  2. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    In addition, "uniform mixture" is another term for homogeneous mixture and "non-uniform mixture" is another term for heterogeneous mixture. These terms are derived from the idea that a homogeneous mixture has a uniform appearance , or only one phase , because the particles are evenly distributed.

  3. Dispersity - Wikipedia

    en.wikipedia.org/wiki/Dispersity

    In chemistry, the dispersity is a measure of the heterogeneity of sizes of molecules or particles in a mixture. A collection of objects is called uniform if the objects have the same size, shape, or mass. A sample of objects that have an inconsistent size, shape and mass distribution is called non-uniform.

  4. Homogeneity and heterogeneity - Wikipedia

    en.wikipedia.org/wiki/Homogeneity_and_heterogeneity

    Homogeneity and heterogeneity; only ' b ' is homogeneous Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image.A homogeneous feature is uniform in composition or character (i.e., color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous ...

  5. Dispersion (chemistry) - Wikipedia

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

    A colloid is a heterogeneous mixture where the dispersed particles have at least in one direction a dimension roughly between 1 nm and 1 μm or that in a system discontinuities are found at distances of that order. [8] A suspension is a heterogeneous dispersion of larger particles in a medium. Unlike solutions and colloids, if left undisturbed ...

  6. Molecular diffusion - Wikipedia

    en.wikipedia.org/wiki/Molecular_diffusion

    Diffusion is of fundamental importance in many disciplines of physics, chemistry, and biology. Some example applications of diffusion: Sintering to produce solid materials (powder metallurgy, production of ceramics) Chemical reactor design; Catalyst design in chemical industry; Steel can be diffused (e.g., with carbon or nitrogen) to modify its ...

    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 ...

  8. Polymer blend - Wikipedia

    en.wikipedia.org/wiki/Polymer_blend

    compatible polymer blends: Immiscible polymer blends that exhibit macroscopically uniform physical properties. The macroscopically uniform properties are usually caused by sufficiently strong interactions between the component polymers. [2] miscible polymer blends (homogeneous polymer blends): Polymer blend that is a single-phase structure. In ...

  9. Homogenization (chemistry) - Wikipedia

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

    Homogenization or homogenisation is any of several processes used to make a mixture of two mutually non-soluble liquids the same throughout. [2] This is achieved by turning one of the liquids into a state consisting of extremely small particles distributed uniformly throughout the other liquid.
