colloids, plural;
  1. Of the nature of, relating to, or characterized by a colloid or colloids

Noun
  1. A homogeneous, noncrystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension

  2. A substance of gelatinous consistency

  1. a mixture with properties between those of a solution and fine suspension
  2. (colloidal) of or relating to or having the properties of a colloid
  3. A colloid is a substance microscopically dispersed evenly throughout another one.
  4. A stable system of two phases, one of which is dispersed in the other in the form of very small droplets or particles; An intimate mixture of two substances one of which, called the dispersed phase (or colloid), is uniformly distributed in a finely divided state throughout the second substance ...
  5. Colloidal describes atoms or molecules dispersed in a gas, liquid or solid, which resist sedimentation (setting to the bottom), diffusion (spreading out), and filtration.
  6. (Colloidal) A gel-like mass which does not allow the transfer of ions
  7. (Colloidal) Condition of matter depicted by its even distribution (solution) of microscopic particles with a diameter of 1 to 100 nm in a dispersing substance. Minerals are present in plants in colloidal form.
  8. (Colloidal) Most colloid chemists restrict the term “colloidal” to particles that have diameters from 1 to 100 millimicrons (mµ), but soil scientists set the upper limit as high as 1,000; 2,000; or even 5,000µ (= 5µ = 0.005 mm). ...
  9. (Colloidal) a colloid that has a continuous liquid phase in which a solid is suspended in a liquid
  10. (Colloidal) contains clay particles with negative electromagnetic charges, that can bind sandy soils together and aid their nutrient retention properties.
  11. (colloidal) involving a state of subdivision of a solid or liquid into particles or droplets with diameters roughly in the range from 1 nm to 1 μm
  12. (colloids) Very small, finely divided solids (particles that do not dissolve) that remain dispersed in a liquid for a long time due to their small size and electrical charge. When most of the particles in water have a negative electrical charge, they tend to repel each other. ...
  13. (colloids) finely divided solids which will not settle but which may be removed by coagulation or biochemical action.
  14. (Colloids) Very small particles in suspension, e.g. clays.
  15. (12.10 Colloids) In colloids, the particles of dispersed matter range in size from about 1 to 1000 nm. One way that colloids differ from solutions is that colloids scatter light, a phenomenon known as the Tyndall effect, and true solutions do not. Many common materials are colloidal.
  16. (Colloids) Finely divided material, less than 0.5 micron (0.00002 in.) in size, gelatinous, highly absorbent, and sticky when moistened.
  17. (Colloids) In soils, small particles with very high surface-to-volume ratios formed by the combination of organic and mineral materials. Surface characteristics of soil colloids determine the physical and chemical characteristics of soils.
  18. (Colloids) Material with finely distributed solid particles that forms one of the key foundations of chemical nanotechnology.
  19. (Colloids) Microscopic particles including solids, liquids and gases. Colloids most often refer to large organic molecules, but sometimes refer to smaller molecules such as phenolics, pigmented tannins, and tannins. Colloids contribute to a wine’s viscosity. ...
  20. (Colloids) Microscopic suspended beads which form in aqueous solutions, generally composed of materials which are not very soluble but which have affinity for each other and can build stable microscopic structures. ...
  21. (Colloids) Miniature cells peculiar to meats, fish, and poultry which, If disrupted, cause food to become rancid. Low temperatures minimize this action.
  22. (Colloids) Plasma protein albumin and synthetic complex carbohydrate solutions. A one to one blood loss replacement, to expand blood volume and pull tissue into the blood stream
  23. (Colloids) Small particles suspended in a liquid by thermal agitation. That is, colloidal particles are sufficiently small that collisions with the molecules of the liquid in which they are immersed are sufficient to keep them from sinking or floating under the influence of gravity. ...
  24. (Colloids) Small undissolved particles (small enough to pass through a filter) suspended in coffee.
  25. (Colloids) The cataloged resource pertains to the structure and properties of colloids—suspensions of particles in dispersing media.
