Aligned Carbon Nanotubes For Multifunctional Nanocomposites and Nanodevices L Dai, L Qu (Univ of Dayton) We have previously developed a simple pyrolytic method for large-scale production of aligned carbon nanotube arrays perpendicular to the substrate. These aligned carbon nanotube arrays can be transferred onto various substrates of particular interest in either a patterned or non-patterned fa...

Multilayered, aligned arrays of organic nanowires show unique advantages in their piezoelectric response. Here, the cooperative, electromechanical mechanism at the base of the enhanced response of aligned arrays of piezoelectric nanostructures in mutual contact is unveiled. An enhancement of the piezoelectric voltage by two orders of magnitude compared with individual nanofibers is demonstrated...

The chemical vapor deposition growth of unusual arrangements of single-walled carbon nanotubes (SWNTs) by the combined of use patterned catalysts and quartz substrates is reported. Nearly perfectly aligned, high-coverage arrays of SWNTs can be generated in this manner. High-coverage random networks of SWNTs can also be created in the same growth step, with good spatial alignment and electrical ...

In the past, aligned arrays of carbon nanotubes (CNTs) have been observed to exhibit a foam-like dissipative response in compression, garnering attention for possible mechanical applications. Nanoparticles have previously been integrated with graphitic materials for electrochemical applications. Here, we synthesize nanoparticles of SnO2 and MnO2 in the interstices of aligned arrays of CNTs with...

We report an approach for growing aligned ZnO nanowire arrays with a high degree control over size, orientation, dimensionality, uniformity, and possibly shape. Our method combines e-beam lithography and a low temperature hydrothermal method to achieve patterned and aligned growth of ZnO NWs at <100degreesC on general inorganic substrates, such as Si and GaN, without using catalyst. This approa...
