Query: Towards quantification of the ratio of the single and double wall carbon
  nanotubes in their mixtures:An In situ Raman spectroelectrochemical study   Mixtures containing different weight ratios of single wall carbon nanotubes
(SWCNT) and double wall carbon nanotubes (DWCNT) were prepared and studied by
in-situ Raman spectroelectrochemistry. Two components of the G-prime mode in
the Raman spectra, which can be resolved at high electrode potentials, were
assigned to the signals from inner tubes of DWCNT and outer tubes of DWCNT
together with SWCNT. The dependence of the ratios of these two components of
the G-prime mode on the nominal amount of SWCNT and DWCNT in the samples was
simulated so that the residual amount of SWCNT in the original DWCNT could be
determined. Additionally, the individual contributions of all components of
carbon nanotubes into the total area of the G-prime mode at high electrode
potentials were estimated from the simulation.
