BN domains included into carbon nanotubes: role of interface [PDF]
, 2009 We present a density functional theory study on the shape and arrangement of small BN domains embedded into single-walled carbon nanotubes. We show a strong tendency for the BN hexagons formation at the simultaneous inclusion of B and N atoms within the ...

Raman G and D band in strongly photoexcited carbon nanotubes [PDF]
, 2009 We observe clear differences in the spectral shift of the Raman D and G bands when heating double wall carbon nanotubes through intense photon irradiation and by varying the temperature in a thermostat.

Carbon Nanotube Salts. Arylation of Single-Wall Carbon Nanotubes [PDF]
Organic Letters, 2005 [reaction: see text] Carbon nanotube salts prepared by treating single-wall carbon nanotubes (SWNTs) with lithium in liquid ammonia react readily with aryl iodides to give SWNTs functionalized by aryl groups.

Stress distribution of carbon nanotube reinforced polymer matrix composites under tensile stress
Cailiao gongcheng, 2020 A cylindrical representative volume element model of polymer nano-composites reinforced by carbon nanotubes under a fixed tension stress was developed. The stress distribution in each layer of carbon nanotubes was numerically studied through developing a

A high precision method for length-based separation of carbon nanotubes using bio-conjugation, SDS-PAGE and silver staining. [PDF]
PLoS ONE, 2018 Parametric separation of carbon nanotubes, especially based on their length is a challenge for a number of nano-tech researchers. We demonstrate a method to combine bio-conjugation, SDS-PAGE, and silver staining in order to separate carbon nanotubes on ...

Van der Waals interactions of parallel and concentric nanotubes [PDF]
, 2002 For sparse materials like graphitic systems and carbon nanotubes the standard density functional theory (DFT) faces significant problems because it cannot accurately describe the van der Waals interactions that are essential to the carbon-nanostructure ...

Carbon Nanotube Flow Sensors [PDF]
Science, 2003 We report that the flow of a liquid on single-walled carbon nanotube bundles induces a voltage in the sample along the direction of the flow. The voltage that was produced fit a logarithmic velocity dependence over nearly six decades of velocity. The magnitude of the voltage depended sensitively on the ionic conductivity and on the polar nature of the ...

Thermal conductivity of deformed carbon nanotubes
, 2011 We investigate the thermal conductivity of four types of deformed carbon nanotubes by using the nonequilibrium molecular dynamics method. It is reported that various deformations have different influence on the thermal properties of carbon nanotubes. For

CCVD synthesis of carbon nanotubes from (Mg,Co,Mo)O catalysts: influence of the proportions of cobalt and molybdenum [PDF]
, 2004 Carbon nanotubes have been synthesised by catalytic chemical vapour deposition of a H2–CH4 mixture (18 mol% CH4) over (Mg,Co,Mo)O catalysts. The total amount of cobalt and molybdenum has been kept constant at 1 cat% and the proportion of molybdenum with ...
