Carbon is an element with extremely versatile bonding properties and theoretical
calculations have suggested the possible existence of several hundred structural allotropes …

This article reviews recent advances on the use of Raman spectroscopy to study and
characterize carbon nanostructures. It starts with a brief survey of Raman spectroscopy of …

The control of the geometry of carbon nanotubes has a high potential for electro-optical
technology developments. We report here the use of a new spectroscopic signature for the …

In this paper we report the characterization of linear carbon chains encapsulated in
multiwalled carbon nanotubes by using Raman spectroscopy and transmission electron …

Double-and triple-walled carbon nanotubes (DWNTs and TWNTs) consist of coaxially-
nested two and three single-walled carbon nanotubes (SWNTs). They act as the geometrical …

High-pressure resonance Raman experiments were performed on linear carbon chains Cn
confined in double-wall carbon nanotubes (Cn@ DWCNT). Our results indicate that the …

Isolated linear carbon chains (LCCs) encapsulated by multiwalled carbon nanotubes are
studied under hydrostatic pressure (P) via resonance Raman scattering. The LCCs' …

Pressure and temperature phase transitions of nanomaterials often differ significantly from
those of their bulk parents, offering novel approaches for the engineering of original …

The radial stability and the irreversible transformation of triple-wall carbon nanotubes
(TWCNTs) bundles are investigated at high pressure conditions both experimentally and …

In this work, we explain the origin and the mechanism responsible for the strong
enhancement of the Raman signal of sulfur chains encapsulated by single-wall carbon …
