colloidal system

[kə′lȯid·əl ′sis·təm]
(chemistry)
An intimate mixture of two substances, one of which, called the dispersed phase (or colloid), is uniformly distributed in a finely divided state through the second substance, called the dispersion medium (or dispersing medium); the dispersion medium or dispersed phase may be a gas, liquid, or solid. Also known as colloidal dispersion; colloidal suspension.

The device is especially suited to the measurement of colloidal systems and macromolecules in solution as well as more traditional applications found in the chemical industry.
Applications such as emulsions (pharmaceutical and others), dispersions, and suspensions and CMP (chemical mechanical planarization) slurries all share one common problem: a few oversize particles in any of these mostly submicron colloidal systems spell disaster.

We will develop our current work on actively driven colloidal systems to selectively test aspects of the biological scenarios, and start a new line of investigation in our lab, with cell culture experiments to validate these findings; we will understand the onset of collective dynamics (new physics), and how cilia waves are robust against fluctuations in cilia beat frequency, spatial arrangement and fluid rheology.
The book finishes with treatment of colloidal systems including emulsions, foams, and slurries, as well as the processes of wetting and hydrophobization, basic rheology, and some specific applications.
