Dispersive tendency

The dispersive tendency dominates in a high-temperature system containing only a few particles, while the order tendency is important in a system in which the particles are themselves ordered, as in a crystal or the DNA helix. The real states of systems of matter lie somewhere between these two extremes. 

These three herbs are cold in nature. They can strongly clear the heat at the Qi level and remove the heat-toxin. As they also have a dispersing tendency in action and can disperse the constrained heat and Qi, they can clear heat effectively. 

Qiao has a fragrant smell and thus has an ascending and dispersing tendency in action. As this moving tendency may reduce the chance of a constrained-heat condition forming, it is also used in the formula as a corrective assistant. 

These herbs are moist in nature and are particularly used for moistening the dryness of the intestines and treating mild constipation. Huo Ma Ren and Yu Li Ren are seeds and contain oil that can moisten the intestines and relieve the dryness. They are often used together to enhance each other s function. Xing Ren is the seed of apricot and has a similar function to the first two herbs. However, it also has a dispersing tendency. As it can ascend the Lung-Qi, it can activate Qi movement in the Large Intestine. 

The molecule He, is unknown since the number of antibonding electrons (2) is equal to the number of bonding electrons (2) and the net bond order is zero. With no bond energy14 to overcome the dispersive tendencies of entropy, two helium atoms in a "molecule will not remain together but fly apart. If it existed, molecular helium would have the electron configuration ... 

Beerbower and HiUs [21] considered the dispersing tendency on the oil and water interfaces of the surfactant or emulsifier in terms of the ratio of the cohesive energies of the mixtures of oil with the lipophilic portion of the surfactant and the water with the hydrophilic portion. For this, the Winsor concept was used, which is the ratio of the intermolecular attraction of oil molecules (O) and hpophihc portion of surfactant (L), Clq, to that of water (W) and hydrophihc portion (H),... 

Negative charge is widely dispersed, Tendency to become stable anion by I losing is very high. 

R = Ratio of dispersing tendencies on lipophilic and hydrophilic faces of C respectively. (The S-band ises m an as far as possible random arrangement of the hydrocarbon chains in the C and O sections all types of micelle.) From Winsor [174] with permission. 

The nonuniformity of drop dispersions can often be important in extraction. This nonuniformity can lead to axial variation of holdup in a column even though the flow rates and other conditions are held constant. For example, there is a tendency for the smallest drops to remain in a column longer than the larger ones, and thereby to accumulate and lead to a locali2ed increase in holdup. This phenomenon has been studied in reciprocating-plate columns (74). In the process of drop breakup, extremely small secondary drops are often formed (64). These drops, which may be only a few micrometers in diameter, can become entrained in the continuous phase when leaving the contactor. Entrainment can occur weU below the flooding point. 

Since polymer swelling is poor and the aqueous solubiUty of acrylonitrile is relatively high, the tendency for radical capture is limited. Consequentiy, the rate of particle nucleation is high throughout the course of the polymerization, and particle growth occurs predominantiy by a process of agglomeration of primary particles. Unlike emulsion particles of a readily swollen polymer, such as polystyrene, the acrylonitrile aqueous dispersion polymer particles are massive agglomerates of primary particles which are approximately 100 nm in diameter. 

In gas metal-arc, also called metal inert gas (MIG) welding, the arc is stmck between the workpiece and a metal electrode that is consumed as it is transferred in the form of molten droplets across the arc into the weld joint. Using a predominantiy argon shield gas, the droplets are transferred with Httie radial dispersion. Using pure helium, on the other hand, the droplets are larger and have more of a tendency to spray radially from the arc s axis. 

Additionally, mechanical (primarily shear), freeze—thaw, and thermal stabiHty the tendency to form sediment on long-term standing and compatibiHty with other dispersions, salts, surfactants, and pigments of acryHc dispersions are often evaluated. Details on the determination of the properties of emulsion polymers are available (60). 

The higher efficiency of fortified rosin sizes is beHeved to result from the semihydrophilic nature of the rosin adduct molecules, which results in a more dispersed system of particles during size precipitation by alum. Consequendy, there is a more uniform distribution of somewhat smaller particles on the sized fibers. This dispersing effect may result from the strong tendency of aluminum to coordinate with organic anions. 

Parallel Plate Viscometer. In parallel plate viscometers (164) the gap width usually is larger and can be varied freely. This is an advantage when measuring suspensions or dispersions with large particles or with a tendency to fly out of the gap. The wide gap means that there is less sensitivity to... 

Cationic starches show decreased gelatinization temperature range and increased hot paste viscosity. Pastes remain clear and fluid even at room temperatures and show no tendency to retrograde. This stabiUty is due to Coulombic repulsion between positively charged starch molecules in dispersion. 

At high relative humidities, adsorption is befleved to occur in response to a tendency for cellulose chains and lignin to disperse (solution tendency). Complete dispersion (dissolution) is prevented because of the strong interchain or interpolymer bonding at certain sites or regions. The differential heats of adsorption are much smaller than at low relative humidities. 

Iron. This is a specialty drier that is considered active at temperatures of about 130°C. For this reason iron 2-ethyIhexanoate [19583-54-1] is used in bake coatings that require maximum hardness. The principal drawback of using iron driers is that iron contributes a characteristic brownish red color to the coating and should only be used in dark pigmented systems. It has been reported that iron aids the dispersion of carbon black pigment and reduces the tendency for orange peel film defects (6).
