Reversed micelles in an "iso-density" solvent landscape: Pressure-Temperature studies

For micelles, can the solvent be treated as a benign medium, described by its density, or is it necessary to consider explicitly the solvent chemical identity and structure? The unique aspect of this proposal is the use of specialized sample environment, a temperature-pressure (T-P) cell, loaned from ILL as pre-agreed with ISIS and ILL instrument scientists. Using this cell, it will be uniquely possible to control thermodynamic conditions to achieve “iso-density” solvents (see Figures 1 and 3), and hence explore a previously inaccessible solvent landscape.
