Typical intensity weighted distribution curves in the presence of different concentrations of surfactants; (a) CTAB, from top to bottom the concentrations are 0, 5, 10, 20, 60, 100, and 1000 μM; (b) TTAB, from top to bottom the concentrations are 0.05, 0.1, 0.3, 0.4, 0.5, and 2 mM; (c) DTAB, from top to bottom the concentrations are 0.5, 1, 2, 4, 6, and 8 mM; (d) OTAB, from top to bottom the concentrations are 0.5, 2, 3, 4, 6, and 9 mM.
