Abstract

The diversity of regulatory mechanisms and forms of governance are discussed in the context of the implementation of the 'creative cities' project worldwide. Tentative typologies of case studies and governance mechanisms are drawn to build information on 'creative cities' governance models.

4. Bulk structure of the (inverted) sponge phase of the lytropic mixture of sodium dodecyl sulfate, 1-pentanol, water, and cyclohexane

Abstract

Different techniques are used to characterize the structure of the sponge (L3) phase in the bulk of the partial isothermal surface of the phase diagram of the sodium dodecyl sulfate/ 1-pentanol/ cyclohexane (C6)/ and water mixture. A water layer of thickness delta separates two nonconnected regions in C6.

5. Tetragonal structure induced by wetting at the interface between a solid substrate and a lyotropic sponge phase

Author

Magalhaes, M., Neto, A.M. Figueiredo, Barbero, G., and Tromba, A.C.

Subjects

Abstract

The wetting of a substrate by a lyotropic sponge phase is studied by using grazing X-ray scattering and optical microscopy. The wetting promotes the formation of an anisotropic layer with tetragonal symmetry on a length scale of ~10 nm on the substrate. It is also identifies the surface field with one due to the selective ionic adsorption as the candidate responsible for the observed change of structure from melted cubic to tetragonal.
