Mechanomutable carbon nanotube arrays
International Journal of Materials and Structural Integrity, 2009Here we present atomistic-based multi-scale simulation studies of a magnetically active array of carbon nanotubes to illustrate the concept of mechanomutability. We show that applying external fields, it is possible to change the nanostructure and to induce a desired mechanical response.

Carbon nanotube array actuators
Smart Materials and Structures, 2013Experimental investigations of highly vertically aligned carbon nanotubes (CNTs), also known as CNT-arrays, are the main focus of this paper. The free strain as result of an active material behavior is analyzed via a novel experimental setup. Previous test experiences of papers made of randomly oriented CNTs, also called Bucky-papers, reveal ...

Neural Stimulation with a Carbon Nanotube Microelectrode Array
Nano Letters, 2006We present a novel prototype neural interface using vertically aligned multiwalled carbon nanotube (CNT) pillars as microelectrodes. Functionalized hydrophilic CNT microelectrodes offer a high charge injection limit (1-1.6 mC/cm2) without faradic reactions.

Transmission and scattering properties of carbon nanotube arrays
2009 International Symposium on Electromagnetic Compatibility - EMC Europe, 2009This paper investigates the behavior of an array of parallel Carbon Nano Tubes (CNTs), when it is illuminated by a plane wave. Transmission and scattering properties are quantified. This analysis may be used in the future as a reference for shielding applications based on CNT arrays.

Carbon Nanotube Based Infrared Detector Array
2008 8th IEEE Conference on Nanotechnology, 2008As a promising nanomaterial, carbon nanotube (CNT) has been studied for infrared sensing with their unique properties such as wide range of band gaps and reduced carrier scattering. However, due to the traditional inefficient and unreliable fabrication processes, the research of CNT based infrared sensors remained on the single pixel study, which ...

Ice-Assisted Transfer of Carbon Nanotube Arrays
Nano Letters, 2015Decoupling the growth and the application of nanomaterials by transfer is an important issue in nanotechnology. Here, we developed an efficient transfer technique for carbon nanotube (CNT) arrays by using ice as a binder to temporarily bond the CNT array and the target substrate.

Acta Physico-Chimica Sinica, 2008
Abstract A simple acid treatment method was applied to remove the catalyst impurities and other residues contaminated in the vertically aligned carbon nanotube arrays. We demonstrated that acid treatment was an efficient approach for aligned carbon nanotube purification.

The growth of freestanding single carbon nanotube arrays
Nanotechnology, 2003Regular arrays of freestanding single carbon nanotubes (CNTs) were prepared on Ni dot arrays by dc plasma-enhanced chemical vapour deposition. The size of the Ni dot was reduced for single CNT growth by means of conventional photolithography and a lateral wet-etch process. The vertical alignment of a single CNT was directly dependent on the location of

Carbon nanotube array: A new MIP platform
Biosensors and Bioelectronics, 2009Here we demonstrate that a free-standing carbon nanotube (CNT) array can be used as a large surface area and high porosity 3D platform for molecular imprinted polymer (MIP), especially for surface imprinting. The thickness of polymer grafted around each CNT can be fine-tuned to imprint different sizes of target molecules, and yet it can be thin enough ...

Computer generated holograms for carbon nanotube arrays
Nanoscale, 2013Multiwalled carbon nanotubes are highly diffractive structures in the optical regime. Their metallic character and large scattering cross-section allow their usage as diffractive elements in Fraunhofer holograms. This work elaborates some important features of the far field diffraction patterns produced from periodic arrays of nanotubes.
