The global reactivity indices (electronic chemical potential [mu], chemical hardness [eta], global electrophilicity [omega], global nucleophilicity N) were estimated according to the equations recommended by Parr [15, 16] and Domingo [17, 18].
The solution consisting of solvent molecules and polymer chains is characterized primarily by the interaction parameter [chi] which is related to the enthalpy of a polymer mixing with a solvent, dynamic viscosities [eta], conductivities s, surface tensions [gamma], temperatures [T.sub.L] and chemical potentials of both components (solvent [[micro].sub.SOL] and polymer Ppol).
As described earlier in this article, the driving force of water absorption of water swellables is the chemical potential difference between swellable elastomer and surrounding fluid.
Nextly, the atom chemical potentials of Ti and O must satisfy the boundary conditions [mu](O) [less than or equal to] 1/2 [mu]([O.sub.2]) and [mu](Ti) [less than or equal to] [mu](Ti metal), where [mu]([O.sub.2]) and [mu](Ti metal) are the chemical potentials of oxygen gas and titanium metal, respectively.
At the frequency ranges of THz and far-infrared, the dissipative loss of graphene is less than the usual metals and its optical response is described by the surface conductivity which is related to its chemical potential and can be controlled and tuned by voltage or chemical doping [16-18].
The Fischer-Tropsch process operates at elevated pressures; the ideal gas model for chemical potential is not expected to be valid.
The dynamic chemical potentials [mu] of G are those chemical potentials [[mu].sup.*] = [mu] of the open controlling reservoir [G.sup.*] of [T.sup.*] = [THETA] for which all mole number rates [[??].sup.*] vanish with the change of sign.
We have tabulated above the different values of chemical potentials obtained in our previous papers [1,13-17] for different center-of-mass energies, as shown in Table 1, by using our unified statistical thermal freeze-out model.
Because Flory's original article [30] is for a binary diluted system, we used the equations for the calculation of chemical potentials given by Young et al.
where [[mu].sup.r.sub.i], [[mu].sup.r.sub.i-1] and [[mu].sup.r.sub.1] are respectively residual chemical potentials of [A.sub.i], [A.sub.i-1] and [A.sub.1].
