Raman hot spots. (Courtesy: University of Montreal/<i>Nature Photonics</i>) Tiny “tags” made of dye molecules stuffed into carbon nanotubes have been used to develop a high-resolution imaging ...

Carbon nanotubes (CNT) ... Raman spectra of graphene and carbon nanotube samples. The D, G, and 2D peaks are clearly visible in all three samples. The additional band observed at ~2205 cm-1 is due to ...

A new class of materials called Carbon NanoTubes (CNTs) has attracted significant interest for a wide range of engineering applications. These materials look similar to graphitic carbon in structure.

Although SERS studies have been done on carbon nanotubes, comparison of the Raman spectra of the CNTs and CNPs showed no changes suggesting a lack of SERS effects. To give a more ... 2000 Raman ...

We demonstrate cavity-enhanced Raman imaging to study individual single-walled carbon nanotubes (CNTs), a material with widespread applications in fields as diverse as electronics 15, photonics 16 ...

Albeit simple, a Raman spectrum of a carbon nanomaterial can offer a huge amount of information to characterize materials including graphene, carbon nanotubes, graphite, and carbon black. The i-Raman ...

Raman spectroscopy enables in situ monitoring of the electrical conductance of a single carbon nanotube. Carbon nanostructures such as carbon nanotubes are of interest because of their electronic ...

The nanotubes in these samples were then bundled to force interactions between individual nanotubes. To profile the carbon nanotube exciton energies, the team measured the intensity of Raman ...

Posted: May 12, 2009: Novel technique for real-time detection of carbon nanotubes in the body (Nanowerk Spotlight) New work at the University of Arkansas at Little Rock has, for the very first time, ...

The outer walls of both double- and triple-walled carbon nanotubes (CNTs) protect the innermost tubes from interacting with their environment. That is the key finding of a study by researchers in the ...
