  2. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    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 the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. [4]

  3. Optical properties - Wikipedia

    en.wikipedia.org/wiki/Optical_properties

    The optical properties of a material define how it interacts with light. The optical properties of matter are studied in optical physics (a subfield of optics) and applied in materials science. The optical properties of matter include: Refractive index; Dispersion; Transmittance and Transmission coefficient; Absorption; Scattering; Turbidity

  4. Dispersion - Wikipedia

    en.wikipedia.org/wiki/Dispersion

    Dispersion (chemistry), a system in which particles are dispersed in a continuous phase of a different composition; Dispersion (geology), a process whereby sodic soil disperses when exposed to water; Dispersion (materials science), the fraction of atoms of a material exposed to the surface; Dispersion polymerization, a polymerization process

  5. Dispersion (optics) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(optics)

    Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency. [1] Sometimes the term chromatic dispersion is used to refer to optics specifically, as opposed to wave propagation in general. A medium having this common property may be termed a dispersive medium.

  6. Dispersion (materials science) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(materials_science)

    In materials science, dispersion is the fraction of atoms of a material exposed to the surface. In general, D = N S / N , where D is the dispersion, N S is the number of surface atoms and N T is the total number of atoms of the material. [ 1 ]

  7. Diffusion - Wikipedia

    en.wikipedia.org/wiki/Diffusion

    The concept of diffusion is widely used in many fields, including physics (particle diffusion), chemistry, biology, sociology, economics, statistics, data science, and finance (diffusion of people, ideas, data and price values). The central idea of diffusion, however, is common to all of these: a substance or collection undergoing diffusion ...

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  9. Dispersion polymerization - Wikipedia

    en.wikipedia.org/wiki/Dispersion_polymerization

    In polymer science, dispersion polymerization is a heterogeneous polymerization process carried out in the presence of a polymeric stabilizer in the reaction medium. . Dispersion polymerization is a type of precipitation polymerization, meaning the solvent selected as the reaction medium is a good solvent for the monomer and the initiator, but is a non-solvent for the po
