Résumé
A few examples of experimental studies of soft matter systems will be presented toillustrate some aspects of the personal and scientific journey of Isabelle Grillo. I have metIsabelle for the first time almost twenty-five years ago in the Bombannes school, and sincethen a combination of geographic coincidence, common scientific topics – from surfactantsystems to polymer nanocomposites -, and a shared interest in a technique, neutronscattering, made us walk some steps of this journey together. While the extra-ordinarystructure of many of the systems Isabelle took interest in will be presented by world-leadingexperts in this symposium, my presentation will shortly highlight vesicular structures, andthen bridge the gap between PhD work supervised by us on nanocomposites to our currentunderstanding of the structure of such nanomaterials.
