The Growth Process of Nanotubes in Nanotubes

AIP Conference Proceedings, 2004
We have investigated the growth process of carbon nanotubes in carbon nanotubes as a function of anihilation temperature and duration. Raman spectroscopy is applied to characterize the produced DWCNTs. The RBM scales as l/d and renders the very narrow new inner CNTs easily detectable.

Carbon Nanotubes

2017
Carbon nanotubes (CNTs) are remarkable objects that once looked set to revolutionize the technological landscape in the near future. Since the 1990s and for twenty years thereafter, it was repeatedly claimed that tomorrow’s society would be shaped by nanotube applications, just as silicon-based technologies dominate society today.

Nanotube–nanotube transformation synthesis and electrochemistry of crystalline CuAgSe nanotubes

Journal of Crystal Growth, 2009
Ortho-CuAgSe nanotubes were facilely synthesized through a nanotube–nanotube transformation process in aqueous solution at room temperature. The products as-obtained were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), X-ray photoelectron spectra (XPS) and thermogravimetric (TG ...

Nanotubes in biosensing

WIREs Nanomedicine and Nanobiotechnology, 2010
AbstractCarbon nanotubes (CNTs) have extensively been used for electrochemical and optical biosensing due to the unique mechanical, chemical, and electrical properties. This review introduces two functionalization categories, noncovalent interaction along the CNTs sidewalls via physical adsorption or entrapment and covalent binding via carboxylate ...

Aligned Nanotubes

ChemPhysChem, 2003
AbstractSince the discovery of carbon nanotubes by Iijima in 1991, various carbon nanotubes with either a single‐ or multilayered graphene cylinder(s) have been produced, along with their noncarbon counterparts (for example, inorganic and polymer nanotubes).

He atoms in carbon nanotubes and nanotube bundles

Physical Review B, 2004
We report results for the energetics and single-particle spectra of $^4$He and $^3$He atom confined by one, two, and three carbon nanotubes, obtained using both a smooth--tube model for the interaction between helium atoms and tubes, and a realistic model that takes the atomic structure of the tubes into account.

Thermal conductivity in nanotubes and nanotube bundles

2005
Nanotubes show a very interesting behaviour of lattice thermal conductivity depending on the tube diameter, with very high thermal conductivities for small diameters. In bundles of nanotubes, the thermal conductivity is affected by the reduced dimensionality of the phonon system.

Perspective of nanotube sensors and nanotube actuators

4th IEEE Conference on Nanotechnology, 2004., 2005
The state of the art of nanotube sensors and nanotube actuators are overviewed according to the physical properties/effects (large aspect ratio, ultra-high elasticity, lower onset field emission, ultra-small interlayer friction, etc.) applied, number of nanotubes (single, double or multiple-array, fiber, film and bulk) involved, and configurations of ...
