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

Sensitive recognition of Shiga toxin using biosensor technology: An efficient platform towards bioanalysis of pathogenic bacterial
TL;DR: In this paper, the role of various labels in the biosensing of Shiga toxin was investigated using various labelled and label-free methods, and the importance of various bioreceptors (electrical, optical, electrochemical, electrochemiluminescence, and photoelectrochemical) conjugation with advanced nanomaterials were studied and compared, critically.

Heating causes non-linear microwave absorption anomaly in single wall carbon nanotubes
TL;DR: In this article, the authors investigated the nature of the absorption anomaly in single wall carbon nanotubes at low temperatures (below $20$ K) using a time resolved microwave impedance measurement technique and proved that the anomaly has an extremely slow, a few hundred second long dynamics.

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.
