In addition to the classification by particle size, dispersions can also be labeled by the combination of the dispersed phase and the medium phase that the particles are suspended in. Aerosols are liquids dispersed in a gas, sols are solids in liquids, emulsions are liquids dispersed in liquids (more specifically a … See more A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. The two phases may be in the same or different states of matter. Dispersions are … See more The term dispersion also refers to the physical property of the degree to which particles clump together into agglomerates or aggregates. While the two terms are often used interchangeably, according to ISO nanotechnology definitions, an agglomerate is … See more Milk is a commonly cited example of an emulsion, a specific type of dispersion of one liquid into another liquid where to two liquids are immiscible. The fat molecules suspended in milk provide a mode of delivery of important fat-soluble vitamins and nutrients from … See more Dispersions do not display any structure; i.e., the particles (or in case of emulsions: droplets) dispersed in the liquid or solid matrix (the "dispersion medium") are assumed to be … See more Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of … See more A solution describes a homogeneous mixture where the dispersed particles will not settle if the solution is left undisturbed for a prolonged … See more WebFeb 19, 2015 · The merits of liquid sample dispersion Liquid sample dispersion is a gentle and effective sample preparation method for particle size analysis, especially when handling materials that are very fine (less than 20 μm in size) or are sticky/cohesive.
