino V., Leone C., Sarno M., Ciambelli P., University of Salerno, IT

Tribological performances of innovative lubricant additives based on IF-WS2 and other transition metal dichalcogenides like MoS2 nanoparticles have been widely investigated in recent years. The boundary lubrication regime is the main target for the benefits [...]
