    • Cylindrical micelles are structures at thermodynamic equilibrium. In principles, the surfactants dissolve without heating. However, since dissolution is often very slow, the mixtures are heated at a temperature which do not result in surfactant degradation.

    • note
    • Due to its viscoelastic behavior, the solution of entangled cynlindrical micelles exhibits a positive normal force difference in the direction perpendicular to the shear direction, as is the case in many viscoelastic fluids. This normal force is due to the strong orientation of the micelles parallel to the velocity direction.

    • note
    • For both steric and eletrostatic reasons, gauche conformations about the central C-C spacer bond are unlikely. On the other hand, bonds adjacent to the nitrogens always have gauched conformations.

    • note
    • This equation has been derived for isotropic motions and is valid provided that the correlation time for a given diffusive motion is much smaller than the time frame of the entire molecular dynamics calculation. In the present case, we are well within the limits of validity.
