Distributed dispersion

Therefore, the velocities of liquid are consistent with the velocities of particles, that is, the motion of nano-particles can reflect the flow of liquid verily in the given condition. Figures 39 and 40 show the comparison of the two liquid samples with different mass concentration of the nanoparticles at different flow rates. Generally, particle velocity increases synchronously with the liquid flow rate, but the velocity becomes dispersive when it exceeds 300 /u,L/min. The more the particles were added in the liquid, the more dispersive of the velocities of the particles were observed. Several possible causes can result in this phenomenon. One possible reason is that when the velocity of flow becomes large enough, the bigger particles in the liquid cannot follow the flow as the smaller particles do, or bigger particles will move slower than the liquid around them, so the velocities of particles will distribute dispersedly. Another possible reason is that when the velocity of flow increases the time for particles to traverse, the view field of the microscope will decrease. As a result, the number of data points in the trace of a particle...

The optical properties of semiconductor QDs (Fig. la-c, Tables 1 and 2) are controlled by the particle size, size distribution (dispersity), constituent material, shape, and surface chemistry. Accordingly, their physico-chemical properties depend to a considerable degree on particle synthesis and surface modification. Typical diameters of QDs range between 1 and 6 nm. The most prominent optical features of QDs are an absorption that gradually increases toward shorter...

Oil and water do not mix. On many occasions, however, we want them to mix. This is accomplished by emulsification. An emulsion is a dispersion of two immiscible liquids. One phase is the dispersing agent and is called the external, outer, or continuous phase. At least one further phase is finely distributed (disperse phase). It is also called the inner or internal phase. Emulsions are of fundamental importance in many applications and various fields of science and technology such as oil recovery and the production of creams for the pharmaceutical and cosmetic industry. In cooking and in food industry emulsions have numerous uses in products such as margarines, soups, sauces, chocolate drinks, etc. [536,537]. 

In this context, modern geographical information systems (GIS) represent an indispensable tool for better understanding the distribution, dispersion and interaction processes of some toxic and potentially toxic elements. Discussion on the use of GIS in the urban environment is, therefore, also provided.

Mixing requirements for polymer compounding can be divided into two basic disciplines—dispersive and distributive. Dispersive mixing breaks down a particle into smaller units, while distributive mixing homogenizes the spatial relationship of the particles (whether dispersed or not). 

In these two equations r/ad, is the viscosity of the adsorbed polymer, >i2e the (non-equilibrium) excess interfacial tension and y,2 the (equilibrium) interfacia] tension, so that the quotient yi2j i2 describes the distance of the thermodynamic system from the equilibrium state. It is ea.sy to see that such behaviour is not at all in accordance with the idea of statistically distributed dispersed phases and non-interacting interfaces.

COj Nj Cj—Cj in the coalfield. Nj—CH4 is distributed widely in coal seam NO. 1, which accounted for about 85% of coal seam mining field. CH4 is mainly distributed near F, fault and the south west of X line, that is those local areas which are anticline NO. 1 and NO. 3, syncline axis NO. 2. N, and Nj—COj—CFI4 are distributed dispersedly. On average, heavy hydrocarbon is accounted for 7.33% of total gas. Nj —CH4 is distributed widely in the coal seam N0.3, which is accounted for 90% of coalfield. CH4 accounted for about 1% of the mining field, which is mainly distributed near Fj fault local areas.

Implementation of the novel properties of nanocomposites strongly depends on processing methods that lead to controlled particle size distribution, dispersion, and interfacial interactions. Processing technologies for nanocomposites are different from those for composites with micrometer-scale fillers, and new developments in nanocomposite processing are among the reasons for their recent success.

Mixing and solids distribution. Dispersion coefficients of gas, liquid and solid phase have not been measured under conditions prevailing in the FTS. However, the liquid phase dispersion coefficient depends only slightly on liquid phase properties. It is therefore believed that correlations based on a lot of data for low viscous media and from coliomns of various sizes can be applied. Such a correlation was given by Deckwer et al. (68)...
