Abstract:
A method for selecting an operative component to combine first and second immiscible phases includes selecting a first operative component and computing the value of the free energy of mixing for it and the first and second immiscible phases. If the computed free energy is greater than zero, the sigma profile of the first candidate is mutated to define a hypothetical sigma profile of a candidate substitute operative component. The free energy of mixing for the substitute and the first and second immiscible phases is computed. The mutation and computation are repeated for a predetermined number of repetitions or until the free energy of the candidate substitute component and the first and second phases is less than zero, whichever first occurs. A material exhibiting a sigma profile corresponding to that of the candidate substitute producing a free energy of solvation less than zero is selected.
