On the micellar aggregates of alkali metal salts of deoxycholic acid
Article Abstract:
Similar unit cell constants and 8/1 helices were used to closely monitor x-ray diffraction patterns of sodium deoxycholate (NaDC) and rubidium deoxycholate (RbDC). X-ray patterns of lithium and potassium deoxychlate fibers extracted from aqueous micellar solutions were represented by trimer-formed 8/1 helices. The trend of the average electric dipole moment mu of a NaDC monomer was known through dielectric measurements. It has been discovered that the dipole moment values decrease when the size of the NaDC micellar aggregates agree with the presence of the helices.

An integrated study of small-angle X-ray scattering and dynamic light scattering on cylindrical micelles of sodium glycodeoxycholate
Article Abstract:
A study of small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS) measurements on aqueous micellar solutions of the ionic biological detergent sodium glycodeoxycholate (NaGDC) is reported. The comparison between SAXS and DLS measurements revealed that in NaGDC micellar solutions the effect of double layer electric repulsion, which prevails at low ionic strength, is lowered because of the screening effect by increasing the electrolyte concentration.

Study of intermicellar interactions and micellar sizes in ionic micelle solutions by comparing collective diffusion and self-diffusion coefficients
Article Abstract:
The experimental collective and self-diffusion coefficients of micelle solutions can be satisfactorily interpreted on the basis of the DLVO theory of colloid stability. The interpretation method was analyzed by considering the effect of micellar growth and interaction potential variation.
