Thermal conductance and thermopower of an individual single-wall carbon nanotube.
TLDR
It is observed that the thermal conductance of a 2.76-microm-long individual suspended single-wall carbon nanotube (SWCNT) was very close to the calculated ballistic thermal conductances of a 1-nm-diameter SWCNT without showing signatures of phonon-phonon Umklapp scattering for temperatures between 110 and 300 K.Abstract:
We have observed experimentally that the thermal conductance of a 2.76-μm-long individual suspended single-wall carbon nanotube (SWCNT) was very close to the calculated ballistic thermal conductance of a 1-nm-diameter SWCNT without showing signatures of phonon−phonon Umklapp scattering for temperatures between 110 and 300 K. Although the observed thermopower of the SWCNT can be attributed to a linear diffusion contribution and a constant phonon drag effect, there could be an additional contact effect.read more

TL;DR: In this paper, hollow carbon nanotubes (CNTs) were impregnated with an ionic liquid, resulting in a composite core-shell nanostructure, which was verified by transmission electron microscopy and rigorous observations revealed that the nanocomposite is stable, i.e., liquid did not evaporate owing to its low vapor pressure.

TL;DR: Thermal transport at carbon nanotube (CNT) interfaces was investigated by characterizing the interfacial thermal conductance between metallic or semiconducting CNTs and three different surfactants, and it was found that the semiconductor CNT's unexpectedly exhibited a higher conductance than that of metallic C NTs.

Unusually High Thermal Conductivity of Carbon Nanotubes
TL;DR: An unusually high value, lambda approximately 6600 W/m K, is suggested for an isolated (10,10) nanotube at room temperature, comparable to the thermal conductivity of a hypothetical isolated graphene monolayer or diamond.

Extreme oxygen sensitivity of electronic properties of carbon nanotubes
TL;DR: The results, although demonstrating that nanotubes could find use as sensitive chemical gas sensors, likewise indicate that many supposedly intrinsic properties measured on as-prepared nanotube may be severely compromised by extrinsic air exposure effects.
