    • Assuming that the overall concentration of CTAB molecules is quite similar in the upper and lower phase, and that about 5% of the CTAB molecules are adsorbed onto the carbonaceous species (in accordance with previous studies (C. Richard, F. Balavoine, P. Schultz, T.W. Ebbesen, C. Mioskowski Science 2003, 300, 775) the effective concentration of the free CTAB micelles in the lower phase may be lower by about 0.5 wt, as compared to the upper phase
