Mutual mixing

A flow pattern in which the various fluid elements follow different paths without mutual mixing on a microscopic scale. An example of this case is laminar flow. 

Attractive forces between nonpolar molecules such as mineral oil and n-hexane are very weak. Therefore, such molecules can mutually mix and solution is easy. The attractive forces between polar HjO or C H OH molecules are strong H-bonds. Most nonpolar molecules cannot overcome these H-bonds and therefore do not dissolve in such polar protic solvents.

The carbonaceous moiety and a binder are mutually mixed in a ratio typically based on empirical experience [5,7,9,16,38-41,50-52,58] the optimal carbon-to-pasting liquid ratio for traditional carbon pastes usually being 1.0 g 0.5 ml. The two main components are usually hand-mixed in a mortar using a pestle with sufficient pressure, and advisably in two or three consecutive steps, when the formed mass is ripped off from the vessel wall to the bottom and homogenized... 

Mutual mixing of two ILs might show fascinating properties. Low concentration (0.3 mM) of IL-1 was found to produce a striking effect on IL-2. In the / versus log [IL-2] dependence, a CMC-like inflection of IL-2 was observed at a very low concentration of 0.1 pM at 298 K in aqueous medimn, the CMC of IL-2 was foimd to be 0.03 mM. There were reports of CMC decrease on mntnal interaction between two ILs [29] interaction in the IL-2/IL-1 combination herein fonnd was conspicuons (Fig. 10.1a, inset A). Tensiometric results of CMCs of mixed micelles were tested against Clint s ideal mixed micelle formation model. 

By negligible volume changes due to mutual mixing of the monomers 1 and 2 in the droplet phase and by mixing the monomers 1 and 2 with the polymer phase in the particles. Equation 4.12 can be rewritten in concentrations or mole fractions ...
