  2. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension).

  3. Interface and colloid science - Wikipedia

    en.wikipedia.org/wiki/Interface_and_colloid_science

    Milk is an emulsified colloid of liquid butterfat globules of 0.1 to 10 micrometer dispersed within a water-based solution.. Interface and colloid science is an interdisciplinary intersection of branches of chemistry, physics, nanoscience and other fields dealing with colloids, heterogeneous systems consisting of a mechanical mixture of particles between 1 nm and 1000 nm dispersed in a ...

  4. APA style - Wikipedia

    en.wikipedia.org/wiki/APA_style

    APA style (also known as APA format) is a writing style and format for academic documents such as scholarly journal articles and books. It is commonly used for citing sources within the field of behavioral and social sciences , including sociology, education, nursing, criminal justice, anthropology, and psychology.

  5. Colloidal crystal - Wikipedia

    en.wikipedia.org/wiki/Colloidal_crystal

    A colloidal crystal is an ordered array of colloidal particles and fine grained materials analogous to a standard crystal whose repeating subunits are atoms or molecules. [1] A natural example of this phenomenon can be found in the gem opal , where spheres of silica assume a close-packed locally periodic structure under moderate compression .

  6. Category:Colloids - Wikipedia

    en.wikipedia.org/wiki/Category:Colloids

    Colloidal System: Finely divided particles of any substance with diameter lying within 1-100 nm range dispersed in any medium constitute what is termed a "colloidal system solution". It is a two phase system.

  7. Colloidal silica - Wikipedia

    en.wikipedia.org/wiki/Colloidal_silica

    Colloidal silicas are most often prepared in a multi-step process where an alkali-silicate solution is partially neutralized, leading to the formation of silica nuclei. The subunits of colloidal silica particles are typically in the range of 1 to 5 nm. Whether or not these subunits are joined depends on the conditions of polymerization.

  8. Suspension (chemistry) - Wikipedia

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

    In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not ...

  9. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    A colloid is a mixture which has particles of one phase dispersed or suspended within an other phase. The term applies only if the particles are larger than atomic dimensions but small enough to exhibit Brownian motion , with the critical size range (or particle diameter) typically ranging from nanometers (10 −9 m) to micrometers (10 −6 m ...
