    Notes: Summary Both linear and non-linear viscoelasticity experiments have been performed in semi-dilute micellar aqueous solutions of ethanediyl-α,ω-bis (dodecylmethylammonium bromide) as a function of solution chloride (NaCl) concentration. The results suggest that both linear and non-linear properties are affected by the electrostatic interactions. In particular, the plateau modulusG′∞ and the ratioσ m/G′∞, whereσ m represents the plateau value in a stress-shear rate experiment, are enhanced as the electrostatic interactions are screened by addition of salt. The zero-shear viscosity is lowered upon addition of NaCl, due likely to an exchange of the Cl− ions with the Br− counterions.

    Notes: Abstract Colloidal dispersions in hydrocarbons of lead and calcium salts of isooctanoic acids are studied by means of Transmission Electron Microscopy and Light Scattering. The complementary results obtained, using each technique, allow us to investigate the structure of the mineral core, the size and the morphology of the colloidal particles. Special attention is paid to the aggregation properties of the metal salts particles as a function of the dilution and solvent.
