Here, we report a simple method to grow thin MoS2 nanosheets (NSs) on the ultralong nitrogen-doped carbon nanotubes through anion-exchange reaction. The MoS2 NSs are grown on ultralong nitrogen-doped carbon nanotube surfaces, leading to an interesting ...

Biexcitons in Carbon Nanotubes
Fullerenes, Nanotubes and Carbon Nanostructures, 2005Abstract One‐dimensional confinement in carbon nanotubes leads to pronounced excitonic effects. With recent advances in ultrafast optical spectroscopy on isolated nanotubes, multi‐photon excitations such as biexcitons become accessible. Using an effective‐mass model of such excitations we predict that stable biexcitons will be found in all ...

physica status solidi (b), 2006
AbstractWe present two‐photon excitation luminescence experiments on carbon nanotubes which show the excitonic origin of the optical excitations. The two‐photon allowed exciton state, which has even parity under rotation about the U‐axis, is roughly 300 meV above the one‐photon active, odd‐parity state.

Polymer Nanocomposites Containing Carbon Nanotubes
, 2006We review the present state of polymer nanocomposites research in which the fillers are single-wall or multiwall carbon nanotubes. By way of background we provide a brief synopsis about carbon nanotube materials and their suspensions.

Properties of Carbon Nanotubes
2014Carbon nanotubes are certainly the most studied nanomaterials ever, considering the cumulated number of papers devoted to them since the 1990s (Fig. 1.1). Only graphene will possibly overcome nanotubes in this regard one day, specifically because of the boosting effect of the Nobel Prize dedicated to it in 2010.

Hemotoxicity of carbon nanotubes
Advanced Drug Delivery Reviews, 2013Carbon nanotubes may enter into the bloodstream and interact with blood components indirectly via translocation following unintended exposure or directly after an intended administration for biomedical purposes. Once introduced into systemic circulation, nanotubes will encounter various proteins, biomolecules or cells which have specific roles in the ...

Tensile loading of ropes of single wall carbon nanotubes and their mechanical properties
Physical Review Letters, 2000The mechanical response of 15 single wall carbon nanotube (SWCNT) ropes under tensile load was measured. For 8 of these ropes strain data were obtained and they broke at strain values of 5.3% or lower.

Extreme oxygen sensitivity of electronic properties of carbon nanotubes
Science, 2000The electronic properties of single-walled carbon nanotubes are shown here to be extremely sensitive to the chemical environment. Exposure to air or oxygen dramatically influences the nanotubes' electrical resistance, thermoelectric power, and local ...
