The calculations performed with two theoretical models, B3LYP-D2 and M05-2X, in polar and nonpolar solvents
, proved to be in good accordance.
c) Nonpolar solvent
, hexane, when eluted first pushes only edible oil leaving curcumin and related curcumin compounds at their origin.
It is scattered and mostly limited to mixtures of nonpolar solvents
As a result, the apparent activity coefficient of the monomer species will be greater than one when the pure solvent is diluted into another nonpolar solvent
The conditions for this to occur appear to be either plasticizing the matrix with an appropriate nonpolar solvent
, or heating the membrane above [T.sub.g,m].
low moisture and water vapor permeability, and excellent chemical resistance against polar solvents and solutions including acids, bases, esters, and alcohols but only moderate heat resistance and poor chemical resistance against nonpolar solvents
like alkanes, ethers, and oils.
Unlike silicone, fluorosilicone contains tri-fluoropropyl groups that enhance its chemical resistance to nonpolar solvents
, fuels, oils, acids and alkaline chemicals at temperatures between -70[degrees]F and 450[degrees]F.
Schoonheydt and Johnston  reported that the absorption maxima of dye molecules in nonpolar solvents
adsorbed onto the surface of clay minerals could shift to shorter wavelengths because the solvent-molecule interaction was stronger in the ground state than in the excited state.
The Si-NPs exhibit good luminescence spectra in some nonpolar solvents
but its stability is very limited .
