چکیده
This colorized, perspective SEM image shows aligned arrays of single-walled carbon nanotubes grown on a quartz substrate in two sequential cycles of chemical vapor deposition (red and blue), as reported by John Rogers and co-workers. The gold line depicts an electrode contact to the array. The SEM image in the background shows regions of dual and single growth on the left and right, respectively.

Separation of Salmonella Typhimurium Bacteria from Water Using MWCNTs Arrays
In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...
متن کاملDistribution of Residual Stresses in Polymer Reinforced Carbon Nanotubes and Laminated Carbon Fibers
In this study, the distribution of residual stress in fiber-reinforced nanocomposites is investigated. Fiber-reinforced nanocomposite is composed of three substances: carbon fiber, carbon nanotube (CNT), and polymer matrix. Unit cells in hexagonal packing array with different arrays as unit cell, 3*3 and 5*5 arrays have been selected as suitable for finite element analysis of residual stresses....
متن کاملEnhanced Efficiency in Dye-Sensitized Solar Cells by Electron Transport and Light Scattering on Freestanding TiO2 Nanotube Arrays
Dye-sensitized solar cells (DSSCs) were fabricated with closed- or open-ended freestanding TiO₂ nanotube arrays as photoelectrodes that were decorated with carbon materials and large TiO₂ nanoparticles (NPs) to enhance energy conversion efficiency. The energy conversion efficiency of DSSCs based on open-ended freestanding TiO₂ nanotube arrays increased from 4.47% to 5.39%, compared to the DSSCs...
متن کاملNovel nanotube-on-insulator (NOI) approach toward single-walled carbon nanotube devices.
We present a novel nanotube-on-insulator (NOI) approach for producing high-yield nanotube devices based on aligned single-walled carbon nanotubes. First, we managed to grow aligned nanotube arrays with controlled density on crystalline, insulating sapphire substrates, which bear analogy to industry-adopted silicon-on-insulator substrates. On the basis of the nanotube arrays, we demonstrated reg...
متن کاملPhysicochemical characteristics and droplet impact dynamics of superhydrophobic carbon nanotube arrays.
The physicochemical and droplet impact dynamics of superhydrophobic carbon nanotube arrays are investigated. These superhydrophobic arrays are fabricated simply by exposing the as-grown carbon nanotube arrays to a vacuum annealing treatment at a moderate temperature. This treatment, which allows a significant removal of oxygen adsorbates, leads to a dramatic change in wettability of the arrays,...
متن کاملCarbon nanotube conducting arrays by consecutive amidation reactions.
Carbon nanotube conducting arrays were constructed via consecutive amidation reactions with the aid of a linker molecule and a condensation agent on a patterned amine-terminated glass substrate. The electrical resistivity of the nanotube films was sensitive to the degree of coverage for the substrate, making it possible to tailor nanotube multilayers suitable for use in micro- or nanoscale elec...
