All the existing methods of chemical modification of carbon nanotubes (CNTs) can be divided in two groups, depending on whether functionalizing moieties are introduced onto the nanotube tips or sidewalls. The latter approach offers wider [...]
Various endohedral cage compounds have been suggested as possible candidate species for molecular memories. One approach is built on endohedral species with two possible location sites of the encapsulated atom while another concept of quantum [...]
Fullerene (C60) is a promising material for nano-carbon device research. Control of the electrical property of C60 is necessary for applications. C60 polymer has great promise because its unique structure allows its electrical and optical [...]
In 1967, "Hexagonal diamond - a new form of carbon" was reported to be found in meteorites. This hexagonal form, 2H, was named Lonsdaleite, after the noted crystallographer, Kathleen Lonsdale. Since the corrected structures and [...]
Narrow diameter double walled carbon nanotubes can now be grown by the catalytic chemical vapor deposition process with high yield. Double walled carbon nanotubes are the molecular analogs to coaxial cables and they can also [...]
Technological leaps of the last two decades have opened windows of opportunity for designing and controlling electronic states in novel systems. The fabrication of quantum dots in semiconductor devices has led to the invention of [...]
We present a method to produce carbon nanotubes by decomposition of hydrocarbons using an arc-jet plasma of high temperature (500020000 K). Carbon nanotubes are continuously produced in a floating condition by introducing a hydrocarbon gas [...]
2D arrays of single-walled Carbon Nanotubes (SWNTs) have been grown on Silicon substrates of both Si(100) surface and Si(111) surface by using chemical vapor deposition (CVD). The two-fold growth symmetry on Si(100) and three-fold growth [...]

Currently known processes for carbon nanotube synthesis use either of the following methods: Arc, laser, solar, plasma or catalytic method. The first group, comprising the first four processes corresponds to the high temperature methods. Hereby, [...]
We report here a novel micromachined single wall carbon nanotube (SWNT)/tin dioxide (SnO2) nano film gas sensor. A polymeric sol-gel process in combination with purified SWNT has been successfully developed in fabricating SWNT/SnO2 thin film [...]
We have previously demonstrated two different configurations of integrally gated carbon nanotube field emitter arrays (FEAs). CNTs were grown inside microfabricated gate apertures with and without silicon posts. Salient features of these in-situ grown microgated [...]
Single-walled carbon nanotubes (SWNTs), due to their novel structural, thermal, electrical, mechanical and optical properties, are expected to find applications in many fields. Pristine SWNTs are generally insoluble in common solvents, and difficult to functionalize [...]
A novel approach to the problem of identification of failed integrated circuits (ICs) on electronic circuit boards has been sought that would allow for drastically reducing the costs of the test equipment development and maintenance. [...]
Molecular dynamics simulation is performed on the buckling behavior of single and multi-walled carbon nanotubes under axial compression. Brenners second generation empirical potential is used to describe the many-body short range interatomic interactions for single-walled [...]
The electrochemical hydrogenation property of carbon nanotubes (CNTs) was investigated. A slurry consisting of CNTs and a binder was pasted on a Ni foam to form an electrode. The discharge capacity was tested in an [...]
Five stable C70 fullerene dimers with [2+2] bridges between hexagon-hexagon bonds, which are experimentally characterized very recently, have been investigated by several semi-empirical approaches and ab initio Hartree-Fock self-consistent field calculation and hybrid density functional [...]
Sensitive and selective ascorbic acid biosensors were developed for the determination of ascorbic acid (AA) based on glassy carbon electrode (GCE) coated with a thin multi-wall carbon nanotube (MWNT) film. The MWNT film showed excellent [...]
Noise can help signal detection at the nano-level. Experiments on a single-walled carbon nanotube transistor confirm that a threshold is sufficient for a nondynamical system to exhibit stochastic resonance: a judicious amount of noise can [...]
