Raman studies on double-wall carbon nanotubes (DWCNTs) obtained from peapods showed that the radial breathing mode (RBM) response of the inner tubes is split into more components than there are geometrically possible inner tubes. This was attributed to the possibility that one inner tube type may form in more than one outer tube type. Recent resonance Raman investigations revealed an even more ...
Corrigendum: Mixed convection of functionalized DWCNT-water nanofluid in baffled lid-driven cavities
is paper reports the strain sensitivity of �exible, electrically conductive, and nanostructured cellulose which was prepared by modi�cation of bacterial cellulose with double-walled carbon nanotubes (DWCNTs) and multiwalled carbon nanotubes (MWCNTs).e electrical conductivity depends on themodifying agent and its dispersion process.e conductivity of the samples obtained from bacterial cellulo...
The electronic properties of multi-walled carbon nanotubes (MWCNTs) depend on the positions of their walls with respect to neighboring shells. This fact can enable several applications of MWCNTs as nano-electromechanical systems (NEMS). In this article, we report the findings of a first-principles study on the stability and dynamics of point defects in double-walled carbon nanotubes (DWCNTs) an...
The temperature dependence of optical excitation lifetime 1/ and transition energies Eii were measured for bucky papers of single-wall carbon nanotubes SWCNTs and inner tubes in double-wall carbon nanotubes DWCNTs using resonant Raman scattering on the radial breathing mode. The temperature dependence of and Eii is the same for both types of samples and is independent of tube chirality. The dat...
S1. Translational motion of 1D sulfur chains inside SWCNT Fig. S1 shows the observed translational motion of encapsulated sulfur chains during the HRTEM measurements. In the initial stage of the HRTEM observation, we find two lines inside the nanotube that extend across the entire SWCNT length (Fig. S1A). In subsequent observations taken several tens of seconds later (Fig. S1B), the length of t...
Dual-wavelength mode-locked Yb:LuYSiO5 laser with a double-walled carbon nanotube saturable absorber
We report a passively dual-wavelength mode-locked Yb:LuYSiO5 (Yb:LYSO) laser with a double-walled carbon nanotube saturable absorber (DWCNT-SA) for the first time. Simultaneous mode-locking at the 1045.5 and 1059.0 nm was achieved and the pulse duration of the dual-wavelength modelocked pulses are 8.0 ps. Ultrahigh repetition rate ultrafast pulses with 750 fs pulse width and 3.66 THz repetition...
Keywords: Free transverse vibration Vibration mode shapes Double-walled carbon nanotubes (DWCNTs) Nonlocal Rayleigh beam theory Reproducing kernel particle method (RKPM) a b s t r a c t The true understanding of free vibration of double-walled carbon nanotubes (DWCNTs) plays a vital role in optimal design and dynamic control of such nanostructures. This paper is aimed to examine free flexural v...
