Furthermore, since dyes molecules were insoluble, it is indicated that the EPS produced by the fungal myceliamight have a nonpolar molecule. These results were considered very important and under investigation in our laboratory.
Propane is a nonpolar molecule. In contrast, water is a polar molecule.
What if we could induce polarity in a nonpolar molecule? Jeesperse CPW uses sodium polyacrylate to induce polarity in a wax.
The possible reason may be that there are no strong intermolecular forces between DMSO and TMB because 1,3,5-TMB is a symmetrical nonpolar molecule. Conversely, stronger forces exists for the systems with 1,2,4-TMB, so the values are positive.
But it can't cling to lipids, which are nonpolar molecules. That's why water and oil, a nonpolar molecule, don't mix.
Sunflower oil contains linoleic acid, while jatropha curcas oil contains oleic acid, and both these acids are classified as nonpolar molecules. The attractive force between nonpolar molecules is caused by a temporary dipole, causing the force to be very weak.
The word hydrophobic literally means "water-fearing" and it describes the segregation of water and nonpolar substances, which allows maximizing hydrogen bonding between molecules of water and minimizing the area of contact between water and nonpolar molecules. A super hydrophobic coating is a nanoscopic surface layer that repels water.
For these reasons, the solubility and diffusivity of nonpolar molecules such as mineral oils is low.
Second, both barrier and resistance properties to polar and nonpolar molecules cannot be simultaneously improved.
The energy liberated due to the interaction between polar and nonpolar molecules of protein with blood water at a certain temperature might be the origin of dipolar polarization.
The specific surface area of soils should preferably be measured by sorption of polar molecules, since nonpolar molecules, such as nitrogen gas ([N.sub.2]), cannot penetrate internal surfaces and small pores that are blocked by organic matter (Newman 1983; Pennell et al.
Naturally, polar molecules and nonpolar molecules would act differently with respect to electric fields.
