  2. 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 ...

  3. 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.

  4. Homogenization (chemistry) - Wikipedia

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

    Homogenization (from "homogeneous;" Greek, homogenes: homos, same + genos, kind) [5] is the process of converting two immiscible liquids (i.e. liquids that are not soluble, in all proportions, one in another) into an emulsion [6] (Mixture of two or more liquids that are generally immiscible).

  5. Homogeneous catalysis - Wikipedia

    en.wikipedia.org/wiki/Homogeneous_catalysis

    In chemistry, homogeneous catalysis is catalysis where the catalyst is in same phase as reactants, principally by a soluble catalyst in a solution. In contrast, heterogeneous catalysis describes processes where the catalysts and substrate are in distinct phases, typically solid and gas, respectively. [ 1 ]

  6. Homogeneity (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Homogeneity_(disambiguation)

    Homogeneous catalysis, a sequence of chemical reactions that involve a catalyst in the same phase as the reactants Homogeneous (chemistry) , a property of a mixture showing no variation in properties Homogenization (chemistry) , intensive mixing of mutually insoluble substance or groups of substance to obtain a soluble suspension or constant

  7. Nucleation - Wikipedia

    en.wikipedia.org/wiki/Nucleation

    For homogeneous nucleation the nucleus is approximated by a sphere, but as we can see in the schematic of macroscopic droplets to the right, droplets on surfaces are not complete spheres and so the area of the interface between the droplet and the surrounding fluid is less than a sphere's . This reduction in surface area of the nucleus reduces ...

  8. Homogeneous differential equation - Wikipedia

    en.wikipedia.org/wiki/Homogeneous_differential...

    A linear differential equation is homogeneous if it is a homogeneous linear equation in the unknown function and its derivatives. It follows that, if φ(x) is a solution, so is cφ(x), for any (non-zero) constant c. In order for this condition to hold, each nonzero term of the linear differential equation must depend on the unknown function or ...

  9. Dispersion (chemistry) - Wikipedia

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

    A solution describes a homogeneous mixture where the dispersed particles will not settle if the solution is left undisturbed for a prolonged period of time. 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 ...
