The Ag 1-D nanostructure is covered by CTAB micelle. I want to know what is the thickness of the CTAB micelle, or CTAB 3-D structure size. As shown in the schematic diagram. Thanks.
In the 1-D nanostructure (thickness) you have two molecules СTAB (without water). therefore, you need to know the length of the СTAB molecule. How to define it, you can find in our article.

To determine the 3-D structure (layer size) you need to know the area per CTAB molecule. You can find out about it in the responses of the RG.

X-rays alone are maybe not enough. A combination with small angle neutron scattering will give the complete information. This was shown in a work by Olivier Spalla and co-workers (Langmuir, doi: 10.1021/la203451p). In addition the length of the surfactant molecule can be estimated by some simple approximations ( see Tanford formula)
By discussing the structure of micelles, I add the duality of the micelle structure of ionic surfactants.
