|
Non-polar nitride can eliminate internal polarization fields because of the absence of spontaneous polarization in the non-polar materials. |
|
This assumption has been shown to hold for non-polar and slightly polar organic chemicals. |
|
Typically, hydrocarbon resins are non-polar, and thus highly compatible with non-polar rubbers and polymer. |
|
Another technology uses water based detergents to dissolve polar and non-polar soils. |

Naphthenic groups are, if not directly polar, at least less non-polar than the paraffinic groups. |
|
The breakdown of porphyrin yields bilirubin, a product that is non-polar and therefore, insoluble. |
|
In a 20 mL solution, addition of just ten drops of water was enough to produce a biphasic system composed of polar and non-polar layers. |
|
In addition, these films with two gloss surfaces have good resistance to weak acids and alkalis as well as to non-polar solvents. |
|
I plan to use this to emphasize polar and non-polar covalencies as a real-life application. |
|
Rubber-based adhesives normally have good adhesion to non-polar substrates such as untreated polyethylene and polypropylene. |
|
These layers use aqueous solvent systems to separate extremely non-polar substances and analyze particular polar substances that can adapt to ion-pair chromatography. |
|
Both non-polar and polar molecules may acquire a temporary induced dipole moment as a result of the influence of an electric field generated by a nearby ion or polar molecule. |
|
In this case, pollutant are non-polar, non-miscible with water and mainly oils. |
|
|
Note that the unbranched, long-chain nature of the alcohol and acid moieties give jojoba esters their non-polar behavior. |
|
This grade can be used with most esters and non-polar oils to obtain crystal clear gels. |
|
Polar extracts exhibited stronger activities than non-polar extracts. |
|
In contrast to NP, the retention time is longer for molecules which are non-polar in nature, allowing polar molecules to elute more rapidly. |
|
It is a fundamental rule of chemistry that polar and non-polar molecules do not mix to form a solution. |
|
Moreover, these radicals can affect the material's catalytic capacities and physically obstruct the adsorption of non-polar molecules. |
|
When a non-polar molecule is brought near to the polar molecule, the positive end of the polar molecule attracts the mobile electrons of non-polar molecules. |
|
Chlorobenzenes have toxicity of non-polar narcosis. |
|
The breathtaking landscapes of the Alsek River valley provide views of Canada's highest mountains, and glaciers flowing from the largest non-polar icefield in the world. |
|
The problem facing the medical sector is consists of ensuring a finish exempt of pollutants, like mineral based cutting oils or non-polar, like metal particles or salts for example. |
|
Usual type of widely accepted structure of cell membrane is fluid mosaic model with outward and inward projection of polar heads and non-polar heads with several embedded globular proteins. |
