nonpolar

 [non-po´lar]
not having poles; not exhibiting dipole characteristics.

nonpolar

Of a molecule or molecular region in which the chemical bonds share electrons equally so that there are no externally operative electric charges.

nonpolar

(of a substance) bearing no charge or hydroxyl groups, and thus not combining with water.

For the case of MT filling with air, this value is equal to the working capacitance of the MT in air C = [C.sub.air]; for the case of MT filling with a dehydrated liquid nonpolar dielectric C = [[epsilon].sub.nld] x [C.sub.air]; for the case of filling the API with the emulsion investigated C = [[epsilon].sub.eml] x [C.sub.air].

For a nonpolar polymer dissolving into a nonpolar solvent, the situation where [DELTA][H.sub.m] [greater than or equal to] 0 and [DELTA][S.sub.m] > 0 can only occur when T is high enough to facilitate [DELTA][H.sub.m] < T[DELTA][S.sub.m].
It has been called everything from unipolar to multipolar to nonpolar and now, because of the rivalry between the United States and China, bipolar.
The mesogens are a nonpolar nematic with a methoxy (OCH3) end group and a polar nematic with a cyano (CN) end group [10].
These methods are called "noncovalent" (the surface chemistry of the CNTs is not altered), and CNTs may be bonded to the polymer through nonpolar types of interaction like [pi]-stacking, provided that the polymer has conjugated double bonds or heteroatoms with nonbonding electron pairs [22].
Atoms of very similar electronegativity (less than ~0.5) share electron pairs evenly and form nonpolar covalent bonds, such as carbon and hydrogen, whereas atoms with greater (0.5-2) electronegativity differences form polar covalent bonds, with the bonds being more polar the greater the electronegativity differences.
